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.
- Symptoms: Patients report a combination of:
- Pain symptoms (headaches, back pain, joint pain)
- Gastrointestinal symptoms (nausea, bloating, vomiting)
- 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.
