Studies indicate that a high incidence of comorbidity between posttraumatic stress disorder (PTSD) and psychotic disorders. Although the case reports about this topic are more relevant, there are very few studies with large trials in terms of clinic of these patients. Clinical characteristics of case series who diagnosed PTSD comorbid psychotic disorders were aimed to discuss. Ten PTSD patients with comorbid psychotic disorders were examined. Trauma of all of the cases was caused by armed conşict. Seven patients had symptoms of paranoid delusions. All of the patients showed positive psychotic symptoms. Psychotic symptoms of five patients had begun 6 months-1 year later from the diagnosis of PTSD. Psychotic symptoms of four patients decreased with ECT and four patients had responded to risperidone. Half of the patients exhibited behavioral disorders in the form of self-mutilation. Trauma contents of all cases were about armed conşict. Considering the general characteristics of the patients, it can be seen that positive psychotic symptoms were prominent in the cases, the symptoms began approximately 1 year after the trauma (15 days-9 years), cases benefit from especially ECT and all cases had behavioral pathologies. It had been reported that 20-40% of combat related PTSD patients had psychotic symptoms. This prevalence is not as high in non-combat related PTSD patients. Successful results have been reported about using of ECT in PTSD comorbid psychotic disorders in the literature.
