NCT ID NCT07675499

First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time

Summary

This study investigates whether combining intranasal insulin (delivered as a nose spray) with high-intensity exercise can improve brain blood flow, insulin sensitivity, and thinking skills in older adults with type 2 diabetes. Participants aged 55–80 will receive either insulin or a placebo spray twice daily plus a 16-week exercise program. The goal is to see if this dual approach helps protect the brain from age-related decline.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

intranasal insulin

What this could lead to

If it works, this combination could point toward a non-drug way to protect brain health and thinking skills in people with type 2 diabetes.

What could go wrong

This is a mid-stage trial with only 60 participants, so results may not apply to everyone. The approach is experimental and may not show clear benefits.
