MULTIPLE SCLEROSIS: ETIOLOGY, PATHOGENESIS AND CLINICS (PART I)
Multiple sclerosis (MS) - is one of the most socially significant problems of modern neurology. The most important reason of increasing the amount of people with MS is because of absolute growth of diseases and rising the quality of diagnostic and widening the probability of therapy. MS came in first place among the diseases that lead to disability of youth. The perception of MS has been changed to a disease that «damages myelin sheath of the brain and spinal cord conductors», where the periods of exacerbation followed by periods of almost complete clinical well-being. It is also known that in the early stages of this disease there is damage to the axons themselves, therefore MS is not only considered as an autoimmune demyelinating disease, but also as neurodegenerative. The trigger of the disease are viruses, psycho-emotional stress and poor environmental conditions. This disease has a geographical aspect, the farther from the equator people live, the greater the probability tocontract this disease. The disease is characterized by a variety of clinical manifestations. The variety of neurological symptoms is due to a multiplicity of foci of demyelination and their localization in brain and spinal cord. Therefore, there may be a wrong diagnosis of the debut of MS, which in turn leads to improper change in current therapy of MS.
