[Development of nosological conceptions of child psychoses].

A study of the historical development of nosological conceptions of schizophrenia of children in parallel with the development of pedopsychiatry shows that these conceptions closely follow the lines of adult psychiatry. The description of psychosis-like conditions such as infantile dementia and autism also did not yet lead to a fundamental change in pathogenetic conceptions. There is then described the heuristic approach to considering schizophrenia of children and schizophrenia-like pictures of childhood as a disturbance of adaptation to reality, the development of which can be due to dispositional factors, minimal cerebral lesions acquired in early childhood, and environmental conditions in the sense of a constellatory genesis.
