The Illnesses You’re Most Likely to Encounter

Most older adults are managing not one health condition but several. The picture is often complex: multiple chronic conditions, multiple medications, multiple specialists who may or may not be communicating with each other. Understanding the conditions most commonly encountered in elder care — what they are, how they progress, and what they mean for caregiving — makes you a more effective advocate and a more informed partner in your parent’s care. This chapter covers the conditions you are most likely to encounter. You will notice that it reads differently from the rest of this book. That is intentional. The chapters on conversation, grief, housing, and family conflict are written in a personal voice because those experiences are personal — they live in the emotional territory that words like grace and grit are meant to address. This chapter is written as a reference, because when your parent receives a diagnosis, what you need is information you can act on. Each section is self-contained. You do not have to read this chapter straight through. Use the headings to find what is relevant to your situation right now, and return when something new arises. As always, consult healthcare professionals for guidance specific to your parent — this chapter gives you the foundation to ask better questions and understand the answers you receive. Dementia and Alzheimer's Disease Parkinson's Disease — A Progressive Journey Dementia is not a single disease but a group of symptoms affecting memory, thinking, and social abilities severely enough to interfere with daily life. Alzheimer's disease accounts for 60 to 80 percent of dementia cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. For caregivers, the type of dementia affects what to expect and how to plan, though many of the daily caregiving strategies apply across types. The caregiver's experience of dementia is covered in depth in Chapter 15. This section provides the essential overview: what to watch for, when to seek evaluation, and what the diagnosis means for your role going forward. Early warning signs: Memory loss that disrupts daily life (not just occasionally forgetting names), difficulty planning or solving problems, confusion with time or place, trouble understanding visual images or spatial relationships, new problems with words in speaking or writing, misplacing things and being unable to retrace steps, decreased or poor judgment, withdrawal from social activities, changes in mood or personality. What the diagnosis process looks like: Diagnosis involves cognitive testing, physical examination, blood tests to rule out treatable causes (thyroid disease, vitamin B12 deficiency, medication side effects), and often brain imaging. A specialist — neurologist, geriatrician, or geriatric psychiatrist — provides the most thorough evaluation. What a diagnosis means for caregiving: A dementia diagnosis triggers a cascade of planning needs: legal documents (power of attorney, healthcare proxy) should be completed while your parent can still participate meaningfully; driving should be evaluated formally; home safety needs assessment; support systems need building. The time between early diagnosis and the need for full-time care is often measured in years — use that time to prepare. See Chapter 15 for the complete dementia caregiving guide. Parkinson's disease is a progressive neurological condition affecting approximately one million Americans, with 60,000 new diagnoses each year. Most people associate it with tremors — the characteristic shaking of the hand or limb at rest — but Parkinson's is far more complex than its most visible symptom, and caregivers who understand the full picture are much better equipped for what lies ahead. What Parkinson's Actually Is Parkinson's results from the progressive loss of neurons in a brain region that produces dopamine, a neurotransmitter critical for coordinating smooth, controlled movement. As dopamine levels drop, movement becomes increasingly difficult to initiate, control, and sustain. The disease progresses slowly over years and decades, and its rate of progression varies significantly from person to person. The motor symptoms of Parkinson's include tremor (usually at rest, often starting in one hand), rigidity (stiffness in muscles and joints), bradykinesia (slowness of movement), and postural instability (difficulty with balance and coordination). Non-motor symptoms — which families are frequently unprepared for — include cognitive changes, depression and anxiety, sleep disturbances, constipation, and problems with swallowing and speech. What Families Most Need to Know Medication timing is not flexible. Levodopa (often prescribed as carbidopa-levodopa, brand name Sinemet) is the primary medication for Parkinson's motor symptoms. It must be taken on a precise schedule — often multiple times per day — because its effects wear off predictably between doses. Missing a dose or taking it late can cause significant worsening of symptoms, sometimes dramatically so. Hospitals are notorious for not administering Parkinson's medications on time. If your parent is hospitalized, advocate aggressively for their medications to be given on their exact schedule. Bring the pill bottles. Know the times. Ask every shift. Falls are the most serious immediate risk. Parkinson's significantly impairs balance and the ability to catch oneself from a fall. Falls are the leading cause of serious injury in Parkinson's patients. Home safety modifications — removing all fall hazards, installing grab bars, ensuring good lighting, eliminating rugs — are essential from early in the diagnosis. A physical therapist experienced with Parkinson's can teach specific techniques to reduce fall risk. Swallowing difficulties develop over time. As Parkinson's progresses, the muscles controlling swallowing can be affected — a condition called dysphagia. This creates a risk of aspiration — food or liquid entering the airway — which can lead to aspiration pneumonia, a serious and potentially life-threatening complication. Signs of swallowing problems include coughing or choking while eating, a wet or gurgling voice after swallowing, and recurring pneumonia. A speech-language pathologist can evaluate swallowing and recommend dietary modifications — thickened liquids, modified food textures — that significantly reduce the risk. Communication changes. Parkinson's affects the voice — producing a soft, monotone, or breathy quality — and facial muscles, reducing expression in a way that can make a person appear emotionally flat or disengaged when they are not. This is called hypomimia. Be aware that your parent's face may not show what they are feeling. Ask directly. A speech-language pathologist can help with voice projection exercises. Cognitive changes and dementia. Parkinson's disease dementia develops in a significant portion of patients over the course of the illness, typically in later stages. It presents differently from Alzheimer's — more prominent visual hallucinations, more fluctuating alertness — and requires specific management. Not every person with Parkinson's develops dementia, and its appearance does not mean the end of a meaningful life. Sleep is severely disrupted. People with Parkinson's frequently experience REM sleep behavior disorder — acting out dreams physically, sometimes violently — as well as restless legs, frequent waking, and excessive daytime sleepiness. This affects the caregiver's sleep as well. Addressing sleep disorders in Parkinson's is important for both your parent's health and your own sustainability as a caregiver. Care Team for Parkinson's Parkinson's care is optimally managed by a neurologist specializing in movement disorders, not a general neurologist. If your parent's diagnosis is being managed by a general practitioner or a neurologist without movement disorder specialization, ask for a referral. The Parkinson's Foundation (parkinson.org, 1-800-473-4636) operates a helpline and can help locate movement disorder specialists. Many offer telehealth consultations, which is particularly valuable when travel becomes difficult. Heart Disease Heart disease is the leading cause of death in the United States and becomes increasingly common with age. It encompasses several distinct conditions, including coronary artery disease, heart failure, and arrhythmias, each of which affects daily life differently. For a parent with heart disease, the caregiver’s role includes understanding and supporting their medication regimen (which is typically extensive and essential), recognizing warning signs that require medical attention, supporting appropriate lifestyle modifications, and managing the activity limitations that heart disease often imposes. Warning signs of a cardiac event that require immediate emergency response: chest pain or pressure, pain radiating to the arm or jaw, shortness of breath at rest, sudden severe sweating, lightheadedness, or a sense of impending doom. Know these. Post them somewhere visible. Know that heart attack symptoms in older adults and in women often present differently than the classic chest-clutching picture — more subtly, with fatigue, nausea, or back pain. Heart failure — the condition in which the heart cannot pump efficiently enough to meet the body’s needs — requires monitoring for fluid retention, which presents as sudden weight gain, swelling in the ankles and legs, and increasing shortness of breath. Many cardiologists ask heart failure patients to weigh themselves daily and call if weight increases more than two to three pounds in a day or five pounds in a week. Supporting your parent in maintaining this monitoring routine is a concrete, practical contribution to managing the condition. Atrial Fibrillation — The Heart Rhythm Problem That Raises Stroke Risk Atrial fibrillation — commonly called AFib — is the most common heart rhythm disorder in older adults, affecting roughly 9% of people over 65 and increasing in prevalence with age. It occurs when the upper chambers of the heart beat chaotically rather than with a coordinated rhythm, which reduces the heart's pumping efficiency and, critically, allows blood to pool and form clots. Those clots can travel to the brain, causing a stroke. AFib accounts for approximately one in five strokes in older adults. What caregivers need to know: Many people with AFib have no symptoms at all — it is discovered incidentally on an EKG during a routine exam. Others experience palpitations (a fluttering or racing feeling in the chest), shortness of breath, fatigue, or lightheadedness. Neither the presence nor the absence of symptoms reliably predicts stroke risk. Blood thinners are the most important medication: The primary goal in treating AFib is stroke prevention, achieved through anticoagulant medications — blood thinners. Common options include warfarin (Coumadin) and newer anticoagulants such as apixaban (Eliquis), rivaroxaban (Xarelto), and dabigatran (Pradaxa). These medications significantly reduce stroke risk but increase bleeding risk. Managing blood thinners requires awareness of interactions with other medications, foods (particularly vitamin K-rich foods with warfarin), and activities that carry injury risk. Falls and blood thinners: A parent on blood thinners who falls faces a serious risk of dangerous bleeding — internally or externally. This creates a genuine tension between stroke prevention (stay on the blood thinner) and injury prevention (reduce fall risk). Discuss fall prevention strategies explicitly with the physician. Home safety modifications take on added urgency. Rate control vs. rhythm control: Beyond blood thinners, treatment may aim to control the heart rate (rate control) or restore a normal rhythm (rhythm control, sometimes through cardioversion or ablation procedures). The right approach depends on your parent's specific situation. Ask the cardiologist to explain the goal of each medication and procedure in plain terms. Watch for: New or worsening shortness of breath, sudden severe fatigue, chest pain, or any stroke symptoms (FAST — Face, Arm, Speech, Time) — which warrant immediate 911 contact. If your parent is on blood thinners, any significant fall, head injury, or unusual bruising should be reported to the physician promptly. Stroke — What Every Family Member Must Know Stroke is the fifth leading cause of death in the United States and the leading cause of long-term adult disability. It is also one of the most time-sensitive medical emergencies that exists — the difference between recognizing a stroke and acting within minutes versus waiting to see if symptoms improve can determine whether your parent walks out of the hospital or spends the rest of their life in a wheelchair. Every adult in a family with aging parents needs to know the warning signs and what to do. Recognizing a Stroke — FAST The FAST acronym is the most reliable and widely taught stroke recognition tool. Know it and teach it to everyone in your family. F — Face drooping: Ask your parent to smile. Is one side of the face drooping or numb? An uneven smile is a warning sign. A — Arm weakness: Ask your parent to raise both arms. Does one arm drift downward or is there weakness on one side? S — Speech difficulty: Is your parent's speech slurred, garbled, or strange? Can they repeat a simple sentence correctly? T — Time to call 911: If you observe any of these signs, call 911 immediately. Do not drive to the hospital. Do not wait to see if it passes. Every minute matters. Other stroke symptoms include: sudden severe headache with no known cause (sometimes described as the worst headache of a person's life), sudden vision changes in one or both eyes, sudden dizziness or loss of balance, sudden numbness or weakness on one side of the body. Any of these symptoms, appearing suddenly, warrant an immediate 911 call. Time is brain. With every minute of a stroke untreated, approximately 1.9 million neurons die. The clot-dissolving medication tPA can dramatically limit stroke damage — but only if administered within 4.5 hours of symptom onset. Getting to the hospital fast is the single most important thing you can do. At the Hospital — What Happens and What You Need to Know When your parent arrives at the emergency room with stroke symptoms, the team will act quickly. A brain imaging scan — typically a CT scan — will be done immediately to determine whether the stroke is ischemic (caused by a clot, which is roughly 87% of strokes) or hemorrhagic (caused by bleeding, which is roughly 13%). This distinction is critical because the treatments are opposite — clot-busting medication that helps an ischemic stroke would be dangerous in a hemorrhagic stroke. For ischemic stroke, if your parent arrives within the treatment window and qualifies, the team may administer tPA (tissue plasminogen activator) — a clot-dissolving medication that can significantly reduce disability. For larger clots, a mechanical thrombectomy — a procedure to physically remove the clot — may be possible within a longer window of up to 24 hours from symptom onset in some cases. Ask the stroke team directly what options are available and what the risks and benefits are for your parent's specific situation. After Stroke — The Caregiving Reality Stroke recovery is highly individual. Some people recover most function within weeks; others live with significant permanent disability. The nature and extent of deficits depends on which part of the brain was affected and how much tissue was damaged. Aphasia: Damage to language areas of the brain can cause aphasia — difficulty speaking, understanding speech, reading, or writing. Aphasia is not the same as cognitive impairment. Your parent may have full intelligence and awareness while being unable to produce or understand words. This is deeply frustrating for everyone. A speech-language pathologist is essential. Speak slowly and clearly, give time for responses, use simple words and yes/no questions, and never finish sentences for your parent unless asked. Paralysis and weakness: Weakness or paralysis on one side of the body (hemiplegia) is common. Physical and occupational therapy begin as soon as medically possible — often within 24 hours of a stroke — because early rehabilitation significantly improves outcomes. Advocate for the maximum amount of therapy available. Cognitive changes: Stroke can affect memory, attention, problem-solving, and emotional regulation. Post-stroke depression is extremely common — up to 30% of stroke survivors experience it — and is often underdiagnosed. Watch for persistent low mood, withdrawal, and loss of motivation, and raise it with the treatment team. Secondary stroke prevention: Having one stroke significantly increases the risk of another. The period immediately after a stroke is the highest-risk window. Your parent will likely be prescribed blood pressure medication, anticoagulants or antiplatelet agents, and may undergo cardiac evaluation. Adherence to these medications is critical and requires careful management. Home modifications: If your parent returns home after a stroke, significant modifications may be needed — grab bars, wheelchair accessibility, ramp installation, removal of fall hazards. An occupational therapist can conduct a home safety evaluation before discharge and recommend specific modifications. Caregiver impact: Stroke caregiving is among the most demanding forms of caregiving. The sudden onset — a parent who was fully functional yesterday may be significantly disabled today — means there is no gradual adjustment period. Caregiver burnout rates are high. The support resources in Chapter 22 and 23 are particularly relevant for stroke caregivers. Respiratory Conditions: COPD and Pneumonia Chronic obstructive pulmonary disease (COPD) — which includes chronic bronchitis and emphysema — is a progressive lung condition most commonly caused by a history of smoking. It causes breathlessness that worsens over time and limits physical activity. Managing COPD involves medications (inhaled bronchodilators and steroids), pulmonary rehabilitation, oxygen therapy when needed, and avoiding respiratory irritants including secondhand smoke. For caregivers, the most important skill in COPD management is recognizing exacerbations: acute worsening of breathlessness, increased cough and mucus production, or changes in the color of sputum. Exacerbations require prompt medical attention and are a leading cause of hospitalization and functional decline in people with COPD. Pneumonia — lung infection — is a serious risk for older adults, particularly those with COPD, heart disease, or diabetes, and those who are immunocompromised or have difficulty swallowing. Pneumococcal and annual influenza vaccinations significantly reduce risk. Know the symptoms: fever, chills, cough that may produce discolored mucus, shortness of breath, chest pain, and in older adults, confusion that may appear before respiratory symptoms. Pneumonia in an older adult requires prompt medical evaluation. Sleep Apnea — The Underdiagnosed Condition Affecting Heart and Brain Sleep apnea is a condition in which breathing repeatedly stops and starts during sleep, depriving the body of oxygen dozens or hundreds of times per night. It affects an estimated 30–80% of older adults to varying degrees, making it one of the most common conditions in this age group — and one of the most underdiagnosed. Many older adults and their families attribute the symptoms to normal aging when effective treatment is available. Signs that suggest sleep apnea: Loud snoring, witnessed episodes of stopped breathing during sleep, gasping or choking sounds during sleep, waking with a dry mouth or headache, excessive daytime sleepiness, difficulty concentrating, irritability, and frequent nighttime urination. A bed partner or caregiver is often the first to notice. Why it matters beyond disrupted sleep: Untreated sleep apnea significantly increases the risk of high blood pressure, heart disease, atrial fibrillation, stroke, and type 2 diabetes. It impairs cognitive function — contributing to memory problems and difficulty concentrating that can be mistaken for early dementia. In older adults already managing these conditions, untreated sleep apnea makes them harder to control. Diagnosis: Sleep apnea is diagnosed through a sleep study — either in a sleep lab or increasingly through a home sleep test, which is simpler and more accessible. If your parent's physician has not asked about sleep quality and snoring, raise it directly. This is especially important if your parent has high blood pressure, AFib, or cognitive concerns that are not fully explained by other conditions. Treatment: CPAP (continuous positive airway pressure) — a machine that delivers a steady stream of air through a mask to keep the airway open during sleep — is the most effective treatment and dramatically improves sleep quality, daytime alertness, and cardiovascular outcomes when used consistently. Many older adults resist CPAP initially; modern machines are quieter and masks are more comfortable than earlier versions. A brief trial with proper fitting often converts skeptics. Positional therapy and weight loss can help in milder cases. Arthritis Arthritis is among the most prevalent conditions in older adults, affecting more than half of Americans over 65. It is not a single disease but an umbrella term for over 100 conditions affecting the joints. Osteoarthritis — the wear-and-tear deterioration of cartilage — is the most common. Rheumatoid arthritis is an autoimmune condition affecting the joint lining and often involves more widespread inflammation. For caregivers, the practical impact of arthritis is everywhere. Arthritic hands make opening bottles, managing buttons and zippers, using keys, and handling small objects painful or impossible. This means simple daily tasks — preparing meals, managing medications, managing their own personal care — become difficult in ways that are easy to miss if you’re not specifically looking. When your parent seems to be struggling with something that should be easy, arthritis pain may be the reason they are not mentioning. Assistive devices designed for arthritic hands are widely available and genuinely helpful: jar openers, electric can openers, key turners, lever-style door and faucet handles, button hooks, long-handled reachers, and adaptive utensils. An occupational therapist can assess daily tasks and recommend specific devices based on your parent’s particular limitations. This is one of the most practical referrals available. Pain management for arthritis is an ongoing conversation with the physician. Over-the-counter pain relievers provide some relief but have limitations in older adults, particularly at higher doses or with extended use. Prescription options, physical therapy, topical treatments, and in some cases joint injections or surgery may be appropriate. The goal is pain management that allows your parent to remain as active and engaged as possible, because physical deconditioning accelerates the functional losses arthritis produces. Osteoporosis Osteoporosis — the progressive loss of bone density — makes bones fragile and significantly increases the risk of fractures. It is far more common in women than in men but affects both. Hip fractures in older adults with osteoporosis are serious events: they frequently require surgery, carry significant risks of complications and mortality, and often mark the beginning of a significant functional decline. Calcium and vitamin D are important for bone health at every age and become critical in later life. Adequate protein intake supports bone density. Weight-bearing exercise — walking, standing activities — stimulates bone maintenance. Medications including bisphosphonates can slow bone loss and reduce fracture risk in people with established osteoporosis. If your parent has not been screened for osteoporosis — a simple, painless bone density scan — this is worth raising at the next physician visit. Home safety modifications that reduce fall risk are the most important practical intervention for a parent with osteoporosis. A fall that would produce a bruise in a younger person may produce a fracture in a person with compromised bone density. Chapter Nine covers home safety modifications in detail. Diabetes Type 2 diabetes is extremely common in older adults, and its management becomes more complex with age. Blood sugar control is important but must be balanced carefully: the aggressive targets recommended for younger adults can be dangerous in older people, because hypoglycemia — dangerously low blood sugar — can cause falls, confusion, loss of consciousness, and serious injury. As a caregiver, understanding the basics of your parent’s diabetes management helps you recognize warning signs. Hypoglycemia presents as sudden shakiness, sweating, confusion, weakness, or anxiety. It requires immediate treatment with a fast-acting carbohydrate source — juice, glucose tablets, candy. Hyperglycemia — high blood sugar — presents more gradually as fatigue, increased thirst, frequent urination, or blurred vision. Foot care is critically important for people with diabetes, because diabetic neuropathy — nerve damage that reduces sensation in the feet — means injuries and infections may not be felt until they are advanced. Regular foot inspection, properly fitting footwear, and prompt attention to any cut, blister, or discoloration are standard parts of diabetic care that often fall to family caregivers. Chronic Kidney Disease — The Silent Condition That Affects Everything Else Chronic kidney disease (CKD) is the gradual loss of kidney function over time. The kidneys filter waste and excess fluid from the blood, regulate blood pressure, produce hormones that affect red blood cell production and bone health, and help maintain the body's chemical balance. When kidney function declines, all of these processes are affected. CKD is extremely common in older adults — affecting roughly 38% of adults over 65 — and is particularly important for caregivers to understand because it affects the safety and dosing of almost every other medication your parent takes. Why CKD matters for medication management: Many medications are cleared from the body through the kidneys. When kidney function is reduced, drugs that would otherwise be processed and eliminated accumulate to higher levels than intended — increasing both effectiveness and toxicity. Dosing adjustments are required for many common medications, including some antibiotics, pain medications, blood pressure drugs, and diabetes medications. Every time a new medication is prescribed, the physician and pharmacist should be aware of your parent's kidney function. The creatinine and GFR numbers: Kidney function is measured by blood tests — creatinine and estimated glomerular filtration rate (eGFR). The eGFR number tells you what percentage of normal kidney function remains. An eGFR above 60 is generally considered adequate; below 30 is severely reduced; below 15 typically requires dialysis or transplant. Know your parent's eGFR number and ask about it at each annual visit if CKD is present. Symptoms to watch for: CKD is often asymptomatic until quite advanced — hence its description as a silent condition. As it progresses, watch for: swelling in the legs and ankles, fatigue and weakness (often from anemia that accompanies CKD), changes in urination frequency or appearance, shortness of breath, nausea and loss of appetite, difficulty concentrating, and itching. Protecting remaining kidney function: Managing blood pressure and blood sugar — the two leading causes of CKD — directly slows progression. Avoiding NSAIDs (ibuprofen, naproxen) is important, as these medications reduce blood flow to the kidneys and can cause acute deterioration. Staying well-hydrated is important. Certain contrast dyes used in imaging studies can also harm the kidneys — always inform any imaging facility of your parent's kidney disease. Peripheral Neuropathy — When Nerves Stop Sending Reliable Signals Peripheral neuropathy is damage to the peripheral nerves — the nerves outside the brain and spinal cord that carry signals to and from the limbs and organs. It affects roughly 8% of older adults, with significantly higher rates among those with diabetes (diabetic neuropathy is the most common cause). Other causes include certain chemotherapy medications, vitamin B12 deficiency, alcohol use, and in some cases no identifiable cause. What it feels like: The most common presentation is numbness, tingling, or burning pain in the feet and hands — often described as a "glove and stocking" distribution. Some people experience sharp, shooting pains. Others lose sensation almost entirely, which is dangerous because they cannot feel injuries, pressure sores, or temperature extremes. Falls are the primary caregiving concern: Loss of sensation in the feet disrupts proprioception — the body's sense of where its limbs are in space — which is critical for balance. A parent with peripheral neuropathy may not feel the floor properly and may have significantly impaired balance even when otherwise physically capable. Fall prevention — appropriate footwear, home safety modifications, physical therapy for balance training — is the most important intervention. Foot care: A parent with neuropathy who cannot feel their feet is at serious risk of undetected wounds, pressure sores, and infections. Daily foot inspection is essential — check between the toes, on the soles, and around the heels for any cuts, blisters, redness, or swelling. This is particularly critical in diabetic neuropathy, where poor circulation compounds the problem. A podiatrist visit is worthwhile for ongoing foot care. Treatment: There is no cure for most peripheral neuropathy, but symptoms can be managed. Medications — gabapentin, pregabalin, duloxetine, certain antidepressants — can reduce pain. Vitamin B12 supplementation is indicated when deficiency is the cause. Physical therapy helps with balance and fall prevention. If chemotherapy is the cause, the physician may be able to modify the regimen. Depression: The Underdiagnosed Condition Depression in older adults is significantly underdiagnosed and undertreated, in part because both patients and caregivers tend to attribute its symptoms to other causes: “Of course she’s sad, she’s old.” But depression is not a normal or inevitable part of aging. It is a medical condition with effective treatments. And it is more common in older adults — particularly those managing chronic pain, significant functional loss, social isolation, or bereavement — than most families realize. Symptoms of depression in older adults may differ somewhat from classic presentations in younger people. Watch for: persistent sadness or emptiness, loss of interest in activities previously enjoyed, significant changes in appetite or sleep, withdrawal from people and activities, fatigue and loss of energy, difficulty concentrating or making decisions, expressions of hopelessness, and in older adults particularly, unexplained physical complaints. Depression affects cognitive function, physical health outcomes, and quality of life. It is not something to wait out or address with reassurance. If you observe these symptoms, raise them with the primary care physician. Effective treatment exists — therapy, medication, or a combination — and treatment matters. A parent who is being treated effectively for depression is not only happier; they are better positioned to engage with their own healthcare, maintain their nutrition and activity, and use the support that is available to them. Anxiety — The Condition That Hides Behind Physical Symptoms Anxiety disorders are among the most common mental health conditions in older adults, affecting roughly 10–15% of adults over 65 — and significantly underdiagnosed because anxiety in older adults frequently presents differently than in younger people. Rather than expressing worry or nervousness directly, an older adult with anxiety may present with physical symptoms: unexplained chest pain, gastrointestinal distress, fatigue, dizziness, or frequent requests for medical evaluation of symptoms that do not have a clear physical cause. Anxiety and depression frequently co-occur in older adults — up to 50% of older adults with depression also have significant anxiety, and vice versa. They are often treated together. If your parent has been diagnosed with depression, anxiety deserves specific attention as well. What anxiety looks like in older adults: Excessive worry about health, finances, family members, or falling. Avoidance of activities or situations previously enjoyed. Restlessness or irritability. Physical complaints — stomach problems, headaches, muscle tension — without a clear medical explanation. Sleep disturbance. Increased dependence on caregivers for reassurance. Health anxiety specifically: Some older adults develop significant anxiety focused specifically on their health — catastrophizing minor symptoms, frequently seeking medical reassurance, requesting tests and specialist referrals driven by fear rather than clinical necessity. This is not hypochondria in the dismissive sense — it is a real and treatable anxiety disorder that causes genuine suffering and can strain the relationship between the patient and their healthcare team. Treatment: Anxiety in older adults responds well to treatment. Cognitive behavioral therapy (CBT) is effective and preferred for older adults when available because it avoids medication side effects. Certain medications — particularly SSRIs and SNRIs — are also effective. Benzodiazepines (Valium, Xanax, Ativan) are commonly prescribed for anxiety but are not recommended for older adults due to significant risks: falls, cognitive impairment, dependence, and rebound anxiety. If your parent is being prescribed a benzodiazepine for anxiety, ask the physician whether alternatives have been considered. For caregivers: Caregiving itself is a significant source of anxiety, and an anxious parent can intensify caregiver anxiety in a cycle that is difficult to break. Managing your own anxiety — through support groups, therapy, and the self-care practices described in Chapter 22 — is not separate from your parent's care. It is part of it. Suicide in Older Adults — The Risk Nobody Talks About This section addresses something most caregiving books avoid entirely. Suicide among older adults is more common, more lethal, and less discussed than in any other age group. Adults 65 and older have among the highest suicide rates in the United States, and older white men have the highest rate of any demographic — higher than teenagers, higher than veterans. The primary reason most families don't know this is that it simply isn't talked about. If you are reading this because you are worried about your parent right now, skip to the section on what to do. If your parent has expressed suicidal thoughts, call 988 (the Suicide and Crisis Lifeline) immediately, or take them to the nearest emergency room. Do not leave them alone. 988 is the Suicide and Crisis Lifeline — available 24 hours a day, 7 days a week, by call or text. If you believe your parent is in immediate danger, call 911. Why Older Adults Are at Higher Risk The losses that accumulate with aging create a constellation of risk factors that are distinct from those in younger adults. Understanding them helps caregivers recognize warning signs that might otherwise be invisible. Loss of independence: The transition from self-sufficiency to needing help — with driving, with finances, with personal care — is experienced by many older adults as a fundamental loss of identity and purpose. For a person who defined themselves through their competence and self-reliance, this loss can feel unbearable. Chronic pain: Persistent, undertreated pain is one of the strongest predictors of suicidal ideation in older adults. Pain that disrupts sleep, limits activity, and has no clear end creates a sense of being trapped that is a serious risk factor. Assess whether your parent's pain is being adequately managed and advocate for better treatment if it isn't. Bereavement and isolation: Older adults frequently lose spouses, siblings, and close friends within short periods. The social world contracts at exactly the time when connection is most needed. Social isolation — living alone, limited mobility, reduced access to community — dramatically increases suicide risk. Depression left untreated: Depression in older adults is underdiagnosed and undertreated, as described in the previous section. Untreated depression is the single strongest predictor of suicide in this age group. If your parent is showing signs of depression, pursuing treatment is not just about quality of life — it is a safety issue. Access to lethal means: Older adults who attempt suicide are far more likely to complete it than younger adults — in part because they tend to use more lethal methods and in part because they are more physically vulnerable. If a firearm is present in the home and your parent is showing signs of serious depression or hopelessness, raising the subject of firearm safety — temporarily removing it, storing it securely — is an act of care, not an intrusion. A sense of being a burden: One of the most consistent findings in research on suicide in older adults is the feeling of being a burden to family members. A parent who says 'you would all be better off without me' or 'I don't want to be a burden' is expressing something that deserves to be taken seriously and addressed directly, not dismissed. Warning Signs in Older Adults The warning signs of suicidal ideation in older adults differ somewhat from those in younger people. Many older adults will not say directly that they want to die — they express it differently. Direct statements: Any statement about wanting to die, not wanting to be here anymore, being ready to go, or being tired of living should be taken seriously. These are not phrases to deflect or minimize. Giving things away: Giving away possessions — particularly meaningful or valuable items — to family members or friends can signal a person who believes they will not need them. Saying goodbye: Making unusual efforts to contact people they haven't spoken with in years, wrapping up unfinished business, saying things that sound like farewells. Withdrawal: Sudden or progressive withdrawal from people and activities they previously valued. Hopelessness: Statements that things will never get better, that there is no point, that the future holds nothing. Increased substance use: Escalating alcohol use in particular. Researching methods: Looking up information about medications, asking about medications in unusual ways, or expressing unusual interest in a firearm. How to Ask the Question Directly The most common reason family members don't ask directly about suicide is fear that asking will put the idea in their parent's mind. This fear is not supported by evidence. Asking directly about suicide does not increase risk. In most cases it provides relief — the person feels seen, less alone, and more able to talk honestly about what they are experiencing. Ask directly and without euphemism: "I've noticed you seem really low lately, and I'm worried about you. I need to ask you directly — are you thinking about ending your life?" Then listen without interrupting, without minimizing, and without immediately rushing to fix or reassure. Let them speak. If your parent says yes, or if they express thoughts of not wanting to be here: do not leave them alone. Remove access to lethal means if you can do so safely. Call 988 together, or take them to the emergency room. Tell their physician as soon as possible — this is information a treating physician needs to know. If your parent says no: Thank them for answering honestly. Tell them you are asking because you love them and you're paying attention. Tell them you want to know if that ever changes. Then follow up — on the underlying depression, on the social isolation, on the pain, on whatever is driving the despair. After a Suicide Loss If you have lost a parent to suicide, the grief is among the most complex and isolating forms of bereavement. It often carries guilt, anger, unanswerable questions, and a stigma that can make it difficult to talk about openly. You may find yourself replaying conversations, looking for signs you missed, wondering what you could have done differently. The American Foundation for Suicide Prevention (afsp.org) provides resources specifically for survivors of suicide loss, including support groups and counseling referrals. The 988 Lifeline also provides support for those bereaved by suicide. You do not have to carry this alone, and you do not have to have answers to questions that may not have answers. Alcohol Use Disorder in Older Adults — The Problem Families Overlook Alcohol use disorder in older adults is dramatically underrecognized — by families, by physicians, and often by the older adults themselves. It is estimated that 10–15% of older adults drink at levels that put their health at risk, and problem drinking in this age group frequently goes unidentified because it looks different than it does in younger people, because families are reluctant to raise it, and because physicians rarely screen for it systematically. Alcohol affects older adults more severely than younger adults at the same consumption level. Reduced body water content means higher blood alcohol concentration from the same amount. Slower liver metabolism means alcohol stays in the system longer. Interactions with medications — which most older adults take multiple of — can be serious and sometimes life-threatening. Why it develops or worsens in older age: Retirement removes structure and social connection. Loss of a spouse or close friends creates grief that alcohol temporarily numbs. Chronic pain — undertreated — is self-medicated with alcohol. Isolation amplifies dependence. Many older adults who were moderate drinkers earlier in life gradually increase consumption without recognizing the change. Signs families often miss: Increased irritability or mood swings, especially in late afternoon or evening. Frequent falls or accidents without clear explanation. Cognitive changes — confusion, memory problems — that worsen and then improve cyclically. Hiding bottles or minimizing consumption when asked. Physical symptoms: tremors in the morning, flushing, repeated gastrointestinal complaints. Social withdrawal. Resistance to any discussion of drinking. The medication interaction danger: Alcohol interacts dangerously with many medications commonly prescribed to older adults — blood thinners (increased bleeding risk), sleep medications and sedatives (dangerous sedation), blood pressure medications, diabetes medications, opioid pain medications, and many others. A parent who drinks regularly and takes multiple medications is at genuine risk of serious harm from interactions that a physician may not be monitoring. How to raise it: This is one of the most difficult conversations in caregiving — but it is one worth having. Approach it from a position of concern rather than accusation: 'I've noticed you've been drinking more than you used to, and I'm worried about how it might be affecting your health and your medications. Can we talk about that?' A physician can screen using the AUDIT-C tool and provide a brief intervention that research shows is effective even without formal treatment. Treatment: Alcohol use disorder in older adults responds well to treatment when it is identified. Motivational interviewing, outpatient counseling, and support groups (AA is widely available; SMART Recovery is an evidence-based alternative) are all effective. Medically supervised detoxification may be needed for those with heavy dependence — alcohol withdrawal in older adults can be medically serious and should not be managed alone. The SAMHSA National Helpline (1-800-662-4357) is free, confidential, and available 24 hours a day. Cancer — What Families Need to Know Cancer is among the most common serious diagnoses in older adults and one of the most emotionally and practically complex a family will face. More than 60 percent of all cancers are diagnosed in people over the age of 65. For adult children in a caregiving role, a parent's cancer diagnosis is a turning point that touches everything — medical decisions, daily logistics, family dynamics, financial planning, and the most fundamental questions about how your parent wants to live and what they most value. Cancer is not one disease. It is hundreds of diseases with different trajectories, different treatments, and different implications for a parent's daily life and long-term prognosis. What is true for early-stage breast cancer is not true for advanced pancreatic cancer. What is manageable for a 72-year-old in good general health may be overwhelming for an 82-year-old managing multiple other conditions. The guidance in this section is not diagnosis-specific — it is about how to navigate the caregiving role across the range of what cancer can mean. How Cancer Presents Differently in Older Adults Cancer in older adults frequently behaves differently than cancer in younger patients, and treatment decisions that are straightforward at fifty become genuinely complex at eighty. Several factors make this true. Comorbidities change the calculation. Most older adults with cancer are also managing heart disease, diabetes, kidney disease, arthritis, or other conditions. These conditions affect what treatments are tolerable, what side effects are likely, and what the realistic goals of treatment are. A chemotherapy regimen that is well-tolerated in a healthy sixty-year-old may be dangerous in an eighty-year-old with diminished kidney function. Functional status matters as much as age. Oncologists increasingly look not just at a patient's age but at their functional status — their ability to manage daily activities, their cognitive sharpness, their nutritional status, and their overall resilience. Two patients of the same age with the same diagnosis may have very different treatment options based on their functional health. A geriatric assessment — conducted by a geriatric oncologist or a geriatric care specialist — can help clarify what treatments are realistic. Fatigue hits harder and lasts longer. Cancer-related fatigue in older adults is often more severe and slower to resolve than in younger patients. It is not ordinary tiredness. It does not respond to rest in the way ordinary tiredness does. It affects thinking, mood, appetite, and the ability to do the simplest tasks. Families who understand this going in are far better equipped to support their parent through treatment without misreading the fatigue as depression or giving up. Polypharmacy creates risk. An older adult taking eight or ten medications for various conditions faces real risks of dangerous interactions with cancer treatments. A complete medication review by the oncology team — including over-the-counter medications, vitamins, and supplements — is essential before any treatment begins. The First Two Weeks After Diagnosis — What to Do The period immediately following a cancer diagnosis is disorienting for everyone. Your parent has just received information that reorganizes everything they thought they knew about their future. You are trying to understand the medical situation, manage your own emotional response, and figure out how to be helpful without taking over. Here is what actually matters in those first two weeks. Do not make permanent decisions under acute shock. The first conversations after diagnosis are for understanding, not for deciding. Unless there is a genuine medical emergency requiring immediate action, most treatment decisions can wait ten to fourteen days while your parent — and your family — processes what has been told to them. A second opinion is almost always worth getting before major treatment decisions are finalized. Get a second opinion. This is not disloyal to the diagnosing physician. It is standard practice in oncology. Major cancer centers — Mayo Clinic, MD Anderson, Memorial Sloan Kettering, and others — offer second opinion consultations either in person or remotely. Many insurance plans cover second opinions. For a significant diagnosis, a second perspective can confirm the treatment plan, suggest alternatives, or occasionally reveal a different interpretation of the pathology. Always get one. Ask about a geriatric oncologist. Geriatric oncology is a subspecialty focused specifically on the intersection of cancer and aging. A geriatric oncologist conducts a comprehensive assessment that looks at the whole person — not just the tumor — and helps calibrate treatment decisions to what your parent can realistically tolerate and benefit from. Not every cancer center has geriatric oncologists, but many do, and the consultation is worth requesting. Establish one family point of contact. Designate one person — usually the adult child most involved in the caregiving — as the primary contact with the medical team. This prevents conflicting information from reaching different family members, ensures someone who knows the full picture is at every appointment, and reduces the burden on your parent to communicate the same information repeatedly to multiple family members who are calling separately. Start a medical binder. Cancer treatment involves a large volume of medical information — pathology reports, imaging results, lab values, medication lists, appointment notes, and treatment records. A dedicated binder that travels to every appointment, organized chronologically with tabs, makes every subsequent encounter more efficient and prevents critical information from being lost. Questions to Ask the Oncologist These questions are not all for the first appointment — spread them across the first several conversations as the treatment plan takes shape. About the diagnosis: What type and stage of cancer is this? What does the stage mean for how the disease is likely to progress? Has the cancer spread, and if so, where? About treatment goals: Is the goal of treatment to cure the cancer, to control it, or to manage symptoms? What does success look like for this treatment? What happens if treatment does not work as hoped? About treatment options: What are all the treatment options — surgery, chemotherapy, radiation, immunotherapy, targeted therapy, hormonal therapy, clinical trials? What are the expected benefits and risks of each? What would you recommend and why? About my parent's specific situation: How does my parent's age and overall health affect the treatment options? Are there treatments that would be appropriate for a younger patient that are not appropriate here? What is the likely impact on daily functioning and quality of life? About what to expect: What are the most likely side effects and how are they managed? What symptoms should prompt an immediate call or emergency room visit? What does a typical week look like during this treatment? About the future: What are the realistic goals over the next six months, one year, five years? When will we know if the treatment is working? What are the signs that would lead you to recommend a different approach? Managing Daily Life During Treatment Cancer treatment — particularly chemotherapy and radiation — can dramatically affect your parent's daily life. Understanding what to expect makes it possible to prepare rather than react. Fatigue management: The single most important thing family members can do is stop expecting a parent in treatment to function at their usual level. Fatigue is real, it is profound, and it is not a sign of weakness or giving up. Help your parent conserve energy for what matters most to them. Identify the time of day when they feel best and protect that time for meaningful activity. Encourage rest without guilt. Nutrition and appetite: Many cancer treatments affect appetite, taste, and the ability to eat. Food that tasted good before treatment may taste metallic, too sweet, or nauseating during chemotherapy. Small, frequent meals are usually better tolerated than large ones. Calorie-dense foods — nuts, avocados, whole milk dairy — help maintain weight when appetite is poor. If significant weight loss occurs, ask for a referral to an oncology dietitian. Infection risk: Many chemotherapy agents suppress the immune system, making your parent vulnerable to infections that a healthy immune system would easily fight. Understand your parent's neutrophil count — the white blood cell type most critical for fighting bacterial infection — and know the threshold at which you should call the oncology team. A fever of 100.4°F or above during chemotherapy is a medical emergency that requires immediate contact with the oncology team. This is not an exaggeration. Transportation: Cancer treatment often requires multiple appointments per week for weeks or months. Driving is often not possible during treatment due to fatigue, side effects, or medications. Build a reliable transportation plan before treatment begins — family rotation, volunteer driver programs through the American Cancer Society (1-800-227-2345), or HCBS waiver transportation if your parent qualifies. Medication management: Cancer treatment adds new medications — anti-nausea drugs, steroids, growth factors, pain management — to whatever your parent was already taking. Keep the medication list meticulously updated and bring it to every appointment. Ask the oncology pharmacist about interactions with existing medications at every new prescription. When the Goal Shifts — From Treatment to Comfort One of the most important and most difficult conversations in cancer caregiving is the one about goals of care — what the treatment is trying to achieve, and when the cost of treatment begins to outweigh what it offers. Many families never have this conversation explicitly. They proceed through treatments sequentially — first one regimen, then another when that stops working, then another — without stepping back to ask whether continued treatment is serving their parent's goals and values. The result is sometimes that a parent spends the last months of their life in treatment when they might have chosen differently if they had been explicitly offered the choice. The most important question in cancer caregiving is not 'what else can be done?' It is 'what does my parent most want their remaining time to look like?' These are not the same question. When a cancer is no longer responding to treatment, or when the side effects of treatment are affecting quality of life more than the cancer itself, the oncology team may raise the possibility of transitioning to palliative care only — focusing entirely on comfort, symptom management, and quality of life rather than attempting to control the cancer. Palliative care is not the same as hospice. Palliative care can be provided alongside curative or disease-modifying treatment at any stage of illness. Hospice is a specific program of comfort-focused care for people who have decided to stop attempting to cure or control their illness and focus entirely on quality of life in the time remaining. Hospice for cancer patients often includes expert pain and symptom management that makes the final weeks and months far more comfortable than families expect. Research consistently shows: cancer patients who enroll in hospice earlier — rather than as a last resort — often live as long as or longer than comparable patients who continue aggressive treatment, and consistently report higher quality of life. Hospice is not giving up. It is a different and often more honest approach to the time that remains. When the goals-of-care conversation needs to happen, it belongs between your parent, their oncologist, and the family members your parent wants involved. Your role as a caregiver is to support your parent in having this conversation clearly and honestly — not to make the decision for them, and not to avoid the topic because it is painful. If your parent has completed an Advance Directive, the values expressed there are the foundation for this conversation. The Emotional Landscape of Cancer Caregiving A parent's cancer diagnosis reorganizes the adult child's emotional world in ways that are difficult to fully articulate. The fear is constant and multi-layered — fear for your parent, fear of their suffering, fear of loss, fear of your own inadequacy to handle what is coming. The grief begins before the death, in the form of anticipatory grief — mourning the future that is changing before it arrives. "My mother was diagnosed in October. By December I had already grieved her death a dozen times. She was still here, still herself, still making me laugh — and I was already practicing being without her. I didn't know that was a real thing until I found a name for it." — A caregiver Anticipatory grief is real, it is common in cancer caregiving, and it can be processed. It does not mean you have given up on your parent. It means you are facing the truth of the situation honestly, which is what allows you to be fully present during the time that remains. Cancer caregiving also tends to produce a specific kind of helplessness — the experience of watching someone you love suffer and being unable to stop it. There is no correct response to this. What helps most caregivers is focusing on what is within reach: being present, managing what can be managed, asking what your parent needs rather than assuming, and allowing your parent to direct their own experience as much as possible. What not to say: "Stay positive" — this places the burden of their outcome on your parent's attitude. "Everything happens for a reason" — this is rarely comforting and often enraging to someone in pain. "You're so strong" — this can make your parent feel they cannot show fear or weakness to you. "I know how you feel" — you don't, not exactly. What helps more: "I'm here." "What do you need today?" "You don't have to be strong with me." "I'm not going anywhere." Sitting in silence together. Watching a favorite film. Doing ordinary things together that have nothing to do with cancer. Support for yourself is not optional during cancer caregiving. The Caregiver Action Network (caregiveraction.org), the American Cancer Society's caregiver support line (1-800-227-2345), and cancer-specific caregiver support groups — many of which now meet online — provide the irreplaceable experience of being with people who understand from the inside what this is like. Shingles — Painful, Common, and Vaccine-Preventable Shingles (herpes zoster) is caused by the reactivation of the chickenpox virus, which lies dormant in nerve tissue after a person recovers from chickenpox. It affects roughly one in three Americans over a lifetime, with risk increasing significantly with age and with any condition or medication that suppresses the immune system. About half of all shingles cases occur in adults over 60. Shingles typically presents as a painful rash — often a band or strip on one side of the body or face — accompanied by burning, shooting pain, tingling, or extreme sensitivity to touch. The pain frequently precedes the rash by several days, which can make early diagnosis difficult. The rash blisters, crusts over, and resolves over two to four weeks. The pain, however, can be far more persistent. Postherpetic neuralgia — the most serious complication: In roughly 10–18% of shingles cases — with higher rates in older adults — the pain continues long after the rash has healed, sometimes for months or years. This condition, called postherpetic neuralgia, can be severe and debilitating. It is the most common complication of shingles and one of the most difficult pain syndromes to treat. In older adults, it significantly affects quality of life, sleep, and mood. Eye involvement: When shingles affects the area around the eye — a condition called herpes zoster ophthalmicus — it can cause vision problems and requires immediate ophthalmologic evaluation. Any shingles rash near the eye warrants urgent medical attention. Treatment: Antiviral medications — acyclovir, valacyclovir, or famciclovir — are most effective when started within 72 hours of rash onset, ideally sooner. Early treatment reduces the severity of the rash and the duration of pain, and reduces the risk of postherpetic neuralgia. If your parent develops a suspicious rash with pain, contact their physician the same day. The Shingrix vaccine (recombinant zoster vaccine) is more than 90% effective at preventing shingles and is recommended for all adults 50 and older, including those who have already had shingles. It is given as two doses, two to six months apart. If your parent has not received Shingrix, ask their physician at the next visit. Medicare Part D covers it. UTI and Sudden Confusion — The Most Misunderstood Emergency This section covers something that almost no family knows before they need to know it — and that causes enormous unnecessary panic, delayed treatment, and misdiagnosis every year. If your parent suddenly becomes confused, agitated, disoriented, or seems to be hallucinating — and this is new and rapid in onset — check for a urinary tract infection before assuming anything else. In older adults, particularly older women, a UTI is one of the most common causes of sudden dramatic cognitive change. Why UTIs Present So Differently in Older Adults In younger adults, a urinary tract infection announces itself clearly: burning with urination, frequent urination, pelvic discomfort. In older adults — particularly women over 70 — these classic symptoms are often absent or minimal. Instead, a UTI may present primarily or exclusively as a sudden change in mental status. A parent who was oriented, functional, and themselves yesterday may suddenly appear confused about where they are, agitated or combative, disoriented to time and place, or even hallucinatory. The change can happen in hours. Families who do not know this connection — and most do not — assume their parent has had a stroke, entered sudden severe dementia, or is having a psychiatric episode. They rush to the emergency room terrified. The cause is often a UTI, and it is frequently completely reversible with a course of antibiotics. Why This Happens Several factors make older adults — particularly women — vulnerable to UTIs with atypical presentation. Reduced immune response means the body is less able to contain the infection locally, allowing it to affect the brain and nervous system more broadly. Reduced kidney function means the infection can have broader systemic effects. Dehydration — very common in older adults, who often have a diminished sense of thirst — concentrates the urine and creates conditions favorable to bacterial growth. Thinning of urinary tract tissues after menopause increases vulnerability to infection. The inflammation connection: Researchers believe that the systemic inflammatory response to a UTI affects neurotransmitter function in the brain — particularly in people who already have some degree of cognitive fragility — producing the sudden confusion. This is why the effect can be so dramatic and why it resolves, in most cases, once the infection is treated. What to Do Do not wait. Sudden confusion in an older adult is always worth evaluating promptly. If your parent cannot be seen by their primary physician within a few hours, go to urgent care or the emergency room. Request a urinalysis and urine culture. Tell the provider: my parent has had a sudden change in mental status and I want a UTI ruled out. Bring a urine sample if possible. Many urgent care centers can test a urine sample on the spot. If you can collect a sample before leaving home, do so. Know your parent's baseline. The most important information you can provide to any healthcare provider is an accurate description of your parent's normal cognitive function. "She is usually sharp and oriented" tells the provider something critical. If possible, keep a brief written note of your parent's baseline — what they can normally do and what they normally know — to bring to any medical encounter. Expect confusion during treatment. Even after antibiotics are started, the confusion may persist for several days before clearing. This is normal. The infection itself is treated relatively quickly; the brain's recovery from the inflammatory response takes longer. Do not conclude that treatment is not working if your parent is still confused on day two. Prevent recurrence. UTIs in older adults tend to recur. Discuss prevention strategies with the primary physician: adequate hydration (aiming for pale yellow urine), proper hygiene, regular toileting, evaluation of whether any current medications contribute to urinary retention, and in some cases prophylactic low-dose antibiotics or vaginal estrogen therapy for postmenopausal women. Cranberry products have mixed evidence but are low-risk and some physicians recommend them. Know when it is not a UTI. Not every sudden confusion in an older adult is a UTI. Stroke, medication toxicity, severe dehydration, low blood sugar, and other conditions can also present this way. A proper medical evaluation will rule these out. The point is not to diagnose at home — it is to know that UTI belongs on the list and to make sure it is checked. The single most useful thing in this section: if your parent suddenly seems like a different person — confused, agitated, disoriented, hallucinatory — and this is new, call their doctor or go to urgent care, mention the possibility of a UTI, and ask for a urinalysis. You may save yourself days of terror and your parent days of untreated suffering. COVID-19 and Long COVID — The Ongoing Caregiving Reality COVID-19 did not end. For older adults and their families, it remains a significant and ongoing caregiving concern — not primarily because of acute infection risk, which has become more manageable with vaccination, but because of its longer-term effects on aging adults who were infected, and because of the lasting damage that pandemic isolation caused to a generation of older people. Why COVID Hits Older Adults Harder Age is the single strongest risk factor for severe COVID-19. The immune system's ability to respond to new pathogens diminishes with age — a process called immunosenescence — making older adults both more vulnerable to severe infection and less responsive to vaccines (though vaccination still provides meaningful protection). Preexisting conditions that are common in older adults — heart disease, diabetes, chronic lung disease, obesity — dramatically increase the risk of severe illness, hospitalization, and death. For caregivers of aging parents, COVID remains relevant in 2026 for several specific reasons: ongoing vaccination decisions, Long COVID management, the cognitive effects of infection, and the lasting harm of pandemic isolation. Vaccination — An Ongoing Decision Updated boosters: COVID vaccines are updated regularly to address circulating variants, similar to the annual flu vaccine. For older adults with immune compromise or multiple underlying conditions, staying current with updated boosters is one of the most effective protective measures available. Have this conversation with your parent's physician annually. Co-administration with other vaccines: Older adults are also advised to receive flu vaccines, RSV vaccines, and pneumonia vaccines. Ask the physician which vaccines are recommended, whether any interactions exist, and whether co-administration on the same day is appropriate for your parent's specific situation. Antiviral treatment: If your parent contracts COVID, antiviral medications — particularly Paxlovid — are available for high-risk individuals and must be started within the first five days of symptom onset. Know in advance whether your parent is a candidate, whether there are any medication interactions with their current prescriptions (Paxlovid has several significant interactions), and how to access the medication quickly if needed. Have this conversation before it becomes urgent. Long COVID — What Caregivers Need to Know Long COVID — also called post-acute sequelae of COVID-19 (PASC) — refers to symptoms that persist or develop weeks to months after an acute COVID infection, in people who may have had mild or even asymptomatic initial illness. It affects an estimated 10–30% of people who contract COVID, with higher rates in older adults and those with underlying conditions. Fatigue: Post-exertional malaise — profound exhaustion triggered by physical or mental activity that previously would have been manageable — is the hallmark symptom of Long COVID. It is not ordinary tiredness. It does not improve with rest the way ordinary tiredness does. It can be severely disabling. If your parent was infected with COVID and seems dramatically more fatigued than before, Long COVID deserves consideration. Cognitive effects — 'Brain fog': Difficulty with memory, concentration, word-finding, and processing speed is reported by a significant proportion of Long COVID patients. In older adults who already have some degree of cognitive aging, Long COVID cognitive effects can tip someone from manageable to significantly impaired, and can be mistaken for dementia onset or acceleration. If your parent's cognitive function changed noticeably after a COVID infection, raise this with their physician. This is a recognized and treatable syndrome, not simply aging. COVID and dementia acceleration: Research published since the pandemic began consistently shows that COVID infection — even mild infection — is associated with accelerated cognitive decline in people with early Alzheimer's or other dementias. The inflammatory response to infection appears to worsen the underlying neurodegenerative process. If your parent has early dementia, protecting them from COVID infection through vaccination, masking in high-risk settings, and prompt antiviral treatment if infected is particularly important. Cardiovascular effects: COVID infection increases the risk of heart attack, stroke, and new-onset heart arrhythmias for months after infection, even in people who had mild illness. For older adults with existing cardiovascular disease, this elevated risk is meaningful. Discuss with the physician whether any additional monitoring is warranted after a COVID infection. Getting help for Long COVID: Long COVID clinics have been established at many major academic medical centers. If your parent's symptoms are significantly affecting their quality of life, ask for a referral. The National Institutes of Health RECOVER program (recovercovid.org) also provides resources and information about ongoing research and care options. The Lasting Harm of Pandemic Isolation One of the most significant and least-discussed consequences of the COVID pandemic for older adults is what sustained isolation did — and continues to do — to their physical and mental health. Older adults who were isolated during the pandemic years — particularly those in assisted living or nursing facilities who could not see family members for months — experienced measurable harm that persists years later. Accelerated cognitive decline: Social engagement is one of the strongest protective factors against dementia progression. The loss of in-person social connection during the pandemic is associated with accelerated cognitive decline in multiple studies. Depression and anxiety: Rates of depression and anxiety in older adults spiked dramatically during the pandemic and have not fully returned to pre-pandemic levels. If your parent seems more withdrawn, more anxious, or less engaged than before the pandemic, this is not simply aging — it is a real and treatable consequence of what they experienced. Physical deconditioning: Reduced activity during lockdowns caused physical deconditioning in older adults who lost access to their normal routines — walking groups, fitness classes, church, volunteer work. The resulting loss of strength, balance, and stamina increases fall risk and reduces functional independence. Physical therapy and gradual return to activity can reverse much of this. What helps now: Deliberate rebuilding of social connection is among the most important things you can do for a parent affected by pandemic isolation. Reconnecting with faith communities, senior centers, volunteer programs, and in-person groups is not just pleasant — it is therapeutic. If your parent resists, understand that social anxiety can develop during prolonged isolation and may require gentle, gradual re-engagement rather than immediate full participation. Sexually Transmitted Infections — The Topic Nobody Brings Up Sexually transmitted infections in older adults are more common than most families — and most physicians — recognize, and they are rising. Between 2000 and 2020, STI rates among adults 65 and older increased substantially, with syphilis, gonorrhea, chlamydia, and HIV all showing significant increases in this age group. For adult children in a caregiving role, this is not comfortable territory. It is also unavoidable territory if you are paying attention to your parent's whole health. This section is not here to make anyone uncomfortable. It is here because ignoring this topic means families are unprepared for situations that are entirely manageable when understood — and potentially serious when missed. Why rates are rising in older adults: Several factors converge. Older adults grew up before comprehensive sexual health education and often carry assumptions — that STIs are a young person's problem, that they are immune from risk — that simply are not accurate. Many older adults are newly single after divorce or the death of a spouse, and are sexually active in ways their adult children may not know about or may prefer not to think about. Condom use is low among older adults because pregnancy prevention is no longer a concern, and the protective habit was never established. Erectile dysfunction medications have extended the sexual lives of older men. And physicians rarely ask older patients directly about sexual activity or screen for STIs routinely. The most common STIs in older adults: Herpes simplex (HSV) is extremely prevalent — an estimated two-thirds of adults carry oral herpes and roughly one in six carry genital herpes, often without knowing it. Syphilis, gonorrhea, and chlamydia have all increased significantly. HIV is diagnosed in adults over 50 at rates that often surprise people — this population is less likely to be tested, more likely to be diagnosed late, and more likely to have HIV misattributed to other conditions. HIV in older adults is frequently diagnosed late because physicians are less likely to test for it in this age group, and because symptoms — fatigue, weight loss, cognitive changes — overlap with many other conditions common in aging. If your parent has risk factors for HIV exposure, testing is appropriate regardless of age. What symptoms can look like in older adults: STIs in older adults frequently present atypically or asymptomatically. Syphilis can mimic dementia in its later stages — the neurological effects of tertiary syphilis can produce cognitive decline, personality changes, and psychiatric symptoms that are genuinely mistaken for Alzheimer's disease. Any older adult with unexplained cognitive changes should have a syphilis test as part of the workup. Herpes outbreaks may be milder and less recognizable. Gonorrhea and chlamydia may cause urinary symptoms that are attributed to UTIs or prostate issues without the underlying STI being identified. The cognitive capacity dimension: For caregivers of parents with dementia or significant cognitive impairment, sexual activity raises important and difficult questions about consent and vulnerability. A person with advanced dementia may not have the capacity to consent to sexual activity — with a partner, a fellow resident in a care facility, or a caregiver. This is a form of elder sexual abuse that is underreported and poorly understood. If you are concerned that your parent is being sexually exploited or is engaging in sexual behavior without capacity to consent, speak with the facility administrator, the social worker, and if necessary the physician and adult protective services. This is an area where caregivers need to be advocates. Conversation with the physician: Routine STI screening is not standard for older adults unless risk factors are identified — and physicians often do not ask. If your parent is sexually active, particularly with a new or multiple partners, raise the topic with the physician directly. Request appropriate screening. This conversation may be awkward. It is less awkward than a missed diagnosis. For caregivers of parents who are newly dating: A parent who is widowed or divorced and dating again is in a situation that can feel strange to adult children — simultaneously encouraging and concerning. The most useful thing you can do is make sure they have accurate information about sexual health risk, access to protection, and a physician who knows they are sexually active. You do not have to manage their choices. You do have a role in making sure they have the information to make them safely. Treatment: All of the most common bacterial STIs — syphilis, gonorrhea, chlamydia — are fully treatable with antibiotics when caught. HIV, while not curable, is highly manageable with antiretroviral therapy, and people who begin treatment promptly can live for decades with a normal or near-normal life expectancy. Herpes is manageable with antiviral suppressive therapy. The key in every case is identification and treatment — which requires testing, which requires the topic being raised. David Miller and His Mother Martha David Miller was a successful businessman. His mother Martha was 78 when she was diagnosed with Alzheimer’s disease. David had grown up watching his mother manage everything with apparent ease — the household, the finances, the social calendar, three children and an aging parent of her own. She had always been the person others turned to. The Alzheimer’s diagnosis arrived not as a single revelation but as the end of a long period of confusion. There had been the afternoon Martha called David three times in two hours with the same question. The week she couldn’t find her own address book, which had been in the same drawer for thirty years. The Sunday dinner when she called David by his father’s name and didn’t seem to notice. The diagnosis clarified some things and made others harder. David took a leave of absence from work. He restructured his mother’s care entirely, hiring a daytime aide and setting up a monitoring system in her home. He learned about dementia caregiving from a support group the hospital connected him to. What surprised him most, he said later, was the support group itself — the relief of sitting in a room with people who understood not just the logistics but the specific emotional texture of it. “I had been telling everyone I was managing,” he said. “In that room, for the first time, I didn’t have to manage. I could just say what it was actually like.” The support group also taught him something practical he hadn’t known: that Martha’s frequent agitation in the late afternoon — what the group called sundowning — could be managed with routine and light and redirection, rather than with attempts at correction or reassurance. The afternoons became easier. Not easy. But easier. David’s experience illustrates something worth stating directly: the practical and the emotional dimensions of caregiving are not separate things. Learning better caregiving strategies reduced his exhaustion. Reduced exhaustion made space for emotional processing. Emotional processing reduced his guilt and resentment. And reduced guilt and resentment made him a more patient, more present caregiver. These things feed each other. You cannot tend only one of them.
