It differential diagnosis time! In this scenario you are the diagnostician seeing and communicating with the patient. Please do the following for the case vignette below: Identify the most likely diagnosis by justifying symptoms from the information contained in the example that led you to decide on the diagnosis. Make sure you give as complete a diagnosis as possible. You may not actually have all the information you need to make a diagnosis. Identify what other piece(s) of information you would need (i.e., what else do you need to ask) before you could make a definitive diagnosis. Using your knowledge of statistics and descriptors of the disorder you chose, provide the patient with an idea of course of the disorder. Provide a complete informed consent discussion of treatment for this diagnosis which should include your ‘professional’ decision regarding treatment (make sure you are ‘speaking’ to the patient, not to me!).   A 35-year-old individual named Adam has recently formulated an elaborate plan to cure AIDS with vitamin therapy.

When he appeared at a hospital emergency room loudly demanding names of patients with AIDS, he himself was hospitalized for psychiatric observation.
