Rules for a routine electroencephalogram recording

Abstract

Electroencephalography (EEG) is the primary method for functional assessment of the brain bioelectrical activity. It is the most effective for epilepsy diagnosing, and also used for localization of the epileptogenic zone in presurgical evaluation for pharmaco-resistant epilepsy and in critical care medicine. In practice, the most common type is a 'routine' EEG, the informative value of which depends largely on the accuracy of its performance. The paper briefly outlines the rules for performing a routine EEG and lists the most common mistakes that can affect its interpretation.
