title: Computerized axial tomography in clumsy children with developmental apraxia and agnosia.
abstract: Fifty-one children who were clumsy because of perceptual disabilities and/or defects of motor organization were surveyed with computerized axial tomographic (CT) head scanning and compared to 33 controls by using both linear measurements and visual appraisal of the scans. Thirty-nine percent of these so-called clumsy children described as having developmental apraxia and agnosia, compared to 9% of the controls, were either abnormal or normal variants. These presumed abnormalities included ventricular dilatation, peripheral atrophy and parenchymal lesions. The Evans Ratio and Intercaudate Distance in the clumsy children were not significantly different from the controls, but the Ventricular Area Index was found to be very significantly different in the two groups.
