When there is enough myelin sheath protection, the central and peripheral nerves of the brain function optimally. Any damage to the layer exposes the brain nerves and causes neurological dysfunction Vit-B12 deficiency causes lack of myelin sheath leads to disperssion of nerve signals and develops polyneuropathy.
