People with a known, high risk for Alzheimer's disease develop abnormal brain function even before the appearance of telltale, amyloid plaques that are characteristic of Alzheimer's disease, according to a new study. The findings suggest that a gene variant affects brain function long before the brain begins accumulating the amyloid that will eventually lead to dementia.
