  1. No significant differences were found between Pre-HD and Controls in any of the Demographic variables
  2. IQR Interquartile Range, CAG repeats CAG repeat expansion confirmed by a genetic test, Time to HD Onset estimated number of years to the formal diagnosis of manifest HD, calculated with the Langbehn’s formula [58], UHDRS Unified Huntington’s Disease Rating Scale [59], TMS Total Motor Score of the UHDRS, OculoTMS a composite score extracted from the sum of the oculomotor items of UHDRS-Motor scale, TFC Total Functional Capacity scale of the UHDRS
