Neuroleptics can also cause demyelination. 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.euroleptics can also cause demyelination.

When the immune system releases antibodies that attack myelin, the spinal cord or/and optic nerve become inflamed which in turn causes numbness, weakness or paralysis of the limbs (transverse myelitis) or/and blindness in one or both eyes (usually temporary) or loss of colour vision (optic neuritis).ome people with Devicâs disease have only one attack and recover completely without any lasting consequences but most patients experience relapses. These are usually milder than in patients with the so-called monophasic Devicâs disease, however, each attack causes further damage to myelin.
