Psychosomatic disorders, also known as psychophysiological disorders, are a category of somatic disorders whose onset, development, regression, and prognosis are closely related to psychosocial stressors. There are narrow and broad definitions of psychosomatic disorders. Psychosomatic diseases in the narrow sense refer to somatic organic diseases in which psychosocial factors play an important role in the pathogenesis and development, such as coronary heart disease, primary hypertension and ulcer disease. Psychosomatic diseases in the broad sense are somatic organic diseases and somatic functional disorders in which psychosocial factors play an important role in the pathogenesis and development. And such somatic functional disorders in which psychosocial factors play an important role in the pathogenesis and development are called psychosomatic disorders, such as migraine. Therefore, the broad concept of psychosomatic disorders includes psychosomatic diseases and psychosomatic disorders in a narrow sense. There is also an intersection and overlap between psychosomatic disorders and psychosomatic disorders themselves. Some scholars refer to psychosomatic disorders in general terms to include part of psychosomatic disorders and part of neurological disorders. Thus, the broad categories of psychosomatic disorders and psychosomatic diseases are sometimes almost synonymous.
