A 22-year-old man is brought to the hospital because his roommate says that he has been acting very strange for the past few hours. His roommate describes the patient as previously socially active and outgoing guy whose behavior has grown to be paranoid and isolated. He has stopped attending classes, exercising, and does not seem to be eating very often. His roommate acknowledged past episodes involving the patient assumingly combating demons. Family history is significant for a sister with major depressive disorder. His temperature is 37.0°C (98.6°F), pulse is 82/min, respirations are 16/min, and blood pressure is 126/82 mm Hg. Physical examination shows the patient has a flat affect with disorganized speech. Which of the following features would lead to a diagnosis of schizoaffective disorder?

Schizoaffective disorder (abbreviated as SZA, SZD or SAD) is a mental disorder characterized by abnormal thought processes and deregulated emotions. The diagnosis is made when the patient has features of both schizophrenia and a mood disorder—either bipolar disorder or depression—but does not strictly meet diagnostic criteria for either alone. The bipolar type is distinguished by symptoms of mania, hypomania, or mixed episode; the depressive type by symptoms of depression only. Common symptoms of the disorder include hallucinations, paranoid delusions, and disorganized speech and thinking. The onset of symptoms usually begins in young adulthood, currently with an uncertain lifetime prevalence because the disorder was redefined, but DSM-IV prevalence estimates were less than 1 percent of the population, in the range of 0.5 to 0.8 percent. Diagnosis is based on observed behavior and the patient's reported experiences.
