Quantitative Morphologic Analysis Using Magnetic Resonance Imaging of the Corpus Callosum and Lateral Ventricle in Boys with Attention Deficit Hyperactivity Disorder

펼치기

By means of retrospective quantitative neuroanatomic imaging, the authors assessed the corpus callosum and the lateral venticle in the boys with attention deficit hyperactivity disorder(ADHD). The midsagittal cross-sectional area of the corpus callosum, divided into seven regions, and the axial ventricle-brain ratio were measured from magnetic resonance images of 18 boys with ADHD and 15 comparison boys. Two anterior regions, the genu and the rostral body, were found to have significantly smaller areas in the ADHD boys. There was no significant difference in ventricle-brain ratio between ADHD and comparison boys. This finding supports the theory of abnormal frontal lobe development in ADHD.
