Dementia, called the “greatest global challenge for health and social care in the 21st century,”1(p2673) occurs in 47 million persons globally. This number is projected to triple by 2050. With no cure and no treatments to alter its natural history, public health prevention efforts are paramount. Hearing loss (HL) is a novel yet treatable risk factor for dementia.1 In the article by Golub and colleagues2 in this issue of JAMA Otolaryngology–Head & Neck Surgery, the importance of understanding the association between hearing and cognitive performance for older adults is highlighted. Novel to this study is the focus on adults with hearing in the normal range.
