[Reflection of stable dominant states in the EEG of schizophrenic and alcoholic patients]

EEG was used to study stable dominant states in 12 patients with sluggish forms of schizophrenia and 11 alcoholics. The control group consisted of 15 normals. The patients demonstrated the following traits : deviations in the EEG readings, reflecting the interaction of different cortical zones; a complex of signs indicative of changes in the development of a generalized, nonspecific component of the activation reaction compared to data of the control group; a certain rigidity in the dominant-subdominant relationships. In reduction of the pathological symptomatology and under the impact of unloading, dietic therapy (hunger) there were positive changes in the parameters characterizing the reaction of activators as well as differences in the EEG-correlations of 2 selected types of dominant states.
