Her episodes lasted from several hours to several days and some of the more severe episodes were associated with upwards eye deviation.

At this time, she was receiving controlled-release carbamazepine (a total of 2100mg), valproic acid and clobazam in divided doses [frequency of carbamazepine not clearly stated]. On examination, she followed simple commands. None of the episodes in question were observed in the clinic. She had a wide-based gait with moderate ataxia and right spastic hemiparesis. Oculogyric crisis was suspected and the woman’s carbamazepine dosage was gradually decreased to 600mg twice daily. During 18 months of follow-up, she was asymptomatic.
