Scientists discover the brain may enter a new biological phase between 50 and 75

A Hidden Brain Change May Begin at 50

For decades, scientists have known that age is the strongest risk factor for Alzheimer’s disease, yet age itself does not explain why the brain becomes vulnerable. A new NIH-funded study offers a surprising clue: the brain’s own immune workforce may begin changing identity during middle age. The shift was found in the hippocampus, a region […] The post A Hidden Brain Change May Begin at 50 appeared first on Knowridge Science Report.

Scientists discover the brain may enter a new biological phase between 50 and 75

New research suggests the brain may enter a distinct stage of aging between roughly ages 50 and 75. Scientists found that cells involved in protecting the brain begin to change during this period, while the organization of DNA inside brain cells also becomes less structured. The findings offer a closer look at why advancing age remains one of the strongest risk factors for memory decline and neurodegenerative diseases. Researchers observed that …
