Management of common anxiety disorders

Anxiety disorders affect 16 percent of the U.S. population. Family physicians treat 90 percent of patients presenting with one or more anxiety disorders. Common anxiety disorders include generalized anxiety disorder, panic disorder and social phobia. Differentiation among these disorders may be difficult, since symptoms and presentations are often similar. Underlying medical disorders and depressive illness may mimic or coexist with anxiety disorders. The chronic, remitting and relapsing nature of anxiety disorders requires the institution of a long-term plan of care. The integration of pharmacologic and psychotherapeutic interventions generally produces the greatest benefit to patients. Pharmacotherapeutic options frequently prescribed by family physicians include benzodiazepines, beta blockers, monoamine oxidase inhibitors, tricyclic antidepressants and azapirones. Useful psychotherapeutic models featuring brief interventions include supportive and cognitive approaches, and behavioral therapies, such as biofeedback, in vivo exposure and systematic desensitization.
