Researchers at Brigham and Women’s Hospital (BWH) and Massachusetts General Hospital (MGH) have found an association between lower weight and more extensive deposits of the Alzheimer’s-associated protein beta-amyloid in the brains of cognitively normal older individuals. The association — reported in the Journal of Alzheimer’s Disease — was seen in particular among individuals carrying the APOE4 gene variant, which is known to increase the risk of Alzheimer’s.
