A review of the epidemiology and approaches to the treatment of social anxiety disorder.

This review presents current literature on the epidemiology and treatment of social anxiety disorder (social phobia). This illness has been demonstrated to be the most common anxiety disorder with a 1-year prevalence of 7 to 8% and a lifetime prevalence of 13 to 14% in patients aged between 15 and 54 years. Social anxiety disorder can be classified into 2 subtypes, discrete and generalised. Morbidity is high with this disorder, and 70 to 80% of patients have co-morbid mental disorders. Although effective treatments are available, social anxiety disorder is under-recognised and under-treated. Treatments that have been systemically studied and have shown efficacy in patients with social anxiety disorder include pharmacotherapy (selective serotonin reuptake inhibitors, monoamine oxidase inhibitors, reversible inhibitors of monoamine-A and benzodiazepines) and short term psychotherapies (cognitive behaviour therapy, social skills training and exposure in vivo therapy). Beta-blockers are useful in treating performance-related anxiety. Few published data are available on the treatment of social anxiety disorder with a combination of pharmacotherapy and psychotherapy. We conclude this review by discussing proposed algorithms for treating both subtypes of social anxiety disorder.
