NCT ID NCT06072963

First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time

Summary

This study tests whether combining a daily oral diabetes medication (semaglutide) with a nasal insulin spray can improve memory, thinking, and blood flow in the brain. The trial enrolls older adults with mild cognitive impairment and metabolic syndrome, a group at high risk for dementia. Participants take the drugs for up to 12 months while researchers track changes in cognition and brain scans.
