not to identify particular objective facts that differentiate one medical condition from another; instead, the main goal is to validate the real suffering experienced by people living with an invisible illness and to provide social support for them as they cope with it. Political actions While there is general agreement on the optimal treatment for Lyme disease, the existence of chronic Lyme is generally rejected because there is no evidence of its existence. Even among those who believe in it, there is no consensus over its prevalence, symptoms, diagnostic criteria, or treatment. The evidence-based perspective is exemplified by a 2007 review in The New England Journal of Medicine, which noted the diagnosis of chronic Lyme disease is used by a few physicians despite a lack of "reproducible or convincing scientific evidence", leading the authors to describe this diagnosis as "the latest in a series of syndromes that have been postulated in an attempt to attribute medically unexplained symptoms to particular infections." Medical authorities agree with this viewpoint: the Infectious Diseases Society of America (IDSA), the American Academy of Neurology, the Centers for Disease Control and Prevention (CDC), and the National Institutes of Health (NIH), advise against long-term antibiotic treatment for people who identify as having chronic Lyme disease, given the lack of supporting evidence and the potential for harmful side-effects including toxicities. A minority, primarily not medical practitioners, holds that chronic Lyme disease is responsible for a range of unexplained symptoms, sometimes in people without any evidence of past infection. This viewpoint is promoted by many who have been told they have the condition by people who lack experience in science or medicine. Groups, advocates, and the small number of physicians who support the concept of chronic Lyme disease have organized to lobby for recognition of this diagnosis, as well as to argue for insurance coverage of long-term antibiotic therapy, which most insurers deny, as it is at odds with the guidelines of major medical organizations. Paul G. Auwaerter, director of infectious disease at Johns Hopkins School of Medicine, cited the political controversy and high emotions as contributing to a "poisonous atmosphere" around Lyme disease, which he believes has led to doctors trying to avoid having Lyme patients in their practices. IDSA lawsuit In 2006, Richard Blumenthal, the Connecticut Attorney General, opened an antitrust investigation against the IDSA, accusing the IDSA Lyme disease panel of undisclosed conflicts of interest and
