[Features of the cerebral electrical activity of parents whose children suffer schizophrenia].

A study of the brain bioelectroactivity in 107 parents (62 mothers and 45 fathers) of schizophrenic children permitted to detect in the cortical rhythms of the parents an increased frequency of the encountered signs which are significantly more often seen in the EEG of schizophrenic patients. A quantitative distrubtion of such signs and their systemic combinations appeared to be different when comparing the EEG of fathers and mothers of the patients. The achieved data may be considered as supplementary proof supporting the concept of the role of hereditary factors in the etiologh of the disease.
