ABSTRACT
Chapter 2 involves the case of “Mr. S,” a young male at clinical high-risk for psychosis, who was molested when he was younger and developed paranoid feelings toward his sister. He spent a year receiving treatment in the clinic during which he developed strong feelings about some of the people in the clinic, culminating in a most alarming episode in which he began working at the laundromat close to his therapist’s apartment. Mr. S is one of our patients who actually transitioned to a psychotic disorder. Therefore, issues surrounding determining who becomes psychotic and how a person’s condition manifests as one actually transitions from being prodromal or clinical high-risk to fully psychotic will be discussed. This chapter also describes the many other diagnoses that people often receive before their first psychotic break, such as depression, anxiety, post-traumatic stress disorder, attention deficit hyperactivity disorder, and others.
