Semaglutide Slowed a Blood-Based Dementia Risk Score in Older Heart Patients
Graded Moderate — post hoc analysis of a randomized trial in 2,970 adults aged 65 and over across 104 weeks, though the outcome was a predicted-risk protein score rather than dementia itself.

This analysis suggests GLP-1 drugs may affect brain-related blood markers, though actual dementia outcomes remain untested.
Older adults with excess weight and heart disease but no diabetes took semaglutide or a placebo for two years. A 25-protein blood test that predicts future dementia risk rose much less in the semaglutide group. This isn't proof of fewer dementia cases, just a slower rise in a risk marker. Still, it adds to the idea that GLP-1 drugs may do something for the aging brain.
Conflict of Interest Disclosure: Two authors work for and own shares in Novo Nordisk, which makes semaglutide; another author consults for Novo Nordisk.
