Story summary
- A study links obesity to Alzheimer's by identifying extracellular vesicles from fat cells signaling amyloid-? plaque formation in the brain.
- Researchers say these vesicles contribute to plaque buildup, offering a target to lower risk for obese individuals.
- Experts caution obesity is not proven to cause Alzheimer's, but may be a modifiable risk factor with inflammation affecting brain health.
