Ohtahara syndrome progressing to West syndrome

Abstract

West syndrome is a severe epilepsy syndrome composed of the triad of infantile spasms, hypsarrhythmia on electroencephalography (EEG) and mental retardation. It is sometimes due to the progression of a rare and fatal condition called early infantile epileptic encephalopathy (Ohtahara syndrome). Here we describe the case of a 3 year old male, who is a known case of West syndrome, presenting with recurrent breakthrough convulsions.
