Study of Protective Gene Variant Provides Insight into Delaying Onset of Alzheimer’s Dementia
Alzheimer’s disease is currently the seventh leading cause of death in the U.S. While your likelihood of developing Alzheimer’s-related cognitive impairment increases with age, risk for this disease and age of its onset depend on many factors, including the genes you carry. An intriguing new study suggests that having just one copy of a protective gene variant may be enough to delay cognitive impairment from this devastating disease in individuals who are otherwise genetically predisposed to developing early-onset Alzheimer’s dementia. The findings, from a study supported in part by NIH and reported in The New England Journal of Medicine, offer important insights into the genetic factors and underlying pathways involved in Alzheimer’s dementia. While much more study is needed, the findings have potential implications for treatments that could one day work like this gene variant does to delay or perhaps even prevent Alzheimer’s dementia.
