Axial Signs and Magnetic Resonance Imaging Correlates in Parkinson's Disease
Canadian Journal of Neurological Sciences
Background:Age-related brain changes may contribute to axial features in Parkinson's disease (PD).Objectives:To determine if ventricular volume and white matter high signal changes (WMC) are related to motor signs in PD and controls independent of age.Methods:Patients were rated with the Unified Parkinson's Disease Rating Scale (subscore A: tremor, rigidity, bradykinesia, and facial expression; subscore B: speech and axial impairment). Steps and time taken to walk 9.144 meters were measured.doi:10.1017/s0317167100005795 fatcat:oilplwidnbbkpbfiv2xbs2csry
