Scientists discover how obesity may fuel Alzheimer's disease

Researchers from Houston Methodist have uncovered a biological pathway connecting obesity to Alzheimer's disease. The study shows that obesity increases levels of phosphatidylethanolamines (PEs), fat molecules that travel to the brain and disrupt its immune defenses, promoting harmful amyloid buildup.
