Neuropsychological study of states of mild intellectual retardation in children

: Fifty-five children with a mild degree of intellectual retardation leading to school disadaptation have been examined, using clinical and neuropsychological methods of investigation. Depending on the underlying disorder, 2 groups of children were identified: with local cortical abnormalities and with the hyperdynamic syndrome. The question is discussed about correlation between dysfunction of definite cerebral structures and disorders of active attention, motor disinhibition, affective and intellectual disorders. The authors specify new possibilities of the differential diagnosis of mild degrees of intellectual insufficiency with the help of a clinico-neuropsychological analysis of the syndrome which makes it possible to approach medico-pedagogical correction of such states from the pathogenetic viewpoint.
