COGNITIVE DECLINE

This study looks at whether eating 50 grams of walnuts every day for 24 weeks can improve brain function in adults aged 45-75 with abdominal obesity. Researchers will measure blood flow in the brain and how well the brain responds to insulin, as well as thinking skills and appeti…

This study tests whether eating foods high in resistant starch (a type of fiber) can slow down memory and thinking problems in people who have a high genetic risk for cognitive decline. Seventy adults aged 40 and older with obesity or large waistlines will eat either high-resista…

This study tests whether a daily lutein supplement made from microalgae can slow cognitive decline in postmenopausal women with obesity. 300 women aged 48-60 will take either 6 mg, 14 mg, or a placebo for 180 days. Researchers will measure changes in memory, attention, and inflam…

This study tests whether minocycline, an antibiotic that reduces brain inflammation, can safely prevent or reverse memory and thinking problems in adults with sickle cell disease. About 30 participants will take either a low dose, high dose, or placebo for one year. Researchers w…

This pilot study will test whether a non-invasive brain stimulation device called rTMS can improve cognitive function in adults aged 50 to 90 with mild to moderate memory problems. Eighty participants will receive six sessions of targeted magnetic pulses over three weeks. Researc…

This study tests whether a smartphone app called utmbHealthyBrain is easy for older adults and their caregivers to use. The app includes drawing, Tai-Chi, meditation, and a sharing feature to help with emotions, movement, and social connection. Forty pairs of adults aged 50+ and …

The AHEAD study is testing whether artificial intelligence can help detect early signs of Alzheimer's disease in people who feel their memory is slipping but still test normal. Researchers will use brain scans, eye tests, and blood markers to identify those at highest risk. High-…

This study looks at how short bursts of aerobic exercise affect brain function in older adults and stroke survivors. Researchers will compare three groups: one doing moderate cycling to raise lactate levels, one doing light cycling, and one receiving health education only. Partic…

This study will follow 600 people who need either bypass surgery (CABG) or a stent (PCI) to open blocked heart arteries. Researchers will test memory and thinking skills before the procedure and again at 1 month, 1 year, and 2 years after. The goal is to see if one approach leads…
