It may be easy to brush off misplacing your dog’s leash before a walk or forgetting the rules of a card game. But when moments of forgetfulness regularly make it hard to do daily tasks, it may be a sign of more serious memory loss triggered by Alzheimer’s disease.
What is Alzheimer’s disease?
Alzheimer’s disease is the most common type of dementia, which is a condition that chips away at your memory, behavior, and ability to think. Over time, the brain shrinks from a buildup of plaque and tangles of proteins from dead nerve cells,1 making it difficult to function in day-to-day life. According to the Alzheimer's Association, 6.9 million Americans had Alzheimer’s disease in 2024, and that number could rise to 13.8 million people by 2060.2
Alzheimer's Association, 7.4 million Americans are living with clinical Alzheimer’s disease in 2026, and that number is expected to continue rising based on the growing population of adults age 65 and older.2
What are the warning signs of Alzheimer’s disease?
From having difficulty following and participating in conversations to increased irritability, there are a number of early symptoms of Alzheimer’s and other dementias. Knowing these can help you spot changes in your or a family member’s behavior, including:3
- Memory loss that disrupts daily life. One of the first symptoms of Alzheimer’s, such as easily forgetting new information, needing to constantly set reminders, or repeating questions during a conversation.
- Difficulty completing familiar tasks. Forgetting how to record a favorite TV show, or no longer remembering the way to drive to church or the grocery store.
- Trouble understanding visual images and spatial relationships. Finding it harder to read or losing your balance easily because of changes to your vision. You can no longer judge how far or close things really are from you.
- Misplacing things and losing the ability to retrace steps. Forgetting to put belongings in their usual places, making them harder to find later.
- Withdrawal from work or social activities. Skipping outings and gatherings because being unable to hold conversations makes it harder to socialize.
What is my risk for getting Alzheimer’s?
While the jury’s still out on what causes Alzheimer’s disease, experts say it’s important to be aware of any combination of these risk factors:
- Age. Age is a leading risk factor for Alzheimer’s disease. The risk of having Alzheimer’s only increases after age 65, with one in 13 people age 65 to 84 developing the disease.4
- Lifestyle. Certain habits can have a negative impact on the health of your body and brain. Being physically active, quitting smoking, and reducing alcohol use are just a few healthy habits that promote better brain health.4 The National Institute on Aging also recommends getting adequate sleep, eating healthy, and keeping your mind sharp through reading, hobbies, and socializing.
- Family history. If someone’s parent or sibling has Alzheimer’s disease, that person may be at higher risk of developing it in the future. This risk could come from a combination of a family’s lifestyle and genetics.5
- Genetics. Two types of genes determine risk for Alzheimer’s disease: Risk genes and deterministic genes. Risk genes, such as the APOE gene, increase your chance of developing Alzheimer’s. Deterministic genes are genes that, in very rare cases, strongly indicate you will develop Alzheimer’s.6 While genetic tests are available, the Alzheimer’s Association recommends discussing testing with a genetics counselor.
- Race or ethnicity. Higher rates of cardiovascular disease among Latino and Black communities may lead to an increased chance of Alzheimer’s disease and other forms of dementia.7 Older Latino adults are 1.5 times more likely than older white adults to develop these diseases, while older Black adults are twice as likely to develop them.7
How is Alzheimer’s disease diagnosed?
Health care providers use a combination of the following tests, screenings, and questions to figure out if someone has Alzheimer’s disease:8
What health care providers use to diagnose Alzheimer's
- A review of medical history. Do you have a family history of Alzheimer’s? How has your behavior or thinking changed over time? A doctor may ask these starter questions to assess someone’s risk.
- Physical exam. As a doctor checks your blood pressure, listens to your heart and other routine parts of a checkup, expect questions about your exercise, eating habits, and a timeline for when your symptoms began.
- Neurological exam. Tests of eye movement, reflexes, and speech can determine whether someone has Alzheimer’s or other brain conditions such as Parkinson’s disease.
- Cognitive, functional, and behavioral tests. Can you follow simple instructions? Can you memorize a list? A doctor who specializes in brain function may test you on these memory and cognitive tasks.
- Depression screenings. A doctor may ask about feelings of depression, including any shifts in your mood, negative thoughts, or loss of interest in activities you used to enjoy.
- Brain imaging. Brain scans such as magnetic resonance imaging, known as an MRI, can identify any brain shrinkage or blood vessel damage.
- Cerebrospinal fluid tests. Cerebrospinal fluid is inside the tissue surrounding your spinal cord and the brain. It can help a doctor find evidence of the plaque that builds up in Alzheimer’s disease. A doctor will need to insert a needle into your spine, known as a spinal tap, to collect a sample.
- Blood tests. In 2025, the U.S. Food and Drug Administration (FDA) cleared the first blood test used to diagnose Alzheimer's. This test can help detect early signs of the disease in people age 55 and older who are showing symptoms of memory loss or cognitive decline. It works by identifying amyloid plaques that are a hallmark of Alzheimer’s disease.
Getting an official diagnosis may seem scary, but early detection can give you and your family time to develop a plan of action around your future health and long-term needs.
Can Alzheimer’s be treated?
The FDA has approved multiple medications to either slow Alzheimer’s progression or manage the disease symptoms, such as loss of judgment and memory.
The most commonly prescribed drugs taken by mouth are:
- Cholinesterase inhibitors: Drugs such as donepezil (brand name Aricept ®) preserve the brain chemical acetylcholine, which connects the nerves that help your judgment, thinking, and memory.9
- Glutamate regulators: Glutamate is an acid that can destroy brain nerve cells.10 Drugs such as memantine (brand name Namenda) control glutamate levels and help you with reasoning, memory, and language skills.
The most commonly prescribed drugs taken intravenously:
The FDA has approved two anti-amyloid monoclonal antibody treatments for early-stage, symptomatic Alzheimer’s disease. These drugs are taken intravenously, or by IV, to slow the buildup of plaque in the brain found in Alzheimer’s disease:
- Leqembi® (lecanemab-irmb): Users of Leqembi must get an IV infusion once every two weeks for the first 18 months, and then may move to a maintenance regimen with less-frequent infusions. In August 2025, the FDA also approved LEQEMBI IQLIK, a weekly self-injected maintenance version of Leqembi that allows some patients to switch from IV infusions to a more convenient at-home treatment option.
- Kisunla™ (donanemab): Kisunla users must get an IV infusion once every four weeks. Unlike with Lequembi which is designed to be a long-term treatment, Kisunla infusions can often be stopped once amyloid plaques in the brain are reduced to a low, minimal level.11
These medicines don’t cure Alzheimer’s. But they can help to delay the progression of disease and slow cognitive decline.
Doctors must be part of an approved government registry to prescribe these drugs and ensure they’re covered under Medicare Part B for beneficiaries.
Each Alzheimer’s disease medicine can have different side effects, such as nausea or loss of appetite.9 Your doctor may also recommend medications that address other Alzheimer’s symptoms such as agitation, insomnia, and depression. Health care providers will recommend a treatment plan based on the stage of the disease and symptoms.
Will Medicare cover Alzheimer’s treatments?
The level of Medicare coverage depends on the Alzheimer’s drug.
Medicare Part D prescription plans are required to cover a minimum of two Alzheimer’s drugs for two types: cholinesterase inhibitors and glutamate regulators.12
Medicare covers the use of both Leqembi and Kisunla on three conditions:13
- You are enrolled in Medicare.
- You have evidence of brain plaques and a doctor’s diagnosis of mild cognitive impairment or mild Alzheimer’s disease dementia
- Your doctor is part of a CMS-approved patient registry that includes a clinical team and follow-up care
While there is still concern about whether these drugs are affordable, the Medicare spending cap can offer some relief. In 2026, out-of-pocket costs for prescription drugs are capped at $2,100 for Medicare Part D enrollees.14 There is also an option to spread out payments over the year, rather than paying for expensive drugs all at once. This is called the Medicare Prescription Payment Plan.14
How do I care for someone with Alzheimer’s?
Caring for a person with Alzheimer’s disease is a labor of love but it can take an emotional and physical toll on caregivers. If you help someone with Alzheimer’s who can no longer live safely on their own, they may benefit from memory care.
Memory care is a specialized form of long-term residential care for people with Alzheimer’s disease where the staff is trained in caring for people with dementia. Memory care facilities are secure environments where people can socialize, exercise, and get help with medication.
Alternatives to long-term memory care facilities include:15
- Skilled nursing facilities (nursing homes)
- Adult “day out” or day services programs
There are also resources to find in-home care for people with Alzheimer's for help with daily tasks such as bathing and giving medicine. NCOA’s BenefitsCheckUp and the U.S. Administration for Community Living’s Eldercare Locator are free resources to help you find a variety of services for people with dementia.
How do I pay for memory care?
Memory care can be expensive over the long run. The average U.S. cost of memory care in 2024 was $7,139 per month.16 But there are many payment options available to create a plan for your family that makes it as affordable as possible. Government assistance includes:15
Medicare
Medicare Part A coverage can help pay for someone to stay up to 100 days in a skilled nursing facility after a hospital stay, home health care for Alzheimer’s patients who cannot leave their homes, and hospice care for people with six months or less to live.
Medicare Part A will not cover room and board at these facilities:
- Assisted living facilities: These are residential communities where people have the privacy of their own room, but access to shared living spaces for socializing and help with bathing and dressing.
- Independent living communities: These can be condominium or apartment buildings, retirement communities with a mix of apartments and single-family homes, or housing for older adults with low incomes. Services offered may include meals, social activities, and transportation.
Medicare Part A also does not cover the costs of daily tasks like helping someone bathe, eat, or put their clothes on, which many people with dementia need help with. But Medicare may cover the costs of medical care, such as physical therapy, at assisted living facilities17 and independent living communities.
Medicare Part B will help pay for cognitive tests to diagnose dementia, help for caregivers who need Alzheimer’s disease action plans, and prescription drugs. Prescriptions will still be subject to a 20% copay.
There are also private insurance options through Medicare Advantage (Medicare Part C) that offer coverage Medicare Parts A and B provide, and additional insurance coverage through Medigap to cover out-of-pocket costs.
Medicaid
If you are enrolled in Medicaid or become eligible, Medicaid may cover 100% of the cost of a nursing home stay. It typically will not cover the costs of room and board at an assisted living facility or independent living community. But some state Medicaid programs do offer waivers to help you pay for room and board at assisted living facilities.
Medicaid’s Home and Community-Based Services program may also cover the costs of services at Medicaid-approved memory care facilities, such as assisted living. This program provides services to help with medication management, transportation, bathing, and dressing.
Contact your state Medicaid agency to see what your options are as coverage varies from state to state.
Veterans benefits
Eligible veterans and their families may be able to access long-term care facilities, adult day services, and support for caregivers through the VA Health System.20
For veterans, their spouses, and unmarried dependent children who get a VA pension, there are two kinds of monthly payments to afford memory care help: Aid and Attendance benefits and Housebound benefits.21 You can only receive one of these benefits.
You are eligible for Housebound benefits if a permanent disability requires you to spend most of your time indoors. For Aid and Attendance benefits, you must meet at least one of the following guidelines:21
- You need help with activities of daily living like dressing and bathing
- You are mostly in bed because of an illness
- You are staying in a nursing home due to a disability
- You have trouble seeing even with glasses or contact lenses
Contact your local VA office about how to apply for these benefits.
Other payment options for memory care
Other options include long-term care insurance that helps reimburse memory care expenses, a reverse mortgage to turn your home equity into money to pay for memory care, and private assets such as Social Security income, savings, or investments.15
"For many older adults, particularly those living with dementia, long-term care insurance may be difficult to obtain or afford," said Dorothea Vafiadis, NCOA Senior Strategist for Healthy Aging. "But if someone already has a long-term care insurance policy, it may help pay for memory care expenses."
Read NCOA’s guide on Medicare’s coverage of memory care to learn about the benefits and risks of all these options.
