Research conducted and funded by the National Institute of Mental Health (NIMH) has found that many mental disorders are caused by a combination of biological, environmental, psychological, and genetic factors. In fact, a growing body of research has found that certain genes and gene variations are associated with mental health disorders.
Your family history is one of your best clues about your risk of developing mental disorders and many other common illnesses. Certain mental illnesses tend to run in families, and having a close relative with a mental disorder could mean you are at a higher risk.
If a family member has a mental disorder, it does not necessarily mean you will develop one. Many other factors also play a role. But knowing your family mental health history can help you determine whether you are at a higher risk for certain disorders, help your doctor recommend actions for reducing your risk, and enable both you and your doctor to look for early warning signs
I hope this helped you understand whether mental health is genetic.
