Multiple sclerosis 插畫檔

Multiple sclerosis. Multiple sclerosis is characterized by the successive appearance of circumscribed demyelination foci (plaques), disseminated within the white matter of the central nervous system (brainstem and periventricular regions, preferentially). This demyelination is responsible for a slowing down or blockage of nerve conduction, inducing in particular sensory and motor disorders. Although it is known that it is demyelination that causes the symptoms of multiple sclerosis, we do not know what causes this demyelination. An autoimmune origin of the disease is suspected
