There are a number of reasons that have been identified or suspected to cause anxiety disorders. One of these is the theory that anxiety disorders are caused by chemical imbalances. Another theory is that the genetic disposition of a person determines the likelihood that a person would develop an anxiety disorder when given the right trigger. On the other hand, there are also theories that say that anxiety disorders are learned behaviors and that unresolved issues from a person’s past cause anxiety disorders. In addition to these, there is also a theory that says that not being able to properly manage symptoms of anxiety can cause the condition to become an anxiety disorder.
