Catamenial epilepsy: A missed cause of refractory seizure in young women

Catamenial epilepsy refers to changes in the frequency of seizures over the course of the menstrual cycle. A thorough history and detailed review of the patient’s seizure diary are imperative to classify the seizures accurately and select the most appropriate antiepileptic treatment. As catamenial epilepsy rarely responds to antiepileptic medications, the physician should regularly revise the treatment plan of the women with epilepsy that is refractory to the current treatment. We describe the case of a 34-year-old single woman who presented with refractory seizures.
