To be diagnosed with conversion disorder you must have at least one symptom, but you may also have many. The appearance of symptoms is linked to the stressful event and typically occur suddenly.
Diagnosis of conversion disorder may be difficult. The physical symptoms are most often caused by a physical disorder. It is important for your doctor to carefully consider any physical causes for your symptoms. Your doctor will ask about your symptoms and medical history. A complete physical exam will be done. You may be asked to undergo some of the following tests to rule out an underlying disease:
Laboratory testing to rule out irregular blood glucose levels (hypoglycemia or hyperglycemia),
, or drug-related causes
Imaging studies, such as chest
—a test that uses sensors to evaluate electrical activity in the brain
Electrocardiogram (ECG, EKG)
—a test that records heart activity by measuring electrical currents through the heart muscle
Spinal fluid examination to check for neurological causes
If no physical cause is detected, the patient may either be referred to a neurologist or for a psychiatric consultation.
Psychological disorders can carry a feeling of being stigmatized. It is important that you do not let this prevent you from seeking treatment.
In some cases, you may begin to recover spontaneously. After physical causes for the symptoms have been ruled out, you may begin to feel better and symptoms may begin to fade. In some cases, you may need assistance in recovering from their symptoms. Treatment options may include the following: Counseling and psychotherapy—Discussing the stressful event with a counselor may help you cope with the underlying cause of the physical symptoms.Pharmacological therapy—In some cases, antidepressants may be used to speed recovery.Identifying and removing environmental triggers to decrease anything stimulating the conversion disorder.
Therapy may be needed to overcome disuse/paralysis of a limb and to relearn normal behaviors.
There are no guidelines to preventing conversion disorder because it occurs after a specific, traumatic event. However, about 25% of patients with conversion disorders have future episodes. Continued counseling will help you learn how to deal with stressors throughout life and perhaps prevent future episodes.
