Name
Early infantile epileptic encephalopathy;
Ohtahara syndrome
Description
Early infantile epileptic encephalopathy (EIEE), also known as Ohtahara syndrome,is characterized by frequent tonic spasms of early onset within a few months of life, and a suppression-burst pattern in electroencephalography (EEG). Many causes have been considered for EIEE. It has been reported that 75% of the cases subsequently evolve to West syndrome, and later a much smaller number progress to Lennox-Gastaut syndrome.
