Schizophrenia - Cause

Experts don't know what causes schizophrenia. It may have different causes for different people.

  • Genetics: Your chances of getting schizophrenia are greater if your parent, brother, or sister has it. But most people who have a family member with schizophrenia don't get it.
  • Brain chemistry and structure: It's possible that neurotransmitters, which send messages between parts of the brain, don't work the right way in people who have schizophrenia.
  • Problems duringpregnancy: Schizophrenia may be related to problems during the mother's pregnancy that can harm a baby's developing brain and nervous system. These problems include poor nutrition or a viral infection during pregnancy.

Schizophrenia is not caused by anything you did, by personal weakness or bad choices, or by the way your parents raised you.
