Altered brain connections in early Alzheimer’s disease

Although a lot is known about brain alterations in symptomatic Alzheimer’s disease (AD), less is known about changes in the brain network early in the disease process. In a study published in Psychiatry Research: Neuroimaging last year, researchers discovered that the left parietal region—a brain area that is also affected in symptomatic AD—becomes unusually important in the brain connections of people with pre-clinical AD.
