Psychogenic diseases are physical illnesses that stem from emotional or mental stresses.
In most cases, a structural or anatomical abnormality has not been identified, as seen in an organic disease, however this does not account for possible genetic, biochemical, electrophysiological or other abnormalities that may be present but for which we do not have the technology or background to identify.
Psychogenic disease is a broader category than psychosomatic disease, in that it can include the hysterical form, where there is no physiologic change in peripheral tissues, as well as the psychosomatic form, where there is some physiologic alteration.
Psychogenic fever is one of the most common psychosomatic diseases and usually occurs during a psychopathologic process. Patients with psychogenic fever have acute or persistent body temperature above normal range in psychologically stressful situations. In spite of numerous case reports on psychogenic fever, there are few epidemiological studies.
