Dementia Care at Home: What the Job Is at Each Stage

Caring for someone with dementia at home is three different jobs in sequence: supervising, then physically caring, then nursing. What makes it distinctive is not the number of hours but the difficulty of them, and the published evidence supports that framing rather than the hours claim you will see repeated everywhere. The Alzheimer’s Association compares difficulty, not duration: compared with caregivers of people without dementia, more caregivers of those with dementia indicate substantial emotional, financial and physical difficulties¹.

Some scale first. In 2021, 57 million people were living with dementia worldwide, over 60 percent of them in low and middle income countries, with nearly 10 million new cases every year and Alzheimer’s disease contributing to 60 to 70 percent of cases (WHO, Dementia fact sheet, page dated 3 July 2026)². In the United States, nearly 13 million people provide unpaid care for a family member or friend with dementia, and in 2025 they provided more than 19 billion hours of care, valued at more than $446 billion (Alzheimer’s Association, 2026 Alzheimer’s Disease Facts and Figures)¹. Around 70 percent of the lifetime cost of dementia care is borne by families¹.

A note on what I can and cannot tell you here. My mother does not have dementia. What I have is four years in the same waiting rooms, the same carers’ group and the same forum threads as people who do, and enough sense to write this page from the sources and from other carers’ words rather than pretending to an experience I have not had. Where a first-hand beat belongs to someone else, I have said so. This article sits under caring for a parent at home.

What is the carer actually doing at each stage?

The work changes character roughly three times, and each change catches people out because the previous set of skills stops being the relevant ones.

Early: supervision, prompting and protecting the routine. You are a prompt and a safety net rather than a pair of hands. Appointments, finances, the medication round, keeping familiar routines intact because routine does much of the cognitive work that memory used to. This is also the only stage in which legal and financial planning is possible, which makes it the single most important window in the whole course: see power of attorney and decisions. Alzheimer’s Disease International reports that people who had engaged in tailored individual cognitive rehabilitation had lower levels of disability and remained in their own homes for six months longer than average, which is a reason to ask about rehabilitation early rather than assuming nothing can be done³.

Middle: hands-on care and behaviour change. Washing, dressing, continence, meals, and the part nobody warns you about, which is that communication becomes a skill you have to learn rather than something you already have. Repetition, refusal, agitation in the late afternoon and disturbed nights all cluster here. This site covers them separately in repeated questions and what to say, sundowning and difficult nights and wandering and keeping someone safe. The practical care is in continence and keeping dignity and moving someone safely.

Late: physical care and communication loss. Mobility goes, swallowing becomes difficult, weight falls, skin becomes vulnerable, and speech may go almost entirely. Malnutrition risk is high in this group generally: 56 percent of adults screened in their own homes across UK health and care settings were at risk of disease-related malnutrition, on a voluntary survey of people screened rather than a population estimate (BAPEN, 2022 UK Survey)⁴. See eating, drinking and weight loss and preventing pressure sores. When they do not know you is about the moment most carers dread, which arrives for some people and not others.

Globally, informal carers of people with dementia provide on average 5 hours of care and supervision per day, and women provide 70 percent of those care hours (WHO, data year 2019)².

Why is a sudden change almost never the dementia?

Because dementia is a gradual decline over months and years, and anything that arrives over hours or a day or two has a different cause. This is the single most useful thing on this page.

New confusion, or confusion that is markedly worse and comes and goes through the day, is usually delirium. It is common, it is frequently missed, and it is often reversible. NICE describes delirium as a clinical syndrome characterised by disturbed consciousness, cognitive function or perception, with an acute onset and fluctuating course, usually developing over 1 to 2 days, and states plainly that “it can be prevented and treated if dealt with urgently”⁵. It also acknowledges the difficulty: “It can be difficult to distinguish between delirium and dementia and some people may have both conditions.”⁵

The instruction that follows is the one to remember, and it is verbatim: “If there is difficulty distinguishing between the diagnoses of delirium, dementia or delirium superimposed on dementia, manage the delirium first.”⁵ Nobody expects you to make the diagnosis. What you are expected to do is notice the change and ring. Be especially alert to the quiet form, since NICE tells clinicians to be “particularly vigilant for changes that may indicate hypoactive delirium, which are often missed, such as withdrawal, slow responses, reduced mobility and movement, worsened concentration and reduced appetite”⁵.

Delirium or dementia sets out the distinction in full, and spotting when someone is getting worse is the general method.

What are the real safety risks at home?

Falls and seizures, both raised well above the background rate. Alzheimer’s Disease International reports that “seizures are up to seven times more common in people with dementia compared with peers of the same age, while falls that cause injury are two to three times more common”³. That sits on top of an already high baseline: around a third of people aged 65 and over, and around a half of people aged 80 and over, fall at least once a year, and the one-year mortality rate after a hip fracture is 31 percent (NICE guideline NG249, published April 2025)⁶.

The response is an assessment rather than a rearrangement. Ask for an occupational therapy assessment of the home, ask for a falls assessment after any fall, and treat the second fall as urgent rather than as bad luck. Falls at home covers the first minutes after one and what to ask for afterwards. Adaptations and technology at home covers what equipment and sensors realistically do, including their limits, which matter more here than anywhere else on this site.

Walking and going out are a separate problem with an ethical dimension, because restricting someone’s movement is a decision with legal limits. Wandering and keeping someone safe covers the risk assessment, doors and locks, identification, and what to do if somebody goes missing.

What about medication?

The rule on this site is absolute: no page here gives a dose, a dose change, or an instruction to give or withhold anything. That belongs to the prescriber and the pharmacist, who know the whole list.

What you can do is ask for a review. NICE guideline NG5 recommends considering a structured medication review for people taking multiple medicines, people with long-term conditions and older people, taking into account the person’s and carers’ views and concerns, all prescribed, over-the-counter and complementary medicines and what they are for, safety, effectiveness and appropriateness, risk factors for adverse drug reactions, and the monitoring needed⁷. In dementia the list tends to accumulate quietly over years, and a review is the mechanism for looking at all of it at once rather than one item at a time. A new or changed medicine is also one of the first things a clinician looks for when somebody with dementia becomes suddenly confused, which is common enough that 10 to 50 percent of people having surgery develop delirium and about 20 to 30 percent of people on medical wards have it⁵. Managing someone else’s medication covers the round itself, refusals, missed doses and how to request the review.

What does this do to the carer, and what helps?

Dementia caring carries the highest measured psychological cost of any common caring role. The Alzheimer’s Association reports, verbatim, that “the prevalence of depression is higher among dementia caregivers (30% to 40% as reported in multiple studies) than other caregivers, such as those who provide help to individuals with schizophrenia (20%) or stroke (19%)”, with anxiety among dementia caregivers at 40 percent or more¹. That 30 to 40 percent is a range across multiple studies rather than one survey estimate, so read it as a literature range. US dementia caregivers were also more likely to report depression, 32.5 percent, or anxiety, 26 percent, than those in Japan or five European countries¹.

NICE recognises the risk directly: “Be aware that carers of people living with dementia are at an increased risk of depression.”⁸

What has the best support is training rather than sympathy. NG97 recommends offering carers a psychoeducation and skills training intervention covering education about dementia and its progression, personalised strategies and skill-building, understanding and responding to behaviour change, adapting communication styles, advice on the carer’s own physical and mental health, planning enjoyable and meaningful activities, information about relevant services, and planning for the future, and adds that carer interventions “are likely to be most effective when provided as group sessions”⁸. Respite appears exactly once in the whole guideline, as a recommendation to “advise carers about their right to carer assessment, and assessment for respite care and other support”⁸, and NICE’s separate carers guideline concedes “a lack of evidence on effectiveness or cost effectiveness to support a recommendation about the circumstances in which carers’ breaks should or shouldn’t be offered”⁹. Arrange the break anyway. Just do not treat its failure to fix things as your failure. Carer burnout and your own health sets out the full evidence, and getting help in covers how to trigger each kind of support.

Planning ahead, including for the part nobody wants to plan

Two facts belong together here. Alzheimer’s Disease International reports that “75% of WHO Member States still have no national dementia plan”, so the amount of organised support available varies enormously by where you live³. And most people with dementia do not die at home: in England in 2024, 64.1 percent of dementia deaths occurred in a care home, against 28.1 percent of all deaths occurring at home and 42.3 percent in hospital (Office for Health Improvement and Disparities, experimental statistics)¹⁰.

That figure is not a prediction about your household and it is not permission to stop. It is a reason to have the conversation early, while the person can still take part in it, about what they would want and what they would not. Write the answers down. Keeping a care file is where they live, and palliative care at home explains what palliative care actually is, which is not the same as end-of-life care and usually starts much earlier than families expect.

Money planning belongs in the same early window. Informal care accounts for roughly half of global dementia costs³, which is another way of saying that most of this expense lands on families. Paying for care and what you can claim covers who pays for what and what you can claim in your own right.

This is a call today, not next week

With dementia, the temptation is to read every change as the condition progressing. Resist it. Ring the same day if the person you look after:

• Is more confused than they were yesterday, or the confusion comes and goes through the day. Use the word confusion, and say what they were like last week.
• Has become withdrawn, slow, drowsy or has stopped eating, which is the quiet form of delirium and the one most often missed⁵.
• Has had a fall, even one they got up from.
• Has stopped drinking, or their urine has gone dark and scant.
• Has a new fever, new pain, or agitation that is new for them, particularly if they cannot tell you what hurts.
• Has a sudden change in continence, which is a medical sign and not a laundry problem.

Who to ring: in the United Kingdom, their GP surgery or NHS 111 out of hours. In the United States, their doctor’s office or the nurse line their plan runs. In Australia, their GP or healthdirect on 1800 022 222. In Canada, their family doctor or the provincial health line, 811 in most provinces. In Ireland, their GP or the out of hours GP service. For changed breathing, chest pain, one-sided weakness, changed speech, a first seizure, or bleeding that will not stop, use the emergency number immediately: 999 or 112 in the United Kingdom and Ireland, 911 in the United States and Canada, 000 in Australia.

Say the word delirium on the call if you think it applies. It is a word that changes the speed of the response, and it is the one carers are least likely to know they are allowed to use.
