Anxiety disorders are common. According to the National Institute of Mental Health, 19% of Americans over the age of 18 had an anxiety disorder in the past year, and 31% of Americans will experience an anxiety disorder during their lifetimes.
One of the most common anxiety disorders is generalized anxiety disorder. To identify if someone has generalized anxiety disorder, a clinician will look for symptoms such as excessive, hard-to-control worry occurring most days over six months. The worry may jump from topic to topic. Generalized anxiety disorder is also accompanied by the physical symptoms of anxiety.
