Classification & external resources
Somatoform disorders are characterised by multiple somatic complaints or physical symptoms such as pain, nausea, depression, dizziness. Somatoform disorders are physical symptoms which present as part of a general medical condition. However, no general medical condition, other mental disorder, or substance is adequately diagnosed. The complaints are serious enough to cause significant emotional distress and impairment of social and/or occupational functioning. An inadequate diagnosis might be the result of inconclusive or faulty test results or in some cases intentional malpractice in which a caregiver deliberately mishandles a patient's health care to derive some benefit. (See munchausen syndrome by proxy.)
A diagnosis of a somatoform disorder implies that psychological factors are a large contributor to the symptoms' onset, severity and duration. It is important to note that somatoform disorders are not the result of conscious malingering or factitious disorders.
Recognized somatoform disorders
The somatoform disorders recognized by the Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association are:
Proposed somatoform disorders
Additional proposed somatoform disorders are:
- Abridged somatization disorder - at least 4 unexplained somatic complaints in men and 6 in women
- Multisomatoform disorder - at least 3 unexplained somatic complaints from the PRIME-MD scale for at least 2 years of active symptoms
These disorders have been proposed because the recognized somatoform disorders are either too restrictive or too broad. In a study of 119 primary care patients, the following prevalences were found:
- Somatization disorder - 1%
- Abridged somatization disorder - 6%
- Multisomatoform disorder - 24%
- Undifferentiated somatoform disorder - 79%
