Psilocybin study for depression in mild memory or early Alzheimer’s
This early-phase study tests whether psilocybin (a psychedelic substance) can help with depression in people who have mild memory problems or early Alzheimer’s. The trial also closely monitors safety, thinking changes, mood, and blood pressure before and after dosing.
Baltimore, MarylandAges 18–85 - NCT06223672Recruiting
Healthy fats for better thinking in older adults
This study tests whether healthy fats can help improve thinking and memory in people with mild memory concerns. It is for people with overweight and normal blood sugar.
Columbus, OhioAges 40–75 - NCT06809725Enrolling by invitation
Study of a headband device for cognitive health check
This study tests a new way to check cognitive (thinking and memory) health using a simple headband that measures electrical signals on your scalp. It is looking for people 65 to 90 years old, with or without memory concerns, and a family member or friend who can also take part.
Miami, FloridaAges 65–90 - NCT07284446Recruiting
Depression, memory, and outcomes in heart failure patients
This study looks at how depression and memory problems affect recovery in people hospitalized with worsening chronic heart failure. It aims to find better ways to support patients during their hospital stay.
KaunasAges 18–85 - NCT06411561Recruiting
Boosting memory after ICU stay for older adults
This study tests a combination of activities (like cognitive training and exercise) to help older adults recover thinking and memory after a serious illness in the ICU. It may help you regain sharpness and independence after leaving the intensive care unit.
Seattle, WashingtonAges 60 years+ - NCT05624632Enrolling by invitation
Online cognitive tests you can do remotely
This study checks how well an online remote testing approach measures thinking and memory. It may help researchers collect cognitive data more easily, especially by combining it with other related studies.
BarcelonaAges 45–80 - NCT07109830Recruiting
Brain-computer game for thinking skills in kids
This study tests a brain-computer game that uses brain waves to measure thinking skills in kids ages 7-16 with or without movement challenges. The goal is to see if the game can help evaluate cognitive abilities in a fun way.
Edmonton, AlbertaAges 7–16 - NCT06897670Recruiting
Brain blood flow patterns in mood and memory disorders
This study uses a headband with light sensors (fNIRS) to measure blood flow in the brain while you do thinking tasks. It aims to understand differences in brain activity for people with depression, bipolar disorder, or mild memory loss.
Rochester, MinnesotaAges 18 years+ - NCT05830422Enrolling by invitation
Predicting late thinking problems after cardiac arrest
This study looks at how to predict delayed cognitive (thinking) impairment in people who survived a cardiac arrest but initially seemed neurologically okay. It may help identify who is at higher risk so follow-up and support can be planned earlier.
Daejeon, Seo-guAges 18 years+ - NCT04335994Recruiting
Home sleep testing for people with memory trouble
This study looks at how well home sleep apnea testing works for people with cognitive impairment (memory/thinking problems) to help improve outcomes. You may be asked to do a home sleep test (and possibly an in-lab test) and will involve a caregiver if needed.

Common questions
- Are there clinical trials for cognitive impairment?
- Yes. Clin2 currently lists 575 recruiting cognitive impairment 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 cognitive impairment 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 cognitive impairment 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.
