Abstract

BACKGROUND: It is unclear to which degree Levodopa (L-dopa) remains effective also in the late stage of Parkinson's disease (PD) and to which degree motor fluctuations and dyskinesias remain a problem. OBJECTIVE: To assess responsiveness of motor symptomatology to L-dopa in a group of patients with late stage PD. Moreover, to investigate the extent to which motor fluctuations and dyskinesias occur. METHODS: Thirty PD patients in Hoehn and Yahr (HY) stages IV and V in "on" were included. L-dopa responsiveness was assessed with a standardized L-dopa test in the defined "off" and defined "on" states. Motor function was assessed by the Unified PD Rating Scale (UPDRS) III and timed tests. Motor f..
