Prolactin changes after seizures classified by EEG monitoring

Abstract

We examined the postictal hyperprolactinemia after seizures classified by EEG and video telemetry. Prolactin did rise after complex partial seizures that involved motor behaviors and was not further increased by secondary generalization. Nontemporal partial seizures or pseudoseizures did not demonstrate this increase. There was no difference in prolactin elevation after generalized tonic-clonic seizures, whether secondarily generalized or generalized from onset. A discriminant function accurately classified 94% of patients with pseudoseizures and 66% of patients with true cerebral seizures for an overall classification accuracy of 72%.
