Ansiety disorders often go untreated:

In a study of patients seen at primary care clinics, nearly 20% had at least one anxiety disorder and 41% of these patients were receiving no treatment.Kurt Kroenke, from the Regenstrief Institute in Indianapolis, Indiana, and colleagues assessed the prevalence and treatment of anxiety disorder by surveying and interviewing 965 patients randomly selected from 15 primary care clinics in the United States.Overall,19.5% of patients had at least one anxiety disorder. The most common disorder was post-traumatic stress disorder, noted in 8.6% of patients, follwed by generalised anxiety disorder in 7.6%,panic disorder in 6.8%, and social anxiety disorder in 6.2%.Diagnosis of an anxiety disorder was associated with worse functional status, more disability days, and more trips to the doctor, the researchers note in the report in the "Annals of Internal Medicine".
