Women Face Much Higher MS Risk. A New Discovery May Help Explain Why.

A small study found more than 100 cerebrospinal fluid protein differences in women with multiple sclerosis.

Researchers compared CSF from three women with MS and three without it, identifying 72 elevated and 46 reduced proteins.

Many of the changes were linked to immune activity, neuron repair, and hormone-related pathways.

The early results may help explain why MS is more common in women and suggest new biomarkers or treatment targets.
