Schizophrenia is a complex illness that may partly involve your genes. But other events in your life may also play a role.

Symptoms in teens can come on gradually over 9 months or more. They can sometimes imitate those of other problems such as anxiety or depression. Especially at first, symptoms may look like the stuff of typical teen years: bad grades, changing friends, trouble sleeping, or irritability.
