Laser Evoked Potentials in Early and Presymptomatic Huntington’s Disease

Table 1

Demographic and clinical data in normal subjects (N), Huntington’s disease (HD) patients, and presymptomatic Huntington’s disease (PHD) patients. The ANOVA analysis shows that age was different among groups. TFC score: total functional capacity score; UHDRS: Unified Huntington’s Disease Rating Scale; MMSE: Mini-Mental State Examination. The CAG range is reported. For time from or before illness onset, the range is reported in parentheses. In PHD, negative values indicate the supposed years before clinical HD diagnosis.

	Age	Sex	CAG	Illness onset (years)	UHDRS motor section	TFC score	MMSE	Chronic pain (number)
N	42 ± 16.35	34 F; 30 M
HD	54 ± 11.50	20 F; 22 M	39–56	3.23 ± 2.11 (1,5)	32.93 ± 18.97	8.92 ± 3.33	27.1 ± 1.8	3; (mixed pain (2) and fibromyalgia syndrome (1))
PHD	36.62 ± 8.61	5 F; 5 M	39–51	−12.20 ± 9.6; (−1, −21)	4.1 ± 4.33	13 ± 0	29.9 ± 0.31	0
	ANOVA	Chi square: 0.99 ns
