- NCT05697588Recruiting
Study blood and brain markers from mild memory loss to dementia
This study looks for “biomarkers” (measurable signs from blood and brain tests) that may help predict who with mild cognitive impairment (MCI) could later develop dementia. Results may help doctors spot risk earlier and better plan care.

New PET scan for detecting amyloid plaques in the brain
This study tests a newer, shorter PET scan to see if it can detect amyloid plaques (sticky protein clumps linked to memory loss) as well as the standard scan. It may help diagnose cognitive problems with less time in the scanner.
Toronto, OntarioAges 18 years+ - NCT06754579Recruiting
High-volume arm training for physical and mental gains

Tarsus, Mersi̇nAges 18–50 - NCT06254469RecruitingPhase 3
PET scan study for memory decline with head injury or Alzheimer's risk
This trial uses a special PET scan tracer to see if it can predict who will get worse over time. It is for people with mild memory or thinking problems that may be linked to past head injuries or early Alzheimer's disease.
Evanston, IllinoisAges 45 years+ - NCT05836207Recruiting
Rewards for quitting cannabis in young adults
This study tests whether offering rewards can help young adults stop using cannabis. You would attend a treatment clinic and provide supervised urine tests twice each week while aiming to quit.

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.
