Schizophrenia is a severe and persistent mental illness that is typically associated with distress and severe functional impairment. Individuals presenting with schizophrenia have symptoms that markedly impair their ability to perceive, think, engage, or express themselves clearly. Because the diagnostic criteria for schizophrenia articulated in the DSM-IV have been shown to have clinical utility, validity, and reliability, the core of these criteria are retained in the DSM-5 (Tandon et al., 2013). The modest changes include three changes to the "Characteristic Symptoms" criteria (Criterion A). DSM-5 has also made changes to some of the descriptors involving negative symptoms associated with the diagnosis of schizophrenia. The most notable change is the discontinuation of distinguishing between four distinct subtypes of schizophrenia (disorganized, catatonic, paranoid, and undifferentiated). The prominent symptoms associated with a diagnosis of schizophrenia make it among the more reliably diagnosed psychiatric disorders (Ritsner et al., 2013). The changes made to the DSM criteria are nonetheless intended to improve the diagnostic diagnostic reliability and clinical utility of the diagnosis.
