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.
