We therefore sought to determine whether focal cortical or subcortical grey matter changes may be present from the early disease stage. METHODS We recruited 49(More)
The purpose of this study is to investigate whether medication and deep brain stimulation (DBS) have differential effects on the speed and amplitude of bradykinesia in patients with Parkinson's disease (PD). Five PD patients with implanted DBS electrodes (age: 60.6 ± 7.4 yrs, H&Y stage: 3.1 ± 0.2) participated in this study. FT (finger tapping) movement was(More)
BACKGROUND Atypical Parkinsonism is less common and has more severe symptoms than Parkinson's disease (PD). Little is known about the non-motor symptom (NMS) characteristics of multiple systemic atrophy (MSA) or progressive supranuclear palsy (PSP). We report the interrelationship of NMS in MSA, PSP, and PD. METHODS We studied 117 cases of PD and 57 of(More)
