This early-phase trial will test whether a special form of resveratrol (JOTROL) is safe and tolerable for people with Parkinson's disease. About 30 participants will receive either a low dose, high dose, or placebo daily for three months. The study will also measure how the drug …

This study tests a home-based dual-task training program for people with Parkinson's disease who have mild cognitive impairment and are at high risk for dementia. Participants will cycle on a stationary bike while playing brain-training games on a tablet, three times a week for 3…

This observational study will enroll 440 Danish-speaking adults over 50 to see if an artificial intelligence model can detect dementia and mild cognitive impairment from speech recordings. Participants will complete standard cognitive tests and describe a picture while being reco…

This study will test whether measuring a specific abnormal protein (alpha-synuclein) in spinal fluid can reliably distinguish dementia with Lewy bodies (DLB) from Alzheimer's disease. Researchers will collect samples and perform cognitive tests on 286 older adults with suspected …

This early study tests whether a single session of focused ultrasound—using sound waves to gently stimulate a specific brain region—can safely reduce emotional symptoms like agitation, irritability, and anxiety in people with mild dementia. Fifteen participants aged 45 to 80 with…

This study tests a special helmet that shines near-infrared light on the brain (called transcranial photobiomodulation) in 40 people with Lewy body dementia. Participants use the helmet twice daily for 6 months. Researchers will check thinking skills, symptoms, and quality of lif…

This study tests whether a tailored online support group (VOCALE LBD) can reduce depression in family caregivers of people with Lewy body dementia (LBD). LBD caregivers often face high stress and depression rates. The 8-week program brings small groups together online to discuss …

This study from Stanford University will look at how people react when they learn their Lewy Body Disease biomarker test results. Researchers will interview and survey 40 participants, both with and without symptoms, to measure distress and other responses over time. The goal is …

This observational study will enroll 200 people—100 with Parkinson's disease, 50 with related conditions, and 50 healthy controls—to find molecular markers in blood, urine, and stool that can distinguish Parkinson's from atypical parkinsonism. Participants provide samples and und…

This study will follow 2,800 adults aged 55 and older in China for many years to understand how aging affects the brain and thinking skills. Researchers will collect information on diet, lifestyle, medical history, brain scans, and gut bacteria. The goal is to learn what helps pe…
