Is abnormal brain hyperactivity an early sign of Alzheimer disease?

Research led by former PhD student Nick Corriveau-Lecavalier and Sylvie Belleville, laboratory director at the Institut universitaire de gériatrie de Montréal and professor in the Department of Psychology at Université de Montréal, has shown that abnormal hyperactivation in certain areas of the brain, including the hippocampus and parietal lobe, may constitute an early sign of Alzheimer disease in at-risk individuals. Indeed, brain hyperactivity combined with genetic and cognitive tests could become a biomarker to pinpoint the disease several years before the first clinical signs, such as difficulties with memory, judgment and speech, ever appear.
