What Causes Schizophrenia?

Medical experts are still working to understand the exact causes of schizophrenia. However, research suggests that the following may play a role:

  • Genes: You’re six times more likely to develop schizophrenia if a close relative has the condition. Researchers believe that genes likely play a role in determining who gets this disease, but have ruled out the possibility that it occurs due to a single genetic variation.
  • Brain chemistry: Low levels of the brain chemicals dopamine and glutamate have been linked with schizophrenia. This may cause symptoms by reducing or changing communication between brain cells.
  • Health before and after birth: There is some evidence to suggest that pregnant people who develop viruses or suffer from nutritional deficiencies during the second and third trimesters may be more likely to have a child that develops schizophrenia later in life. Autoimmune disorders may also increase the risk of developing the disease.
  • Substance abuse: Some studies indicate that using mind-altering drugs, including marijuana, during adolescence may put people more at risk for developing schizophrenia in adulthood.
