Light and sound training to help prevent Alzheimer’s memory loss
This study tests whether regular “gamma” light and sound stimulation can delay or prevent Alzheimer’s disease-related memory decline in people who are currently not showing dementia but are at higher risk. It uses brain testing (MRI and PET) and memory/language tests over about 13 months.
Boston, MassachusettsAges 55–90 - NCT05777486Recruiting
Study on how TikTok food posts affect kids’ thinking
This study looks at whether food ads posted on TikTok by influencers change what children eat and how they think. It mainly involves U.S. children ages 10–13 who use TikTok often and can read and speak English.

Brain scan and stimulation study for kids with mild concussion
This study tests whether a brain “stimulation” approach, paired with brain imaging (MRI), can help children who still have symptoms after a mild concussion. There is also a comparison group of children without concussion history.
Buffalo, New YorkAges 10–15 - NCT05765110Recruiting
Tracking speech, movement, and thinking in Parkinson’s disease
This study looks at how people with Parkinson’s disease speak, move, and think to see whether these patterns can act like a “biomarker” (a measurable sign) of the disease. It also involves healthy volunteers to compare results.
PragueAges 30–75 - NCT05746767Enrolling by invitation

Common questions
- Are there clinical trials for cognition?
- Yes. Clin2 currently lists 1,981 recruiting cognition studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cognition trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cognition trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
