Suzanne O’Sullivan is a neurologist specializing in epilepsy who practices in London. Many of her patients suffer from so-called conversion disorders: somatic symptoms caused by psychological distress that defy ready diagnosis by medical tests or physical examination. “They are medical disorders like no others,” O’Sullivan writes. “They obey no rules. They can affect any part of the body…. Almost any symptom we can imagine can become real when we are in distress.”
Physicians who practice family medicine, pediatrics, or internal medicine learn that a substantial proportion of people seeking care have inexplicable complaints. Some surveys indicate that at least a quarter of such patients report symptoms that appear to have no physical basis, and that one in ten continues to believe that he has a terminal disease even after the doctor has found him to be healthy.1
Understandably, because the symptoms obscure the psychological genesis, patients seek a physical disorder to explain their condition, and turn to doctors like O’Sullivan to provide a diagnosis.
