Dementia and Alzheimer’s Self-Tests: Check Yourself or a Loved One

Not sure whether a change in memory is worth taking seriously? These free, private self-tests help you decide. Pick one below: check your own memory, or answer questions about a parent, partner, or friend you are worried about.

Each self-test takes under 10 minutes, needs no sign-up, and does not save your answers on our servers. At the end you see where your answers fall and what doctors usually suggest at that point. A self-test cannot diagnose dementia or Alzheimer’s disease. It can only help you decide when to talk to a doctor.

About these self-tests

Not a diagnosis. These self-tests are for general information only. They are not medical tests, they cannot diagnose dementia, Alzheimer’s disease, or any other condition, and they do not replace advice from a doctor or other qualified health professional.

How they were built. They use the kinds of tasks and questions that clinicians commonly use to look at memory and thinking. The words, numbers, questions, and scoring are our own and simplified. They have not been clinically validated, and their results cannot be compared with scores from standard clinical tests.

What the result means. A result only shows how your answers compare with the kinds of changes doctors ask about, and whether it may be worth talking to a doctor. A good result does not rule anything out, and a low result does not mean something is wrong. If you or people close to you notice changes, talk to a doctor, whatever the result says.

What can affect results. Sleep, stress, anxiety, low mood, illness, pain, medications, hearing or vision problems, distractions, and how comfortable you are with a computer can all change how you do. A result is only a snapshot.

Emergencies. If confusion or memory problems start suddenly, or come with a drooping face, weakness on one side, trouble speaking, a severe headache, or fainting, call 911 or your local emergency number right away.

Your privacy. While you take a self-test, your answers are kept only in a temporary cookie in your own browser. They are not saved in a database or shared with anyone, and they disappear when you close your browser or choose “Start over.”

Who they are for. These self-tests are intended for adults (18 and older).

Why it is worth a few minutes

  • About 57 million people worldwide were living with dementia in 2021, and nearly 10 million new cases occur every year, according to the World Health Organization.
  • An estimated 7.4 million Americans age 65 and older are living with Alzheimer’s dementia in 2026, according to the Alzheimer’s Association.
  • Dementia is not only a condition of the very old: up to 9% of cases begin before age 65.
  • Many things that cause forgetfulness, such as poor sleep, stress, depression, thyroid problems, low vitamin B12, or side effects of medicines, are treatable. Looking into changes early gives you and your doctor more options.
