title: [Specific aspects of psychoses in mentally retarded children and adolescents].
abstract: Mental retardation is a heterogenous neurodevelopmental disorder characterized by arrested or incomplete psychological development. The first part of the study deals with psychological and biological factors: etiology and pathogenesis of mental retardation and comorbid psychiatric disorders. Their etiopathogenesis is similar as in other neurodevelopmental disorders and it was analyzed in the part dealing with biological specificities of persons with mental retardation. Numerous biopsycho-social factors cause increased vulnerability of the mentally retarded to development of mental disorders. Thus, prevalence of these disorders is higher in mentally retarded persons than in general population. This study also deals with specificities regarding diagnosis of psychotic disorders in mentally retarded persons as well as neurobiologic, epidemiologic, clinical and therapeutic characteristics of schizophrenic psychoses, autism and affective disorders in persons with mental retardation. Special emphasis was given to diagnostics of these disorders in mentally retarded children and adolescents, as well as to problems of differential diagnostics. Apart from other things, we have concluded that specific clinical pictures demand subspeciality approach in the frame of developmental psychiatry.
