A nurse is assisting with an in-service to a group of staff members about schizophrenia. Which of the following age groups should the nurse include as the age when schizophrenia is typically diagnosed?

A. Preschooler: Schizophrenia is not typically diagnosed in preschoolers. Early childhood development issues may occur, but the onset of schizophrenia usually occurs later in life. B. School-age: While some symptoms may begin to appear during the school-age years, schizophrenia is not commonly diagnosed at this age. Diagnosis is more likely to occur in later developmental stages. C. Young adulthood: Schizophrenia is most commonly diagnosed in young adulthood, typically between the late teens and early 30s. This age range is when the onset of psychotic symptoms usually occurs, making it crucial for staff to understand the timing of diagnosis for effective intervention. D. Older adulthood: While late-onset schizophrenia can occur, it is much less common. Most cases are diagnosed in young adulthood, and the prevalence decreases significantly in older adulthood. Understanding the typical age of diagnosis helps healthcare professionals identify and support individuals at risk.
