Vascular dementia

This study aimed to test a drug called BAC in people with Alzheimer's disease or vascular dementia. The goal was to see if it could improve thinking and memory, and to check for side effects. However, the trial was withdrawn before any participants were enrolled, so no results ar…

This Phase 3 trial tests whether butylphthalide soft capsules can improve thinking, memory, and daily living skills in people with mild to moderate vascular dementia. About 707 participants are randomly assigned to receive either the drug or a placebo for 52 weeks. The study aims…

This study uses special brain scans (PET imaging) to measure amyloid buildup—a protein linked to Alzheimer's—in healthy older adults, people with mild memory problems, and those with dementia. Participants receive scans every 2-3 years for up to 20 years to see how amyloid change…

This study tests whether following the MIND diet for 2 to 3 years can slow cognitive decline and reduce dementia risk in people aged 55 and older who have had an ischemic stroke. The MIND diet combines elements of the Mediterranean and DASH diets, with extra emphasis on leafy gre…

This study investigates whether people with neurodegenerative diseases—like Alzheimer's, Parkinson's, or ALS—show changes in behavior, social circumstances, or health before and after their diagnosis. Researchers will compare the records of over 61,000 patients with those of matc…

This study looks at whether giving older adults (ages 60-79) personalized advice and extra support helps them follow brain-healthy habits like a Mediterranean diet, exercise, and staying socially active. Participants have mild memory concerns or are at risk for cognitive decline.…

This study tests a short guide called the 'Jumpstart Guide' to help doctors have better conversations with dementia patients and their families about healthcare goals. Over 1,800 patients and their caregivers are taking part. Researchers will compare whether those whose doctors u…

This study is creating a statewide collection of blood samples and medical information from people with various brain blood vessel diseases, such as stroke and dementia. The goal is to build a resource that scientists can use in future research to better understand and potentiall…

This study is creating a simple test to check if people with Alzheimer's or similar conditions can understand and agree to medical decisions. Researchers will work with 100-150 participants to compare the new test with existing methods and look at brain scans and blood markers. T…

This long-term study uses yearly brain scans, genetic tests, and thinking/memory assessments to track changes in nearly 1,800 people with various dementias (like Alzheimer's and vascular dementia) and over 140 healthy older adults. The goal is to better diagnose, monitor, and eve…

This study follows 600 people with and without chronic kidney disease (CKD) for up to four years to compare how often memory loss, confusion, and daily activity problems occur. Researchers will also look for risk factors that make thinking and memory worse in CKD patients. Partic…
