[Changes to Schizophrenia Spectrum and other psychotic disorders in DSM-5].
This article provides an overview of the main changes in the chapter "Schizophrenia Spectrum and Other Psychotic Disorders" from DSM-IV-TR to DSM-5, which, once again, does not make allowance for potential characteristics of children and adolescents. Changes in the main text include abandoning the classical subtypes of Schizophrenia as well as of the special significance of Schneider's first-rank symptoms, resulting in the general requirement of two key features (one having to be a positive symptom) in the definition of Schizophrenia and the allowance for bizarre contents in Delusional Disorders. Further introduced are the diagnosis of a delusional obsessive-compulsive/body dysmorphic disorder exclusively as Obsessive-Compulsive Disorder, the specification of affective episodes in Schizoaffective Disorder, and the formulation of a distinct subchapter "Catatonia" for the assessment of catatonic features in the context of several disorders. In Section III (Emerging Measures and Models) there is a recommendation for a dimensional description of psychoses. A likely source of confusion lies in the double introduction of an "Attenuated Psychosis Syndrome." On the one hand, a vague description is provided among "Other Specified Schizophrenia Spectrum and Other Psychotic Disorders" in the main text; on the other hand, there is a precise definition in Section III as a "Condition for Further Study." There is some cause to worry that this vague introduction of the attenuated psychosis syndrome in the main text might indeed open the floodgates to an overdiagnosis of subthreshold psychotic symptoms and their early pharmacological treatment.
