Generalized anxiety disorder. Causes[edit] Genetics[edit] Generalized anxiety disorder may be hereditary with it running in families.[9] Genetics seem to play a role in this; those with genetic predisposition are more likely to develop GAD, usually in response to a life stressor.[10] Substance induced[edit] Long-term use of benzodiazepines can worsen underlying anxiety,[11][12] with evidence that reduction of benzodiazepines can lead to a lessening of anxiety symptoms.[13] Similarly, long-term alcohol use is associated with anxiety disorders,[14] with evidence that prolonged abstinence can result in a disappearance of anxiety symptoms.[15] However, it can take up to 2 years for anxiety symptoms to return to baseline in about a quarter of people recovering from alcoholism.[16]
