RATE OF DIFFERENT CLINICAL PHENOTYPES OF PSYCHOTIC DEVELOPMENT RETENTION IN EARLY CHILDREN
Keywords:
delayed psychological and speech development, PRRD, clinical phenotypes, structure of PRRDAbstract
Retardation of psychological and speech development (RDPD) is characterized by clinical heterogeneity and a diverse structure of disorders, requiring a phenotype-oriented approach to diagnosis. 255 children aged 3–6 with clinically confirmed PRR were examined. A comprehensive clinical and psychological assessment was conducted, followed by phenotypic stratification. Isolated expressive form, mixed receptive-expressive type, neurodynamic variant, PRRD combined with autism spectrum disorders, and combined cognitive-speech deficit were identified. The most common variant was the mixed type. Conclusions - PRR is characterized by pronounced phenotypic variability, which justifies the need for a differentiated diagnostic and corrective approach.
