We also studied the main categories of MS articles and found that the research on MS is concentrated around five main categories: symptoms, diagnosis, the ways to reduce the symptoms of the disease such as therapy or rehabilitation, and prevalence of the MS. The results of this study can help the researchers and policy makers realize the panorama of multiple sclerosis research and design future research.
