The
anxiety disorders group is one of most prevalent set of psychiatric diagnoses.
Specific phobia and social phobia are known as the most prevalent from the
group (6-12% and up to 10%, respectively).
Post-traumatic stress disorder comes
in third position with a lifetime prevalence varying from 1% in Western Europe,to 10% in countries that have been exposed to long-term violence. The other
anxiety disorders have a lower prevalence such as 2-5% for panic disorder 3-5%
in generalized anxiety disorder and less than 3% for obsessive-compulsive disorder.
The combination of psychotherapy and pharmacotherapy are generally regarded as
first line treatment. However, about 25% of patients respond poorly to
treatment and show a high risk of chronicity. The high prevalence and high risk
for chronicity have contributed to an annual total societal cost of active
anxiety disorders in the US over the decade of the 1990s estimated over $42
billion. Read more>>>>>>
