[Electroencephalographic correlates of schizophrenic type mental disorders at an early age in childhood].
Electroencephalographic study was performed in 30 children of 1-3 years old from the group with the high risk of schizophrenia. Clinical observation of the patients was performed in the period of EEG recording and follow-up study was also made during 10-12 years. Three groups of patients were picked out with the differences in both clinical and electrophysiologic indices. Bundle beta-activity was registered on EEG in the cases of an active schizophrenic process. A presence of the spindles of the sleep and their dominance on EEG were characteristic for children with nonprocessual disorders of psychopathic-like type with disinhibition of the drives. Hypersynchronism of delta- and theta-activities were observed in the cases of schizotypic diathesis and an early children's autism with the predominance of paroxysmal somato-autonomic disorders.
