[Incidence of infantile cerebral lesions in children with behavioral disorders].

The delimitation of behavioural disturbances predominantly due to organic brain lesions from those caused by reactions due to environmental factors has practical importance for drug therapy and pedagogic guidance. Figures on the incidence of infantile brain lesions among children with behavioural disorders range from between 20 to 90%. However, comparison of the results is difficult, because different authors followed different aspects for the evaluation of their material. The authors have collected data from 497 children from the 3 to 15 year-old age group who suffer from behavioural disturbances: history, neurological and psychological findings, electroencephalogram, native x-ray picture of the skull, pneumo-encephalogram and echoencephalogram were reviewed for signs and findings suggesting infantile brain damage. Certain signs of intantile brain lesion were found in 28.6% of the children. Among the apparative diagnostic procedures without impairment to the patients, the electroencephalogram proved particularly suited for the support of the diagnosis. The most accurate data on the localization and extent of the lesion are provided by the pneumo-encephalogram. However, its performance is not possible or justified in each child.
