A new study reveals how a common genetic mutation linked to Alzheimer’s disease may accelerate brain cell damage by disrupting the normal breakdown of proteins. Researchers found that the mutation interferes with the cellular process responsible for clearing toxic protein buildup, which is already impaired in healthy aging. The discovery could offer fresh insights into why some individuals develop the disease earlier or more aggressively than others. Experts suggest these findings may eventually lead to targeted treatments aimed at restoring protein clearance mechanisms.
