Scientists Discover How Obesity May Trigger Alzheimer's Disease

Houston Methodist researchers found that obesity raises phosphatidylethanolamines in body fat.

These fat-derived molecules can reach the brain and disrupt immune and cell signaling linked to Alzheimer’s disease.

In Alzheimer’s models, restoring the lipid balance improved brain function and reduced harmful effects.

The findings suggest a new way to slow disease by targeting obesity-related fat signals, not just the brain.
