VASCULAR DEMENTIA

This study is testing a new, non-invasive eye scan that uses different colors of light to look for signs of brain diseases like Alzheimer's, Parkinson's, and dementia. Researchers will scan the eyes of 930 adults aged 30 and older, including those with these conditions and health…

This study tests a small device worn on the ear that sends gentle pulses to a nerve, aiming to improve thinking and memory in people with vascular dementia or mild cognitive impairment. Twenty-four adults aged 55 to 89 will use the device at home for 30 minutes each day over four…

This observational study looks at whether leaky blood vessels in the eye can signal similar damage in the brain, which is linked to strokes and dementia. Researchers will inject a fluorescent dye into 40 participants and take detailed eye images. The goal is to see if eye vessel …

This study looks at whether simple blood tests and brain scans can help predict which older adults with memory loss or frailty will need to visit the emergency room within six months. Researchers will follow 110 people over age 64 who have trouble with daily activities. The goal …

This study looks at how traumatic brain injury (TBI) may lead to thinking problems and blood vessel damage in the brain. Researchers will follow 300 active-duty military members and veterans, measuring blood markers and thinking skills over time. The goal is to better understand …

This study aims to better predict how dementia will progress in individuals with mild cognitive impairment or early dementia. Researchers will collect blood samples and use computer models to track changes in thinking and memory over time. The goal is to improve prognostic confid…

This study aims to help family doctors better detect early signs of Alzheimer's and other dementias. Researchers will test 1,200 adults with memory or thinking problems using simple blood tests and brain scans. The goal is to make accurate diagnosis easier and faster in primary c…

This study is testing whether new blood tests can accurately diagnose the cause of memory problems, potentially replacing the need for more invasive spinal fluid tests. Researchers will compare blood test results with spinal fluid results in 1,200 people being evaluated at a memo…

This study explores whether having shingles (herpes zoster) raises the risk of vascular dementia, a type of memory loss caused by poor blood flow to the brain. Researchers will compare 375 adults with and without shingles, analyzing tiny particles in their blood called exosomes f…
