We report a 41-year-old woman with complex reflex epilepsy in which seizures

were induced exclusively by the act of tooth brushing. All the attacks occurred

with a specific sensation of sexual arousal and orgasm-like euphoria that were

followed by a period of impairment of consciousness. Ictal EEG

demonstrated two events of epileptic seizure that were provoked after tooth

brushing for 38 and 14 seconds, respectively. The interictal EEG showed

epileptiform discharges over the right anterior temporal region and interictal

single photon emission computed tomography (SPECT) scan showed relative

hypoperfusion in the uncus of right temporal lobe. Brain magnetic resonance

imaging (MRI) revealed right hippocampal atrophy. We suggest that tooth-

brushing epilepsy, especially with sexual ictal manifestations, may provide

insight into the cerebral pathophysiology at the right temporolimbic structure.
