Functional neurological symptom disorder

Functional neurological symptom disorder (FNSD), also referred to as dissociative neurological symptom disorder (DNSD), is a condition in which patients experience neurological symptoms such as weakness, movement problems, sensory symptoms, and convulsions. As a functional disorder, there is, by definition, no known disease process affecting the structure of the body, yet the person experiences symptoms relating to their body function.
