PolyU Study Ties 18,000-Person Visceral Fat Data to White Matter Damage and Faster Brain Aging

Summary
More than 18,000 UK Biobank participants showed that fat location—not weight or BMI alone—tracked distinct patterns of brain structure, connectivity and cognitive change, according to a PolyU-led Nature Mental Health study.
Visceral fat was the only fat type directly linked to white matter damage, a finding that points to higher risk in brain pathways tied to vascular cognitive impairment and small vessel disease upstream of dementia.
Researchers said arm, leg and trunk fat each mapped to different brain systems, while visceral fat likely harms the brain through chronic low-grade inflammation and neuroinflammation.
The study is observational and does not prove causation, but the team said visceral fat is a modifiable risk factor that could be reduced through targeted lifestyle interventions.
