Summary

Story summary

Researchers at Houston Methodist link obesity to Alzheimer's via adipose-derived extracellular vesicles (EVs).
EVs from obese individuals show a lipid profile that speeds amyloid-? plaque formation.
The findings provide the first direct molecular evidence linking fat metabolism to brain degeneration.
Dr. Stephen Wong notes obesity is a significant modifiable dementia risk factor; therapies may target EV lipids, pending future studies.
