Brain testing for healthy people is mostly about a baseline: a scan or memory test now, so a change later can be spotted. Experts say there isn't enough evidence to screen people without symptoms, and brain scans often find harmless spots. If you've noticed memory changes, see a doctor instead.
The tests, in plain English
It's like taking a photo of your bookshelf before you move. On its own it doesn't tell you much. It helps later, when you want to know if anything changed.
Brain MRI with volumetrics
An MRI of the brain, with software that measures the size of brain areas and compares them with people your age. No radiation. It often finds small spots that turn out to be harmless.
For: People wanting a baseline who are ready for possible follow-upMemory and thinking tests
Computer or paper tests of memory, attention and speed. Your sleep, stress and mood that day can change the score, so a retest uses the same test.
For: People wanting a baseline, or who have noticed small changes
