A unique feature of electroencephalography (EEG) in patients with primary and secondary brain damage, accompanied by impaired consciousness, is the possibility of reducing the number of recording electrodes and the high frequency of occurrence of stereotypical combinations of graphoelements (special patterns). In EEG reporting in these patients, it is possible to use the special classification developed in 2013, which designates them as “rhythmic and periodic patterns” (RPP). Its implementation significantly increases the degree of inter-rater agreement, and clinical use allows not only to diagnose non-convulsive epileptic status accurately but to predict its occurrence at the preclinical stage and to assess the likelihood of recovery of consciousness in patients with coma. The review outlines the features of EEG recording in unconsciousness patients and describes the reporting methodology of rhythmic and periodic EEG patterns.
