Abstract

Reflex epilepsy describes seizures which are precipitated by clearly recognized stimuli. Reflex epileptic seizures triggered by tooth brushing are rare. We report a case with reflex epilepsy occurring exclusively during tooth brushing. He began having seizures at age 28. Neurological examinations and brain magnetic resonance images were found normal. On long term video-EEG monitoring, he presented two episodes of simple partial seizure induced by brushing molar and premolar teeth, which was right facial clonic movement persisting 3-5 seconds. He was unresponsive during the event, but had no postictal confusion. Ictal EEG showed 6 Hz rhythmic theta activity in the left frontocentral area. Interictal EEG was normal. The findings of EEG suggest that this reflex epilepsy might have epileptic focus in the left frontocentral area. Reasonable precaution such as gargling or less vigorous brushing of his teeth with fingers effectively prevented seizure recurrence.
