An 8-Year-Old Girl of Micturition-Induced Epilepsy

Abstract

An 8-year-old girl with seizure related to micturition was reported. Her right arm dropped following urination and a clonic convulsion occurred in her right leg. Anticonvulsant therapy was started under the diagnosis of the partial seizure. No seizure could be observed during the medication of an adequate dose of carbamazepine. However, seizure appeared again after the drug was reduced. The ictal EEG revealed irregular poly-spikes and waves. During seizure, consciousness was almost retained or only slightly disturbed. No postural hypotension was observed.
The clinical manifestation of our case was not consistent with that of the micturition syncope defined by Proudfit and Forteza with respect to the type of seizure, the responsiveness to anticonvulsant therapy and the ictal EEG findings. It was concluded that our case had micturition-induced epilepsy.
