To date, no studies are available on the effect of pregabalin in dystonia. A patient with subarachnoidal and cerebral hemorrhage was treated with pregabalin for neuropathic pain. Upon withdrawal of the medication she experienced spontaneous and painful supination in the right foot and internal hip rotation when standing up. When pregabalin was reinstituted, these dystonic symptoms subsided, but reappeared when the medication was again discontinued. One possible explanation for these symptoms could be neuronal hyperactivity within still-functioning pathways in connection with the motor cortex. Preponderance of activity in potentially compensatory structures could be suppressed by pregabalin: therefore, its potential benefit in subacute secondary dystonia in cases with orbital brain involvement is suggested.
