Somatoform disorders are a group of psychological disorders in which individuals experience physical symptoms that suggest a medical condition, but no identifiable organic cause can be found. These symptoms are not intentionally produced or feigned.
The four main types of somatoform disorders are:1. Somatization Disorder:
Description: A chronic condition characterized by multiple physical complaints involving different body systems over several years.
Sexual symptoms (irregular menstruation, sexual indifference)
Pseudoneurological symptoms (conversion symptoms like weakness, blurred vision)
Onset: Usually begins before age 30 and persists for many years
Key Feature: Patients frequently visit multiple doctors and undergo numerous medical tests without finding organic cause
2. Conversion Disorder:
Description: Loss or alteration of physical functioning that suggests a neurological disorder but is actually linked to psychological factors
Symptoms:
Paralysis or weakness in limbs
Blindness or double vision
Deafness
Loss of sensation (numbness)
Seizures or convulsions
Difficulty swallowing or lump in throat
Key Feature: Symptoms often appear suddenly after a stressful event and may resolve just as suddenly
La Belle Indifférence: Patients may show surprising lack of concern about their dramatic symptoms
3. Pain Disorder:
Description: Severe and chronic pain that causes significant distress or impairment, with psychological factors playing a major role in onset, severity, or maintenance
Symptoms:
Back pain
Headaches
Pelvic pain
Fibromyalgia-type pain
Key Feature: The pain is real and distressing, but no physical explanation adequately accounts for it
Associated Features: Often accompanied by depression, anxiety, and excessive use of pain medication
4. Hypochondriasis:
Description: Preoccupation with fear of having a serious disease based on misinterpretation of normal bodily sensations
Symptoms:
Excessive worry about health
Interpreting minor symptoms (headache, sweating, cough) as signs of serious illness
Repeated checking of body for signs of illness
Frequent doctor visits or avoidance of medical care due to fear
Key Feature: The fear persists despite medical reassurance and negative test results
Course: Chronic condition that fluctuates with stress levels
Note: In the DSM-5, these disorders have been reclassified under "Somatic Symptom and Related Disorders" with some changes in terminology and criteria.
