Test-retest reliability of saccadic measures in subjects at risk for Huntington disease.

Abstract

PURPOSE Abnormalities in saccades appear to be sensitive and specific biomarkers in the prediagnostic stages of Huntington disease (HD). The goal of this study was to evaluate test-retest reliability of saccadic measures in prediagnostic carriers of the HD gene expansion (PDHD) and normal controls (NC). METHODS The study sample included 9 PDHD and 12 NC… (More)
