A62 year old female presents to the er with right arm and leg numbness and weakness, otherwise she is at her baseline, on exam your doctor identifies those fnd’s and nothing else. how does the cause of fnd’s differ from the cause of ams?

AMS is secondary to issues that effect the whole brain while FND's are secondary to damage to a very small/local areas of the brain.

Explanation:

FND  stands for Functional Neurological Disorder. It is a condition where an individual experiences any neurological symptoms like blackouts, movement disorders, sensory symptoms, weakness or numbness. The brain starts functioning improperly in a person suffering from functional neurological disorder.

AMS affects the whole brain while FND affects a small part of the brain.

Thus the answer is ---

AMS is secondary to issues that effect the whole brain while FND's are secondary to damage to a very small/local areas of the brain.
