The exact cause of anxiety disorders is unknown; but anxiety disorders -- like other forms of mental illness -- are not the result of personal weakness, a character flaw, or poor upbringing. As scientists continue their research on mental illness, it is becoming clear that many of these disorders are caused by a combination of factors, including changes in the brain and environmental stress.
Like certain illnesses, such as diabetes, anxiety disorders may be caused by chemical imbalances in the body. Studies have shown that severe or long-lasting stress can change the balance of chemicals in the brain that control mood. Other studies have shown that people with certain anxiety disorders have changes in certain brain structures that control memory or mood. In addition, studies have shown that anxiety disorders run in families, which means that they can be inherited from one or both parents, like hair or eye color. Moreover, certain environmental factors -- such as a trauma or significant event -- may trigger an anxiety disorder in people who have an inherited susceptibility to developing the disorder.
