Reported by AI Image generated by AI Fact checked
New research finds that blood biomarkers associated with Alzheimer’s disease increase significantly faster in people with obesity than in those without. Drawing on five years of data from 407 volunteers, the study suggests that blood tests can detect obesity‑related changes earlier than brain scans, underscoring obesity as a major modifiable risk factor for Alzheimer’s.
