[Dynamics and pathogenesis of alterations in the bioelectrical activity of the brain following pneumoencephalography].
In 40 patients with remote sequalae of closed brain injury the authors studied the brain bioelectric activity before and following pneumoencephalography in dynamics. Changes in the EEG after PEG were seen in all cases in the form of decreased alpha-activity and a significant increase in the index of slow theta and delta waves. The dynamics in the EEG changes did not depend upon the clinical syndrome and were the same in patients with epileptical seizures, as well as in patients with posttraumatic syndrome. The EEG changes following PEG were transitory and were usually combined with distinct disturbances of metabolic-vegetative functions. This permits to allocate a certain place in the pathogenesis of detected EEG changes to the action of the air and x-ray on the brain membranes, as well as on the reticular structure, hypothalamic centers of metabolic-vegetative functions.
