Schizophrenia
• Any medical condition, medicine, or substance of abuse that can affect brain homeostasis and cause psychosis: distinguished from schizophrenia by its relatively brief course and the alteration in mental status that could suggest an underlying delirium
• Other psychiatric disorders: source of greatest confusion
• Mood disorders with psychosis: indistinguishable from schizophrenia cross-sectionally but have a longitudinal course that includes full recovery
