Overview
Conversion disorder, now more commonly called functional neurological disorder (FND), is a condition where psychological stress or trauma manifests as physical neurological symptoms. These symptoms are genuine and can be severely disabling, but they cannot be explained by structural damage or disease in the nervous system. The term "conversion" historically referred to the idea that psychological distress is "converted" into physical symptoms, though modern understanding recognizes this as an oversimplification of a complex mind-body interaction.
This condition affects how the nervous system functions rather than its structure, similar to a software problem rather than hardware damage in a computer. People with conversion disorder experience real symptoms such as paralysis, blindness, seizures, or movement problems that significantly impact their daily lives. These symptoms are not consciously produced or "faked" - brain imaging studies show altered patterns of brain activity during symptoms, confirming their neurological basis.
Conversion disorder is more common than many realize, accounting for up to one-third of neurology outpatient visits. It can affect people of any age, gender, or background, though it's most commonly diagnosed in young adults and is slightly more prevalent in women. With proper treatment combining physical rehabilitation, psychological therapy, and education, many people with conversion disorder experience significant improvement or complete recovery of function.

Causes
Conversion disorder results from complex interactions between psychological, biological, and social factors. Understanding these can help in treatment planning.
Psychological Factors
- Acute stress: Recent traumatic events or life changes
- Chronic stress: Ongoing difficult life circumstances
- Trauma history: Childhood abuse or neglect

Diagnosis
Diagnosing conversion disorder requires careful evaluation to rule out other neurological conditions while identifying positive signs of FND.
Diagnostic Criteria
- One or more symptoms affecting voluntary motor or sensory function
- Clinical findings incompatible with recognized neurological disease
- Symptoms not better explained by another medical condition
- Significant distress or impairment in functioning
- Positive clinical signs of functional symptoms
Clinical Evaluation
- Detailed history: Symptom onset, triggers, pattern
- Neurological examination: Looking for positive signs
- Psychiatric assessment: Identifying stressors and comorbidities
- Functional assessment: Impact on daily activities
Positive Signs of FND
| Sign | Description | Significance |
|---|---|---|
| Hoover's sign | Hip extension returns with contralateral flexion | Functional leg weakness |
| Tremor entrainment | Tremor changes with distraction tasks | Functional tremor |
| Give-way weakness | Sudden loss of resistance during testing | Functional weakness |
| La belle indifférence | Lack of concern about symptoms | Suggestive but not diagnostic |
Diagnostic Tests
- MRI/CT scan: Rule out structural abnormalities
- EEG: Differentiate from epileptic seizures
- Video-EEG monitoring: For seizure-like episodes
- Neuropsychological testing: Assess cognitive function
- Laboratory tests: Rule out metabolic causes
Important Diagnostic Principles
- Diagnosis should be made on positive findings, not just exclusion
- Normal test results don't mean symptoms aren't real
- Multiple specialists may be involved in diagnosis
- Early diagnosis improves treatment outcomes
- Transparent communication about diagnosis is essential
Treatment
Treatment for conversion disorder requires a multidisciplinary approach addressing both physical symptoms and underlying factors.
Treatment Principles

Frequently Asked Questions
Are conversion disorder symptoms "real" or "all in my head"?
Conversion disorder symptoms are absolutely real and not imagined or faked. While the symptoms originate from altered brain function rather than structural damage, they cause genuine disability and distress. Brain imaging studies show real changes in brain activity during symptoms. The phrase "all in your head" is misleading because it implies the symptoms are imaginary or under voluntary control, which they are not. Your symptoms deserve the same medical attention and validation as any other health condition.
Why do I have normal test results if my symptoms are so severe?
Conversion disorder affects how the nervous system functions, not its structure. Think of it like a software problem in a computer rather than broken hardware. Standard medical tests like MRI or CT scans look for structural damage, tumors, or inflammation, which aren't present in FND. The nervous system's "programming" is disrupted, causing real symptoms despite normal-appearing anatomy. This is why specialized clinical examinations looking for positive signs of FND are more useful than standard tests in making the diagnosis.
Can conversion disorder symptoms come and go?
Yes, conversion disorder symptoms often fluctuate in severity and may come and go. Symptoms may worsen during times of stress, fatigue, or emotional distress, and improve during relaxation or distraction. Some people experience complete temporary remissions followed by symptom return. This variability is actually characteristic of FND and doesn't mean the condition is any less real or valid. Understanding your symptom patterns and triggers can be helpful in managing the condition.
Will I need psychological treatment even though my symptoms are physical?
Psychological treatment is often helpful because conversion disorder involves the complex interaction between mind and body. This doesn't mean your symptoms are "just psychological" - rather, therapy can help address factors that may be contributing to or maintaining symptoms. Therapy can teach coping strategies, stress management, and help process any underlying emotional issues. Many people benefit from a combination of physical rehabilitation and psychological support, as both aspects are important for recovery.
Can children develop conversion disorder?
Yes, children and adolescents can develop conversion disorder, and it's actually quite common in pediatric neurology clinics. In young people, symptoms often develop in response to academic pressure, social stress, bullying, family conflicts, or other stressors they may struggle to express verbally. Children may be less able to articulate emotional distress, making physical symptoms a form of communication. Treatment in children often involves the whole family and focuses on creating a supportive environment for recovery. The prognosis in children is often very good with appropriate treatment.
Is conversion disorder the same as malingering or faking symptoms?
No, conversion disorder is completely different from malingering or faking symptoms. In conversion disorder, symptoms are involuntary and not under conscious control. People cannot simply "stop" their symptoms at will. Malingering involves deliberately producing false symptoms for external gain (like avoiding work or obtaining compensation), while conversion disorder symptoms are genuine and often cause significant distress to the person experiencing them. The distinction is crucial: people with conversion disorder need compassionate medical care, not suspicion or dismissal.
