WebThe myelinor myelin sheath is a fatty substance that surrounds nerve fibers and its function is to increase the speed of nerve impulses, facilitating communication between neurons. It also allows greater energy savings for the nervous system. Myelin is made up of 80% lipids and 20% proteins. WebThe disease can lead to problems with muscle movement, balance and mental function. Refsum disease causes a fatty acid to build up in cells and harm myelin. Adult Refsum disease (ARD) leads to problems with the brain, eyes, liver, kidneys and bones.
