Active Studies

Sleep, Brain Waste Clearance, and Memory

Ages 50–85 Up to $590 compensation Glymphatic TMS Study

We are developing methods for preventing age-related memory decline using Transcranial Magnetic Stimulation (TMS), a non-invasive technique already proven safe and effective for treating depression and migraines. This study examines how TMS may support the brain's glymphatic system — a waste-clearance pathway active during sleep that may play a role in protecting memory and brain health.

You may be eligible if you are: 50–85 years old, experiencing memory complaints, right-handed, and fluent in English (it does not have to be your first language).

What's involved: Three blocks of non-invasive brain stimulation (two blocks of 5 sessions), MRI scans, cognitive testing, blood draws, and a cheek swab. All visits are in person at the University of Arizona (1230 N Cherry Ave, Tucson).

Nutrition and Brain Plasticity

Recruiting Ketone TMS Study

Emerging evidence suggests that dietary ketones may influence neural plasticity. This study combines ketone supplementation with Transcranial Magnetic Stimulation (TMS) to investigate the downstream neural interactions between metabolic and stimulation-based approaches to brain health.

Full eligibility criteria and study details will be shared during initial screening. Use the "Sign up to participate" button above to express interest, and our team will follow up with more information.

All studies are reviewed and approved by The University of Arizona Institutional Review Board.
