Meta-analytic review of event-related potential studies in post-traumatic stress disorder


Karl, Anke; Malta, Loretta S; Maercker, Andreas (2006). Meta-analytic review of event-related potential studies in post-traumatic stress disorder. Biological Psychology, 71(2):123-47.

Abstract

In recent years there has been an accumulation of studies that have utilized the measurement of event-related potentials (ERP) to examine the neuroelectric correlates of hypothesized alterations in information processing in persons with post-traumatic stress disorder (PTSD). The objective of this meta-analysis was to summarize the findings of ERP PTSD research, including studies that have examined P50 auditory sensory gating, augmenting-reducing P200, and P300 in target detection oddball tasks. The results suggest that persons with PTSD exhibit alterations in the amplitude and latency of ERP within these paradigms that support the hypothesis that changes in information processing can accompany PTSD. The results were also consistent with recent cognitive neuropsychological findings in PTSD research.
