They are characterized by progressive disintegration of different parts of NS and unknown etiology. Up to date there are non-effective treatments for them and only in some cases, palliative drugs are available alleviating partially and temporarily some symptoms in patients.

Multiple Sclerosis may be included in this last group of diseases affected around globally 4 million of patients, but until now it has been classified as autoinmmune disease. However it is difficult to establish its origin and many researchers agree that multiple sclerosis is a neurodegenerative disease where olygodendrocytes dead in relapsing remittent or progressive ways.
