The 30-Second Dementia Test — What Caregivers Should Know
When you’re worried about a loved one, even small tools can feel important. One simple task has gained attention for spotting early dementia signs — often called the 30-second dementia test.
Here’s what caregivers need to know.
What is the test?
The test involves drawing a traditional clock face from memory.
All you need is:
A pen
Paper
Something to track 30 seconds
The person is asked to draw a clock showing 10 minutes past 11 within 30 seconds.
How the test is assessed
Experts look at six areas:
Were all 12 numbers included?
Were the numbers spaced evenly?
Were any numbers jumbled or missing?
Were the clock hands pointing correctly?
Were the hour and minute hands the correct length?
Was the task completed within the time limit?
This task tests multiple brain functions at once — not just memory.
Why it matters for caregivers
The clock-drawing test can highlight:
Planning difficulties
Visual-spatial problems
Conceptual confusion
Experts suggest it can sometimes be more revealing than memory tests alone.
Important cautions
This is not a diagnosis
Failing the test doesn’t automatically mean dementia
Anxiety, stress, or low confidence can affect performance
For caregivers, this test can be a conversation starter, not a conclusion.
