Abstract

Attentional, executive, and memory deficits have been described in PTSD, as well as emotional cognitive biases. Many findings, however, are controversial and conflicting. Here, we describe strategies for outlining a cognitive profile in PTSD. Though difficult to carry out, longitudinal and monozygotic twin studies are the best designs for measuring the cognitive effects of stress, trauma, and PTSD. Cross-sectional studies may have their reliability improved by the comparison of three groups: trauma victims who developed PTSD, trauma victims without PTSD, and healthy controls not exposed to trauma. Studies should also be homogeneous regarding type of trauma and neuropsychological instruments.
