Objective: The goal of this study is to describe the clinical, paraclinical and evolutive features of patients having suffered a movement disorder in the aftermath of an ischemic stroke.

Background: Movement disorder following stroke represent an uncommon situation. It has been suggested that the prevalence of this complication varies from 1 to 5 % in different studies. It represents an interesting condition because of the pathophysiological questions it raises.

Methods: Authors report a retrospective study from January 2000 to December 2009. This study collected 442 stroke cases. Data were collected 442 patient’s folders who were hospitalized for ischemic stroke in the Neurology Department, Mohammed VI university hospital in Marrakesh, Morocco. Our department is a third level structure which covers much of southern Morocco. The diagnosis of ischemic stroke was established in base of clinical and CT scan criteria. Only patients who presented with a movement disorder in the aftermath of stroke were included.

Results: Within our 442 stroke patients with ischemic stroke, 18 presented a movement disorder. There was 10 man and 8 women. The mean age was 59 years. Patients presented this complication 3 days to 1 year after the acute episode. We had 8 patients who developed a parkinsonism syndrome, 4 patients had a chorea, 3 others had an isolated tremor and 3 presented a dystonia. Parkinsonism was the later to develop in our patients whereas chorea developed whiting days after the stroke. CT scan showed a subcortical ischemic stroke interesting the basal ganglia in all cases. Finally, the evolution was marked by a resolution of all cases of dystonia and chorea, in the other hand patients who had a parkinsonism were being followed in our department for up to 6 years without any major improvement.

Conclusions: The present series report the clinical, paraclinical and the outcomes of patients who presented a movement disorder after an ischemic stroke. Even with the small number of patients in this study, many finding and suggestions may be developed.
