Abstract

TRACK-HD was a prospective observational biomarker study in participants with premanifest and early Huntington’s disease (HD). Track-HD assessed longitudinal data collected at baseline, 12 months, 24 and 36 months at sites in Leiden (Netherlands), London (UK), Paris (France), and Vancouver (Canada). Participants were individuals without HD but carrying the mutant HTT gene (ie, premanifest HD), patients with early HD, and healthy control individuals matched by age and sex to the combined HD groups. Data were collected with 3T MRI, clinical, cognitive, quantitative motor, oculomotor, and neuropsychiatric assessments. TrackOn-HD followed on from TRACK-HD aiming to investigate compensatory mechanisms in premanifest gene carriers. Baseline, 12 and 24 month data was collected from the same four sites on premanifest gene carriers and healthy controls including 3T MRI, task and resting state fMRI, DTI, clinical, cognitive, quantitative motor and neuropsychiatric assessments.
