[Development of children with a high degree of risk of organic mental disorders (organic brain injuries at birth)].

The authors discuss the aftereffects of brain injuries in infancy and the relationships of these aftereffects with the social environment of a child. Examinations of the intellectual development and motoricity, carried out in 50 children, have revealed the most drastic delay of the intellectual and motor development in the children with clinically manifest injuries, living in socially unfavourable conditions. A favourable social environment promotes a compensation of benign injuries of the brain.
