Our Story
This is a brain imaging study for participants ages 6-30 and living at-risk for Huntington’s Disease. “At-risk” means having a parent or grandparent diagnosed with HD. Our study uses special tests to measure thinking and memory skills, general behavior, balance and coordination. We also use a brain scan called an MRI to take a picture of the brain. Participation takes about 6-8 hours.
