Effect of the 2020 CMS telehealth expansion on diagnostic prevalence of Alzheimer's disease and related dementias

Preliminary evidence supports a possible positive relative effect of the CMS telehealth expansion on ADRD diagnostic prevalence among the FFS 65+ population in counties with broadband. While improvements in ADRD detection may have occurred in counties with broadband following the expansion, the substantial decrease in ADRD prevalence overall is likely a consequence of the COVID-19 pandemic and should be explored further.
