A recent study reveals that people with multiple sclerosis (MS) may have a reduced risk of developing Alzheimer’s disease. Researchers found that individuals with MS are about half as likely to exhibit amyloid-beta plaques in the brain, a hallmark of Alzheimer’s. This suggests that certain biological or genetic factors related to MS might offer some protection against Alzheimer’s, though the exact reasons remain unclear. The study’s findings could have significant implications for developing future treatments for Alzheimer’s.
