Utility of electroencephalography in the evaluation of sleep disorders
The electroencephalogram (EEG) consists in the simultaneous recording in many channels in the scalp of the cortical-subcortical electric brain activity, spontaneous or evoked by means of surface electrodes. EEG is an electro-physiological tool used in the neurological, psychiatric, and in sleep medi...

| Summary: | The electroencephalogram (EEG) consists in the simultaneous recording in many channels in the scalp of the cortical-subcortical electric brain activity, spontaneous or evoked by means of surface electrodes. EEG is an electro-physiological tool used in the neurological, psychiatric, and in sleep medicine diagnoses. EEG helps in the identification, classification, and prognosis of patients with sleep disorders (SD). In this review, we update the state of knowledge about EEG and polysomnographic techniques, and their characteristics and alterations in SDs, and in epilepsies with clinical manifestations during sleep. The review shows that EEG/polysomnography is a tool that has many important utilities for the study of SDs.
