A growing interest in cognitive effects associated with speech and hearing processes is spreading throughout the scientific community essentially guided by evidence that central and peripheral hearing loss is associated with cognitive decline. For the present research, 125 participants older than 65 years of age (105 with hearing impairment and 20 with normal hearing) were enrolled, divided into 6 groups according to their degree of hearing loss and assessed to determine the effects of the treatment applied. Patients in our research program routinely undergo an extensive audiological and cognitive evaluation protocol providing results from the Digit Span test, Stroop color-word test, Montreal Cognitive Assessment and Geriatric Depression Scale, before and after rehabilitation. Data analysis was performed for a cross-sectional and longitudinal study of the outcomes for the different treatment groups. Each group demonstrated improvement after auditory rehabilitation or training on short- and long-term memory tasks, level of depression and cognitive status scores. Auditory rehabilitation by cochlear implants or hearing aids is effective also among older adults (median age of 74 years) with different degrees of hearing loss, and enables positive improvements in terms of social isolation, depression and cognitive performance.

A number of studies have demonstrated a significant association between age-related hearing loss (ARHL) and cognitive decline. However their relationship is not clear. In this review, we focused on the etiological mechanisms between ARHL and cognitive decline to explain the nature of this relationship: 1) causal mechanisms (e.g., cognitive load hypothesis, cascade hypothesis); 2) common cause mechanisms (e.g., microvascular disease); 3) overdiagnosis or harbinger hypothesis. We conclude that no single mechanism is sufficient and hearing and cognition related to each other in several different ways. In addition, we reviewed the effectiveness of hearing intervention (e.g., hearing aids and cochlear implants) on cognition function, and the role of hearing aid use and cochlear implant depends on the relevant mechanism.

ABSTRACTBackground:Hearing loss can impair effective communication between caregivers and individuals with cognitive impairment. However, hearing loss is not often measured or addressed in care plans for these individuals. The aim of this study is to measure the prevalence of hearing loss and the utilization of hearing aids in a sample of individuals with cognitive impairment in a tertiary care memory clinic.Methods:A retrospective review of 133 charts of individuals >50 years who underwent hearing assessment at a tertiary care memory clinic over a 12-month period (June 2014–June 2015) was undertaken. Using descriptive statistics, the prevalence of hearing loss was determined and associations with demographic variables, relevant medical history, cognitive status, and hearing aid utilization were investigated.Results:Results indicate that hearing loss is highly prevalent among this sample of cognitively impaired older adults. Sixty percent of the sample had at least a mild hearing loss in the better hearing ear. Among variables examined, age, MMSE, and medical history of diabetes were strongly associated with hearing impairment. Hearing aid utilization increased in concordance with severity of hearing loss, from 9% to 54% of individuals with a mild or moderate/severe hearing loss, respectively.Conclusions:Hearing loss is highly prevalent among older adults with cognitive impairment. Despite high prevalence of hearing loss, hearing aid utilization remains low. Our study highlights the importance of hearing evaluation and rehabilitation as part of the cognitive assessment and care management plan in this vulnerable population.

Hearing loss may affect critical domains of health and functioning in older adults. This article describes the rationale and design of the Studying Multiple Outcomes After Aural Rehabilitative Treatment (SMART) study, which was developed to determine to what extent current hearing rehabilitative therapies could mitigate the effects of hearing loss on health outcomes. One hundred and forty-five patients ≥50 years receiving hearing aids (HA) or cochlear implants (CI) were recruited from the Johns Hopkins Department of Otolaryngology-HNS. A standardized outcome battery was administered to assess cognitive, social, mental, and physical functioning. Of the 145 participants aged 50 to 94.9 years who completed baseline evaluations, CI participants had significantly greater loneliness, social isolation, and poorer hearing and communicative function compared with HA participants. This study showed that standardized measures of health-related outcomes commonly used in gerontology appear sensitive to hearing impairment and are feasible to implement in clinical studies of hearing loss.

Abstract Background Globally, about 50 million people were living with dementia in 2015, with this number projected to triple by 2050. With no cure or effective treatment currently insight, it is vital that factors are identified which will help prevent or delay both age-related and pathological cognitive decline and dementia. Observational data have suggested that hearing loss is a potentially modifiable risk factor for dementia, but no conclusive evidence from randomised controlled trials is currently available. Methods The HearCog trial is a 24-month, randomised, controlled clinical trial aimed at determining whether a hearing loss intervention can delay or arrest the cognitive decline. We will randomise 180 older adults with hearing loss and mild cognitive impairment to a hearing aid or control group to determine if the fitting of hearing aids decreases the 12-month rate of cognitive decline compared with the control group. In addition, we will also determine if the expected clinical gains achieved after 12 months can be sustained over an additional 12 months and if losses experienced through the non-correction of hearing loss can be reversed with the fitting of hearing aids after 12 months. Discussion The trial will also explore the cost-effectiveness of the intervention compared to the control arm and the impact of hearing aids on anxiety, depression, physical health and quality of life. The results of this trial will clarify whether the systematic correction of hearing loss benefits cognition in older adults at risk of cognitive decline. We anticipate that our findings will have implications for clinical practice and health policy development.

Abstract Age-related hearing loss (ARHL) is common and a known risk factor for social disengagement in later life. This study explored social functioning following a diagnosis of ARHL. Using a constructivist grounded theory approach we developed an interview schedule to advance a grounded theory from data collected from six older adults who used either hearing aids or cochlear implants. Interview questions concerned social functioning as well as focusing on their perspective of the impact of ARHL on cognitive functioning. We describe a grounded theory conceived as ‘Reconnecting to Others’. This theory posits that participants faced social challenges in relation to their ARHL, and resolved these challenges partly through the use of hearing aids and cochlear implantation. The theory also emphasises the importance of help from other hearing aid users for new users, and corroborates prior findings about strategies older adults with ARHL use to cope with their hearing impairment in various social situations. Once hearing aids and cochlear implants are used and adapted to with the help of peers, participants completed their journey by helping others who had received diagnoses of ARHL. Additionally, participants spoke of the pleasure of hearing again. Interestingly, no participant felt that their ARHL had impacted their cognitive functioning. Our theory provides a basis for explaining existing quantitative findings as well as creating new hypotheses for future testing.

<p class="Normal1" align="left">It is known that the development of auditory skills in children with hearing loss, who use assistive listening devices, requires training and practice. The aims of this research were a) to describe an auditory training software developed in order to help children with cochlear implants and/or hearing aids improve their auditory skills and monitor their performance,  and b) to demonstrate the usability of the auditory training tool. The software is mobile-based and uses VR (Virtual Reality) and Immersive technology. In order to use it, the user must wear a VR headset. This technology was adopted because these devices are considered to be innovative, and are especially popular among children. The software was tested on fourteen hearing-impaired children. Eleven of these children use a cochlear implant and three use hearing aids. The results of this research show that the children with hearing loss were able to play the game successfully. This positive outcome supports the use of VR and Immersive technology as Auditory Training Tools.</p>

Purpose The purpose of this systematic review was to assess studies of treating hearing loss in older adults with cognitive impairment. Of interest to this review is identifying clinical adaptations that may be used to tailor hearing loss treatment to older adults with cognitive impairment in order to better serve this vulnerable population. Method A systematic search with controlled vocabulary and key word terms was applied to PubMed, the Cochrane Library, Embase, CINAHL, and PsycINFO. Search concepts included terms related to hearing loss and cognitive impairment. The overall search resulted in 4,945 unique references, 50 of which were eligible for full-text review and 13 of which were included in the final review. Included manuscripts were categorized according to the American Speech-Language-Hearing Association's levels of evidence and the National Institutes of Health Quality Assessment Tools. Results Only 1 study implemented a randomized controlled trial design to assess cognitive function and behavioral symptoms after treatment with hearing aids. Other quasiexperimental studies evaluated dementia-related symptoms and/or auditory function after treating hearing loss in pre/post research designs. Finally, evidence from case studies suggested that hearing loss treatment is feasible, reduces stressful communication for caregivers, and improves dementia-related behavior problems. Conclusion Based on the systematic review, evidence suggests that treating hearing loss in persons with cognitive impairment can have benefits to communication and quality of life. Because of the quasi- and nonexperimental nature of most of the evidence found in this review, further studies are necessary to understand the effect of treatment in the context of a variable and progressive disease.

Introduction: The aims of this study were to examine the validity of self-perceived hearing loss in detecting hearing loss and factors associated with self-perceived hearing loss and hearing-help seeking and to report hearing aid adoption among a group of community-dwelling older adults in Malaysia. Methods: A total of 301 older adults (⩾60 years of age) participating in a study on aging had their hearing tested using pure-tone audiometry. Self-perceived hearing loss was assessed using a single question. Sociodemographic profile, otologic history, and general cognitive status were also obtained. Results: A single question had low sensitivity in detecting actual hearing loss: 31.3% for 4-frequency average > 25 dBHL and 48.8% for 4-frequency average > 40 dBHL. Besides hearing level, history of otorrhea and tinnitus were factors that were associated with self-perceived hearing loss among older adults with at least mild hearing loss. Hearing-help-seeking behavior was not associated with any of the tested variables. The hearing aid adoption rate was 2.7% and 7.3% among participants with 4-frequency averages > 25 dBHL and > 40 dBHL, respectively. Conclusion: The underestimation of hearing loss in the majority of older adults in this study poses a potential barrier to hearing loss intervention.
