Extensive apoptosis in a case of intractable infantile status epilepticus.

A previously healthy 8 1/2-month-old girl underwent epilepsy surgery for intractable focal seizures with secondary generalization that progressed to status epilepticus. The major neuropathologic finding was extensive apoptosis. Investigations did not reveal any etiology for the apoptosis or the seizures. This is the first report of apoptosis, without necrosis, in association with intractable status epilepticus in the developing human brain. The findings suggest that new treatment strategies targeted to prevent apoptosis may be useful in children with prolonged status epilepticus.
