Scientists discover a protein that protects the brain from Alzheimer’s damage A natural brain protein may help block the toxic tau damage that drives Alzheimer’s disease and other dementias.

https://www.sciencedaily.com/releases/2026/07/260718010140.htm A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer’s disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and healthier connections between neurons, while mice without it experienced more severe damage. The findings also revealed a possible drug target that could help control harmful activity in supporting brain cells.
