Conversion disorders - how do they affect life?

20 września 2025
Relatively rare conversion disorders, also known as functional neurological disorders, are a complex group of mental health conditions that manifest through physical symptoms. This means that while medical tests do not confirm any organic damage to the nervous system, the patient experiences real difficulties in daily life. Most commonly, these include speech or movement problems, but also tremors or loss of sensation.

For individuals affected by conversion disorders, it is an extremely distressing experience that - without a specialist diagnosis - is often mistaken for neurological diseases. According to psychologist Mateusz Nesterok, conversion disorders remain a rarely discussed topic in public discourse. This is due to the complex nature of the phenomenon, as patients genuinely suffer, yet imaging and lab tests often show no abnormalities. The lack of a clear cause for conversion disorders leads to feelings of misunderstanding and stigma.

What are conversion disorders?

According to ICD-10, the common feature of dissociative and conversion disorders is a partial or complete loss of integration between:
  • memories of the past,
  • sense of identity,
  • sensory perceptions,
  • and control over body movements.
These symptoms may take the form of paralysis, gait disturbances, mutism, stuttering or blindness, and sometimes even seizure-like episodes. Very often, the symptoms of conversion disorders closely resemble somatic illnesses. Importantly, they are not being faked - they typically occur involuntarily and are completely real for the patient.

Most cases of conversion disorders tend to resolve within a few weeks or months - especially when triggered by traumatic life experiences, particularly sudden ones. On the other hand, chronic conversion disorders - especially persistent sensory disturbances or paralysis - may point to deeper, unresolved emotional conflicts.

What causes conversion disorders?

It is now believed that conversion disorders are of psychogenic origin - meaning they are related to the psyche. They most often appear in response to traumatic events, but also during emotional crises or situations where the patient could not find another way to cope with their emotions.

Very often, the symptoms of conversion disorders reflect the patient's own beliefs about what a physical illness might look like. For example, if someone is convinced that severe stress can cause paralysis, they may actually experience sudden limb weakness. This is a specific type of defense mechanism, where the body converts psychological tension into physical symptoms.

Nesterok emphasizes that conversion disorders should not be seen as faking or exaggeration. For the patient, it is a real experience that demonstrates just how powerfully the mind can affect the body. It is a clear example of why the biopsychosocial perspective is entirely valid.

How are conversion disorders diagnosed?

Patients with conversion disorders usually first consult neurologists, as their symptoms resemble neurological conditions. Only after ruling out organic causes and conducting thorough psychiatric diagnostics can an accurate diagnosis be made. For this reason, diagnosing conversion disorders can often take considerable time.

A key element in diagnosing a conversion disorder is determining whether the symptoms are directly linked in time to a stressful life event or possibly to chronic stress. It is also important to observe whether the symptoms improve or change depending on the patient's emotional state.

How are conversion disorders treated?

The foundation of treatment for conversion disorders is typically psychotherapy - especially cognitive behavioral therapy, which helps the patient recognize the connection between stress and physical symptoms. In cases of trauma-related disorders, EMDR therapy can also be effective.

Additionally, relaxation techniques, occupational therapy, and physiotherapy are used to help restore proper motor and sensory functions. When depression or anxiety is present, medication may also be prescribed by a doctor.

According to Mateusz Nesterok, trust between the patient and therapist is essential. Only within a safe therapeutic relationship can the patient gradually face difficult emotions and begin to regain control over their body and life.

What is the prognosis for conversion disorders?

The prognosis for conversion disorders varies. In many cases, symptoms resolve on their own or after starting psychotherapy - especially when related to short-term episodes triggered by sudden stress. In other cases, they may persist longer or return during times of crisis.

It’s important to remember that psychoeducation plays a major role in the healing process. Understanding that these symptoms are not imagined or faked, but rather a natural defense mechanism of the body, helps reduce guilt and improves cooperation with the therapist. Healthy habits also make a difference - such as good sleep hygiene, physical activity, stress management, and social connections.

FAQ: Conversion disorders

What are conversion disorders?

Conversion disorders are mental health conditions where emotional distress and stress manifest as physical symptoms - such as difficulty walking, speaking, or feeling sensations. Medical tests typically reveal no organic damage.

What is conversion in psychology?

In psychology, conversion is a defense mechanism in which psychological tension is transformed into physical symptoms. The person is not faking and cannot control the symptoms - they experience them as completely real.

What are examples of conversion behaviors?

Common symptoms include partial paralysis, walking difficulties, stuttering, voice loss, tremors, seizure-like episodes, or numbness in different parts of the body.

How does someone with conversion disorder behave?

A person with conversion disorder may display symptoms that resemble neurological diseases, often triggered by intense stress or traumatic events. These symptoms can intensify during emotional moments, disappear on their own, and later return. They are real and distressing to the individual, significantly affecting daily life.

How do conversion disorders differ from somatic illnesses?

The key difference is that conversion disorders usually show no detectable organic changes in medical tests - their symptoms stem from psychological causes. Somatic diseases involve physical damage or disease processes that can be confirmed through diagnostics. Conversion symptoms are strongly linked to emotional stress and can vary greatly, while somatic illnesses generally follow a more predictable clinical course.
