Abstract

Event Abstract Back to Event A systematic review of comorbidity in PTSD using eye tracking and MEG Selma Music1, 2*, Susan Rossell1, 2 and Joseph Ciorciari1 1 Swinburne University of Technology , Brain and Psychological Sciences Research Centre, Australia 2 Monash Alfred Psychiatry Research Centre , Australia A review of neuroimaging and electrophysiological literature of Post-traumatic Stress Disorder (PTSD) suggests conflicting results in relation to structural, functional and electrophysiological data available to date. For instance, a widely reported finding in the PTSD literature includes amygdala hyperresponsivity (e.g. Flemingham et al., 2010; Shin et al., 2005). However, upon closer inspection of the participants in the study by Flemingham et al. (2010), for example, out of the 23 participants in the 'PTSD group', 15 met the criteria for Major Depressive Disorder (MDD), and 3 for Panic Disorder. Similar results were observed in the study by Shin et al., (2005) where within the 'PTSD group' (n=13), participants also met the criteria for MDD (n=4), dysthymia (n=2), bipolar disorder II (n=1), panic disorder (n=3), social (n=2) and specific phobia (n=1). One possible explanation for such discrepancy in findings is that "pure cases" of any psychiatric disorders, and particularly PTSD, are a minority and comorbidity is more frequently the norm. Regardless, research studies often make conclusions without considering the impact of comorbidity in the sample of participants. The present paper will systematically review neuroimaging findings and highlight the methodological limitations in the study of comorbidity in PTSD. Furthermore, it will propose a different methodological approach. This includes an attentional bias paradigm using MEG and eye tracking which controls for comorbidity in the stratification of group membership.
