Dual- and Single-Task Training in Older Adults With Age-Related Hearing Loss: A Randomized Controlled Study.

We aimed to investigate the effects of dual- and single-task training in older adults with age-related hearing loss. Intervention groups included single-, dual-task training, and control groups. The dual- and single-task trainings were held 2 days a week for 40 min for a total of 10 sessions for 5 weeks. We evaluated physical, cognitive, and auditory functions, quality-of-life, balance, concerns about falling, independence in activities of daily living, and dual-task performance. A total of 42 patients fully participated in this study. Statistically significant differences were observed in chair stand, chair sit-and-reach, global cognitive function, and delayed recall between the intervention groups and control group (p < .05). There was no statistically significant difference in quality-of-life, balance, falling concerns, independence in activities of daily living, and dual-task performance between all groups (p > .05). In conclusion, single- and dual-task training had a positive effect on physical and cognitive functioning in older adults with age-related hearing loss.

[Early management of presbycusis: recommendations from the French Society of Otorhinolaryngology and Head and Neck Surgery, the French Society of Audiology, and the French Society of Geriatrics and Gerontology]. / Recommandations de la Société française d'otorhinolaryngologie et de chirurgie de la face et du cou, la Société française d'audiologie et la Société française de gériatrie et gérontologie pour la prise en charge précoce de la presbyacousie.

INTRODUCTION: Presbycusis is the physiological decrease in hearing due to advancing age and begins well before the sixth decade. These recommendations recall the principles of early diagnosis of presbycusis and the means of optimal rehabilitation as soon as the first symptoms appear. MATERIAL AND METHODS: The recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of doctors and audioprosthetists from all over France. They are graded A, B, C or expert opinion according to decreasing level of scientific evidence. RESULTS: The diagnosis of presbycusis is more difficult at the beginning of its evolution but a certain number of tools are available for its early diagnosis and its management in face-to-face or even distance learning. CONCLUSION: In case of a clinical profile suggestive of presbycusis in a young subject, especially if there are several family cases, it is recommended to propose a genetic investigation. It is recommended to perform free-field speech audiometry in noise to measure intelligibility in an environment as close as possible to reality. Questionnaires can be used in addition to audiometry to best assess the patient's disability. It is recommended that hearing rehabilitation with a hearing aid or cochlear implant may slow or prevent cognitive decline. Combined auditory and cognitive rehabilitation should be offered regardless of the time elapsed since the fitting. It is recommended to integrate programs accessible via smartphones, tablets or the Internet, integrating different training domains in addition to face-to-face sessions.

The Effect of Monaurally Fitted Hearing Aid Use on the Evolution of Presbycusis.

OBJECTIVE: The effect of hearing aid use on the evolution of presbycusis has not been well described in the literature, with only a handful of publications addressing this topic. This paper aims to evaluate the long-term use of amplification and its effect on pure-tone thresholds and word recognition scores. METHOD: Monaurally fitted patients were followed with serial audiograms. Data was collected from hearing aid centers. Seventy-seven patients with presbycusis met the inclusion criteria and participated in the present study. The progression of hearing loss in both pure tone thresholds and word recognition scores were compared between the hearing aid ears (HA), and the non-hearing aid ears (NHA). Pure tone thresholds were analyzed by comparing the pure tone average at the initial and last audiograms. Word Recognition Scores (WRS) were analyzed using the model of Thornton and Raffin (1978), and by comparing the change in the absolute values of WRS from the initial to the last audiogram between the HA ear and the NHA ear. RESULTS: No significant difference in pure-tone thresholds between the HA ear and NHA ear was found at the last audiogram (P = .696), even after dividing the patients into groups based on the duration of amplification. Both methods of analysis of patients' WRS showed a statistically significant worsening in NHA (P < .05). CONCLUSION: The present study supports the previously defined auditory deprivation effect on non-fitted ears, which showed worsening of word recognition over time and no effect on pure tone average. It provides an additional argument for the counseling of patients with presbycusis considering amplification, and highlights the importance of bilateral amplification in preserving the residual hearing of hearing impaired patients.

[Do hearing aids live up to their promises?] / Doen hoortoestellen wel wat ze beloven?

The main type of acquired hearing impairment is presbycusis (age-related hearing impairment). In presbycusis, mainly the high tones are no longer heard properly. In the Netherlands, approximately 2 million people are hard of hearing. About one third of all hearing impaired people have 1 or 2 hearing aids. 90% of the group of hearing aid users consists of people over 65. 15% of hearing aid users never or rarely use their hearing aid. The main complaint of hearing aid users is a reduced understanding of speech in noise. When the hearing impaired start to avoid a noisy setting, this can lead to symptoms of sadness and loneliness. Hearing aids live only partially up to promises. Both more information about hearing aids and more support for hearing aid users are necessary to achieve greater satisfaction.

LoCHAid: An ultra-low-cost hearing aid for age-related hearing loss.

Hearing aids are the primary tool in non-medical rehabilitation for individuals with hearing loss. While the costs of the electronic components have reduced substantially, the cost of a hearing aid has risen steadily to the point that it has become unaffordable for the majority of the population with Age-Related Hearing Loss (ARHL) especially for those residing in low- and middle-income countries. Here, we present an ultra-low-cost, affordable and accessible hearing aid device ('LoCHAid'), specifically targeted towards treating ARHL in elderly patients. The LoCHAid components cost 98 cents (< $1) when purchased in bulk for 10,000 units and can be personalized for each user through a 3D-printable case. It is designed to be an over-the-counter (OTC) self-serviceable solution for elderly individuals with ARHL. Electroacoustic measurements show that the device meets most of the targets set out by the WHO Preferred Product Profile and Consumer Technology Association for hearing aids. The frequency response of the hearing aid shows selectable gain in the range of 4-8 kHz, and mild to moderate gain between 200-1000 Hz, and shows very limited total distortion (1%). Simulated gain measurements show that the LoCHAid is well fitted to a range of ARHL profiles for males and females between the ages of 60-79 years. Overall, the measurements show that the device offers the potential to benefit individuals with ARHL. Thus, our proposed design has the potential to address the challenge of affordable and accessible hearing technology for hearing impaired elderly individuals especially in low- and middle-income countries.

Factors associated with the efficiency of hearing aids for patients with age-related hearing loss.

OBJECTIVE: The aim of this study was to investigate the satisfaction of age-related hearing loss (ARHL) or presbycusis patients with individual, accurate, and precise fitting progress, which is a priority for bilateral hearing aids, and to explore the related influencing factors and their role in predicting the efficiency of hearing aids. METHODS: A total of 73 cases of presbycusis patients aged 60-95 years old underwent pure tone audiometry and speech recognition ability examination to obtain the pure tone audiometry of the better ear (BPTA) and maximum speech recognition rate of the better ear (BSRR) in quiet environment before hearing aid fitting. Audiologists evaluated the efficiency and satisfaction of participants according to the International Outcome Inventory for Hearing Aids (IOI-HA) questionnaire scores by face-to-face or telephone investigations after using the hearing aids for at least 3 months. The data were analyzed related to possible influencing factors. RESULTS: Total satisfaction percentage according to IOI-HA scores was 86.3%. There was no significant correlation between age, first fitting age, unilateral or bilateral hearing aids, BPTA, and IOI-HA total score. BSRR was strongly correlated to total IOI-HA scores (r=0.768). According to the multiple linear regression analysis, BPTA and BSRR both had a statistically significant effect on the total IOI-HA scores after hearing aid intervention. CONCLUSION: ARHL patients with accurate hearing aid fitting will have high satisfaction and bilateral hearing aids are better than unilateral ones. Age and first fitting age are not meaningful to satisfaction with hearing aids. A higher maximum speech recognition rate before hearing aids fitting could predict better efficiency and satisfaction with hearing aids. Therefore, completing speech recognition ability examination before fitting would make a great contribution to the efficiency of hearing aids, and help ARHL patients have realistic expectations.

Special Populations in Implantable Auditory Devices: Geriatric.

Hearing loss is common in the geriatric population. Most hearing loss is associated with presbycusis or age-related hearing loss, impacting one-third of individuals over 65 years and increasing in prevalence with age. Hearing loss impacts quality of life, psychological health, and cognition. Implantable auditory devices are an exceptional option to improve hearing and quality of life. Various implantable auditory devices have been implemented safely with significant improvement in communication and performance on auditory tasks. Counseling is essential to establishing realistic expectations. Rehabilitation may be required to optimize outcomes and auditory performance with use.

Prospective Evaluation of Cognitive Functions After Rehabilitation With Cochlear Implant or Hearing Aids: Preliminary Results of a Multicentric Study on Elderly Patients.

Objective Recent literature has shown a growing interest in the relationship between presbycusis and cognitive decline, but significant evidence about the long-term benefit of rehabilitation on cognitive functions has not been reported yet. The aim of the study was to analyze audiological and neuropsychological performances in patients with cochlear implant (CI) or hearing aids (HAs) over time. Materials and Method Forty-four bilaterally deaf patients aged more than 60 years (25 with CI candidacy and 19 with HA candidacy) were enrolled. Patients were subjected to audiological evaluation, to a battery of neuropsychological tests (Mini-Mental State Examination [MMSE], Rey Auditory Verbal Learning Task [RAVLT], Rey-Osterreith Complex Figure Test, Digit/Corsi Span Forward and Backward, Multiple Features Target Cancellation, Trail-Making Test, Stroop Test, and Phonological and Semantic Word Fluency), and to a quality of life assessment (Short Form 36, Glasgow Benefit Inventory, Glasgow Health Status Inventory) at the baseline and after a long-term follow-up (6-12 months). Results Speech recognition scores in quiet and in noise were significantly improved even 6 months after auditory rehabilitation. Significant differences between pre- and post-rehabilitation scores were reported in physical and emotional impacts in life, general global health, vitality, and social activities. MMSE and RAVLT scores were significantly improved in both groups after 6 months of follow-up, suggesting a global involvement of memory domain. Mnesic performances remained unchanged between the first and second follow-up, but a further significant improvement in executive functions (Stroop Test) was detected in patients with CI reevaluated 12 months after implantation. A significant correlation of the RAVLT with signal-to-noise ratio at +10 dB speech-in-noise scores and the MMSE with signal-to-noise ratio at 0 dB speech-in-noise scores suggests the pivotal role of executive functions in recognition in noisy environment. Conclusions Our preliminary data confirm that hearing deprivation in aged patients represents a truly modifiable risk factor for cognitive decline, which can be positively faced by acoustic rehabilitation. The improvement of short- and long-term memory performances and the amelioration of executive and attentive functions suggest that hearing restoration with both HAs and CI may provide a recovery of superior cognitive domains probably through a reallocation of cortical resources altered by hearing deprivation.

Age-related hearing loss and cognitive decline - The potential mechanisms linking the two.

The amount of attention to age-related hearing loss (ARHL) has been growing, not only from the perspective of being one of the most common health conditions affecting older adults, but also from the perspective of its relation to cognition. Results from a number of epidemiological and laboratory studies have demonstrated a significant link between ARHL and cognitive decline. The Lancet International Commission on Dementia, Prevention, Intervention, and Care has estimated that mid-life hearing loss, if eliminated, might decrease the risk of dementia by nine percent, since hearing loss is a modifiable age-associated condition linked to dementia. Despite numerous research efforts, elucidation of the underlying causal relationships between auditory and cognitive decline has not yet reached a consensus. In this review article, we focused on the hypotheses of etiological mechanisms between ARHL and cognitive decline: (1) cognitive load hypothesis; (2) common cause hypothesis; (3) cascade hypothesis; and (4) overdiagnosis or harbinger hypothesis. Factual evidence obtained in previous studies was assessed to understand the link between ARHL and cognitive decline or dementia. Additionally, an overview of the conceivable effects of hearing intervention, e.g., hearing aids and cochlear implants, on cognition were presented, and the role of hearing aid use was considered for the relevant hypotheses. We should continue to strive for social enlightenment towards the importance of 'hearing well', and cultivate a necessity for hearing screening among patients at risk of cognitive decline.

Efectos de un protocolo de tratamiento osteopático sobre la región cervical en pacientes con presbiacusia / No disponible

INTRODUCCIÓN: Las hipoacusias representan una causa frecuente de incapacidad crónica y minusvalía, ya que afectan a más del 20% de la población adulta. Diversos autores hablan de la relación entre los problemas del raquis cervical y los problemas de audición. La vascularización del aparato auditivo está íntimamente relacionada con el raquis cervical, cuyas disfunciones podrían provocar una disminución del aporte sanguíneo, favoreciendo su deterioro y la pérdida de audición. OBJETIVOS: Evaluar los efectos del tratamiento osteopático a nivel cervical sobre los niveles de audición en pacientes con presbiacusia. MATERIAL Y MÉTODOS: Serie de casos con 6 mujeres con presbiacusia y edad media de 51,17 años (±10,48). Se realizó una audiometría y los tests de Rinne y Weber previamente a aplicar el protocolo de tratamiento durante 4 semanas, tras las que se repitió la valoración. RESULTADOS: No hubo diferencias significativas ni en los tests de Rinne derecho/izquierdo (p = 0,296/1,000) y Weber (p = 0,505) ni en la audiometría (p > 0,05 en las diferentes frecuencias) en las evaluaciones post tratamiento. CONCLUSIONES: El protocolo de tratamiento osteopático usado en este estudio no mejoró la capacidad auditiva en pacientes con presbiacusia

The Acoustic Environments in Which Older Adults Wear Their Hearing Aids: Insights From Datalogging Sound Environment Classification.

PURPOSE: This report presents data on the acoustic environments in which older adults with age-related hearing loss wear their hearing aids. METHOD: This is an observational study providing descriptive data from 2 primary datasets: (a) 128 older adults wearing hearing aids for an average of 6 weeks and (b) 65 older adults wearing hearing aids for an average of 13 months. Acoustic environments were automatically and continuously classified about every 4 s, using the hearing aids' signal processing, into 1 of 7 acoustic environment categories. RESULTS: For both groups, older adults wore their hearing aids about 60% of the time in quiet or speech-only conditions. The automatic classification of sound environments was shown to be reliable over relatively short (6-week) and long (13-month) durations. Moreover, the results were shown to have some validity in that the obtained acoustic environment profiles matched a self-reported measure of social activity administered prior to hearing aid usage. For a subset of 56 older adults with data from both the 6-week and 13-month wear times, the daily amount of hearing aid usage diminished but the profile of sound environments frequented by the wearers remained stable. CONCLUSIONS: Examination of the results from the automatic classification of sound environments by the hearing aids of older adults provides reliable and valid environment classifications. The present data indicate that most such wearers choose generally favorable acoustic environments for hearing aid use.

Age-Related Hearing Loss: Innovations in Hearing Augmentation.

Age-related hearing loss is a multifactorial condition that affects more than one-third of the aging population. Left untreated it can increase the risk of cognitive decline, dementia, social isolation, depression, and falls. Hearing augmentation devices exhibit improved digital sound processing and Smartphone connectivity. Stigma remains one of the prominent barriers and todays devices offer in the canal models, miniature sizes, and camouflage with the hair or skin color. Although rigorous scientific efforts are made in the research field of inner ear regeneration and some clinical early phase studies do exist, to date, the clinical availability is still some time away.

Implications of using the Hearing Aids on quality of life of elderly. / Implicações do uso do Aparelho de Amplificação Sonora Individual na qualidade de vida de idosos.

PURPOSE: To evaluate through standardized questionnaires the quality of life of elderly people with hearing loss diagnosed with and without the use of hearing aids (HA) and elderly without hearing complaints. METHODS: This is a cross-sectional study with non probabilistic sample, divided into three groups divided as follows: 30 elderly people with diagnosed hearing loss and indication for use of individual sound amplification devices (hearing aids), but have not yet made use of the prosthesis; 30 individuals with hearing impairment who used hearing aids and 30 elderly without hearing complaints. Participants completed a questionnaire investigating sociodemographic and family data, the Hearing Handicap Inventory for the Elderly Screening Version (HHIE-S) and the World Health Organization Quality of Life - Short version (WHOQOL-BREF). In addition to the descriptive analysis of the data were performed tests to compare the three groups by applying analysis of variance (ANOVA) and the Bonferroni post hoc test. RESULTS: The three groups differed significantly in all domains of quality of life. The group of the elderly people with hearing loss diagnosed and with indication for the use of hearing aids presented lower scores and the group of the elderly with hearing disabilities that used the hearing aid and that the reference group. The AASI group presented the best quality of life results. CONCLUSION: The hearing loss affects the quality of life of the elderly. The effective use of hearing aid is beneficial to this population, improving their living and health conditions.

The impact of hearing aids and age-related hearing loss on auditory plasticity across three months - An electrical neuroimaging study.

The present study investigates behavioral and electrophysiological auditory and cognitive-related plasticity in three groups of healthy older adults (60-77 years). Group 1 was moderately hearing-impaired, experienced hearing aid users, and fitted with new hearing aids using non-linear frequency compression (NLFC on); Group 2, also moderately hearing-impaired, used the same type of hearing aids but NLFC was switched off during the entire period of study duration (NLFC off); Group 3 represented individuals with age-appropriate hearing (NHO) as controls, who were not different in IQ, gender, or age from Group 1 and 2. At five measurement time points (M1-M5) across three months, a series of active oddball tasks were administered while EEG was recorded. The stimuli comprised syllables consisting of naturally high-pitched fricatives (/sh/, /s/, and /f/), which are hard to distinguish for individuals with presbycusis. By applying a data-driven microstate approach to obtain global field power (GFP) as a measure of processing effort, the modulations of perceptual (P50, N1, P2) and cognitive-related (N2b, P3b) auditory evoked potentials were calculated and subsequently related to behavioral changes (accuracy and reaction time) across time. All groups improved their performance across time, but NHO showed consistently higher accuracy and faster reaction times than the hearing-impaired groups, especially under difficult conditions. Electrophysiological results complemented this finding by demonstrating longer latencies in the P50 and the N1 peak in hearing aid users. Furthermore, the GFP of cognitive-related evoked potentials decreased from M1 to M2 in the NHO group, while a comparable decrease in the hearing-impaired group was only evident at M5. After twelve weeks of hearing aid use of eight hours each day, we found a significantly lower GFP in the P3b of the group with NLFC on as compared to the group with NLFC off. These findings suggest higher processing effort, as evidenced by higher GFP, in hearing-impaired individuals when compared to those with normal hearing, although the hearing-impaired show a decrease of processing effort after repeated stimulus exposure. In addition, our findings indicate that the acclimatization to a new hearing aid algorithm may take several weeks.

[Benefit of Bimodal Stimulation with Cochlear Implant and Hearing Aid in Elderly Patients]. / Cochlea-Implantation ab dem 70. Lebensjahr ­ Nutzen der bimodalen Versorgung mit Hörgerät und CI.

Cochlear implant (CI) surgery is the standard of care for postlingual deafness in adults. A hearing aid (HA) for the non-implanted ear is normally used if residual hearing is available. There is limited data on bimodal stimulation in elderly patients. We compare the outcome of bimodal stimulation and analyzed the correlation of bimodal benefit and residual hearing in elderly patients. 22 patients≥70 years were implanted with a single-sided CI from 2002 till 2014. 17 patients use a HA on the non-implanted ear (bimodal). In a retrospective chart review we analyzed the audiological benefit (pure tone average, speech recognition). Time to follow-up was 6 month to 12 years. The subjective benefit was assessed using a structured questionnaire. The speech recognition (monosyllabic word testing in quiet @ 65 dB SPL) showed a score of 61% in bimodal condition vs. 53% with CI alone (p=0.35). There was no statistically significant correlation between residual hearing in the lower frequencies (250 Hz, 500 Hz and 1 kHz) and bimodal benefit. Most elderly patients benefit from bimodal stimulation. In quiet and in comparison with CI alone, most patients showed some improvement in word recognition scores using bimodal fitting, and all of them were using the contralateral hearing aid all day long. Postlingual deafened elderly patients fitted with a unilateral CI require a short rehabilitation period. In case of contralateral hearing aid fitting, regular control of the hearing aid should not be overlooked.

Cross-modal plasticity in developmental and age-related hearing loss: Clinical implications.

This review explores cross-modal cortical plasticity as a result of auditory deprivation in populations with hearing loss across the age spectrum, from development to adulthood. Cross-modal plasticity refers to the phenomenon when deprivation in one sensory modality (e.g. the auditory modality as in deafness or hearing loss) results in the recruitment of cortical resources of the deprived modality by intact sensory modalities (e.g. visual or somatosensory systems). We discuss recruitment of auditory cortical resources for visual and somatosensory processing in deafness and in lesser degrees of hearing loss. We describe developmental cross-modal re-organization in the context of congenital or pre-lingual deafness in childhood and in the context of adult-onset, age-related hearing loss, with a focus on how cross-modal plasticity relates to clinical outcomes. We provide both single-subject and group-level evidence of cross-modal re-organization by the visual and somatosensory systems in bilateral, congenital deafness, single-sided deafness, adults with early-stage, mild-moderate hearing loss, and individual adult and pediatric patients exhibit excellent and average speech perception with hearing aids and cochlear implants. We discuss a framework in which changes in cortical resource allocation secondary to hearing loss results in decreased intra-modal plasticity in auditory cortex, accompanied by increased cross-modal recruitment of auditory cortices by the other sensory systems, and simultaneous compensatory activation of frontal cortices. The frontal cortices, as we will discuss, play an important role in mediating cognitive compensation in hearing loss. Given the wide range of variability in behavioral performance following audiological intervention, changes in cortical plasticity may play a valuable role in the prediction of clinical outcomes following intervention. Further, the development of new technologies and rehabilitation strategies that incorporate brain-based biomarkers may help better serve hearing impaired populations across the lifespan.

A review of new insights on the association between hearing loss and cognitive decline in ageing.

Age-related hearing loss (ARHL) has a multifactorial pathogenesis and it is an inevitable hearing impairment associated with reduction of communicative skills related to ageing. Increasing evidence has linked ARHL to more rapid progression of cognitive decline and incidental dementia. Many aspects of daily living of elderly people have been associated to hearing abilities, showing that hearing loss (HL) affects the quality of life, social relationships, motor skills, psychological aspects and function and morphology in specific brain areas. Epidemiological and clinical studies confirm the assumption of a relationship between these conditions. However, the mechanisms are still unclear and are reviewed herein. Long-term hearing deprivation of auditory inputs can impact cognitive performance by decreasing the quality of communication leading to social isolation and depression and facilitate dementia. On the contrary, the limited cognitive skills may reduce the cognitive resources available for auditory perception, increasing the effects of HL. In addition, hearing loss and cognitive decline may reflect a 'common cause' on the auditory pathway and brain. In fact, some pathogenetic factors are recongised in common microvascular disease factors such as diabetes, atherosclerosis and hypertension. Interdisciplinary efforts to investigate and address HL in the context of brain and cognitive ageing are needed. Surprisingly, few studies have been adressed on the effectiveness of hearing aids in changing the natural history of cognitive decline. Effective interventions with hearing aids or cochlear implant may improve social and emotional function, communication, cognitive function and positively impact quality of life. The aim of this review is to overview new insights on this challenging topic and provide new ideas for future research.
