Which are the symptoms of Conversion Disorder?

Conversion Disorder, also known as Functional Neurological Disorder (FND), manifests as neurological symptoms that cannot be explained by a structural disease, often appearing as motor or sensory deficits. These symptoms include sudden paralysis, blindness, or seizures that are physically real and involuntary, resulting from the brain's inability to properly send or receive signals.

What are the most common symptoms of Conversion Disorder?

The symptoms of Conversion Disorder are varied and often mimic other neurological conditions. Because the issue lies in the functioning of the nervous system rather than physical damage, symptoms can be inconsistent. Common presentations include:

• Motor symptoms: Weakness or paralysis of a limb, gait abnormalities, or tremors.


• Sensory symptoms: Sudden loss of vision, hearing, or touch/sensation.


• Seizure-like episodes: Known as non-epileptic attacks, which may look like epilepsy but do not show the same electrical brain activity.


• Speech issues: Difficulty speaking (dysphonia) or complete inability to produce sound.

How does Conversion Disorder affect daily life?

The severity of Conversion Disorder can fluctuate significantly, with some patients experiencing mild, transient symptoms and others facing profound disability. These symptoms often severely impact daily quality of life by limiting mobility, independence, and the ability to work. For the 21 members of our DiseaseMaps.org community, the unpredictability of these episodes is often cited as the most challenging aspect of living with Conversion Disorder.

When should you seek immediate medical attention?

While Conversion Disorder is not structural, any new or sudden neurological deficit requires a prompt medical evaluation to rule out acute conditions like a stroke or brain injury. Seek emergency care if symptoms include sudden confusion, loss of consciousness, or symptoms that are rapidly worsening, as initial diagnosis requires excluding all other potential medical causes.

How do symptoms progress over time?

The course of Conversion Disorder is highly individual. Some individuals may experience a single episode that resolves quickly, while others may have chronic, relapsing symptoms. Early recognition and a multidisciplinary approach are vital, as the prognosis for Conversion Disorder often improves with targeted physical therapy and psychological support aimed at retraining the nervous system.

Next steps

• Consult a neurologist who specializes in functional neurological disorders.


• Seek a referral to a physical therapist experienced in neuro-rehabilitation.
