This study tests a vaccine called AADvac1, which targets tau tangles in the brain, a hallmark of Alzheimer's. It will be given alone or with another drug (donanemab) to 450 adults aged 50-80 with very early Alzheimer's. The goal is to see if this approach can reduce tau buildup a…

This study investigates whether intensively lowering systolic blood pressure with FDA-approved medications can reduce the buildup of amyloid and tau proteins in the brain—hallmarks of Alzheimer's disease. The trial enrolls adults aged 60-85 with high blood pressure who are cognit…

This early-stage trial tests a gene therapy called PBFT02 for frontotemporal dementia (FTD) in people with specific genetic mutations. The therapy delivers a working copy of the GRN gene directly into the brain. The study involves 30 adults and primarily checks for safety and sid…

This study looks at whether online community support and telemedicine can improve quality of life for people with Parkinson's disease, Lewy body dementia, and related conditions, as well as their caregivers. About 632 participants will receive palliative care training for their d…

This study is testing a device called MemorEM, which is a cap that sends low-level electromagnetic waves to the head. The goal is to get feedback from 1,000 patients with neurological diseases like Alzheimer's or Parkinson's, and their caregivers, on how easy the device is to use…

This study follows 1,500 volunteers with normal memory, mild cognitive impairment, or Alzheimer's over several years. Researchers use brain scans, memory tests, and blood samples to track how the disease progresses. The goal is to find better ways to diagnose and treat Alzheimer'…

This study aims to find early markers of Parkinson's disease, multiple system atrophy, and Lewy body dementia by analyzing samples from the nose, blood, and urine. Researchers will compare results from 180 people with these conditions and healthy volunteers. The goal is to improv…

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 follows 850 people aged 40-64 with early-onset cognitive impairment to understand how Alzheimer's disease progresses. Participants undergo cognitive tests, brain scans, and genetic analysis, but no experimental treatment is given. The goal is to gather data that could …

This study examines walking patterns in people with Parkinson's disease and similar neurological conditions, as well as healthy volunteers. Researchers aim to identify unique 'gait signatures'—speed-dependent measures of walking—that could help distinguish between different disor…

This study looks at how adults at risk for Alzheimer's disease react after learning their amyloid and tau biomarker test results. Researchers will track changes in distress, stigma, quality of life, and future planning over time. The goal is to understand the psychological and be…

This study uses a radioactive tracer called [18F]MK-6240 to take detailed pictures of tau protein clumps in the brain, a hallmark of Alzheimer's disease. Researchers will scan 200 people from families with a rare genetic form of Alzheimer's to see how tau buildup changes over tim…

This study aims to create more sensitive cognitive tests for Huntington's disease by combining brain imaging (PET and MRI) with blood markers. Researchers will study 90 participants—healthy controls, pre-symptomatic gene carriers, and early-stage patients—to understand how brain …

This study is testing whether wearable sensors can reliably monitor movement problems in people with progressive supranuclear palsy (PSP) and related frontotemporal disorders. About 60 participants will wear pendant-like devices for 12 months to track their activity. The goal is …

This study looks at brain tissue and lab-grown nerve cells from people with schizophrenia, depression, bipolar disorder, frontotemporal dementia, and Alzheimer's. Researchers want to find out how problems with synapses—the connections between brain cells—differ in these condition…

This study aims to learn more about diseases that affect the brain, such as Parkinson's disease and different types of dementia. Researchers will follow 500 adults with symptoms of these conditions over time, using brain scans and genetic tests to see how the diseases progress. T…
