LUBBOCK, TX (KCBD) - A new study finds smoking can affect the progression of multiple sclerosis. Smokers are already at higher risk of developing MS and now researchers at Brigham and Women's Hospital say smoking speeds up disease progression.
They studied almost 1500 MS patients and their smoking habits, and then followed them for about three years. Researchers found smokers were more likely to have severe cases of MS at the beginning of the study and tended to decline faster than non-smokers.
There is good news though; those who quit smoking during the study had similar disease progression as people who never smoked.
