As discussed in Chapters 1 and 2, the early onset form of schizophrenia (EOS) is rare with a prevalence rate of approximately one in 10,000; however, schizophrenia occurs in approximately 1% of the adult population, and in about one third of cases, individuals begin experiencing psychotic symptoms in adolescence (Findling & Schulz, 2005; Kodish & McClellan, 2008). Schizophrenia is often preceded by subclinical symptoms and adjustment problems with a gradual deterioration in functioning over a period of months or years (Walker, Kestler, Hochman, & Bollini, 2005). More specifically, adults with a diagnosis of schizophrenia demonstrate increased social withdrawal, anxiety, academic difficulties, and thought problems that frequently begin in adolescence (Findling & Schulz, 2005). This suggests that school psychologists and other school-based mental health professionals are on the front line to identify and intervene for students who currently have or who are at risk of developing schizophrenia in the early stages of functional decline.
