title: The effect of lamotrigine on the EEGs of children and adolescents with epilepsy.
abstract: Lamotrigine (LTG) is one of the newer-generation antiepileptic drugs (AEDs) with broad-spectrum efficacy against a variety of seizures and epileptic syndromes. We retrospectively evaluated the effects of LTG as add-on therapy on EEGs of children and adolescents. The EEGs of 53 patients (mean age: 12.5 years) with primarily pharmacoresistant epilepsy were reviewed prior to and after LTG add-on therapy. Multiple seizure types were seen in 25, generalized seizures in 15, and complex partial seizures in 13 of the patients. Preceding LTG therapy, the baseline EEG was abnormal because of slow background in 60.3% and localized spikes in 35.8%, generalized spikes in 28.3%, or both in 24.5%. The EEG analysis during the 2-year follow-up period showed improvement in the background in 21.9%, interictal activity in 37.8%, and ictal pattern in 41.1% of the EEG recordings. Overall, LTG resulted in improvement in electrographic features which paralleled the clinical improvement.
