Neuropsychiatrie and Electroencephalographic Aspects in the Diagnosis of Complex Partial Seizures *

Abstract

The authors review from a psychiatric perspective some of the electroencephalographic techniques that may assist the clinician in diagnosing complex partial seizures (temporal lobe epilepsy). Routine scalp electroencephalograms may not detect temporal lobe EEG abnormalities, leading to the false impression of pseudo or hysterical seizures.

Knowledge of the advantages of a sleep recording, specialized EEG electrodes (nasopharyngeal, sphenoidal), and natural or pharmacological activation techniques will increase one's diagnostic acumen. The authors discuss the appropriate use of these methods and their relevance to psychiatry.
