GAD

Definition:

Generalized anxiety disorder (GAD) is characterized by a pattern of frequent, persistent worry and anxiety about several events or activities during at least a 6-month period.

Causes and Risks

Generalized anxiety disorder (GAD) is a common condition. Reasonable estimates for its 1-year prevalence range from 3-8%. The disorder is characterized by excessive anxiety and worry that is out of proportion to the impact of the event or circumstance that is the focus of the worry. 

For example, while college students often worry about tests, a student who persistently worries about failure, despite consistently obtaining good grades, displays the pattern of worry typical of this disorder. 

The person finds it difficult to control the worry. The cause of GAD is not known, but biological and psychological factors play a role. Stressful life situations or maladaptive behavior, acquired through learning, may also contribute to GAD.

The disorder may start at any time in life, including childhood. Most patients with the disorder report that they have been anxious for as long as they can remember. GAD occurs somewhat more often among women than among men.
