(Science Alert) Dementia Breakthrough: Brain Scans Predict Disease Up to 9 Years Early

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.

The method, developed by a team from the Queen Mary University of London in the UK and Monash University in Australia, involves a neurobiological model that analyzes brain scans captured by functional magnetic resonance imaging, or fMRI.

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.

“Predicting who is going to get dementia in the future will be vital for developing treatments that can prevent the irreversible loss of brain cells that causes the symptoms of dementia,” says neurologist Charles Marshall, from the Queen Mary University of London.
