Recruiting studies
- NCT04672174Enrolling by invitation
Cognitive screening study for adults with hearing loss
This study checks how well people with hearing loss perform on thinking and memory tests (cognitive screening). It may help researchers find better ways to spot thinking changes in people with hearing loss and understand what factors are involved.

Testing a stress-blocking drug for early Alzheimer's risk
This study tests a new medication, CORT108297, that may help protect the brain from the harmful effects of stress in people at risk for Alzheimer's disease. It is looking for adults age 55 and older who either have mild memory problems or are healthy but have a family history, APOE4 gene, or memory concerns.
Baltimore, MarylandAges 55 years+ - NCT04495660Recruiting
Brain and hearing testing after cochlear implants in children
This study uses a non-painful brain-light monitor to check how hearing and thinking skills change after a cochlear implant in deaf children. It also compares results with children who have normal hearing.
ToulouseAges 10 months–7 years - NCT04570085RecruitingPhase 3
Caffeine treatment to improve thinking in Alzheimer’s disease
This trial tests whether changing caffeine intake can improve thinking and brain function in people with Alzheimer’s disease. You may qualify if you can follow a low-caffeine diet and have stable Alzheimer’s treatment and sleep/heart conditions.
AmiensAges 50 years+ - NCT04419272RecruitingPhase 4
Methylphenidate for thinking problems in adults with focal seizures
This trial studies whether methylphenidate (a stimulant medicine) can improve thinking and memory problems related to epilepsy. You may be kept on your usual seizure medicines, and your thinking will be tested over about 16 weeks.
Miami, FloridaAges 18 years+ - NCT04396873RecruitingPhase 1
PET brain scan study of inflammation markers in neurodegeneration
This Phase 1 study tests a PET scan to measure inflammation-related changes in the brain using a medication called ketoprofen. It may help researchers understand which people with certain brain diseases could benefit from treatments aimed at inflammation.
Bethesda, MarylandAges 18–99 - NCT04467502Recruiting
Virtual reality therapy for gambling urges
This trial tests whether virtual reality exposure therapy can help people with gambling disorder by safely practicing facing gambling-related triggers. It may help you reduce urges and improve control, if you meet the study’s specific criteria.
AmiensAges 18 years+ - NCT04380051Recruiting
Sensory touch therapy to help parents bond with very preterm babies
This study tests whether a gentle sensory “stimulation” approach can improve how parents and very preterm babies interact and support the baby’s social development. If you qualify, you and your baby would be asked to take part so researchers can see whether this early intervention helps bonding and social skills.
ReimsAges Up to 1 day - NCT04482660Enrolling by invitation
PET brain scan study of tau protein in ALFA volunteers
This study uses a special PET brain scan tracer to measure “tau” protein clumps in the brain. It’s meant to better understand brain changes in people who are already part of the ALFA research program, and may help researchers connect tau levels with memory and thinking.
Barcelona, BarcelonaAges 45 years+ - NCT04400617Recruiting
Improving sleep in assisted-living residents
This study looks at sleep quality in people living in assisted-living. It aims to see what changes (or routines) may improve sleep, especially in residents who are physically independent.
Calgary, AlbertaAges 50 years+ - NCT04349852Recruiting
Memory and attention training for adults after brain injury
This trial tests a therapy that helps improve verbal working memory and attention in adults who had a traumatic brain injury (TBI). It may help by training thinking skills that are often affected after an injury, but it’s only for people who meet timing and mental health substance-use requirements.
New York, New YorkAges 18 years+ - NCT04262206RecruitingPhase 4
Testing how statins affect outcomes in adults 75 and older
This trial studies whether cholesterol-lowering medicine (a statin, specifically atorvastatin) improves health and benefits in people age 75 and older in everyday life. It may help doctors understand which older adults benefit most and how to use these medicines safely.
Birmingham, AlabamaAges 75 years+ - NCT04335487Recruiting
Online therapy program for PTSD symptoms in public safety workers
This study tests an internet-based cognitive-behavioral therapy (an online talk-therapy style program that helps you manage thoughts and feelings) to reduce PTSD symptoms in public safety personnel. You may be able to join if you have PTSD-like symptoms and can safely take part in online treatment.
Regina, SaskatchewanAges 18 years+ - NCT04300998Recruiting
CAR-T therapy study for older adults
This study looks at how well CAR-T cell therapy works and how safely it can be given to older adults. It is for people whose cancer or related blood condition has come back or did not respond, and who are receiving a standard (commercial) CAR-T product.
New York, New YorkAges 60 years+ - NCT04267003Recruiting
Brain stimulation study for thinking and brain chemistry in schizophrenia
This study tests whether a brain stimulation approach can improve thinking (cognition) in people with schizophrenia and how it changes brain electrical signals and a brain chemical called GABA. It may help researchers understand new ways to support thinking and symptoms.
Sacramento, CaliforniaAges 18–47 - NCT04188522Recruiting
MEG study of memory after a small stroke
This study uses a special brain scan called MEG to understand how thinking and memory change after a small ischemic stroke. If you qualify, you may get scanned about 4–6 weeks after your stroke and help researchers learn what brain signals relate to recovery.
Baltimore, MarylandAges 18–100 - NCT04239079Recruiting
Study of immune-related changes in Parkinson’s and Alzheimer’s
This study looks for “autoimmune-like” (immune-system) features in brain-related diseases such as Parkinson’s and Alzheimer’s, using genetic testing and other assessments. Results may help researchers understand what drives these conditions and who might be more likely to have immune-related changes.
New York, New YorkAges 55–90 - NCT04159662Recruiting
Brain scans to study thinking in schizophrenia and depression
This study uses brain imaging to better understand how thinking works in people with schizophrenia or major depression. Your results may help researchers learn what brain patterns match different thinking and symptoms.
Ottawa, OntarioAges 18–60 - NCT04240561Recruiting
Study of hearing aid results in people with Alzheimer’s dementia
This study looks at how much hearing aid outcomes vary in older adults who have Alzheimer’s dementia or mild memory problems. It may help researchers understand what hearing aids work best and for whom.

Phoenix, ArizonaAges 18 years+ - NCT04124029Recruiting
How head injuries affect brain health
This study looks at how mild or moderate head injuries (concussions) may relate to brain conditions like chronic traumatic encephalopathy (CTE) and Alzheimer's disease. By comparing people with and without head injuries, researchers hope to learn more about what causes brain changes over time.

Study brain and movement patterns in Parkinson’s or tremor
This study looks at brain signals, thinking, and movement behaviors in people who have Parkinson’s disease or essential tremor and are being considered for deep brain stimulation (DBS) surgery. It may help researchers better understand how DBS affects the brain and day-to-day function.

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.
