Self-reported hearing difficulties are associated with loneliness, depression and cognitive dysfunction during the COVID-19 pandemic

Speech-evoked cortical activities and speech recognition in adult cochlear implant listeners: a review of functional near-infrared spectroscopy studies

Cochlear implants (CIs) are the most successful neural prostheses, enabling individuals with severe to profound hearing loss to access sounds and understand speech. While CI has demonstrated success, speech perception outcomes vary largely among CI listeners, with significantly reduced performance in noise. This review paper summarizes prior findings on speech-evoked cortical activities in adult CI listeners using functional near-infrared spectroscopy (fNIRS) to understand (a) speech-evoked cortical processing in CI listeners compared to normal-hearing (NH) individuals, (b) the relationship between these activities and behavioral speech recognition scores, (c) the extent to which current fNIRS-measured speech-evoked cortical activities in CI listeners account for their differences in speech perception, and (d) challenges in using fNIRS for CI research. Compared to NH listeners, CI listeners had diminished speech-evoked activation in the middle temporal gyrus (MTG) and in the superior temporal gyrus (STG), except one study reporting an opposite pattern for STG. NH listeners exhibited higher inferior frontal gyrus (IFG) activity when listening to CI-simulated speech compared to natural speech. Among CI listeners, higher speech recognition scores correlated with lower speech-evoked activation in the STG, higher activation in the left IFG and left fusiform gyrus, with mixed findings in the MTG. fNIRS shows promise for enhancing our understanding of cortical processing of speech in CI listeners, though findings are mixed. Challenges include test-retest reliability, managing noise, replicating natural conditions, optimizing montage design, and standardizing methods to establish a strong predictive relationship between fNIRS-based cortical activities and speech perception in CI listeners.

Self-reported hearing loss and health during a pandemic: Findings from a cross-sectional analysis using a 2021 household survey

BACKGROUND

The COVID-19 pandemic differentially impacted individuals with hearing loss, likely in part due to increased communication difficulties from masking, a commonly implemented protective measure.

OBJECTIVE

This study examines the association between self-reported hearing loss and health during the pandemic.

METHODS

This study uses data from the COVID-19 Survey collected by the Survey of the Health of Wisconsin from February to March 2021. Hearing loss was defined as self-reported fair or poor hearing. The outcomes were self-reported symptoms of anxiety and depression, separately, and self-reported general health. Multivariable models adjusted for age, gender, and race/ethnicity were used to examine the associations between hearing loss with each outcome. Results are presented as prevalence ratios (PR) with corresponding 95 % confidence intervals (CI).

RESULTS

There were 1857 participants (60.3 % female, 12.9 % non-white) with a mean age of 57.1 years in this cross-sectional study. In multivariable models, individuals with hearing loss (versus none) had higher prevalence of depression (PR: 1.22, 95 % CI: 1.06, 1.39), anxiety (PR: 1.13, 95 % CI: 1.02, 1.27), and self-reported fair or poor health (PR: 2.61, 95 % CI: 1.89, 3.61).

CONCLUSION

Hearing loss was associated with poorer self-reported health during winter 2021 of the COVID-19 pandemic, when mask use in public was newly mandated and vaccines were not widely available to the general public. Further research on the impact of public health policies on vulnerable populations, including those with hearing loss, is warranted. Such research could inform policy decisions that accommodate these populations.

A comparison of psychosocial health among individuals with different levels of hearing ability during the COVID-19 pandemic

OBJECTIVE

This study assessed the impact of the COVID-19 pandemic on psychosocial health among individuals with different levels of hearing ability.

DESIGN

For this cross-sectional study, adults completed an online digits-in-noise test and survey. Participants were categorised into "good", "insufficient", or "poor" hearing groups. Survey questions included topics on depression, anxiety, distress, somatisation, and loneliness levels. Multiple logistic, linear, and negative binomial regressions examined differences in psychosocial health between hearing groups. Moderation analyses identified vulnerable subgroups. Mediation analyses examined mediating effects of pandemic measures on hearing ability and psychosocial health.

STUDY SAMPLE

Eight-hundred and sixty-five adults with or without hearing impairment.

RESULTS

Individuals with poor hearing had a higher odds of having elevated anxiety levels and had higher somatisation levels compared to participants with good hearing. Chronic diseases significantly moderated the relationship between poor hearing ability and loneliness. Difficulties with communicating through facemasks, 1.5 m distance, plastic screens, and during video calls significantly mediated the relationships between hearing ability, anxiety and somatisation.

CONCLUSIONS

Results highlight the elevated anxiety and somatisation levels experienced among individuals with hearing impairment during the COVID-19 pandemic. More awareness is needed of the negative impact pandemic measures can have on psychosocial health during future health crises.

Daily sound exposure of hearing aids users during COVID-19 pandemic in Europe

Introduction

This study aimed to investigate the daily sound exposure of hearing aid (HA) users during the COVID-19 pandemic, with a specific focus on the impact of different governance intervention levels.

Methods

Modern HA technology was employed to measure and compare the sound exposure of HA users in three distinct periods: pre-pandemic, and two 14-day periods during the pandemic, corresponding to varying levels of governance interventions. The study sample comprised a total of 386 HA users in Europe during the pandemic, with daily sound exposure data collected as part of the main dataset.

Results

The results revealed that, during the pandemic, the equivalent continuous sound pressure level (SPL) experienced by HA users decreased, while the signal-to-noise ratio (SNR) increased compared to the pre-pandemic period. Notably, this impact was found to be more pronounced (p < 0.05) when individuals were subjected to stronger governance intervention levels, characterized by lower SPL and higher SNR.

Discussion

This study highlights the changes in daily sound exposure experienced by HA users during the COVID-19 pandemic, particularly influenced by the extent of governance interventions that restricted social activities. These findings emphasize the importance of considering the effects of pandemic-related governance measures on the sound environments of HA users and have implications for audiological interventions and support strategies during similar crises.

The Impact of Age and Psychosocial Factors on Cognitive and Auditory Outcomes During the COVID-19 Pandemic

PURPOSE

In March 2020, the U.K. government announced that people should isolate to reduce the spread of the virus that causes COVID-19. Outside a pandemic, psychosocial factors, such as socialization and mental health, may impact the relationship between hearing loss and increased dementia risk. We aim to report the impact of psychosocial factors, including social isolation, depression, and engagement in activities, on hearing and cognitive function in younger and older adults during the COVID-19 pandemic.

METHOD

An online survey and experiment assessed self-reported psychosocial factors, self-reported hearing ability and speech-in-noise perception, and cognition. Data were collected between June 2020 and February 2021. Older (n = 112, Mage = 70.08) and younger (n = 121, Mage = 20.52) monolingual speakers of English, without any language or neurological disorders participated. Multiple linear regression models were employed to investigate hypothesized associations between psychosocial factors, and hearing and cognition, in older and younger adults.

RESULTS

Multiple regression analyses indicated that older adults displayed poorer speech-in-noise perception and poorer performance on one of four cognitive tasks, compared with younger adults; increased depression was associated with poorer subjective hearing. Other psychosocial factors did not significantly predict hearing or cognitive function.

CONCLUSIONS

Data suggest that self-reported hearing and depression are related. This conclusion is important for understanding the associations between hearing loss and cognitive decline in the long term, as both hearing loss and depression are risk factors for dementia.

Incidence and persistence of psychological distress during the COVID-19 pandemic among individuals with and without disability

OBJECTIVES

We investigated the incidence (becoming distressed at the follow-up) and persistence (distressed at the baseline and the follow-up) of psychological distress among individuals with and without disability in the period from early 2017 (before the COVID-19 pandemic) to late 2020 (the second wave of the pandemic).

METHODS

We analyzed the population-based FinHealth 2017 survey and its follow-up conducted in 2020 (number of individuals who participated in both surveys: n = 4881; age = 18+). Logistic regressions were applied to investigate differences in the incidence and persistence of psychological distress between people with and without disability. We also investigated whether age, quality of life at the baseline, and perceived increase in loneliness during the COVID-19 pandemic moderated the association between disability and the incidence of distress.

RESULTS

The incidence of psychological distress was higher (OR = 3.01, 95% CI:2.09-4.35) for people with disability (18.9%) than among those without (7.4%), being highest (31.5%) among the youngest participants with disability, aged 18 to 39. People with disability who had a poor quality of life at the baseline were particularly prone to become distressed during the follow-up. People who reported perceived increase in loneliness during the pandemic were prone to become distressed at the follow-up regardless of their disability status. The persistence of distress was more common (OR = 6.00, 95% CI:3.53-10.12) among people with disability (65.7%) than among those without (24.9%).

CONCLUSION

The COVID-19 pandemic had more negative mental health effects on people with disability, especially adults with disability who were young and had a low quality of life before the pandemic.

Hearing loss and depressive symptoms in older Chinese: whether social isolation plays a role

Background

Existing evidence links hearing loss to depressive symptoms, with the extent of association and underlying mechanisms remaining inconclusive. We conducted a cross-sectional study to examine the association of hearing loss with depressive symptoms and explored whether social isolation mediated the association.

Methods

Eight thousand nine hundred sixty-two participants from Guangzhou Biobank Cohort Study were included. Data on self-reported hearing status, the 15-item Geriatric Depression Scale (GDS-15), social isolation and potential confounders were collected by face-to-face interview.

Results

The mean (standard deviation) age of participants was 60.2 (7.8) years. The prevalence of poor and fair hearing was 6.8% and 60.8%, respectively. After adjusting for age, sex, household income, education, occupation, smoking, alcohol use, self-rated health, comorbidities, compared with participants who had normal hearing, those with poor hearing (β = 0.74, 95% confidence interval (CI) 0.54, 0.94) and fair hearing (β = 0.59, 95% CI 0.48, 0.69) had higher scores of GDS-15. After similar adjustment, those with poor hearing (odds ratio (OR) = 2.13, 95% CI 1.65, 2.74) or fair hearing (OR = 1.68, 95% CI 1.43, 1.99) also showed higher odds of depressive symptoms. The association of poor and fair hearing with depressive symptoms attenuated slightly but not substantially after additionally adjusting for social isolation. In the mediation analysis, the adjusted proportion of the association mediated through social isolation was 9% (95% CI: 6%, 22%).

Conclusion

Poor hearing was associated with a higher risk of depressive symptoms, which was only partly mediated by social isolation. Further investigation of the underlying mechanisms is warranted.

Differences in Unfavorable Lifestyle Changes during the COVID-19 Pandemic between People with and without Disabilities in Finland: Psychological Distress as a Mediator

We investigated whether people with disabilities—cognition, vision, hearing, mobility, or at least one of these disabilities—report more COVID-19-related negative lifestyle changes than those without disabilities, and whether psychological distress (MHI-5) mediates the association between disabilities and negative lifestyle changes. Information about COVID-related lifestyle changes among people with disabilities is scarce. We analyzed population-based data from the 2020 FinSote survey carried out between September 2020 and February 2021 in Finland (n = 22,165, aged 20+). Logistic regressions were applied to investigate the effect of the COVID-19 pandemic and related restrictions on negative lifestyle changes—sleeping problems or nightmares, daily exercise, vegetable consumption, and snacking. To test for a mediation effect of psychological distress, the Karlson–Holm–Breen method was used. People with all disability types reported increased sleeping problems or nightmares, and decreased vegetable consumption during the pandemic more frequently than those without. People with mobility and cognitive disabilities more frequently reported decreased daily exercise. People with cognitive disabilities more often reported increased snacking. Psychological distress mediated associations between disabilities and negative lifestyle changes, with the highest association between cognitive disabilities and increased sleeping problems or nightmares (B = 0.60), and the lowest between mobility disabilities and decreased daily exercise (B = 0.08). The results suggest that strategies to promote healthy lifestyles should consider people with disabilities. Alleviating their psychological distress during crisis situations could be one approach.

Adults With Hearing Loss Demonstrate Resilience During COVID-19 Pandemic: Applications for Postpandemic Services

BACKGROUND

The COVID-19 pandemic has produced unique challenges for persons with hearing loss. There is a unique concern that adults with hearing loss may be more susceptible to isolation than adults with normal hearing.

PURPOSE

This study explored the impact of the COVID-19 pandemic on the well-being of older adults with and without hearing loss.

RESEARCH DESIGN

This was a longitudinal study with pre-COVID-19 and six mid-COVID-19 interviews, spanning from March 1, 2020, to October 31, 2020.

STUDY SAMPLE

The study enrolled 12 participants with hearing aids and 12 with cochlear implants aged 55-80 years that were compared to 18 age-matched adults with hearing within normal limits.

DATA COLLECTION AND ANALYSIS

Surveys were completed to evaluate the impact of time alone and loneliness, social contact, depression, and the impact of masks on hearing. A mixed-effects statistical model was used to analyze each question.

RESULTS

Participants commonly reported stress and anxiety during monthly video calls. Adults with varying degrees of hearing loss reported decreased social interaction and increased stress during the pandemic, similar to the rates observed by participants with healthy hearing. Face coverings were commonly reported to affect the intelligibility of conversational speech. Participants with hearing loss found satisfactory methods for maintaining social connection during the pandemic that they hope will continue once restrictions ease fully.

CONCLUSIONS

Participants from the hearing loss groups in this study were frustrated by challenges posed by facial masks and were resilient in their ability to cope with COVID-19 and found the use of technology to be helpful. Audiologists are encouraged to use these successful electronic means of connecting with their patients even after restrictions are fully lifted.

The Impact of Social Isolation Due to COVID-19 on Symptom Progression in People With Dementia: Findings of the SOLITUDE Study

BACKGROUND

People with dementia (PWD) are vulnerable to abrupt changes to daily routines. The lockdown enforced on the 23rd of March 2020 in the UK to contain the expansion of the COVID-19 pandemic limited opportunities for PWD to access healthcare services and socialise. The SOLITUDE study explored the potential long-term effects of lockdown on PWD's symptoms and carers' burden.

METHODS

Forty-five carers and 36 PWD completed a telephone-based assessment at recruitment (T0) and after 3 (T1) and 6 months (T2). PWD completed measures validated for telephonic evaluations of cognition and depression. Carers completed questionnaires on their burden and on PWD's health and answered a customised interview on symptom changes observed in the initial months of lockdown. Longitudinal changes were investigated for all outcome variables with repeated-measures models. Additional post hoc multiple regression analyses were carried out to investigate whether several objective factors (i.e., demographics and time under social restrictions) and carer-reported symptom changes observed following lockdown before T0 were associated with all outcomes at T0.

RESULTS

No significant changes were observed in any outcomes over the 6 months of observations. However, post hoc analyses showed that the length of social isolation before T0 was negatively correlated with episodic and semantic memory performance at T0. Carers reporting worsening of neuropsychiatric symptoms and faster disease progression in PWD also reported higher burden. Moreover, carer-reported worsening of cognitive symptoms was associated with poorer semantic memory at T0.

CONCLUSION

PWD's symptoms and carers' burden remained stable over 6 months of observation. However, the amount of time spent under social restrictions before T0 appears to have had a significant detrimental impact on cognitive performance of patients. In fact, carer-reported cognitive decline during social isolation was consistent with the finding of poorer semantic memory, a domain sensitive to progression in Alzheimer's disease. Therefore, the initial stricter period of social isolation had greater detrimental impact on patients and their carers, followed then by a plateau. Future interventions may be designed to maintain an optimal level of social and cognitive engagement for PWD in challenging times, to prevent abrupt worsening of symptoms and associated detrimental consequences on patients' carers.

The effects of the COVID-19 pandemic on the psychosocial well-being of people with disabilities

Background

Before the COVID-19 pandemic, people with mobility, vision, hearing, and cognitive disabilities were at a higher risk of lower psychosocial well-being than people without disabilities. It is, therefore, of great importance to investigate whether the pandemic has exacerbated this difference.

Objective

This study examines whether people with disabilities (categorized as mobility, vision, hearing, cognitive, and any disabilities) report more COVID-19-related negative effects on psychosocial well-being (loneliness, decreased social contact, decreased hope for the future, concerns about being infected) than people without disabilities.

Methods

We analyzed population-based data from the Finnish Health, Welfare, and Services (FinSote) survey carried out in 2020–2021 (N = 22 165, age 20+). Logistic regression models were applied, controlling for the effects of age, sex, partnership, living alone, and education.

Results

All disability groups, except those with vision disabilities, reported significantly more often that the pandemic increased loneliness than people without disabilities. There were no significant differences between the disability groups and people without disabilities in decreased social contacts. People with only mobility and cognitive disabilities reported significantly more often that the pandemic decreased their hope for the future than those without disabilities. All disability groups were more often concerned about being infected than people without disabilities, but this effect was not significant among people 75 or older.

Conclusion

The psychosocial well-being of people with specific types of disabilities should receive special attention during crises like the COVID-19 pandemic.

The impact of face masks on the communication of adults with hearing loss during COVID-19 in a clinical setting

OBJECTIVE

The aim of the study was to investigate the effect of surgical masks and face shields on speech intelligibility of adults with moderate to severe hearing loss.

DESIGN

This study measured speech tracking scores in quiet for life speech in three different conditions: without a mask, with a surgical mask and with a face shield. Acoustic effects of the masks and face shields on the speech signal were also investigated. Study sample: The study sample consists of 42 patients with moderate to severe hearing loss, 23 cochlear implant users and 19 hearing aid users.

RESULTS

A significant average difference in speech perception scores was found for the use of a surgical mask compared to the listening situation "without mask". The worse the speech understanding in quiet, the larger the impact of the surgical mask. For the worse performers even the face shield had a negative impact on speech perception. The sound distortion for the face shield compared to the surgical mask was greater.

CONCLUSION

This study shows that even for speech perception in quiet, surgical face masks, and face shields to a lesser extent, have a negative effect for patients with moderate to severe hearing loss.
