Ventricular dilation, cortical atrophy, and neuropsychological outcome following traumatic brain injury
CV Anderson and ED Bigler
Department of Psychology, Brigham Young University, Provo, Utah, USA.
Day-of-injury computed tomographic scans were compared with postinjury
magnetic resonance imaging of 38 patients with traumatic brain injury.
Ventricles and several white and gray matter structures were measured.
Results demonstrated significant changes in ventricular sizes and all
measures of white matter. Changes in gray matter were nonsignificant,
except in the putamen/globus pallidus. Patients were grouped according to
ventricular change, and neuropsychological outcome was examined. The group
with the highest ventricular change had significantly lower memory scores
but did not show significant differences on tests of intellectual
functioning. A three-dimensional image analysis was performed to enhance
visualization of the injured brain.
