Simple test can help detect Alzheimer's before dementia signs show, study shows

York University researchers say a simple test that combines thinking and movement can help to detect heightened risk for developing Alzheimer's disease in a person, even before there are any telltale behavioural signs of dementia.

"We included a task which involved moving a computer mouse in the opposite direction of a visual target on the screen, requiring the person's brain to think before and during their hand movements," says Sergio in the School of Kinesiology & Health Science. "This is where we found the most pronounced difference between those with mild cognitive impairment (MCI) and family history group and the two control groups."
