Document Summary
The dsm-iv-tr diagnosis the us concept of s shifted from broad def to a def that narrows the range of patients diagnosed as s in 5 ways: 1) the diagnostic criteria are presented in explicit and considerable detail. 2) patients with symptoms of a mood disorder are specifically excluded. Scizoaffective disorder comprises a mixture of symp of s and mood disorders. 3) dsm-iv-tr requires at least 6 months of disturbances for the diagnosis. Problems during the prodormal and residual phases include social withdrawal, impaired role functioning, blunted or inappropriate affect, lack of initiative, vague and circumstantial speech, impairment in hygiene and grooming, odd beliefs or magical thinking and unusual perceptual experiences. These criteria eliminate patients who have a brief psychotic episode which is often stress related and then recover quickly. The symp of s dis are the same as those of s but last only from one to six months.
