In current literature there seems to be increasing emphasis on the psychogenic aspects of diseases, even those illnesses which are usually considered purely biological in etiology, such as pulmonary tuberculosis.17 In an effort to clarify the area of "psychosomatic disorders" and to differentiate conversion hysteria, organ neuroses, and typical biological diseases, the psychiatric term "psychophysiologic autonomic and visceral disorder" is now preferred. This term implies that the "symptoms are due to a chronic and exaggerated state of normal physiologic expression of emotion... which may lead to structural changes."2 Psychophysiologic disorders, then, are restricted to those disorders that involve organs and viscera innervated by the autonomic nervous system, rather than by a more voluntary control or perception.
