Test for dementia 30 questions: a family guide to cognitive assessment
The "30-question test for dementia" usually means a short memory and thinking screen scored out of 30 points, such as the Mini-Mental State Exam (MMSE) or the Montreal Cognitive Assessment (MoCA). It takes about 10 to 15 minutes. It can flag a problem, but it can't diagnose dementia on its own.
What is a cognitive assessment for dementia?
A cognitive assessment is a set of questions and simple tasks that checks memory, attention, language, problem-solving and other thinking skills. Doctors use it to see whether thinking has changed and whether more testing is needed.
If you've noticed your mom repeating herself or your husband struggling with bills, a cognitive test is often the first step toward answers. It's quick, it doesn't hurt, and it gives the doctor a starting point to compare against later.
Memory problems in older adults have many possible causes. Some, like medicine side effects or depression, can be treated. That's one of the best reasons to get checked.
What is the 30 question cognitive test for dementia?
When people search for the "test for dementia 30 questions," they usually mean one of a few screening tests that are scored out of 30 points:
- Mini-Mental State Exam (MMSE). One of the oldest and best-known screens.
- Montreal Cognitive Assessment (MoCA). Often used to pick up milder changes.
- Saint Louis University Mental Status exam (SLUMS). Similar in length and style.
Each test has a mix of questions and tasks. Not every point is a separate question, so the "30 questions" are really 30 points across several short sections.
What are the 30 questions on a cognitive test?
We don't post the actual test questions here. Several of these tests are copyrighted, and they only work when a trained person gives them the same way every time. Practicing in advance can also make the results less useful.
What we can tell you is what the questions check. Most 30-point screens include:
- Orientation. Knowing the date, day, place and city.
- Memory. Learning a short list of words and recalling them a few minutes later.
- Attention. Counting backward, spelling a word backward or repeating numbers.
- Language. Naming common objects, repeating a sentence, following a spoken or written instruction.
- Visual and planning skills. Copying a shape or drawing a clock.
- Thinking skills. Finding similarities between words or solving a simple problem.
The tests are short, and most people find them a little awkward, not scary. It helps to tell your person it's a routine check that many people their age have.
What is the most common cognitive test for dementia?
There isn't one single test every doctor uses. These are among the most common:
- Mini-Cog. A very quick screen: remember three words, draw a clock, then recall the words.
- MMSE, MoCA or SLUMS. Longer 30-point screens that look at several thinking skills.
- AD8. A short checklist answered by a family member or close friend about changes they've noticed.
- SAGE. A paper test the person can fill out on their own, then take to the doctor.
Brief screens like these take about 10 minutes or less. The doctor picks the tool that fits the person, their language and their education.
When should someone have a cognitive assessment?
Ask the doctor about a memory screen when:
- The person, a family member or a friend has noticed changes in memory or thinking
- The doctor notices problems during a visit
- The person is having new trouble managing money or medicines
The National Institute on Aging's guide for doctors also points to age 80 or older, and health factors like type 2 diabetes, past stroke, depression or fewer years of schooling, as reasons to consider screening.
Finding a problem early has real benefits. A treatable cause may be found. If it is dementia, the person can take part in planning, safety issues can be addressed sooner, and the family can get support and information.
If you're on Medicare, a check for cognitive changes is part of the yearly Medicare Annual Wellness Visit. You can ask for it by name.
What happens during a cognitive assessment?
Here's what to expect:
- A short screening test. A doctor, nurse or trained staff member asks the questions. It takes about 10 minutes or less for a brief screen.
- Time with the person alone. Doctors often talk with the person on their own first so family can't prompt the answers. It's normal, so don't take it personally.
- Time with the family. The doctor may then ask you about changes at home: memory, mood, behavior, driving and handling money. Your person may need to give permission for the doctor to talk with you.
- Next steps. If the screen raises concerns, the doctor will suggest a fuller evaluation or a referral to a specialist, such as a geriatrician, neurologist, geriatric psychiatrist, neuropsychologist or memory disorder clinic.
A screen is only the first step. Our guide to how dementia is diagnosed explains the full evaluation.
How to help a parent prepare for a memory test
Many families worry about how to bring it up. People who are starting to have trouble are often very good at covering it up, and they may be afraid of what the test will show.
- Keep it low-key. Call it a routine checkup or part of the yearly wellness visit.
- Send the doctor a note first. List the changes you've seen, with examples, so the doctor knows what to look for.
- Make sure glasses and hearing aids come along. Poor vision or hearing can lower a score.
- Schedule at their best time of day, often the morning, and make sure they've eaten and slept.
- Bring a list of every medicine, including vitamins and over-the-counter pills.
- Don't quiz them at home beforehand. It adds stress and can affect the results.
The NIA guide in the download below was written for doctors, but many families find it useful to bring along to the appointment.
What if the screening shows a problem?
A low score doesn't mean your person has dementia. It means more testing is needed to find out why. Many things can affect a score, including stress, a bad night's sleep, an infection, hearing loss, depression, medicine side effects, or a first language other than the test's.
If more testing confirms dementia, read what to do after a dementia diagnosis. Whatever the result, you don't have to sort it out alone.

Cognitive tests for dementia: common questions
Can a cognitive test diagnose dementia?
No. A cognitive test is a screening tool. It can show that thinking skills have changed, but a diagnosis needs a full evaluation, including a medical history, exams, lab tests and often brain scans.
What are the three words to remember for a cognitive test?
There's no set list. Tests like the Mini-Cog use three unrelated, everyday words, and the words change from one version to another so people can't memorize them. The point is to see whether the person can hold on to new information for a few minutes.
What is the 10 question cognitive test?
Several short screening tests have about 10 questions or items, often on orientation, memory and attention. They're designed to be quick. Like longer tests, they flag possible problems rather than diagnose dementia. Ask the doctor which test they used and what the score means.
What is the 12 question dementia test?
Short screening tests and questionnaires come in many lengths, including some with around 12 questions. Some are answered by the person, others by a family member. Any of them can suggest whether more testing is needed, but none can diagnose dementia.
What does a cognitive test score mean?
Higher scores usually mean fewer problems. But what counts as normal depends on the test, the person's age, education and language. Ask the doctor to explain the score, what it suggests and what comes next. One score is most useful as a baseline to compare against later.
Is there a free cognitive test for dementia online?
Some screens, like the self-administered SAGE test, can be done at home on paper. Online quizzes vary a lot in quality. Whatever you use, take the results to a doctor rather than relying on a home score, since many treatable things can affect results.
Where can I find a dementia screening test PDF?
Some tests, such as SAGE, are available to print from the organizations that created them. Others are copyrighted and meant to be given by trained staff. The most reliable route is to ask the doctor for a screening at the next visit or at the Medicare Annual Wellness Visit.
Does Medicare cover a cognitive assessment?
A check for cognitive changes is part of the Medicare Annual Wellness Visit. If problems are found, Medicare also covers follow-up visits to evaluate them. Check with your plan about any costs.
What is the best type of exercise for memory loss?
Regular aerobic exercise, like brisk walking, swimming or dancing, is good for the heart and the brain. Studies of older adults who walked regularly found improvements in planning skills. Check with the doctor before starting a new routine. See how to prevent Alzheimer's for more.
How often should someone have a memory screening?
There's no fixed rule. Many people have a check at their yearly Medicare wellness visit. If you notice new changes between visits, don't wait. Call the doctor. Our Alzheimer's and dementia FAQ covers more about memory screening.
