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.

The myelin sheath is essential for the proper functioning of the nervous system. When the myelin is damaged, nerve impulses slow down, and the nerve cell begins to wither. Diseases such as multiple sclerosis can result from damaged myelin sheaths. The sheath increases the electrical resistance of the cell by a factor of 5,000, which prevents the electrical current from leaving the axon of the nerve cell. The process of forming the myelin sheath is known as mylenization.
