A Comprehensive Analysis of Stroke Prevalence Among Adults in the United States: Wells Andres, MD

WATCH TIME: 6 minutes

"Stroke prevalence has not changed significantly over the time period, either overall or when we age standardized. We saw the overall prevalence of stroke is about 3% and has remained essentially right around that number over the entire time period. Even when we looked at our demographic subgroups, we didn't see any significant changes, except in men."

Representative data of stroke prevalence estimations inform the clinical community on how to take action with interventions and guide the allocation of resources.¹ Based on previous reports, epidemiological data show a decrease in stroke incidence as well as a decrease in stroke mortality. Currently, there is a lack of recent research for accounting for stroke prevalence in community-dwelling patients across the United States.²

At the 2023 American Academy of Neurology (AAN) Annual Meeting, April 22-27, in Boston, Massachusetts, Wells Andres, MD, a neurology resident at the University of Pennslyvania, presented an analysis of the prevalence of stroke among community-dwelling patients in the United States between 1999 and 2018 using a nationally representative sample. In the analysis, Andres and colleagues calculated age-standardized stroke prevalence over four-year epochs overall, which were stratified by age group, sex, and race/ethnicity.² The researchers concluded that the age-standardized prevalence of stroke has not significantly changed between 1999 and 2018 in the non-institutionalized civilian adult population of the U.S.

Andres sat down with NeurologyLive^® in an interview at the AAN 2023 to provide an overview of the analysis that he presented and what data set was used for the study. In addition, he talked about the subgroups that were examined and if there were any significant changes observed in the data. He also spoke about the limitations of the study design and what could potentially be the lack of change in stroke prevalence over the years.
