Can a diabetes drug and nasal insulin boost brain health?
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.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a combination of intranasal insulin (Actrapid) and oral semaglutide (Rybelsus)
- What this could lead to
- If it works, this could point toward a new way to slow cognitive decline in people at high risk for dementia.
- What could go wrong
- This is a small, early feasibility study. The combination may cause side effects like nausea or not improve cognition. Results may not apply to everyone.
