No one can be sure what causes any form of anxiety disorder, and generalized anxiety disorder (GAD) is no different. Having said that, exciting research is being carried out all the time, and every day GAD is better understood – this better understanding may, in the future, help to prevent this condition from ever occurring in the first place in many people.
Here are what the leading experts believe to be the major causes of GAD:
A growing number of doctors believer that chemical imbalances are the single biggest cause of generalized anxiety disorder. A large percentage of people who suffer from GAD have inconsistent levels of certain neurotransmitters in the brain. These neurotransmitters – serotonin and norepinephrine – are responsible for carrying messages to and from the various nerve endings.
If they’re present in the wrong amounts they can cause someone to be much more likely to experience severe anxiety when compared to someone with correct levels of these neurotransmitters.
Heredity is another potential cause of GAD that’s undergoing considerable research. Many respected experts in the field believe that all forms of anxiety disorders may actually run in families.
There are already a number of respected studies that suggest a person is far more likely to develop GAD at some point in their lives if one of their direct relatives also has an anxiety disorder.
The theory that lifestyle factors can cause GAD to develop is the least investigated, but it’s also the theory that’s gaining momentum quicker than any other.
This theory suggests that generalized anxiety disorder is a learned condition, rather than one that develops randomly, or through some other cause. Lifestyle factors such as parenting, childhood experiences, traumas, and bereavements all have the potential to contribute to the developing of GAD, according to this theory.
