[Sulpiride induced dystonia in a patient with Tourette syndrome. A stroke-mimicking presentation].

We present a case of a 23-year-old male Caucasian patient admitted to the emergency department because of an acute onset of difficulty of articulation, weakness of the left arm, throat- and neck pain. An emergency CT & MRI of the brain showed no abnormalities. The Patient had started visiting a new neurologist three weeks before admission and received Sulpiride against Tourette syndrome (TS) in a rapid escalation manner over a short period. Sulpiride induced dystonia and other neurological symptoms that were clinically masked by dystonic and clonic tics of the known TS. 5 mg Biperiden (anticholinergic agent) was slowly injected intravenously under monitor condition. The Patient reported an immediate disappearance of articulation difficulties, left arm movement, and cervical and neck pain. After discontinuing Sulpiride the patient did not develop such attacks anymore and could be discharged the next day. This case shows the development of dystonia in correlation to the use of Sulpiride, which involved the cervical region, the laryngeal muscles, and the left upper extremity. Our case is of particular interest to neurologists and psychiatrists, because of their involvement in the treatment of TS. Therefore, young neurologists must be aware of such complications when thinking of differential diagnosis in movement disorders particularly in TS.
