Dementia and Alzheimer's Care: Sundowning, Stages, Options and Costs

What is the difference between dementia and Alzheimer's?

Dementia is an umbrella term, not a diagnosis. It describes a decline in memory, reasoning, language or judgement severe enough to interfere with daily life. Alzheimer's disease is the specific illness behind roughly two-thirds of those cases — so every person with Alzheimer's has dementia, but not every person with dementia has Alzheimer's.

The distinction is practical rather than academic, because the other causes behave differently. Vascular dementia often progresses in visible steps after strokes. Lewy body dementia brings visual hallucinations, sleep disturbance and marked day-to-day fluctuation, and carries a dangerous sensitivity to certain antipsychotic medicines. Frontotemporal dementia usually starts with personality and language change rather than memory loss, frequently before age 65.

Some conditions that look like dementia are reversible: thyroid disease, B12 deficiency, depression, delirium from an infection, dehydration, or interactions between prescriptions. A sudden change over days rather than months is a medical emergency, not a stage of dementia, and should be assessed the same week.

• Alzheimer's disease — gradual short-term memory loss first; the most common cause.
• Vascular dementia — stepwise decline tied to strokes and small-vessel disease.
• Lewy body dementia — hallucinations, fluctuation, movement symptoms, antipsychotic sensitivity.
• Frontotemporal dementia — early personality, behaviour or language change; younger onset.
• Mixed dementia — more than one process at once; common in people over 80.

The stages of dementia and what changes at each one

Clinicians often use a seven-stage scale, but families plan better with three: early, middle and late. What matters is not the label but which supports each stage requires and what the next stage will cost.

In the early stage the person still lives largely independently. Repeated questions, missed bills, misplaced items and trouble finding words appear first. This is the window for legal and financial planning, because capacity to sign a power of attorney still exists.

The middle stage is usually the longest, often several years, and is the point at which most families run out of capacity to cope alone. Help is needed with bathing, dressing and medications; wandering, sundowning and resistance to care emerge; the person may no longer recognise dates, places, or occasionally people. Care hours climb steeply here.

In the late stage, mobility, swallowing and speech decline, incontinence is constant, and the person becomes fully dependent. Care shifts toward comfort, skin integrity, nutrition and infection prevention — the point at which palliative and hospice teams add the most value.

• Early — supervision, reminders, driving assessment, legal and financial planning.
• Middle — daily hands-on help, secured environment, structured routine, respite for the caregiver.
• Late — total assistance, mobility and swallowing support, comfort-focused care.

What is sundowning, and how do you manage it?

Sundowning is a pattern of increased confusion, agitation, restlessness, pacing, suspicion or distress that appears in the late afternoon and evening in people with dementia. It is not a separate disease and not deliberate behaviour: it reflects a damaged internal body clock combined with fatigue, low light, hunger, pain and an over-stimulating end to the day.

Before treating sundowning as a behaviour, rule out a cause. A urinary tract infection, constipation, untreated pain, a new medication, poor sleep, hearing loss or a change in surroundings will each produce late-day agitation, and each is fixable. Sudden onset over days points to delirium and warrants same-week medical review.

Non-drug measures work better than medication for most people and carry none of the risk. The goal is a predictable, well-lit, low-demand evening: consistent timing, bright light earlier in the day, the biggest meal at midday, caffeine and alcohol removed after lunch, television news and crowded rooms avoided after dark, and closed curtains so reflections in dark windows do not become frightening.

When agitation is severe, dangerous or unresponsive, involve the prescriber rather than improvising. Antipsychotics carry a boxed warning for increased mortality in older adults with dementia and are especially hazardous in Lewy body dementia. They are a last resort at the lowest effective dose with a planned review date, not a routine answer.

• Keep wake, meal, activity and bedtime at the same clock time every day.
• Maximise bright light in the morning; turn lamps on before dusk to remove shadows.
• Serve the largest meal at midday; offer a light snack in the evening.
• Stop caffeine and alcohol after lunch; limit long daytime naps to early afternoon.
• Plan demanding tasks such as bathing and appointments for the morning.
• Reduce evening noise, visitors and screen time; use familiar music instead.
• Do not argue or correct — validate the feeling, then redirect to a simple activity.
• Address safety: door alarms, secured exits, a night light on the route to the bathroom.

Alzheimer's care options and what they cost

Care for Alzheimer's and other dementias is delivered in four main settings, and most families move through more than one. In-home care preserves familiar surroundings and is billed hourly, so it is the cheapest option at a few hours a day and the most expensive once supervision must be constant. Adult day programmes provide structured daytime activity and respite at a fraction of residential cost. Memory care — secured assisted living with dementia-trained staffing — averages about $6,935 a month nationally. Skilled nursing becomes necessary when medical complexity or immobility exceeds what memory care is licensed to handle.

The usual trigger for a move is not memory loss itself but safety: wandering out of the house, a fall, a stove left on, aggression toward the caregiver, incontinence beyond what one person can manage, or a caregiver whose own health is failing. Deciding in advance which of these will be the line makes the decision far less painful when it arrives.

Memory care runs roughly 20 to 30 percent above standard assisted living in the same market, reflecting secured doors, higher staffing ratios and dementia training. Medicare does not pay for room and board in any of these settings; Medicaid may cover nursing home care and, in many states, memory care through a home and community-based services waiver with a waiting list.

• In-home care — hourly; flexible early on, costliest once supervision is 24/7.
• Adult day programmes — structured daytime care plus caregiver respite at low cost.
• Memory care — secured, dementia-trained residential care; the most common destination.
• Skilled nursing — for medical complexity, immobility or late-stage needs.
• Respite stays — short residential stays that let a family caregiver recover.

Palliative care, hospice and end-of-life care

Palliative care means specialist care focused on relieving symptoms, pain and stress from a serious illness. Its most misunderstood feature is that it is not limited to the end of life: palliative care can begin at diagnosis and run alongside treatment intended to slow the disease, at any age and any stage.

Hospice is palliative care for the final phase. In the United States, the Medicare hospice benefit applies when a physician certifies a prognosis of six months or less if the illness follows its expected course, and treatment shifts from cure to comfort. It covers the hospice team, medications related to the terminal diagnosis, equipment and supplies, and it can be delivered at home, in a nursing home or in a memory care community.

Dementia complicates the timing, because the illness declines over years rather than weeks. Recognised hospice triggers include the inability to walk or dress without help, minimal intelligible speech, recurrent aspiration pneumonia or urinary infections, pressure ulcers and sustained weight loss. Families routinely enrol later than they would choose in hindsight; asking the physician directly whether hospice criteria are met costs nothing.

• Palliative care — symptom relief at any stage, alongside ongoing treatment.
• Hospice — comfort-focused care with a six-month prognosis; a Medicare benefit.
• Advance directives — record treatment wishes while capacity remains.
• Comfort feeding — hand feeding for pleasure rather than feeding tubes in late dementia.

Support for the caregiver

Dementia caregiving is measured in years, and the caregiver's health is part of the care plan, not a side issue. Sleep loss, depression and lost income are the norm rather than the exception, and a caregiver who collapses forces exactly the emergency placement the family was trying to avoid.

Practical relief exists and is under-used: adult day programmes, in-home respite hours, short residential respite stays, Area Agency on Aging caseworkers, Alzheimer's Association support groups and a 24/7 helpline, and — for eligible veterans — VA respite and Aid and Attendance benefits.
