CONVERSION DISORDER/ FUNCTIONAL NEUROLOGICAL SYMPTOM (FNS)

Table of Contents

Definition of Conversion Disorder/ Functional Neurological Symptom (FNS)

Conversion disorder, also known as functional neurological symptom disorder or functional disorder, is a condition characterized by neurological symptoms that cannot be attributed to any identifiable organic or physical cause. These symptoms might affect motor or sensory function and can resemble those of neurological or medical conditions, such as paralysis, weakness, tremors, seizures, or sensory disturbances like blindness or numbness.

However, despite the symptoms mimicking a neurological problem, no neurological explanation or physiological basis can be found through standard medical assessments like imaging tests or laboratory investigations. The symptoms in conversion disorder are believed to be linked to psychological factors or stressors, and they often occur or worsen during stressful periods or times of emotional distress.

People with conversion disorder are not “faking” their symptoms; instead, the condition is believed to be a manifestation of psychological distress or conflict. Treatment often involves a multidisciplinary approach, including psychotherapy, counseling, and sometimes physical therapy or rehabilitation to help manage symptoms and address underlying psychological factors.

It’s important to note that the diagnosis of conversion disorder is made by excluding other possible medical or neurological causes for the symptoms and requires careful evaluation by qualified healthcare professionals, such as psychiatrists, neurologists, or psychologists.

History of Conversion Disorder/ Functional Neurological Symptom

The concept of conversion disorder has a rich history that dates back centuries, evolving through various names and interpretations over time. The term “conversion disorder” originates from the psychoanalytic theories of Sigmund Freud and his contemporaries in the late 19th and early 20th centuries.

  • Freud initially termed this condition “hysteria,” which was believed to be associated with disturbances in the nervous system resulting from unresolved psychological conflicts. He used the term to describe a range of symptoms, including paralysis, tremors, blindness, and other sensory or motor abnormalities, without any identifiable neurological explanation.
  • During Freud’s era, the prevailing belief was that these symptoms were the result of unconscious psychological conflicts or repressed emotions, often related to traumatic experiences. Freud proposed that these unresolved conflicts could be converted into physical symptoms as a way for the mind to express distress, leading to the term “conversion.”
  • Over time, the understanding and classification of this condition evolved within the field of psychiatry and psychology. The Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, has seen changes in terminology and diagnostic criteria. In the DSM-5, published in 2013, the term “conversion disorder” was replaced by “functional neurological symptom disorder” as a way to emphasize the neurological symptoms without implying a specific underlying psychological mechanism.
  • The evolution of understanding conversion disorder/functional neurological symptom disorder has been influenced by advancements in psychology, psychiatry, neuroscience, and medicine. Contemporary views highlight the complex interaction between psychological factors and the nervous system, emphasizing a biopsychosocial approach to diagnosis and treatment.

Today, the condition is recognized as a complex interplay between psychological stressors and neurological symptoms, requiring a comprehensive assessment involving mental health professionals, neurologists, and other healthcare providers to offer effective treatment and support for individuals experiencing these symptoms.

DSM-5 Criteria of Conversion Disorder/ Functional Neurological Symptom

In the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), the diagnosis of Conversion Disorder was replaced with a new diagnostic category known as “Functional Neurological Symptom Disorder.” This change aimed to emphasize the neurological symptoms without implying a specific underlying psychological mechanism. Here are the criteria for diagnosing Functional Neurological Symptom Disorder according to DSM-5:

Criterion A: One or more symptoms of altered voluntary motor or sensory function.

Criterion B: Clinical findings provide evidence of incompatibility between the symptom and recognized neurological or medical conditions.

Criterion C: The symptom or deficit is not better explained by another medical or mental disorder.

Criterion D: The symptom or deficit causes clinically significant distress or impairment in social, occupational, or other important areas of functioning or warrants medical evaluation.

Criterion E: The symptom or deficit is not intentionally produced or feigned (i.e., it is not under voluntary control).

Criterion F: The symptom or deficit is not culturally sanctioned or part of a broadly accepted cultural or religious practice.

For a diagnosis of Functional Neurological Symptom Disorder, the symptoms should be determined as genuine and not the result of malingering or consciously produced. The symptoms cause distress or impairment and cannot be better accounted for by another medical or mental health condition.

It’s important to note that these criteria emphasize the presence of neurological symptoms that are not consistent with known neurological conditions, emphasizing the need for careful evaluation and consideration of various factors before making this diagnosis. A thorough assessment by qualified healthcare professionals, including neurologists and mental health practitioners, is necessary to rule out other medical conditions and properly diagnose Functional Neurological Symptom Disorder.

Etiology of Conversion Disorder/ Functional Neurological Symptom

The exact etiology or cause of Conversion Disorder/Functional Neurological Symptom Disorder is not fully understood and is likely multifactorial, involving a complex interplay of psychological, biological, and social factors. Here are some theories and factors associated with the development of this condition:

Psychological Factors:

Psychological stressors, emotional conflicts, trauma, or unresolved issues are often linked to the onset of conversion disorder. These could include experiences of abuse, significant life stressors, or traumatic events. The symptoms might serve as a way for the individual to cope with or express distress that they are unable to articulate consciously.

Maladaptive Coping Mechanisms:

Some individuals may have difficulties expressing emotions or dealing with stress in adaptive ways. Conversion symptoms might manifest as a subconscious coping mechanism to deal with psychological distress.

Neurobiological Factors:

Research suggests alterations in brain function and connectivity in individuals with conversion disorder. There might be changes in how the brain processes and regulates emotions, sensations, and movements, although the exact neurological mechanisms remain under investigation.

Personality Traits:

Certain personality traits or predispositions might contribute to the development of conversion disorder. For instance, individuals who tend to be more prone to anxiety, have higher levels of suggestibility, or have a history of dissociative experiences might be more susceptible.

Social and Cultural Influences:

Social and cultural factors can play a role in the expression and interpretation of symptoms. Cultural beliefs, societal expectations, or environmental stressors may influence the way symptoms manifest or are perceived by the affected individual or their community.

Psychosocial Learning:

Some theories propose that individuals might learn to associate physical symptoms with relief from distress or attention from others. This learned behavior can reinforce the presence of conversion symptoms.

It’s essential to emphasize that conversion disorder is a complex condition, and its development is likely influenced by a combination of these factors rather than a single cause. The understanding of this disorder continues to evolve through ongoing research in neuroscience, psychology, and psychiatry. Diagnosis and treatment often involve a comprehensive approach that considers biological, psychological, and social aspects to address the underlying factors contributing to the symptoms.

Theories related to Conversion Disorder/ Functional Neurological Symptom

Several theories have been proposed to explain Conversion Disorder/Functional Neurological Symptom Disorder, attempting to elucidate the complex relationship between psychological distress and the manifestation of physical symptoms without identifiable organic causes. Here are some prominent theories related to this condition:

Psychodynamic Theory:

Originating from Sigmund Freud’s work, this theory suggests that conversion symptoms stem from unconscious conflicts or emotions. It proposes that distressing thoughts or emotions are repressed or “converted” into physical symptoms as a way to deal with inner conflicts, trauma, or distressing experiences.

Dissociation and Trauma:

Some theories emphasize dissociation as a mechanism contributing to Conversion Disorder. Dissociation involves a disconnection between thoughts, emotions, identity, and consciousness. Trauma, especially early in life, might lead to dissociative processes, causing physical symptoms as a way to cope with overwhelming emotions or experiences.

Stress and Emotional Distress:

Stress, particularly acute or chronic stressors, is often associated with the onset or exacerbation of conversion symptoms. Emotional distress, including anxiety, depression, or unresolved psychological conflicts, might contribute to the conversion of emotional distress into physical symptoms.

Somatic Symptom Amplification:

This theory suggests that individuals with Conversion Disorder might have a heightened sensitivity to physical sensations, amplifying normal bodily sensations to a significant degree, leading to the perception of severe or abnormal symptoms.

Behavioral Reinforcement:

Some researchers propose that environmental factors, such as attention, support, or reinforcement received when displaying symptoms, can unintentionally reinforce the behavior. This reinforcement might contribute to the persistence or exacerbation of conversion symptoms.

Social-Cultural Factors:

Social and cultural factors play a role in the expression and interpretation of symptoms. Societal expectations, cultural beliefs, or family dynamics might influence the way symptoms are expressed and perceived, shaping the nature of the conversion symptoms.

It’s important to note that these theories are not mutually exclusive, and the development of Conversion Disorder/Functional Neurological Symptom Disorder likely involves a combination of these factors. The understanding of this condition continues to evolve as researchers explore the intricate interactions between psychological, social, and biological elements contributing to the onset and maintenance of these symptoms.

Risk factors for Conversion Disorder/ Functional Neurological Symptom

Several risk factors have been identified that may increase the likelihood of developing Conversion Disorder/Functional Neurological Symptom Disorder. These factors often encompass a combination of psychological, biological, and social elements. Some of the key risk factors include:

Psychological Factors:

Individuals with a history of psychological distress, such as acute or chronic stress, trauma (including physical, emotional, or sexual abuse), or significant life events (bereavement, divorce, etc.), are at higher risk. Unresolved emotional conflicts or difficulties in coping with stress may contribute to the development of symptoms.

Previous Trauma or Adverse Childhood Experiences (ACEs):

Exposure to adverse experiences during childhood, such as neglect, abuse, or traumatic events, has been linked to an increased risk of developing conversion symptoms later in life. Childhood trauma may contribute to the development of coping mechanisms that manifest as conversion symptoms.

Personality Traits:

Certain personality traits or predispositions, such as high levels of anxiety, perfectionism, or a tendency toward emotional avoidance or suppression, might predispose individuals to develop conversion symptoms.

Medical or Psychiatric Comorbidities:

People with other medical conditions or psychiatric disorders, such as anxiety disorders, depression, or other somatic symptom disorders, might have an increased risk of developing conversion symptoms.

Family or Environmental Factors:

Family dynamics, cultural beliefs, or social environments that emphasize the expression of physical symptoms as a way to cope with distress or seek attention may contribute to the development or reinforcement of conversion symptoms.

Neurobiological Factors:

There is ongoing research exploring potential neurobiological mechanisms involved in Conversion Disorder. Changes in brain function, alterations in connectivity, or abnormalities in the way the brain processes emotions and sensations might play a role in predisposing individuals to these symptoms.

Socioeconomic Factors:

Lower socioeconomic status or socioeconomic stressors may also contribute to the risk of developing conversion symptoms, possibly due to increased exposure to adverse life events and limited access to resources for coping and support.

Understanding these risk factors can help clinicians and healthcare professionals identify individuals who might be more vulnerable to developing Conversion Disorder/Functional Neurological Symptom Disorder. Early recognition and intervention aimed at addressing underlying psychological distress and providing appropriate support are essential in managing this condition.
