Effects of Tysabri Over 12 Months on MS Related Fatigue in Patients With RRMS
A Multi-centre and Prospective Trial to Evaluate the Effects on Multiple Sclerosis Related Fatigue During Treatment With Tysabri in Patients With Relapsing Remitting Multiple Sclerosis Over the Course of 12 Months

Fatigue is a problem in 75-95% of MS patients and many report fatigue as one of their most disabling symptoms which contributes to cognitive and physical difficulties. Treatment that can decrease fatigue will improve the quality of life for this group of patients. Small studies and anecdotal reports have suggested that TYSABRI as opposed to other disease modifying therapies can decrease fatigue in MS patients. Data from a more substantial trial population and a well-defined fatigue scale is warranted to verify these observations.
