As discussed two weeks ago, multiple sclerosis can be a difficult disease to diagnose. But even before and after the diagnosis, there are many other questions as well, from the genetic and geographic risk factors that contribute to the disease to the various treatment options that have reached the market over the last 30 years. ScienceLife sat down with Jacqueline Bernard, assistant professor of neurology and one of the physicians in our multiple sclerosis clinic, to discuss the ins and outs of this complex disease. In the three videos, Dr. Bernard covers the warning signs of MS, how doctors and patients decide on the right treatment for each individual case, and ongoing research into why African-American and Hispanic women are at elevated risk for the disease.
