Scientists May Have Discovered How Alzheimer's Disease Spreads Through the Brain

Scientists have discovered a new mechanism that may explain how Alzheimer's disease spreads through the brain. A protein called Arc, which normally helps brain cells communicate, appears to transport toxic Tau proteins from damaged neurons to healthy ones using tiny extracellular vesicles. The findings, based primarily on mouse studies, suggest that future treatments could slow Alzheimer's progression by blocking this transfer rather than removing Tau entirely. While the research is promising, experts caution that human studies are still needed before therapies can be developed.
