Causes of anxiety disorders

There is no single factor that causes anxiety disorders but a number
of risk factors that may to contribute to their development.
Environmental factors: Issues such as poverty, early separation from
the family, family conflict, critical parents, and the lack of a
strong support system can all lead to chronic anxiety.
Personality traits: Individuals with low self-esteem and poor coping
skills are more likely to develop an anxiety disorder.
Brain chemistry: A chemical imbalance of brain signaling molecules or
stress hormones (cortisol) may contribute to anxiety disorder
development.
Genetics: Genetic factors may play a role in anxiety disorder
development. One risk factor may be a biological vulnerability to
stress.
Trauma: Anxiety disorders may develop following a traumatic event or
early life abuse.
