Research has revealed that individuals with multiple sclerosis (MS) are significantly less likely to exhibit the molecular signs of Alzheimer’s disease, suggesting a protective element in MS that could inspire new Alzheimer’s treatments. The study found that MS patients had 50% less amyloid plaque accumulation, a key indicator of Alzheimer’s, compared to non-MS individuals. This connection between MS and reduced Alzheimer’s risk highlights potential immune-related mechanisms that may be leveraged for therapeutic strategies.
