Conversion Disorder, also known as Functional Neurological Symptom Disorder (FNSD), is a mental health condition in which a person experiences neurological symptoms that cannot be explained by a medical condition. The symptoms are thought to be an expression of psychological distress or trauma. Follow us here at Art of Mixing Gold & Silver Jewelry

Diagnostic Criteria

To diagnose Conversion Disorder (FNSD), the following criteria must be met:

1. Presence of neurological symptoms: The person experiences one or more symptoms that affect movement, sensation, or other bodily functions, such as:

• Weakness or paralysis
• Tremors or tics
• Seizures or convulsions
• Numbness or tingling
• Vision or hearing problems

2. Inconsistent or unusual symptoms: The symptoms do not conform to a recognizable neurological or medical condition, and may be inconsistent or unusual in their presentation.

3. No underlying medical condition: A thorough medical evaluation does not reveal any underlying medical condition that could explain the symptoms.

4. Psychological distress or trauma: The symptoms are thought to be an expression of psychological distress or trauma, such as:

• Stress
• Anxiety
• Depression
• Post-traumatic stress disorder (PTSD)

5. Significant distress or impairment: The symptoms cause significant distress or impairment in social, occupational, or other areas of life.

Additional criteria

• The symptoms are not intentionally produced (i.e., not factitious disorder).
• The individual may exhibit "la belle indifférence," a lack of concern about their symptoms.
