Survey study, 2000

Do multiple sclerosis symptoms change at different times in the menstrual cycle?

It varies. In some women with MS, neurologic symptoms worsened during the 2 weeks before their period. In others, there was no change across the cycle. Some women also had PMS symptoms.

Early or limited evidence 5 women with relapsing-remitting multiple sclerosis, not on hormone therapy or birth control pills

What they did

5 women with relapsing-remitting MS who were not on hormone therapy or birth control pills tracked their symptoms daily, recorded their body temperature, and completed a PMS questionnaire for 3 consecutive menstrual cycles.

What they found

Researchers identified four different patterns when reviewing the temperature charts and questionnaires: one group had worsening MS symptoms during the 2 weeks before their period, another group had no cycle-related changes, one group had PMS symptoms, and one woman had chronic severe depression.

What it means for you

MS symptoms may change with the menstrual cycle in some women but not others. This is a very small study (5 women) and identifies a tool that could help MS patients track how their condition relates to their cycle. Much larger studies are needed to understand this pattern.
