Brain training with neurofeedback after a stroke
This study tests a brain-training technique called neurofeedback to see if it can improve thinking skills after a stroke. If you have ongoing memory or attention problems despite recovery, this trial may help you train your brain using real-time feedback from your own brain activity.
BordeauxAges 18–75 - NCT07130669RecruitingPhase 1/Phase 2
Memory and thinking study for older adults
This trial tests a program to help maintain or improve memory and thinking skills in older adults. You may join if you are 60-89, speak English, and live at home or in an assisted-living facility.
Palo Alto, CaliforniaAges 60–89 - NCT07547319Recruiting
Accelerated rTMS to improve cognitive function
This study tests whether repeated magnetic pulses to the brain (called rTMS) can help improve thinking and memory in older adults with mild to moderate cognitive decline. The treatment is non-invasive and may help slow cognitive changes.
San Francisco, CaliforniaAges 50–90 - NCT05114876Recruiting
Tested a new plan to support older adults after surgery
This study looks at a redesigned surgical care plan to better support older adults who may have memory or thinking changes after major planned surgery. If you qualify, you would be assessed before surgery and followed after to see whether this approach helps.
Toronto, OntarioAges 60 years+ - NCT07680517Recruiting
Short PTSD treatment for military personnel
This study tests if a short, intensive PTSD treatment can help reduce psychological and cognitive symptoms. It is for current military personnel with PTSD or symptoms that are close to meeting the full diagnosis.
Fayetteville, North CarolinaAges 18 years+ - NCT05968703Recruiting
Deep brain stimulation study for mild memory trouble in Parkinson’s
This trial looks at a specific type of deep brain stimulation (DBS) to see if it can help people with Parkinson’s who have mild cognitive problems (mild memory/thinking changes). You may also be asked to temporarily stop Parkinson’s medications around research visits to measure effects more clearly.
Stanford, CaliforniaAges 21–80 - NCT07193277RecruitingPhase 4
Butylphthalide for thinking problems in older adults with epilepsy
This study tests whether a medicine called butylphthalide can help improve memory and thinking in older adults with focal epilepsy who already have mild cognitive issues. It aims to find a new way to support brain health in people with epilepsy.
Wenzhou, ZhejiangAges 60–85 - NCT07402356Recruiting
Virtual reality eye test for thinking problems
This study uses virtual reality and eye-tracking (pupillometry) to measure thinking and memory problems in people with Alzheimer's, mild cognitive impairment, or depression. It aims to find better ways to detect and track cognitive changes using a simple, non-invasive procedure.
München, BavariaAges 18–80 - NCT03954899Recruiting
Melatonin test for brain health in older adults
This study tests whether taking 5 mg of melatonin can improve thinking and brain health over time in older adults with early, mild symptoms. You may help researchers learn which brain changes and measures improve with melatonin.
Iowa City, IowaAges 56–85 - NCT06095297Recruiting
Cognitive rehab for brain fog from long COVID
This study tests a computer-based cognitive training program combined with a gentle nerve stimulation device to see if it can improve brain fog and daily functioning in people with long COVID. If you're struggling with thinking, memory, or concentration after COVID, this might help.
Birmingham, AlabamaAges 18 years+ - NCT04153838Enrolling by invitation

Study of thinking changes in older adults
This trial looks at people over age 50 who have mild thinking or memory problems but do not have dementia by standard clinical criteria. It tests how these early changes are characterized and measured using exams such as blood tests and brain scans, which may help improve understanding and future care.

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.
