An overview of anxiety disorders

Anxiety disorders are more prevalent than any other mental health problem in the United States. Afflicted persons are often untreated or are treated only by a primary care physician without psychiatric consultation. However, based on current knowledge of the biological and psychological factors involved in these disorders, psychiatry has defined effective treatment that integrates education, psychotherapy, and psychopharmacology. After reviewing current research on possible mechanisms of anxiety, the authors discuss therapeutic interventions and recommend ways to choose appropriate treatment modalities for anxiety-disordered patients.
