“…Previous research which assessed cognitive performance as an outcome associated with HA use is inconsistent (Mulrow, Aguilar et al, 1990; Tesch-Römer, 1997; Lehrl et al, 2005; Van Hooren et al, 2005; Acar et al, 2011; Choi et al, 2011; Lin et al, 2011), and no study that we are aware of has examined the long-term protective effects of HA use against cognitive decline. In the present study, there were no differences in cognitive performance or the incidence of cognitive impairment between hearing aid users and non-users.…”

Objective To clarify the impact of hearing aids on mental health, social engagement, cognitive function, and physical health outcomes in older adults with hearing impairment. Design We assessed hearing handicap (Hearing Handicap Inventory for the Elderly; HHIE-S), cognition (Mini Mental State Exam, Trail Making, Auditory Verbal Learning, Digit-Symbol Substitution, Verbal Fluency, incidence of cognitive impairment), physical health (SF-12 physical component, basic and instrumental activities of daily living, mortality), social engagement (hours per week spent in solitary activities) and mental health (SF-12 mental component) at baseline, 5 years prior to baseline, and 5 and 11 years after baseline. Study sample Community-dwelling older adults with hearing impairment (N=666) from the Epidemiology of Hearing Loss Study cohort. Results There were no significant differences between hearing aid users and non-users in cognitive, social engagement or mental health outcomes at any time point. Aided HHIE-S was significantly better than unaided HHIE-S. At 11 years hearing aid users had significantly better SF-12 physical health scores (46.2 versus 41.2; p=0.03). There was no difference in incidence of cognitive impairment or mortality. Conclusion There was no evidence that hearing aids promote cognitive function, mental health, or social engagement. Hearing aids may reduce hearing handicap and promote better physical health.

“…The cognitive tests were performed before hearing aid fitting, and we assumed that cognitive performance remained unchanged over time. A few studies have shown small but significant improvements in performance on visually based cognitive tests after using hearing aids for 6 months ( Choi, Shim, Lee, Yoon, & Joo, 2011 ; Lehrl, Funk, & Seifert, 2005 ), while other studies have shown no change ( Pinheiro, Iório, Miranda, Dias, & Pereira, 2012 ; Tesch-Römer, 1997 ; van Hooren Anteunis et al., 2005 ). In a literature search reported by Kalluri and Humes (2012) , it was concluded that there was no strong evidence for longer term effects (up to 2 years) of hearing aid amplification on cognition.…”

Dynamic Relation Between Working Memory Capacity and Speech Recognition in Noise During the First 6 Months of Hearing Aid Use

The present study aimed to investigate the changing relationship between aided speech recognition and cognitive function during the first 6 months of hearing aid use. Twenty-seven first-time hearing aid users with symmetrical mild to moderate sensorineural hearing loss were recruited. Aided speech recognition thresholds in noise were obtained in the hearing aid fitting session as well as at 3 and 6 months postfitting. Cognitive abilities were assessed using a reading span test, which is a measure of working memory capacity, and a cognitive test battery. Results showed a significant correlation between reading span and speech reception threshold during the hearing aid fitting session. This relation was significantly weakened over the first 6 months of hearing aid use. Multiple regression analysis showed that reading span was the main predictor of speech recognition thresholds in noise when hearing aids were first fitted, but that the pure-tone average hearing threshold was the main predictor 6 months later. One way of explaining the results is that working memory capacity plays a more important role in speech recognition in noise initially rather than after 6 months of use. We propose that new hearing aid users engage working memory capacity to recognize unfamiliar processed speech signals because the phonological form of these signals cannot be automatically matched to phonological representations in long-term memory. As familiarization proceeds, the mismatch effect is alleviated, and the engagement of working memory capacity is reduced.

“…As such, cognitive tests may serve as sensitive outcome measures of hearing rehabilitation. For example, Lehrl and colleagues (Lehrl, Funk, & Seifert, 2005) found that in a hearing-impaired group of 70-year-olds, use of a hearing aid for 2 to 3 months improved working memory capacity compared with controls matched on IQ, chronological age, and hearing impairment. However, more global measures of cognitive skills, not necessarily measuring working memory capacity, showed no significant improvement after 12 months of hearing aid use (van Hooren et al, 2005), although it is possible that performance may have declined if hearing aids had not been worn.…”

Normal Adult Aging and the Contextual Influences Affecting Speech and Meaningful Sound Perception

It is widely accepted that hearing loss increases markedly with age, beginning in the fourth decade ISO 7029 (2000). Age-related hearing loss is typified by high-frequency threshold elevation and associated reductions in speech perception because speech sounds, especially consonants, become inaudible. Nevertheless, older adults often report additional and progressive difficulties in the perception and comprehension of speech, often highlighted in adverse listening conditions that exceed those reported by younger adults with a similar degree of high-frequency hearing loss (Dubno, Dirks, & Morgan) leading to communication difficulties and social isolation (Weinstein & Ventry). Some of the age-related decline in speech perception can be accounted for by peripheral sensory problems but cognitive aging can also be a contributing factor. In this article, we review findings from the psycholinguistic literature predominantly over the last four years and present a pilot study illustrating how normal agerelated changes in cognition and the linguistic context can influence speech-processing difficulties in older adults. For significant progress in understanding and improving the auditory performance of aging listeners to be made, we discuss how future research will have to be much more specific not only about which interactions between auditory and cognitive abilities are critical but also how they are modulated in the brain.
