Statistics and Risks
According to the American Psychiatric Association, GAD has a lifetime prevalence of approximately 5% of the population in the United States. About half of those with GAD report their symptoms beginning in childhood or adolescence. Symptoms are usually chronic and wax and wane over time, often corresponding with stress.
Studies of twins suggest that GAD may have a genetic component. It has long been thought that anxiety traits in general tend to run in families.
