At-Home and Online Memory Tests

At-home and online memory quizzes can flag possible problems and start a conversation with your doctor, but none can diagnose dementia; here is how they work, which are reputable, and what to do with the results.

Worried about your memory and not sure whether it's worth a doctor's visit? It's tempting to search for an online quiz. Some at-home tests are reputable and genuinely useful; others are marketing tools. None of them can tell you whether you have dementia. Here's how to use them wisely.

What at-home memory tests can and can't do

They can:

• Give you a rough snapshot of memory, attention, problem-solving and language
• Create a baseline you can compare against later
• Help you decide whether to bring up concerns with your doctor
• Give the doctor something concrete to look at

They can't:

• Diagnose dementia, Alzheimer's or mild cognitive impairment
• Rule out a problem: a "normal" score doesn't mean everything is fine if you or your family see real changes
• Tell you the cause of memory problems, many of which are treatable (see Reversible Causes of Memory Problems)

Scores are affected by many things that have nothing to do with dementia: poor sleep, anxiety, depression, hearing or vision problems, pain, medications, education level, language and familiarity with computers.

Reputable options

SAGE (Self-Administered Gerocognitive Exam). Developed at The Ohio State University Wexner Medical Center, SAGE is a paper-and-pencil test you can download free and take at home, usually in 10 to 15 minutes with no time limit. It checks orientation, language, reasoning, memory and visual-spatial skills. Ohio State recommends taking it and bringing the completed test to your doctor to score and interpret. There are four interchangeable forms, which makes it easier to repeat over time.

Tests your doctor uses. Brief screening tests such as the Mini-Cog, MoCA (Montreal Cognitive Assessment) and MMSE are designed to be given by a trained professional, not self-administered. They're commonly used in doctors' offices, including during the Medicare Annual Wellness Visit, which includes a check for cognitive impairment. See Cognitive Screening Tests (MMSE, MoCA).

Digital tests through health systems and research studies. Some clinics and research programs use tablet-based tests, and online research registries may offer regular memory tasks as part of a study. These can be useful, especially for tracking change over time.

Be cautious with

• Quizzes that end in a sales pitch for supplements, "brain-boosting" programs or paid reports (see Supplements and Memory Claims)
• Tests that give a diagnosis or a "brain age"
• Sites that don't say who made the test, whether it has been studied, or what they do with your data
• Direct-to-consumer blood tests for Alzheimer's ordered without a doctor. These tests are designed for people who already have symptoms and are best interpreted alongside a full evaluation (see Blood Tests for Alzheimer's)

How to take an at-home test well

1. Choose a good time. Be rested, fed, and not rushed or upset.
2. Use your glasses and hearing aids.
3. Take it alone and honestly. Don't look things up or have someone help; you want an accurate picture.
4. Write down the date and anything that may have affected your performance, like a bad night's sleep or a new medicine.
5. Keep the results and take them to your doctor.

What to do with your results

If your score is lower than expected: Don't panic. Make an appointment with your primary care doctor and bring the test. Many causes of memory trouble are treatable, such as low vitamin B12, thyroid problems, depression, sleep apnea and medication side effects (see Sleep Apnea and Memory and Medications That Can Affect Memory).

If your score is normal but you're still worried: Trust what you and your family are noticing in daily life. Changes like getting lost in familiar places, repeating questions or struggling with bills are more meaningful than any quiz.

If you'd like to track over time: Repeat the same type of test once a year or when you notice changes, and share the trend with your doctor.

What a real evaluation includes

A full evaluation looks at your medical history, medicines, mood and daily functioning, along with cognitive testing, a physical and neurological exam, blood tests and sometimes brain imaging or Alzheimer's biomarker tests. A family member's description of changes is often especially valuable. See Getting a Diagnosis, Which Doctor Diagnoses Dementia? and Preparing for a Memory Appointment.

The bottom line

A reputable at-home test like SAGE can be a useful first step and a good conversation starter. Treat the result as a reason to talk to your doctor, not as an answer. Real changes in daily life matter more than any score.
