[The relationship of the electrical reactions of the brain to lipid peroxidation processes in pathological aging].
The content of breathing air pentane as in vivo index of lipid peroxidation and electrophysiological parameters (visual evoked potentials and direct current (DC) potential level) of healthy volunteers and patients with senile dementia and Alzheimer's disease following weak stress sound influence were investigated. Unlike healthy subjects correlation between stress-induced changes of pentane level and electrophysiological parameters for patients with psychopathology was shown.
