title: [Paroxysmal EEG disorders in various forms of schizophrenia among children and adolescents].
abstract: 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.
