Posttraumatic stress disorder (PTSD) is associated with decreased<br />hippocampal volume, but the relationship between trauma and brain<br />morphology in the absence of PTSD is less clear. In this study, measures<br />of brain integrity were determined by estimating gray and white matter<br />regional brain volumes using structural magnetic resonance imaging in<br />six patients with PTSD and in five controls with comparable trauma<br />exposure but without clinical evidence of PTSD. The only statistically<br />significant volume difference between groups was observed multivariately<br />in the white matter of the right temporal lobe (superior temporal gyrus,<br />fusiform gyrus, parahippocampal gyrus, white-matter stem, middle<br />temporal gyrus, and inferior temporal gyrus), although small sample<br />sizes limit the power to detect between-group differences. Both groups<br />showed heterogeneity in cerebral atrophy.
