Every person experiences anxiety at times throughout life. It may be considered a normal part of development. The experience gained by dealing with life's episodes of anxiety can help a person deal with subsequent anxiety-provoking situations in the future; however, for some, anxiety may become persistent, unrelenting, and disabling.

Generalized anxiety disorder (GAD) has been estimated to occur with an incidence of about 5% of the general population. Women are affected more than men [1]. Comorbidity with major depression, other anxiety disorders, and other psychiatric disorders may be as high as 90% [1].
