Lennox-Gastaut syndrome in south Iran: Electro-clinical manifestations

LGS is an uncommon epileptic encephalopathy characterized by multiple seizure types, a specific electroencephalographic pattern and psychomotor retardation, beginning in childhood. However, variants of this classical triad including atypical EEG findings, normal psychomotor function, and late-onset disease could be seen in some patients. These atypical findings in a patient with typical history for LGS should not deter from the correct diagnosis. The mainstay for making a correct syndromic diagnosis is a detailed clinical history.
