He is cooperative and well-groomed. In the course of discussing his history, he calmly mentions that the Illuminati is trying to kill him.
He is accompanied by his guardian, who states that he has held this belief for at least 5 months. The guardian asks if there isn't anything you can do about this behavior, since it has the rest of the family worried.
The patient feels well otherwise, and continues to do well in his job as a tadpole collecter.
There is no significant past medical or psychiatric history.

B) schizophrenia

This answer is incorrect.


The diagnosis of schizophrenia requires at least 6 months of continuous signs of psychological disturbance. This 6-month period must include at least 1 month of "active-phase" symptoms: delusions, halucinations, disorganized speech, grossly disorganized or catatonic behavior, or negative symptoms (affective flattening, alogia, or avolition). This patient is psychotic, in that he has delusions, but he remains funcitonal and has no other psychotic symptoms, such as hallucinations, disorganized speech, or grossly disorganized behavior. A greater degree of psychosis is required for a diagnosis of schizophrenia or schizophreniform disorder.  (See References)
