This study is testing whether a new blood test can accurately diagnose the cause of memory problems, potentially replacing the need for a spinal tap. Researchers will compare blood test results with standard spinal fluid tests in 1,200 people at a memory clinic. If successful, it…

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 daily over four we…

This study looks at how past traumatic brain injuries (TBI) may affect thinking skills and blood vessel health in military personnel and veterans. Researchers will measure substances in the blood linked to blood vessel damage, inflammation, and brain cell loss. They aim to find p…

This study aims to create a model that better predicts how different types of dementia will progress over time. Researchers will follow 500 people with early dementia or mild cognitive impairment, using blood tests and thinking assessments. The goal is to improve prognostic confi…

This study looks at 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—some with shingles and some without—by analyzing tiny particles in their blood over …

This study looks at whether certain blood markers 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 participants aged 65 and older who have lost some independence. T…

This study is testing whether simple blood tests and brain scans can help doctors in primary care detect Alzheimer's disease and other memory disorders earlier and more accurately. Researchers will recruit 1,200 adults with mild memory or thinking complaints. The goal is to impro…

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 …
