Mothers who breastfeed for more than 15 months over their lifetimes may be at lower risk of developing multiple sclerosis (MS), according to American researchers.
The researchers recruited 397 women with newly diagnosed MS or clinically isolated syndrome (CIS) and 433 matched controls, aged, on average, about 37 years. CIS refers to the first episode of neurological symptoms that lasts at least 24 hours. At this stage, neurologists cannot identify the cause. In many cases, however, CIS heralds MS.
