Computed tomography of the brain in children with minor neurodevelopmental disorders.

Eighty-nine boys and twenty girls with minor neurodevelopmental disorders underwent cranial computed tomography (CT). Twenty-five per cent showed aberrations at CT. The incidence of manifest lefthandedness and of developmental language disorders was not higher among children with pathological CT findings than among those with normal ones. Nineteen per cent of the children with pathological CT results but only 1% of those with normal CT findings had had afebrile seizures. Abnormal chromatographic patterns of peptides and protein associated peptide complexes in the urine were found significantly more often in children with pathological than in those with normal CT.
