schizophrenia residual schizophrenia F20.5x 295.60 At the DSM-5, the DSM-IV subtypes of schizophrenia (i.e., paranoid, disorganized, catatonic, undifferentiated, and residual types) are eliminated due to their limited diagnostic stability, low reliability, and poor validity. These subtypes also have not been shown to exhibit distinctive patterns of treatment response or longitudinal course. (Highlights of Changes from DSM-IV-TR to DSM-5, American Psychiatric Publishing) The diagnosis of this form of schizophrenia is reserved for people who have had at least one previous schizophrenic episode but who are now showing an absence of prominent psychotic features. There is continuing evidence of two or more symptoms, such as marked social isolation, peculiar behaviours, blunted affect, odd beliefs, or unusual perceptual experiences. The disorder may be in remission. In any case, the person’s symptoms are neither strong enough nor prominent enough to warrant classification as one of the other types of schizophrenia.
