A biological substrate for somatoform disorders: importance of pathophysiology.
Somatoform disorders are troubling to both patients and physicians. The diagnosis regrettably relies on the presence of subjective distress in the absence of objective findings. As a result, there is always the possibility that a diagnosis will be "missed." There is a clear underlying physiology of distress, which implies that there is a two-way street--both psychosomatic and somatopsychic in terms of production and experience of somatoform symptoms. Studies on communication pathways from the immune system to the brain provide exciting new information on the pathophysiology of inflammation-associated symptoms.
