Pregnancy in women with two types of MS may mitigate MS progression



Women with either relapsing (R-MS) or primary progressive disease (PPMS) who do not bear children are more likely to have higher disability scores than women who had a least one child, results of their research show.

The research was presented at the meeting of the American Academy of Neurology held in April in Honolulu.

OR it could be that the excess insulin in the mother's system is taken up and used by the growing baby.
