Brain cells meant to protect us may be fueling cognitive decline

Scientists have uncovered a surprising cause of age-related cognitive decline involving brain cells previously thought to be entirely beneficial. As these cells become dysfunctional, they can produce abnormal amounts of myelin, disrupting nerve fibers and potentially contributing
