Encephalitis may present with seizures or status epilepticus, and the etiology is usually
presumed. Specific antibodies to ion channels, receptors, and other synaptic proteins were
identified during the past decade. However, only a few studies investigated antiglutamic acid
decarboxylase antibodies and antibodies to cell membrane ion channels or surface
antigens in pediatric encephalitis and status epilepticus. We examined antibodies to
glutamic acid decarboxylase and cell membrane ion channels or surface antigens in acute …
