[Does dissociative schizophrenia exist?]

On a phenomenological level, there's an important overlap between dissociative and psychotic symptoms. Furthermore, traumatic etiology, recognized in dissociative disorders, is also increasingly considered in psychosis. These similarities create confusion in clinical settings with important repercussions for individuals suffering from these disorders. Indeed, difficulties encountered in differential diagnoses could result in an erroneous diagnosis or in an undetected comorbidity. Some authors are going further in suggesting that there is a sub-type of schizophrenia having dissociation behind the expression of psychotic symptoms.
