Computed tomographic brain scanning in four neuropsychiatric disorders of childhood

Published Online:https://doi.org/10.1176/ajp.142.6.731

CAT scans were performed in 66 patients with neuropsychiatric disorders of childhood (infantile autism, attention deficit disorder, Tourette's disorder, and language disorder) and a control group of 20 medical patients. Ventricular volume and brain density were determined by quantitative, computer-based methods by researchers blind to the patients' diagnoses. There were no significant differences among diagnostic groups or between neuropsychiatric patients and medical control patients in total ventricular volume, right-left ventricular volume ratio, ventricular asymmetries, ventricle-brain ratios, or brain density.
