ABSTRACT

Introduction: Epilepsy is a disease that affects all age groups, with a prevalence of 6-18/1,000. The incidence is higher in early infancy and after 65. Development of epilepsy in adolescence is less frequent and there are very few studies about it; in this age group predominates the idiopathic epilepsies. Material and methods: We have studied prospectively a group of 17 patients that initiated with non idiopathic epilepsy (symptomatic/cryptogenic) in adolescence. All of them were studied with CT-Scan and magnetic resonance imaging (MRI), and we compare the results of both studies. Results: The MRI showed brain lesions in six of 17 patients (35%). The most frequent pathology was hipocampal atrophy and sclerosis. Conclusions: Initiation of symptomatic or cryptogenic epilepsy in adolescence is frequent. Partial seizures predominate and MRI is a very important diagnostic tool, which must be done in all the patients in whom CT-scan fails to show the etiology.
