StrasbourgAges 32–55 - NCT04906863Recruiting
Genetic study for early dementia in adults and families
This trial studies genes to better understand why some people develop dementia and memory problems earlier in life. It may help researchers find clearer causes and improve future testing and treatments for families affected by dementia.
New York, New YorkAges 35 years+ - NCT04911738Recruiting
Virtual reality glasses to improve balance after stroke
This trial studies whether virtual reality glasses training can improve balance and body alignment after a recent stroke. It will also compare how stroke participants with balance problems respond versus people without stroke.
GrenobleAges 18–80 - NCT07699848Recruiting
Sitting actively versus passively: thinking and energy
This study compares two types of sitting to see how they affect your thinking and energy levels. It will help understand if moving while seated is better for your brain and how you feel.
Coral Gables, FloridaAges 18–70 - NCT04601038RecruitingPhase 2
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+ - NCT02604563Recruiting
Aging, blood changes, and health in older adults
This study examines why some older adults develop changes in their blood cells that may affect their health. Researchers will look for links between these blood changes, aging, and common health problems in older people.
St Louis, MissouriAges 50 years+ - NCT07051655Recruiting
Ketone drink for thinking and memory
This study tests whether a drink containing ketones (a natural energy source for the brain) can improve thinking and memory. It involves three groups: people with obesity, lean people, and athletes.
Birmingham, AlabamaAges 19–55 - NCT04946916Recruiting
Testing blood/brain marker levels and thinking problems in psychiatric illness
This study looks at neurofilament light (a brain/nerve injury marker) and how it relates to thinking and memory problems in people with certain psychiatric conditions. It may help researchers understand brain changes and cognitive impairment, which could guide better diagnosis in the future.
BronAges 45–80 - NCT04997642Recruiting
Parkinson’s patient database for memory and movement tracking
This study builds a research database of people who receive care for Parkinson’s disease, including those with mild memory problems or dementia. It aims to collect consistent information that researchers can use to better understand Parkinson’s and related thinking changes.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05002309RecruitingPhase 2
Pausing depression treatment early to see if it helps
This Phase 2 study tests whether stopping treatment early affects depression outcomes in teens and young adults. It is mainly for people recently diagnosed with depression who need treatment but can participate in psychological therapy.
Halifax, Nova ScotiaAges 12–25 - NCT05009433Recruiting
Exercise plans in pregnancy and afterward for mom and baby health
