The concept that hearing and cognitive functions are linked emerged decades ago.1 With the growth of this interdisciplinary field of cognitive hearing science, the complex relationships between hearing and cognition have become better elucidated. More specifically, in older adults with hearing loss (HL), 3 areas of research have advanced our understanding of hearing and cognition. First, it is clear that HL is associated with cognitive decline, and the degree of HL appears to be associated with the risk of cognitive dysfunction in a dose-dependent manner.2 Second, recent studies3 suggest positive associations of hearing rehabilitation with cognitive abilities. Third, there is growing evidence that communication and speech recognition outcomes with hearing aids and cochlear implants (CIs) are influenced by the cognitive abilities of the user.4
