American Academy of Neurology: Multiple Sclerosis risk factors and susceptibility

 

artificial-intelligence-3382507__340During the annual American Academy of Neurology meeting, researchers shared their thoughts and presented recent discoveries on risk factors and susceptibility in multiple sclerosis (MS)—a hot topic in the field. Who develops this chronic illness and why are questions that are still puzzling the research community. In general, it’s agreed that a combination of genes and environmental factors likely play a role in the development of MS.
