Summary

This study looks at how multiple sclerosis (MS) symptoms, like fatigue and thinking skills, change during different phases of the menstrual cycle. About 300 females with MS who still have periods will track their symptoms using a phone app for six months. The goal is to find patterns that could help manage symptoms better.
