295.60 Residual Type

The Residual Type of Schizophrenia should be used when there has been at least one episode of Schizophrenia, but the current clinical picture is without prominent positive psychotic symptoms (e.g., delusions, hallucinations, disorganized speech or behavior). There is continuing evidence of the disturbance as indicated by the presence of negative symptoms (e.g., flat affect, poverty of speech, or avolition) or two or more attenuated positive symptoms (e.g., eccentric behavior, mildly disorganized speech, or odd beliefs). If delusions or hallucinations are present, they are not prominent and are not accompanied by strong affect. The course of the Residual Type may be time limited and represent a transition between a full-blown episode and complete remission. However, it may also be continuously present for many years, with or without acute exacerbations.
