Psychiatric Disorders Share Common Neural Circuit, Emotion Processing Dysfunction

Publication date: Feb 06, 2020

A common pattern of aberrant brain activation during emotional processing may contribute to the pathophysiology of psychiatric disorders, according to a meta-analysis published in the American Journal of Psychiatry.

The results of the study point to the validity of the Research Domain Criteria initiative and suggest that neuroimaging findings may not be specific to certain psychiatric disorders.

Lisa M. McTeague, PhD, of the department of psychiatry and behavioral sciences at the Medical University of South Carolina, Charleston, and colleagues searched PubMed for whole-brain functional neuroimaging studies comparing activation during emotional processing tasks in patients with psychiatric disorders and healthy controls.

Nonetheless, the findings of the study point to coordinated network disruptions that affect adaptive emotional expression and regulation and these networks may prove to be effective targets for therapeutic interventions.
