A nurse is providing education 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?

Choice A reason: Schizophrenia rarely presents in early childhood; cases in preschoolers are extremely uncommon and considered childhood-onset schizophrenia. Choice B reason: While symptoms may persist into later life, new-onset schizophrenia is unusual in older adults and should prompt investigation for other causes such as dementia or medical illness. Choice C reason: Schizophrenia most commonly develops in late adolescence to early adulthood, with men typically diagnosed in their late teens to early 20s and women in their late 20s to early 30s.
