What is the Difference Between Conversion Disorder and Hypochondriasis?
🆚 Go to Comparative Table 🆚Conversion disorder (also called functional neurological symptom disorder) and hypochondriasis (now referred to as illness anxiety disorder) are both somatoform disorders, psychiatric conditions that cause unexplained physical symptoms. However, they differ in their manifestations and characteristics:
Conversion Disorder:
- Involves a single symptom related to voluntary motor or sensory functioning.
- Symptoms typically do not conform to known anatomic pathways or physiologic mechanisms.
- Symptoms are not better explained by another medical or mental condition.
- Patients may experience a sudden and severe loss of physical functioning that has no medical explanation.
- People with conversion disorder often also experience depression or anxiety disorders.
Illness Anxiety Disorder (Hypochondriasis):
- Previously referred to as hypochondriasis.
- The person is preoccupied with the fear of having a serious illness.
- Patients misinterpret physical symptoms and fixate on the fear of having a life-threatening condition.
- They may frequently check themselves for signs of illness and take extreme precautions to avoid it.
- Unlike somatic symptom disorder, a person with illness anxiety disorder generally does not experience symptoms.
In summary, conversion disorder is characterized by a sudden and severe loss of physical functioning without a medical explanation, while illness anxiety disorder is characterized by a preoccupation with the fear of having a serious illness and misinterpretation of physical symptoms.
