[Quantitative EEG in depression (author's transl)].
Evaluation of the treatment in clinical psychiatry is mostly based on the rating of mental symptoms prior and after treatment. There is an obvious need to supplement clinical observations by objective measurements. Based on EEG automatic analysis, three methods which appeared to be valuable in investigating patients with affective psychosis, are briefly reviewed. 1) The EEG drug profile, indicating changes of the EEG frequency pattern, which varies proportionally to the psychoactive properties of the drug and its metabolites. 2) The fluctuations of the vigilance level which monitor the sedative/excitatory effect of drugs. 3) The interhemispheral assymetry which is related to the intensity of depression.
