FND or functional neurological disorder is a complex condition where the body shows physical neurological symptoms without a clearly identifiable problem in the nervous system. The exact causes of this condition have not been clearly identified, however, stress is often seen as a major contributor. Treatment for FND should ideally begin at an early stage, but the diagnosis usually takes time as there is no underlying condition to identify or diagnose. It is thus important to consult a neurologist or psychiatrist as soon as the symptoms start appearing.

This condition causes problems in the physical capabilities of the patient such as their ability to walk, their senses, seeing and hearing and swallowing. The symptoms often vary in severity and might fluctuate. The symptoms that show are not in control of the patient. While the exact causes of FND are not known, some of the contributing factors are reaction to extreme stress, psychological or physical trauma and other neurological disorders. FND is more closely related to the functioning of the brain rather than some specific brain damage like a stroke.
Symptoms of FNDThe symptoms of FND vary depending on the type of the disorder and are problematic enough to impair a person’s ability to lead a regular life. Symptoms usually affect movement, senses, and functioning of the body. Some of the various symptoms are-
- Difficulty in hearing or deafness
- Trouble concentrating
- Abnormal, involuntary movements such as tremors
- Problems in swallowing
- Seizures and loss of consciousness
- Speech and vision problems
- Paralysis or weakness
- Loss of balance
Causes of FNDThere are no known causes of this condition. The parts of the brain that control the muscles and senses are involved in this disorder without an underlying disease. Symptoms often appear suddenly after extreme stress or they happen due to physical or emotional trauma. Other factors include change or disruption in brain structure or changes in the cellular and metabolic level. Triggers for FND cannot always be successfully identified.
Risk factors associated with FNDSome of the various factors that increase the risk of functional neurological disorder are-
- Suffering from a previous neurological disorder such as epilepsy, migraines, and movement disorder.
- Occurrence of emotional or physical trauma or extreme stress
- Having a mental health condition such as mood and behavioral disorders and dissociative disorders.
- Having a family history of neurologic disorders
- Having a history of physical or sexual abuse during childhood
