Demographic features and clinical significance of subclassification by BSP in parkinsonism

BSP: blepharospasm, R-BSP: reflex blepharospasm, Pre-BSP: preceding blepharospasm prior to parkinsonism, BSP+AEO: blepharospasm with apraxia of eyelid opening, UPDRS: Unified Parkinson's Disease Rating Scale, IPD: idiopathic Parkinson's disease, PSP: progressive supranuclear palsy, MSA: multiple system atrophy, MSA-P: MSA parkinsonism predominant, MSA-C: MSA cerebellar predominant. ^apart III of UPDRS. Data represent mean±SEM. ^bP<0.05 by Chi-square test (compared atypical parkinsonism with IPD).
