The management approaches to dyskinesia vary from country to country

Abstract

Many Parkinson's disease (PD) patients treated with levodopa develop motor fluctuations and/or dyskinesia. This large, retrospective study was conducted to compare the prevalence and treatment of dyskinesia in PD patients in seven countries. A total of 380 physicians were interviewed and completed patient record forms retrospectively for their last 5 patients with dyskinesia (total 1,900). The overall prevalence of dyskinesia in PD patients was 34%, but the rate varied from 24 to 51% according to geographical location. This study showed that 51.0% of Japanese physicians and 50.6% of UK physicians were dissatisfied with current treatment strategies for dyskinesia. Regardless of geographical location, physicians were dissatisfied with the current treatment strategies for dyskinesia.
