title: [Neurophysiologic mechanisms of combat post-extreme state of health].
abstract: The effects of ecological and occupational stress (EOS) on brain neurodynamics of Soviet and Afghanistan servicemen have been studied. The investigations have been made in Afghanistan. Neurophysiological characteristics of traumatic stress and consequences of combat trauma were studied in patients wounded in Afghanistan, in the acute phase as well as since 0.5-3 years after leaving the battlefield. The combined effect of combat situation, hot climate, highlands and desert forms EOS. It does not cause an adaptation process in servicemen. EOS is characterized by changes in bioelectrical indices of brain in interhemispheric relations both as a whole and in isolated rhythm components of EEG, by activating the stress limiting system. It exhibits pathopsychological and autonomic components which remain significant during 3 years after leaving the combat conditions. The formation of a general adaptation syndrome is prevented in explosion trauma under the influence of EOS.
