Are mental illnesses hereditary?

Mental illnesses have a certain degree of heredity, but the inheritance of mental illnesses requires multi-gene control, and it is difficult for a single gene to play a role. Moreover, the episodes are mostly caused by stimulating factors, that is, they need to rely on certain environmental conditions to have episodes. Stimulus factors are factors that have a greater impact on the patient’s mood, including long-term anxiety, long-term family discord, long-term pressure to go to school, and the pressure of illness. In modern society, there is a lot of pressure, and the number of adverse factors that cause mental abnormality is gradually increasing, so it is necessary to pay attention to loosening the pressure in a timely manner.
