Mahdi Barzegar is a graduated of Isfahan university of medical school. I started research in neurological disorders in 2013 and currently conduct research projects in Isfahan neuroscience research center . I am interested in Multiple sclerosis (MS) and Neuromyelitis optica spectrum disorder (NMOSD). I work on epidemiological and clinical aspects of these two diseases and try to speculate physical and mental burden of NMOSD. Also, we try to assess long-term and short-term outcome of NMOSD and MS in Iranian population.
