Multiple sclerosis is a neurological disease that affects the brain, brain stem and spinal cord. Myelin, the substance that covers nerve fibers, is damaged by our own defense cells and then the ability of the nerves to conduct the orders of the brain is interrupted. This causes the patient has neurologic symptoms that affect different systems.
In this way the patient may experience loss of vision in one eye by unaneuritis optics, impaired balance, double vision, tingling or parts of the body asleep or loss of strength. The patient may improve spontaneously and after a while introducing a new outbreak.
Depending on the timing and extent of recovery we divide it into:
Relapsing-remitting (RRMS) is characterized by recurring outbreaks from time to time and are repeated as they occur varying degrees of residual symptoms. It is the most common way to start, although many patients subsequently evolve to a secondary progressive form.
Primary progressive (PPMS): in these patients symptoms progress from the onset of the disease, with occasional period of stability and less disability. Present progressive functional impairment from the beginning, not presenting exacerbations. This form usually have a later age of presentation and greater disability. Represents 10% of cases the onset of the disease
Secondary progressive (SPMS): The disease begins in outbreaks, as a relapsing-remitting, then take a progressive course. It is responsible for the greatest degree of disability.
Progressive-relapsing (PRMS): these patients have a progressive course with occasional exacerbations.
Currently there are many treatments and try to control aand patient to prevent this deficit.
Enferemedad Devic
NMO, also known as Devic syndrome, is a demyelinating disease that affects in its typical form exclusively to the optic nerve and spinal cord, and is a combination of bilateral optic neuropathy and myelopathy. There is no other demyelinating territories, at least in the typical form of this entity.
