When does schizophrenia start?

Donna Hill Howes, RN
Family Medicine
Schizophrenia is a disease that has several types of symptoms, some of which start earlier than others. The more well-known symptoms, such as hallucinations and delusions, typically start when a man is around 16 to 19 years old or in his early 20s. A woman with schizophrenia more typically experiences hallucinations or delusions when she is in her mid-20s or early 30s. It is not yet known why men develop symptoms earlier than women. Symptoms of schizophrenia may actually start earlier than age 16. The problem is that behaviors such as irritability and sleep problems may be symptoms of the disease or may be normal teenage behaviors. As more research is done, experts should know more about when the symptoms of this lifelong disease begin.

Schizophrenia symptoms most commonly manifest themselves between the ages of 16 and 30. It is rare for individuals who cannot drive (under age 16) and those 45 or older to show signs of the disease. And it’s important to note that symptoms in men tend to appear earlier than in women.

Symptoms of schizophrenia usually start between ages 16 and 30. Men often develop symptoms at a younger age than women. People usually do not get schizophrenia after age 45.

In most cases, schizophrenia first appears in men during their late teens or early 20s. In women, schizophrenia often first appears during their 20s or early 30s.
