A gene long thought to just raise risk for Alzheimer’s may cause some cases

“For the first time, researchers have identified a genetic form of late-in-life Alzheimer’s disease — in people who inherit two copies of a worrisome gene. Scientists have long known a gene called APOE4 is one of many things that can increase people’s risk for Alzheimer’s, including simply getting older. The vast majority of Alzheimer’s cases occur after age 65. But research published Monday suggests that for people who carry not one but two copies of the gene, it’s more than a risk factor, it’s an underlying cause of the mind-robbing disease. The findings mark a distinction with ‘profound implications,’ said Dr. Juan Fortea, who led the study the Sant Pau Research Institute in Barcelona, Spain.” (05/07/24)
