“…The hearing aids are mostly used for treating hearing loss among people with cognitive impairment [87]: they seem to be more used by people in better health and of higher socioeconomic status [51] and there is mounting evidence of their efficacy to improve cognitive function in this population [97]. In a randomized trial conducted during a 4-month period, people using hearing aids showed a small but significant improvement in their cognitive performance as assessed by the Short Portable Mental Status [98].…”

In recent years, there has been increasing research interest in the correlation between hearing impairment and cognitive decline, two conditions that have demonstrated a strong association. Hearing loss appears as a risk factor for cognitive impairment, especially among certain populations, notably nursing home residents. Furthermore, hearing loss has been identified as a modifiable age-related condition linked to dementia, and it has been estimated that midlife hearing loss, if eliminated, might decrease the risk of dementia in the general population. Several mechanisms have been suggested to explain the pathologic connections between hearing loss and dementia; however, clear evidence is missing, and the common pathophysiological basis is still unclear. In this review, we discussed current knowledge about the relationship between hearing loss and dementia, and future perspectives in terms of the effects of hearing rehabilitation for early prevention of cognitive decline.

“…Besides the effect of hearing loss on social interaction, behavioral and electrophysiological data underline the hypothesis that the cognitive load caused by the effort to communicate results in a decline of cognitive resources available for other cognitive tasks such as memory [Pichora-Fuller et al, 2016]. Therefore, research has increasingly focused on the restoration of hearing loss and the question whether auditory rehabilitation via hearing aids or cochlear implants (CIs) might counteract age-dependent cognitive decline and help to prevent dementia [Dawes et al, 2015;Jayakody et al, 2018a, b;Maharani et al, 2018;Moberly et al, 2019].…”

“…Assessments using verbal material may lead to an underestimation of cognitive abilities [Dupuis et al, 2015;Wong et al, 2019]. This has necessitated the development of cognitive test batteries that are specially adapted to the hearing impaired (HI) subjects, such as the hearing-impaired Montreal Cognitive Assessment or the Cambridge Neuropsychological Test Automated Battery (CANTAB) and the Repeatable Battery for the Assessment of Neuropsychological Status for hearing-impaired individuals (RBANS-H) or the ALAcog [Claes et al 2016[Claes et al , 2018Völter et al, 2017;Lin et al, 2017;Moberly et al, 2019]. The aim of this prospective longitudinal study was to analyze the impact of cochlear implantation in a large homogenous population of CI users by applying a comprehensive non-auditory cognitive test battery.…”

Introduction: Age-related hearing loss affects about one-third of the population worldwide. Studies suggest that hearing loss may be linked to cognitive decline and auditory rehabilitation may improve cognitive functions. So far, the data are limited, and the underlying mechanisms are not fully understood. The study aimed to analyze the impact of cochlear implantation on cognition in a large homogeneous population of hearing-impaired adults using a comprehensive non-auditory cognitive assessment with regard to normal-hearing (NH) subjects. Material and Methods: Seventy-one cochlear implant (CI) candidates with a postlingual, bilateral severe or profound hearing loss aged 66.3 years (standard deviation [SD] 9.2) and 105 NH subjects aged 65.96 years (SD 9.4) were enrolled. The computer-based neurocognitive tool applied included 11 subtests covering attention (M3), short- and long-term memory (recall and delayed recall), working memory (0- and 2-back, Operation Span [OSPAN] task), processing speed (Trail Making Test [TMT] A), mental flexibility (TMT B), inhibition (cFlanker and iFlanker), and verbal fluency. CI patients underwent a neurocognitive testing preoperatively as well as 12 months postoperatively. Impact of hearing status, age, gender, and education on cognitive subdomains was studied. Additionally, after controlling for education and age, cognitive performance of CI subjects (n = 41) was compared to that of NH (n = 34). Results: CI users achieved significantly better neurocognitive scores 12 months after cochlear implantation than before in most subtests (M3, [delayed] recall, 2-back, OSPAN, iFlanker, and verbal fluency; all p < 0.05) except for the TMT A and B. A significant correlation could be found between the postoperative improvement in speech perception and in the attentional task M3 (p = 0.01). Hearing status (p = 0.0006) had the strongest effect on attention, whereas education had a high impact on recall (p = 0.002), OSPAN (p = 0.0004), and TMT A (p = 0.005) and B (p = 0.003). Inhibition was mainly age-dependent with better results in younger subjects (p = 0.016). Verbal fluency was predicted by gender as females outperformed men (p = 0.009). Even after controlling for age and education NH subjects showed a significantly better performance than CI candidates in the recall (p = 0.03) and delayed recall (p = 0.01) tasks. Postoperatively, there was no significant difference between the 2 groups anymore. Conclusion: Impact of cochlear implantation on neurocognitive functions differs according to the cognitive subdomains. Postoperatively, CI recipients performed as good as age- and education-matched NH subjects.

“…76 Visual stimuli have been developed for the application in subjects with hearing loss, such as in the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing-Impaired Individuals (RBANS-H), the Cambridge Neuropsychological Test Automated Battery (CANTAB), the ALAcog and the Cogstate battery which have mainly been used in the past to study the benefit of cochlear implantation for cognitive functions in older subjects. 50,[77][78][79][80] However by using visual stimuli instead of auditory stimuli different ways of processing might be assessed and a combined audiovisual presentation of stimuli might even alter the performance.…”
