RESUMO
The most prevalent non-traumatic debilitating illness affecting young individuals is multiple sclerosis (MS) (2). Both industrialized and emerging nations are seeing an increase in the incidence and prevalence of MS, whose underlying etiology is still unknown. In addition to some well-known environmental variables, such as vitamin D or ultraviolet B light (UVB) exposure, Epstein-Barr virus (EBV) infection, obesity, and smoking, MS is a complicated illness with several genes that can influence disease vulnerability (3). The Medline, Pubmed, Embase, NCBI, and Cochrane databases were searched for studies of patients with non-alcoholic fatty liver disease. Incidence, etiology, and management options were analyzed. The etiopathogenesis of MS is convoluted. The processes through which genetic and environmental risk factors for the illness alter risk are still largely unclear, despite significant improvements in their detection. Discovering these processes might result in the identification of novel and more focused therapy targets as well as disease pathways.
