Could a zap to the ear boost memory in diabetes patients?

NCT ID NCT07642518

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a mild electrical stimulation applied to the ear (via a small device) can improve memory and thinking in people with type 2 diabetes who also have mild cognitive impairment. The trial will involve 38 participants who will either receive the active stimulation or a sham (fake) version for 24 weeks. The main goal is to see if this non-invasive treatment can help slow or improve cognitive decline.

What this could mean

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

Active substance

transcutaneous auricular vagus nerve stimulation device

What this could lead to

If it works, this could point toward a non-drug, at-home treatment to slow memory decline in people with type 2 diabetes.

What could go wrong

This is a very small, early-stage trial with only 38 people, so results may not apply widely. The sham control group also receives a device, so the real benefit may be small or hard to detect.
