This pilot study tests whether a gentle brain stimulation device (tDCS) used at home can help with cognitive and behavioral symptoms in Huntington's disease. Sixteen adults with early to moderate Huntington's will use the device daily for 30 minutes, alternating between real and …

This pilot study is testing whether adding music therapy to standard care can reduce irritability and impulsivity in 15 people with early-stage Huntington's disease. Participants will use a digital music therapy tool over 3 months. The goal is to find a safe, non-drug way to mana…

This study tests whether a computer-based training program can help people with Huntington's disease better understand others' emotions and social cues. Twenty participants will use the program at home and come in for follow-up visits. The goal is to see if this approach is pract…

This study is testing a smartphone app called MindTrails-Movement to see if it can help reduce anxiety in people with Huntington's or Parkinson's disease. The app uses a technique called cognitive bias modification for interpretation (CBM-I) to train users to think less negativel…

This study uses special PET scans to measure inflammation in the brains of people with Alzheimer's, Parkinson's, ALS, and other neurodegenerative diseases. Researchers will compare these scans to those from healthy volunteers to see if inflammation levels differ. The goal is to d…

This study screens 360 adults with neurodegenerative disorders like ALS, frontotemporal dementia, and progressive supranuclear palsy. Researchers will use medical history, physical exams, memory tests, movement analysis, MRI scans, and other tests to find common features and diff…

This study enrolls 600 adults with Huntington disease to examine specific genetic markers (SNPs) linked to the disease. Participants provide a blood sample and answer questions about their health and medications. The goal is to better understand the genetics of Huntington disease…

This study aims to collect cerebrospinal fluid and blood samples from 2,500 people at various stages of Huntington's disease, as well as healthy volunteers. The goal is to find biological markers that can help researchers develop new treatments. Participants must be between 11 an…
