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 to worsening memory and thinking skills.
A study on Nature Medicine reveals the dark side of oligodendrocytes: when NRF2 protein goes out, myelin stifles nerve fibers and accelerates dementia. There are already drugs that can intervene. The article When the guard cells of the brain stop protecting it: the unexpected role of oligodendrocytes in cognitive decline comes from Economic Scenarios.
Researchers at the University of Edinburgh have identified a new factor that can contribute to age-related cognitive decline. The study reveals that brain cells, previously considered beneficial, can become dysfunctional and negatively impact memory and thinking skills. Discovered on brain protective cells The cells responsible for keeping the protective layer around nerve fibers, known as oligodendrocytes, can become dysfunctional with aging. T…
