[Variants of movement disorders within the psychopathologic structure of borderline neuropsychiatric diseases in young children].

On the basis of the examination covering 30 young children (aged 2 months to 3.5 years), three variants of motor psychogenic disorders were specified. Group I included elementary, stereotypic motor phenomena expressed as special poses, rocking, jack-knifing, finger sucking and other stereotypes of motor acts. Group II was characterized by more complicated motor and psychomotor disorders in the form of various manifestations of motor infantilism. Group III comprised children with neurotic motor monosymptomatic and ritual-behavioural obsessive actions. The above disorders are assessed from the evolutional-dynamic point of view.
