# Do weak electromagnetic fields help multiple sclerosis symptoms that get worse before the period?

Yes, in two women. Their premenstrual worsening of multiple sclerosis symptoms resolved within two months of starting the treatment. This is based on only two women, so we cannot know how often it would work.

 Early or limited evidence

Two women with progressive multiple sclerosis experiencing premenstrual symptom worsening

## What they did

This is a case report of two women with progressive multiple sclerosis who experienced regular worsening of symptoms starting about a week before menstruation and improving when menstruation began. They were treated with weak electromagnetic fields applied outside the brain.

## What they found

Their premenstrual worsening of MS symptoms resolved two months after starting treatment with weak electromagnetic fields.

## What it means for you

Weak electromagnetic fields might help reduce the premenstrual worsening some women with MS experience. Based on only two women, we cannot say how often this works or how it compares to other treatments. The findings suggest hormones during the menstrual cycle may affect MS, though the exact mechanisms are unclear.
