Multiple sclerosis, long considered a disease of white females, has affected more black women in recent years, a new study finds. Hispanic and Asian women, who have previously seemed to be at less risk of MS, remain so, researchers report May 7 in Neurology. The findings bolster a theory that vitamin D deficiency, which is common in people with dark skin in northern latitudes, contributes to MS.
MS is a debilitating condition in which the protective coatings on nerves in the central nervous system get damaged, resulting in a loss of motor control, muscle weakness, vision complications and other problems.
The US National Multiple Sclerosis Society estimates that 2.1 million people worldwide have the condition.
