Infantile epileptic encephalopathy (Ohtahara syndrome) and migrational disorder.

Author information

Department of Neurology, Montreal Children's Hospital, McGill University, Quebec, Canada.


A case of early infantile epileptic encephalopathy (EIEE) with suppression-bursts (Ohtahara syndrome) associated with a diffuse cerebral migrational and maturation disorder evident on microscopic examination is reported. Although virtually all reported cases of EIEE are secondary to a congenital or acquired structural malformation of cortical development, EIEE is sometimes identified only by detailed neuropathologic examination, as confirmed by this case report. In addition to the malformation of cortical development, the patient demonstrated an absence of gamma-aminobutyric acid in the cerebrospinal fluid. All children with EIEE should be thoroughly examined by magnetic resonance imaging, cerebrospinal fluid amino acid level determination, and detailed postmortem neuropathologic examination.
