By Sally Robertson, BSc. The term demyelination refers to loss of the myelin sheath that surrounds and protects axons in the central nervous system. Demyelination occurs as the result of diseases that damage the myelin sheath or the cells that form it.

Multiple sclerosis is an inflammatory, demyelinating disease of the CNS. In pathologic specimens, the demyelinating lesions of MS, called plaques (see the image below), appear as indurated areasâhence the term sclerosis. Demyelination in multiple sclerosis. Luxol fast blue (LFB)/periodic acid-Schiff (PAS) stain confers an intense blue to myelin. Loss of myelin is demonstrated in this chronic plaque. Note that absence of inflammation may be demonstrated at the edge of chronic lesions.
