Note. Low/Medium/High group were generated from the CAPd scores and represent the percentage of individuals in our sample in each of the disease severity groups. Categories denote disease burden as defined by Zhang et.al, 2012. Low indicates further from motor diagnosis of HD, and Hid indicates close to motor diagnosis of HD. Motor score was created based on motor symptom cluster scores such that a higher score indicates greater symptom severity (Misiura, et. al, 2017).
