In recent years close attention has been given to the relationship between physical disorders and mental symptoms with a search for, on the one hand, a physical basis for mental disorders and on the other for a psychological basis for various physical conditions. Psychosomatic medicine deals with several group of patients. Those of special interest to the physician are described as follows: 1) Cardiac neurosis, comprising patients who suffer from various physical symptoms but do not have any bodily disease 2) "Vascular hypertension" where a physical disease exists but the original causative factors were of an emotional nature and 3) symptoms resulting from reactive anxiety in a physical illness, where the patient does have an organic disease but some of his symptoms do not arise from this disease and are caused by mental factors. The treatment to be employed in various disorders is discussed. It is stressed that psychiatry should be integrated with all other branches of medicine and artificial distinctions between body and mind should be obliterated.
