This presentation explores the benefits of implementing use of Event Related Potentials (ERPs) to assess the refugee clients with trauma related complex and chronic symptoms. Preliminary data identifying dysfunctional brain patterns underlying Post-Traumatic Stress symptoms and data supporting the effectiveness of neurofeedback interventions aimed to alter these dysfunctional patterns is presented. In addition, case vignettes are used to illustrate how an ongoing data analysis can help us evaluate the outcomes of our interventions and contribute to the improvement in our clinical services.
