The EEG examination is of great importance for judging brain injuries (15). EEG follow-up in the first days and weeks after the trauma are considered to be of great value (6). In cases of disturbances of consciousness, the EEG examination is as necessary as the assessment of the neurologic status is and provides additional information for classifying the state of unconsciousness and for prognosis (6, 8, 11, 13). Favorable prognostic signs which can be seen in the EEG are sleep patterns in posttraumatic coma (1, 5) and a progressive increase in EEG responses to photic stimulation (16), paroxysmal focal discharges, but without clinical manifestations (6, 17), or a burst suppression pattern signify a bad prognosis (16).
