Table 1.

Mean, SD, and range for demographic, cognitive, functional and motor variables for total sample (n=84).

	Mean	SD	Range
Age (Yrs)	45.4	11.0	20.3–67.7
Education (Yrs)	13.6	2.7	6–20
Mattis DRS	126.4	14.0	82–144
UHDRS FIS	76.0	14.5	50–100
UHDRS TFC	7.5	3.5	1–13
UHDRS Total Motor Score	33.3	22.2	0–83

SD = Standard Deviation

DRS = Dementia Rating Scale (possible range 0 –144)

UHDRS = Unified Huntington's Disease Rating Scale

FIS = Functional Independence Scale (possible range 0 to 100)

TFC = Total Functional Capacity (possible range 1 to 13)

Possible range of UHDRS total motor scores = 0 to 124
