A new study by investigators from Mass General Brigham suggests that whether a person inherits risk of Alzheimer’s disease from their mother or father influences risk of biological changes in the brain that lead to disease. By evaluating 4,400 cognitively unimpaired adults ages 65-85, the team found those with a history of Alzheimer’s disease (AD) on either their mother’s side or both parents’ sides had increased amyloid in their brains. Their results are published in JAMA Neurology.
