The symptoms are real and cause significant distress, but they are not consciously produced, and the underlying problem is not brain damage but rather a disruption in the way the brain functions. FNSD is linked to psychological factors, trauma, and stress, leading to a functional problem with the nervous system rather than a structural one.                                    Symptoms vary but often involve sensory or motor functions:

Movement Problems:

Weakness, paralysis, tremor, abnormal movements, or difficulty with walking.

Sensory Changes:

Numbness, tingling, vision problems, hearing loss, or difficulty swallowing.

Speech and Swallowing:

Slurred speech, difficulty finding words, a new stutter, or feeling like something is stuck in the throat.

Seizure-like Episodes:

Attacks or seizures that aren’t caused by epilepsy.
