Generalized Anxiety Disorder
We all have worries, uncertainties, and fears, but generalized anxiety disorder (GAD) is excessive or unrealistic unease or concern about life's problems. Although the disorder often manifests without any specific cause, large issues of modern life (such as terrorism, the economy, and crime) can bring it about, as can individual circumstances like dealing with an illness. GAD affects about 6.8 million people in the United States, and symptoms include restlessness, fatigue, irritability, impatience, difficulty concentrating, headaches, upset stomach, and shortness of breath. Anxiety disorders like GAD are treated with antianxiety drugs, antidepressants, psychotherapy, or a combination of these.
