A Case of Post-stroke Rhythmic Akathisia

netic movement disorders are uncommon in acute stroke. Ghika Schmid et al. have identified 29 patients with acute or delayed movement disorders among 2500 acute stroke patients. Recently, we have experienced 34 post-stroke tremor patients among approximately 2000 acute stroke patients over a 5-year period. Our results suggested that post-stroke dyskinesia are not very rare symptoms of stroke. Furthermore, it is suspected that clinical patterns are also diverse. We have recently experienced a new form of poststroke dyskinesia which was fairly rhythmic. As far as we know, only one case of post-stroke akathisia has been reported until now. T h e symptoms and signs are partly compatible with akathisia. However, the rhythmic tendency and lack of any medication history of antipsychotics suggested that dyskinesia were not the typical form of akathisia. The present case may represent a new clinical type of movement disorder developed after stroke. Therefore, we report the case and discuss with reference to related artic l e s .
