SOMATIZATION, the concept
Poorly understood…”crocks”..”turkeys”.. “hysterics”..”worried well”
the tendency to express and communicate psychological distress in the form of somatic symptoms for which they seek medical help
“one of medicine’s blind spots”

Forms of Somatization
Medically unexplained symptoms Hypochondriacal somatization Somatic presentation of psychiatric
disorders (ie., depressive equivalents)

Most common presenting symptoms Abdominal pain chest pain dyspnea headache fatigue
Cough back pain nervousness dizziness

Infectious Diseases
Lyme disease AIDS Infectious mononucleosis Syphilis Chronic Fatigue Syndrome Post-infection syndromes

SOMATIZATION, the cost
10% of total direct healthcare costs with the potential to bankrupt the healthcare financing system
Somatizers have 9x more total charges, 6x more hospital charges, 14x more MD services
Somatizers are sick in bed an average of 7 days a month vs. 0.48 days for the general population
![Page 9: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/9.jpg)
SOMATIC COMPLAINTS
Patients who experience their symptoms but do not deliberately produce them (SOMATOFORM DISORDERS)
Patients who knowingly create symptoms in themselves, either for material gain (MALINGERING), or for more subtle benefits, such as gratification of the patient role (FACTITIOUS DISORDERS)

Relation of Depression and Somatization Patients with SD have a high prevalence of
depression (48-94%) Patients with MDD have substantial levels
of somatization (63-84%) Depression can be treated successfully
when it coexists with SD
Smith, 1992
![Page 33: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/33.jpg)
Relation of Depression and Pain
Patients with chronic pain have a significant current prevalence of depressive disorders
More than half of patients with MDD complain of pain
Pain is reduced with the treatment of depression
Smith, 1992

Factitious Disorders
Psychological symptoms Physical symptoms Munchausen’s syndrome, pseudologica
fantastica, peregrination usually co-morbid with psychiatric conditions intentional production of symptoms but goal
is intangible and psychologically complex
![Page 36: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/36.jpg)
ALERT…ALERT…ALERT...
Numerous surgical scars, usually in the abdominal area
Patient is truculent and evasive Personal and medical history were fraught
with acute and harrowing adventures History of many hospitalizations, malpractice
claims, insurance claims Involved in the healthcare profession
![Page 37: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/37.jpg)
Symptom Types
Total fabrications Exaggerations Simulations of the disease Self-induced disease
![Page 38: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/38.jpg)
A Physical Diagnosis is more likely if…. Symptoms do not meet DSM-IV criteria. Premorbid social history is unremarkable. There is an ABRUPT change in personality,
mood, or ability to function. There are RAPID fluctuations in mental
status. There is lack of response to usual biologic or
psychologic interventions.
![Page 39: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/39.jpg)
Principles of Management
Emphasize explanation Arrange for regular follow-up Treat mood/anxiety disorder Minimize polypharmacy and multiple
diagnostic tests Provide specific treatment when indicated
![Page 40: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/40.jpg)
![Page 41: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/41.jpg)
Remember….
Reassurance that “nothing is wrong” does NOT help.
The patient does not want symptom relief but rather a RELATIONSHIP and understanding.
Little is to be gained by saying that “it’s all in your head”.
![Page 42: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/42.jpg)
Remember...
You should acknowledge the patient’s plight, avoid challenging the patient.
A positive organic diagnosis will not cure the patient.
SOMATIZATION MAY CO-EXIST WITH ANY PHYSICAL ILLNESS AND MAY INITIALLY MASK THE ILLNESS.
![Page 43: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/43.jpg)
Malingering
Intentional fabrication of symptoms to achieve a secondary gain, usually material benefits
![Page 44: SOMATOFORM DISORDERS Maria L.A. Tiamson, MD Asst. Professor, Psychiatry New York Medical College](https://reader036.vdocuments.us/reader036/viewer/2022062320/56649cd75503460f9499e805/html5/thumbnails/44.jpg)
