Schizophrenia dating 1 5
This new category of disorders includes Obsessive-Compulsive Disorder, Body Dysmorphic Disorder, and Hoarding Disorder (among others).These three disorders have a new specifier related to insight.Symptom criteria changes: Schizophrenia: Criterion A lists the five key symptoms of psychotic disorders: 1) delusions, 2) hallucinations, 3) disorganized speech, 4) disorganized or catatonic behavior, and 5) negative symptoms. However, only 1 of the 5 symptoms was required if delusions were bizarre or if hallucinations included a running commentary on a person's thoughts/behavior, and/or two or more voices conversing.This exception has been removed for lack of specificity and poor reliability. The notion of what constitutes “bizarre” is rather vague, and its removal reduces cultural bias.Males reach a single peak of vulnerability for developing schizophrenia between the ages of 18 and 25 years.In contrast, female vulnerability peaks twice; first between 25 and 30 years, and then again around 40 years of age. The same basic diagnoses are still available in the DSM-5.Some symptom criteria were changed to make diagnosis more accurate and precise.
It can be quite difficult to recognize schizophrenia during this early prodromal stage, particularly if it is a new diagnosis and has not occurred before for a given patient.Though the schizophrenic person may have been hearing criticizing voices and experiencing delusions for some time, these symptoms may not have been overwhelming or frightening enough to have caused them to break down and act in a bizarre manner.
