Diagnosing dementia early gives us more time to put precautions in place and to study exactly how the condition progresses – and a new method for predicting conditions such as Alzheimer’s disease is promising up to nine years of advance warning.

In tests, the model was more than 80 percent accurate at predicting the development of dementia. That has huge potential in terms of early diagnosis, and it also addresses another challenge: the large number of people with dementia who don’t get diagnosed at all.
