[Characteristics of the changes in mental activity of children with pathology of the biliary tract].

The paper treats of the data on the psychoneurological sphere in preschool children suffering from dyskinesia of the biliary tract. A study was made of the psychoneurological status of 120 schoolchildren with biliary pathology. Three variants of the +cerebro-asthenic syndrome were revealed: ++astheno-adynamic, ++astheno-hyperdynamic and moderately marked ones. To objectively evaluate the mental status and the structure of mental activity disorders, all the children underwent an experimental and psychological examination. A relationship was discovered between the changes in mental activity and the variant of the cerebrasthenic syndrome and the child's age. The most remarkable changes in mental activity were recorded in children with the ++astheno-adynamic variant of the +cerebro-asthenic syndrome.
