Use of a novel approach to analyzing brain structure that focuses on the shape rather than the size of particular features may allow identification of individuals in early presymptomatic stages of Alzheimer’s disease. A team of Massachusetts General Hospital (MGH) investigators using advanced computational tools to analyze data from standard MRI scans report that individuals with Alzheimer’s disease, including those diagnosed partway through a multi-year study, had greater levels of asymmetry - differences in shape between the left and right sides of the brain - of key brain structures. Their study has been published online in the journal Brain.
