Dual-Task Performance in GBA Parkinson’s Disease

Figure 1

(a) Dual-task performance “walking while checking boxes (X) or while subtracting serial 7s (7s).” (b) Dual-task performance “checking boxes (X) or subtracting serial 7s (7s) while walking.” A logistic regression analysis, with the motor part of the Unified Parkinson’s Disease Rating Scale and the Montreal Cognitive Assessment as covariables, including likelihood ratio was used to calculate values. Significance level was set at . GBA-PD = Parkinson’s disease patients carrying a heterozygous glucocerebrosidase mutation; iPD = idiopathic Parkinson’s disease.
