A comparative study of the frequency of EEG paroxysmal disturbances in healthy and schizophrenic children and adolescents was carried out. The study has enabled the authors to reveal a greater occurrence of bilateral outbreaks of relatively high-amplitude slow waves in the picture of the cortical rhythms in patients with paroxysmal schizophrenia, as well as in a group of patients with psychopathy-like disorder taking the form of persistent pathological cravings. The intensification of the paroxysmal outbreaks on the EEGs of the patients with paroxysmal schizophrenia can be regarded as an indication of incidental rises of the excitability of the brain systems synchronizing the cortical rhythms, these rises creating conditions favouring the transition from one functional state of the patients to another. On the other hand, marked paroxysmal outbreaks in patients suffering from continuous schizophrenia with prevalence of psychopathic heboid-type disorders in the clinical picture can be associated with pronounced signs of retardation and distortion of the age regularities of the development.

Clinical and electroencephalographic peculiarities in monozygotic (15 pairs) and dizygotic (28 pairs) twins suffering from schizophrenia were studied. In addition to the traditional comparison of the mono- and dizygotic twins as regards the clinical and encephalographic similarities and differences in each pair of them, peculiarities of male and female pairs of the twins were also compared (in each group). A tendency to a greater variability of the characteristics examined was revealed among the female twins.

The study is concerned with the traits of brain electroactivity in 35 parents (19 mothers and 16 fathers) whose children had attack-like schizophrenia and in 65 parents (36 mothers and 29 fathers) where the process in the children had a continuous course. The results of the study demonstrated certain differences in both groups according to the frequency in the cortical rhythms of some encephalographical signs and their interconnected combinations. The traits of the EEG, indicating the existence of a tendency to some changes in the functional state of the brain in parents correlated with the indices of their clinical state.

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.

In different age groups of schizophrenic children and adolescents there is a tendency towards a drop in the amplitude of fluctuation of brain biopotentials and to a decrease in the square of modul according to the data of EEG automatic integration. In the younger age groups (3-9 years) these differences were significant. The same tendency was marked in the parients of schizophrenic children. In epileptic patients and their parents according to this sign there was an opposite direction of EEG changes.
