Demyelination
Demyelination , also called demyelination , is the loss of myelin sheaths . Myelin sheaths surround many nerve fibers ( axons of nerve cells) and serve a higher nerve conduction speed . If several nerve cells are affected, this can be diffuse or focal. The diseases in which this phenomenon occurs are known as demyelinating disease or demyelinating disease, the most common of these diseases is multiple sclerosis .
The destruction of the myelin in the central or peripheral nervous system - in the marrow-forming glia or the myelin sheaths - can occur both in the demyelinating diseases mentioned and after primary damage to the nerve cell bodies or their axons.
Inflammatory , immunopathological , toxic and other processes are possible causes .
