Multiple Sclerosis Prevalence Nears 1 Million US Patients
By applying a validated algorithm to multiple sets of administrative health data (AHC), researchers have shown that there has been a steady rise in the prevalence of multiple sclerosis (MS) in the US over the past 5 years to nearly 1 million people.
This number is nearly double that of previously reported estimates from prior studies, which had estimated that this population in the US numbered approximately 572,312 (95% CI, 397,004-747,619, and 403,630 individual cases (95% CI 387,445-419,833). Establishing an accurate estimate of MS prevalence in the US is essential for evaluating changes in disease frequency in relation to changing population demographics.
“We must understand the reasons behind the growing MS prevalence estimates in the US,” Mitchell Wallin, MD, MPH, Director for The Multiple Sclerosis Centers of Excellence (MSCoE) East at the US Department of Veterans Affairs (VA), told MD Magazine®. “For example, how are the demographic changes in the US influencing the incidence and mortality experience of MS?”
