Gamma Light and Sound Stimulation to Prevent Dementia in Cognitively Normal People At Risk for Alzheimer's Disease

Alzheimer's disease (AD) is characterized by significant memory loss, toxic protein deposits (amyloid and tau) in the brain, and changes in the gamma frequency band on EEG. Gamma waves are important for memory, and in patients with AD, there are fewer gamma waves in the brain. The Tsai lab found that boosting gamma waves in AD mouse models using light and sound stimulation at 40Hz not only reduced amyloid and tau in the brain, but also improved memory. A light and sound device was developed for humans that stimulates the brain at 40Hz that can be used safely at home. The goal of this study is to see if using this device can prevent dementia in people who are at risk for developing Alzheimer's disease.

How this works

  1. Answer a few questions

    About 5 to 10 minutes. Skip-friendly where possible.

  2. We forward your profile to the study team

    They see only the answers needed to decide if you can be screened.

  3. The team reaches out to schedule screening

    Usually within a few business days, via the contact you give.
