Is Conversion Disorder contagious?

Conversion Disorder (also known as Functional Neurological Disorder or FND) is not contagious and cannot be spread through physical contact, social interaction, or environmental exposure. It is a complex neurological condition involving the brain's signaling processes, meaning there is zero risk to family members, caregivers, or friends who spend time with someone diagnosed with the condition.

Is Conversion Disorder contagious in any way?

No, Conversion Disorder is strictly non-communicable. It is a biological and psychological phenomenon occurring within an individual’s central nervous system. Because Conversion Disorder is not caused by bacteria, viruses, or any transmissible pathogen, it is physically impossible to "catch" it from another person. The 21 members of the DiseaseMaps.org community who live with this condition are in no way a risk to those around them.

What causes Conversion Disorder?

While the exact mechanism is still being studied, Conversion Disorder is understood as a problem with the "software" of the nervous system rather than the "hardware." The brain struggles to send or receive signals correctly, leading to symptoms like paralysis, tremors, or seizures without a structural brain lesion. Potential triggers include:

• Significant psychological or physical stress.


• History of trauma (though not present in all cases).


• Chronic pain or physical illness that disrupts neurological pathways.


• Genetic predisposition to heightened sensitivity in the nervous system.

Why is there a misconception about contagion?

The stigma surrounding Conversion Disorder often stems from historical misunderstandings where symptoms were mistakenly labeled as "hysteria" or "mass psychogenic illness." In rare instances of "mass psychogenic illness," groups of people may develop similar physical symptoms due to shared environmental stress or social anxiety; however, this is a distinct social phenomenon and is fundamentally different from a clinical diagnosis of Conversion Disorder.

Next steps

• Consult a neurologist specializing in Functional Neurological Disorder (FND) for a comprehensive care plan.


• Work with a specialized physical therapist to retrain the brain-body connection.


• Join a supportive patient community, such as the one at DiseaseMaps.org, to connect with others who understand the reality of Conversion Disorder.


• Seek therapy with a provider experienced in neuro-psychology to manage stress triggers.
