Subjects with PTSD had worse cognitive performance in several areas: processing speed, executive function, and learning. CNS imaging has suggested that PTSD patients demonstrate anatomical reductions in the size of the hippocampus and frontal lobes, which are involved in episodic memory, processing, and executive function. Since depression, poor health behaviors, and vascular risk factors are also associated with cognitive dysfunction, the authors encourage particular attention to these elements in PTSD patients.
