The HD Young Adult Study (HD-YAS) is an important and exciting study designed to find the earliest time point at which any HD-related changes can be found in young-adult gene carriers, and therefore, the earliest time at which therapeutic intervention could be given to prevent HD-related changes and decline. Professor Tabrizi presented the results of this study at CHDI's Annual Conference in February 2020. You can listen to this presentation and view the slides on the CHDI Foundation website.
