PHAR’s Sheila Reiss Reddy, PhD, MSc, RPh, Eunice Chang, PhD, and Caleb Paydar, in collaboration with Genentech Inc., conducted an analysis of Medicare and Medicaid claims data to examine the epidemiology of Huntington’s disease (HD), which was published in the June issue of Neuroepidemiology. Their study is the first to provide a comprehensive assessment of the prevalence and incidence of HD among Medicare beneficiaries and prevalence of HD among Medicaid beneficiaries, populations about which little was previously known. Their study found higher estimates of prevalence and incidence of HD than previously estimated, and highlighting opportunities for earlier diagnosis.
