Objective: Aberrant glutamate and γ-aminobutyric acid (GABA) neurotransmission contribute to seizure generation and the epileptic state. However, whether levels of these neurochemicals are abnormal in epileptic patients is unknown. Here, we report on interictal levels of glutamate, glutamine, and GABA in epilepsy patients at seizure onset and nonepileptic sites, cortical lesions, and from patients with poorly localized neocortical epilepsies.

Methods: From 1998 through 2009, 400 consecutive patients with OPC who underwent chemoradiation were included. Of these, 325 had a pPEG and 75 did not (nPEG).
