Schizophrenia runs in families. According to the National Institute of Mental Health, it occurs in 1% of the general population, but occurs in 10% of people who have a first-degree relative with this disorder, such as a parent, brother, or sister. Scientists believe several genes are associated with an increased risk of schizophrenia, but that no gene causes the disease by itself.
But, it probably takes more than genes to cause schizophrenia. Scientists think interactions between genes and the environment are necessary for schizophrenia to develop.
