title: [Activation of bioelectric activity of the brain by sleep deprivation after closed craniocerebral injuries].
abstract: The study was undertaken for establishing the practical usefulness of 24- or 48-hour sleep deprivation test for activation of bioelectric changes in electroencephalographic investigations of patients after craniocerebral injury with loss of consciusness. For clinical and EEG investigations 84 patients were qualified. The age range was mostly 20--26 years with a low standard deviation. Positive activation was obtained in 33 cases (39.3%). A correlation was found between the frequency of positive activation was obtained in 33 cases (39.3%). A correlation was found between the frequency of positive activation and the severity of past trauma. Focal temporal-lobe changes prevailed among these bioelectric changes.
