Abnormal hyperactivation in the brain could be an early biomarker of Alzheimer s disease
Abnormally hyperactive areas in the brain may help better predict the onset of Alzheimer s disease, according to findings of a research team led by Université de Montreal psychology professor Sylvie Belleville, scientific Director of the Institut universitaire de gériatrie de Montréal research centre.
Hyperactivation could be an early biomarker of Alzheimer s disease, the researchers say in their study published today in
Alzheimer s & Dementia: Diagnosis, Assessment & Disease Monitoring, co-authored by Belleville and Nick Corriveau-Lecavalier, a doctoral student she supervises.
Worried about their memory
In their research, the team found hyperactivation in certain brain areas in people not yet diagnosed with Alzheimer s but who were worried about their memory and who exhibited risk factors for the disease.

Gradual hearing loss is a common symptom of aging, but in some people it may also be an early sign of Alzheimer’s disease or other types of dementia, a new study suggests.
The risk of dementia appears to rise as hearing declines. Older people with mild hearing impairment those who have difficulty following a conversation in a crowded restaurant, say were nearly twice as likely as those with normal hearing to develop dementia, the study found. Severe hearing loss nearly quintupled the risk of dementia.
It s unclear why the loss of hearing and mental function might go hand in hand. Brain abnormalities may contribute independently to both conditions, but it s also possible that hearing problems can help bring on dementia, the researchers say. Hearing loss may lead to social isolation (which itself has been linked to dementia), for instance, or it may interfere with the brain s division of labor.
