Dawson's Fingers appearing on an MRI scan Multiple sclerosis and other demyelinating diseases of the<unk>  nervous system (CNS) produce lesions (demyelinated areas in the CNS) and glial scars or scleroses. They present different shapes and histological findings according to the underlying condition that produces them. Demyelinating diseases are traditionally classified in two kinds: demyelinating myelinoclastic diseases and demyelinating leukodystrophic diseases. In the first group a normal and healthy myelin is destroyed by a toxic, chemical or autoimmune substance. In the second group, myelin is abnormal and degenerates. The second group was denominated dysmyelinating diseases by Poser Therefore, since Poser demyelinating diseases normally refers to the myelinoclastic part. Demyelinating diseases of the CNS can be classified according to their pathogenesis into five non-exclusing categories:<unk> due to inflammatory processes, viral<unk> <unk> caused by acquired metabolic derangements, hypoxic–ischaemic forms of<unk> and<unk> caused by focal compression.
