Management of Conversion Disorder (Functional Neurologic Symptom Disorder)

Overview

Step 1: Establish the Diagnosis Correctly

• Positive clinical signs (e.g., Hoover test, inconsistent disability on serial exams, la belle indifference) support the diagnosis.
• Rule out anti-NMDA receptor encephalitis, TIAs, atypical migraines, periodic paralysis.
• Do NOT confront the patient with implications of malingering - this is counterproductive and damages the therapeutic alliance.

Step 2: Communication and Therapeutic Alliance

• Name the disorder - using the term "functional neurological disorder" (not "it's all in your head") has been shown to improve the therapeutic alliance.
• Explain symptoms in terms of a nervous system dysfunction (software problem, not structural damage) - patients respond better to this framing.
• Demonstrate empathy, validate the patient's suffering, and communicate that symptoms are real.
• Offer reassurance that critical tests are normal and that improvement is expected, but avoid implying the patient is fabricating symptoms.
• Frame long-term management as maximizing function rather than eliminating symptoms entirely.

Step 3: Psychological Therapies (First-Line)

Cognitive Behavioral Therapy (CBT)

• CBT is the best-evidenced psychological treatment for FND, particularly for psychogenic non-epileptic seizures (PNES).
• Consistent benefit demonstrated across multiple systematic reviews, especially within multidisciplinary frameworks.
• Targets maladaptive illness beliefs, dysfunctional coping, and symptom-perpetuating behaviors.

Psychodynamic and Insight-Oriented Therapy

• Useful especially where unconscious conflict, trauma, or interpersonal dynamics are identified as precipitants.
• Particularly for patients with chronic conversion.

Behavioral Techniques

• Focus on improving self-esteem, assertiveness, and the ability to express emotions.
• Improve communication skills and interpersonal functioning.

Hypnosis / Suggestion-Based Approaches

• Hypnosis and parenteral sodium amobarbital (amytal) interview or lorazepam can resolve acute conversion symptoms - symptom resolution under these conditions supports the diagnosis.
• Useful adjunctively, though evidence is limited and results can be transient.

Biofeedback and Relaxation Training

• Helpful as adjunct therapies, especially for autonomic or sensory symptoms.

Step 4: Physiotherapy

• Physiotherapy is a foundational treatment for motor conversion symptoms (weakness, gait disorder, tremor).
• A program of slowly progressive exercises helps restore functioning, corrects maladaptive movement patterns, and rebuilds confidence.
• In chronic cases, muscle contractures can develop - physiotherapy is then medically essential.
• Even without contractures, balance problems and muscular symptoms respond well to targeted physical therapy.
• Physiotherapy is most effective when integrated within a multidisciplinary framework and when the therapist is familiar with FND.

Step 5: Pharmacological Treatment

• There is no purely pharmacologic approach proven sufficient for somatic/functional symptoms themselves.
• Polypharmacy should be avoided; unnecessary medications can reinforce illness behavior.

Step 6: Multidisciplinary Rehabilitation

• Multimodal, tailored approaches produce the best outcomes.
• CBT + physiotherapy remain foundational.
• Multidisciplinary inpatient rehabilitation is indicated for severe or treatment-refractory cases.
• Neuromodulation (rTMS, tDCS) shows promising but inconsistent results.

Step 7: Acute/Emergency Management

• Build rapport and demonstrate empathy before any therapeutic intervention.
• Do not order excessive tests beyond clinical justification - this reinforces illness behavior.
• Psychiatric consultation is appropriate if organic causes are excluded.
• Patients can generally be discharged with outpatient primary care or psychiatric follow-up if no acute safety concern exists.
• Explain that acute life-threatening diagnoses have been excluded and that psychiatric/psychological support is helpful.

Prognosis and Special Considerations

• Acute presentations often have a benign, self-limited course with appropriate support and reassurance.
• Early intervention prevents chronicity. Once chronic, intensive multimodal treatment is required.
• Psychological interpretations work poorly early in the course; focus first on reassurance and function.
• Childhood trauma (sexual or physical abuse) may be a predisposing factor - handle sensitively.
• Avoid labeling, confronting, or invalidating patients - these worsen outcomes significantly.
