title: [Clinical presentations and a classification of oligophrenia psychoses in children].
abstract: The article discusses the clinical variants of psychosis in children with mental retardation. A particular group of psychotic disorders - oligophrenia psychosis, is described. A total of 28 children (19 boys) who were hospitalized in a psychiatric hospital or treated as outpatients from 1992 to 2012 were examined. The average age of the patients was 12±1.3 years. The duration of follow-up (analysis of medical records or direct clinical observation) was up to 18 years. Almost all children had mild mental retardation (only one patient had moderate mental retardation). Diagnosis corresponded to ICD-10 codes F06.07, F06.27, F06.29, F06.817 or F06.819. Mental retardation corresponded to the second code section F70 (F71 in one case). Clinical and psychopathological methods, follow-up study, statistical analysis of the data were used. Four clinical variants of oligophrenia psychoses in children were identified: 1) psychosis with amentive confusion, 2) schizophreniform psychosis, 3) verbal hallucinosis, 4) psychosis with a predominance of psychomotor agitation.
