Schizophrenia typically first appears in individuals during their late teens to early 30s, with men usually experiencing symptoms at a slightly younger age than women. However, it is possible for schizophrenia to develop at any age, including childhood or later in life. It is less common for schizophrenia to develop after the age of 45, but it is still possible. Early diagnosis and treatment of schizophrenia are important for better management of the condition and improved outcomes.
