Abstract

The Comorbidity of Psychotic Symptoms and Posttraumatic Stress Disorder: Evidence for a Specifier in DSM-5

Author(s): Julia Vigna Bosson, , Erin T. Reuther, , Alex S. Cohen

The comorbidity of posttraumatic stress disorder (PTSD) and psychotic symptoms is higher than what might be expected based on the prevalence of either disorder alone. Furthermore, the presence of psychotic symptoms is evident in PTSD patients who do not otherwise meet criteria for a psychotic spectrum disorder. The current paper discusses three existing hypotheses regarding the relation of PTSD and psychosis and presents a series of case studies that illustrates this phenomenon across a diverse group of patients and scenarios. Clinical implications in light of these case studies are offered, including the suggestion that the next edition of the Diagnostic and Statistical Manual of Mental Disorders includes a specifier of PTSD with psychotic features.
