Guide
Stages of Alzheimer's and what type of care fits each one
Updated October 15, 2026 · Reviewed against official sources
This guide doesn't diagnose your loved one or tell you what stage they're in: that's the medical team's job. It simply lays out the care options so your family can plan calmly.
Before thinking about stages: ask for an evaluation
Not all forgetfulness is Alzheimer's. MedlinePlus, from the National Institutes of Health (NIH), explains that there's a condition called mild cognitive impairment: memory problems that are somewhat worse than those of other people the same age, but that don't get in the way of daily life and don't always lead to Alzheimer's. Also, during the evaluation, the doctor looks for other causes of confusion, such as thyroid problems, low vitamin levels, depression or the side effects of a medication.
Where to start:
- Medicare yearly "Wellness" visit: once every 12 months, at no cost if the provider accepts Medicare assignment. It includes a cognitive assessment to look for signs of dementia.
- Cognitive assessment and care plan visit: if the doctor suspects a problem, Part B covers a separate visit to take a thorough look at memory and thinking, confirm a diagnosis and make a care plan. After the Part B deductible, you pay 20% of the approved amount. A family member can come along.
- Alzheimer's Disease Research Centers: the National Institute on Aging (NIA) funds centers at universities and hospitals across the country that offer diagnosis, research studies and support groups. The NIA's information center (ADEAR) provides guidance in English and Spanish: 800-438-4380, Monday through Friday.

Mild (early) stage
What usually happens. According to the NIA and MedlinePlus, tasks that used to be easy, like keeping track of bills or learning something new, become harder. The person may repeat questions, misplace things, get lost on a familiar route or have mood changes. Many people are diagnosed in this stage and still do much of their daily life on their own.
Care that often helps:
- Staying at home with support: routines, medication reminders, help with paying bills and someone to go along to appointments.
- A social adult day center, to stay active and have company. See our guide to adult day centers.
- Planning while your loved one can still make decisions: this is the best time for a power of attorney, a health care proxy and advance directives. Read power of attorney and advance directives.
- Learning about Medicaid early: many in-home programs have waiting lists. See Medicaid home care programs.
Ask your loved one what matters to them: their home, their church, their food, their language. That guides everything that comes next.
Moderate (middle) stage
What usually happens. According to the NIA, the person may have trouble recognizing family and friends and doing tasks with several steps, like getting dressed. MedlinePlus mentions changes in sleep, trouble cooking or driving, less ability to recognize danger and, sometimes, agitation or hallucinations.
Care that often helps:
- More supervision at home: a caregiver by the hour or in shifts. Look for home care agencies and estimate the cost with the home care calculator.
- Adult day health care, with nursing and activities designed for people with memory problems. Look for options in our adult day center directory.
- Respite care for the family: a few hours or a few days of rest. Read respite care.
- A safer home: see adapting the home.
- Medicare's GUIDE model: a voluntary CMS program for people with dementia and their caregivers, which started on July 1, 2024, and runs for 8 years. It offers a care coordinator, a 24/7 support line, caregiver training and up to $2,500 a year in respite care. It's for people who have Medicare Parts A and B as their main insurance, who aren't in Medicare Advantage, PACE or hospice, and who don't live in a nursing home long term. Ask the doctor whether they work with a GUIDE team.
When your loved one can no longer stay alone, wanders off and gets lost, or the person caring for them is worn out, it may be time for assisted living with memory care or a small residential care home with dementia experience. Read memory care and, for the move, how to prepare a loved one with dementia.
Advanced (severe) stage
What usually happens. MedlinePlus explains that the person may stop recognizing their family, stop understanding what's said to them and no longer be able to eat, dress or bathe without help. Problems with swallowing and with bladder or bowel control may appear. The NIA adds that the person can no longer communicate with words and depends completely on others, and that near the end, they spend most of their time in bed.
Care that often helps:
- Total help, day and night, at home with a lot of support or in a nursing home, often in a memory care unit. Compare places in the senior living directory and bring the visit checklist.
- Palliative care to ease discomfort at any point in the illness.
- Hospice, when the doctor certifies a prognosis of 6 months or less. It's provided at home or in the care facility, and Medicare covers it. Read hospice and palliative care and look for providers in our hospice directory.
Connection still matters: holding their hand, playing their music, speaking to them in their language.
Summary by stage
| Stage | What the person often needs | Common options | What to get ready |
|---|---|---|---|
| Mild | Reminders, help with money, companionship | Home with support, social adult day center | Legal papers, a conversation about their wishes, Medicaid information |
| Moderate | Daily supervision and help with dressing, eating or bathing | In-home caregiver, adult day health care, respite care, memory care | Respite plan, home safety, visits to care facilities |
| Advanced | Total help 24 hours a day | Nursing home, intensive care at home, hospice | Up-to-date advance directives, a conversation with the hospice team |
Our Katz and Lawton scales help you sort out how much help your loved one needs; they're a guide, not a diagnosis.
How to pay for care
Medicare pays for doctor visits and hospice, but not for daily care or memory care. Medicaid can pay for in-home services, adult day care and nursing home care if your loved one qualifies. The VA, PACE or long-term care insurance can also help. See how to pay for long-term care.
Take care of the caregiver too
If your loved one's Medicare provider considers it part of the treatment, Part B can cover caregiver training services, even without your loved one present; you pay 20% after the deductible. The Alzheimer's Association, a nonprofit organization, has a free 24/7 helpline with help in Spanish: 800-272-3900. For local services, call the Eldercare Locator: 1-800-677-1116, Monday through Friday from 9 a.m. to 8 p.m. Eastern time; if you prefer Spanish, ask for it when you call. And if you feel you're at your limit, read about caregiver burnout.
Frequently asked questions
How long does each stage last?
There's no set timeline: each person progresses at their own pace, and the stages overlap. Your loved one's doctor is the best person to guide you.
How do I know what stage my loved one is in?
Ask at the cognitive assessment visit or at follow-up appointments, and bring written examples of what's happening at home.
Is hospice only for people with cancer?
No. Medicare covers hospice for any terminal illness when the doctor certifies a prognosis of 6 months or less, and that can include advanced dementia.
Do I have to wait until the advanced stage to look for a care facility?
No. Many families visit places during the mild or moderate stage so they can decide calmly. You can search with the guided search or look near you.
