Although in speaking, sclerosis is commonly referred to as memory impairment , often observed in old age, this disease does not have an age or disability. Symptoms of multiple sclerosis usually occur in young people and in middle age, that is, from 15 to 40 years. "Scattered" in this case means "plural," and the term "sclerosis" means a scar, since the disease causes a replacement of normal nerve tissue by a connective one.
Multiple Sclerosis - Causes and Symptoms of Disease
The exact causes of the onset of the disease have not been established to date. Presumably, multiple sclerosis is an autoimmune reaction of the body to the influence of certain external factors (viral infections, toxins), which can be largely aided by hereditary predisposition.
Clinical signs in the early stages of multiple sclerosis are often not obvious. This is explained by the fact that neighboring cells take on the function of affected areas, and obvious neurological symptoms appear even after a sufficiently extensive lesion.
