HDClarity
HD Clarity consists of the collection of cerebrospinal fluid. The cerebrospinal fluid, if analyzed, can help to better understand the pathophysiology of HD and identify potential biomarkers of the disease. The spinal fluid is collected through a lumbar puncture and stored in a centralized biobank, which is the same as Enroll-HD (Biorep, Milan). Those who already participate in the Enroll-HD study can join the HD Clarity study.
