AI Article Synopsis
- - The study aimed to investigate how hearing aid use affects cognitive function, frailty, anxiety, depression, and quality of life in older adults with hearing loss, given the unresolved nature of this relationship.
- - Conducted at a Hearing Aid Center from 2020 to 2021, the research compared two groups of patients (hearing aid users and non-users) using various assessments, including cognitive tests and questionnaires regarding lifestyle and health conditions.
- - Findings revealed that while hearing aid users tended to be older and had higher rates of hypertension, their cognitive scores (MMSE) did not significantly differ from non-users, suggesting that hearing aid use does not necessarily improve cognitive function in this population.
Article Abstract
Objective: Age-related cognitive decline involves a complex set of factors. Among these factors, hearing loss is considered to have a significant impact, but the effect of hearing aid use remains unresolved. The purpose of this study was to evaluate the effects of hearing aid use by simultaneously assessing various factors not only cognitive function but also frailty, anxiety, depression, and quality of life (QOL) in patients with hearing loss.
Methods: The cross-sectional study at the Hearing Aid (HA) Center was conducted between 2020 and 2021. Initially, associations with cognitive function, QOL, frailty, and mental state among patients with hearing loss were examined, irrespective of whether they wore a hearing aid or not. Next, these patients were divided into HA users (using HA for more than 1 year) and non-users (no prior use of HA) with 42 patients in each group. The average age and 6-frequency pure tone audiometry (PTA) was 74.5 ± 6.5 years and 50.6 ± 12.1 dB, respectively. All participants filled out the questionnaire about their life style, medical condition. Mini-Mental State Examination (MMSE) for cognitive function, Hospital Anxiety and Depression Scale for mental state, Short Form 36 version 2 (SF-36v2) for QOL, and Kihon Checklist for frailty were compared between HA users and non-users and correlated with the auditory data (PTA and speech discrimination).
Results: Among 84 patients, 40 had an MMSE score ≦26. All eight scores and three components of SF-36v2 were lower than those of the control group. The patients with hypertension were significantly more in HA user than in non-HA user, whereas there was no difference in diabetes, heart attack, stroke and education. Although HA users were older and showed hypertension more their PTA was worse than that of non-users, MMSE scores were not different between the groups. MMSE scores correlated with both PTA and speech discrimination in non-users but not in HA users. However, a multivariate analysis of the effect of HA use on MMSE scores adjusting for age, hypertension, and hearing loss, could not be revealed. The vitality and mental component summary of the SF-36v2 was better in HA users than in non-users.
Conclusion: Elderly patients with hearing loss were cognitively impaired and had low QOL. HA users showed better QOL score than non-HA user, especially about the mental condition. The absence of a correlation between MMSE scores and hearing loss in HA users suggests the potential use of HA in preventing cognitive decline.

Background: Hearing rehabilitation has been a promising approach to improve cognitive outcomes. An ongoing study identified some barriers to engage patients in counseling sessions and using their hearing devices. Here we present the results from the first stage of a Sense-Cog Brazil pilot study, the recruitment phase.

Background: Our authors from around the world met to summarise the available knowledge, decide which potentially modifiable risk factors for dementia have compelling evidence and create the most comprehensive analysis to date for potentially modifiable risk factors to inform policy, give individuals the opportunity to control their risks and generate research.
Method: We incorporated all risk factors for which we judged there was strong enough evidence. We used the largest recent worldwide meta-analyses for risk factor prevalence and relative risk and if not available the best data.

Background: The 2020 Lancet Commission on dementia prevention, intervention and care estimated that up to 40% of dementia cases could be prevented by tackling 12 potentially modifiable risk factors, namely less education, hearing loss, hypertension, physical inactivity, diabetes, social isolation, excessive alcohol consumption, air pollution, smoking, obesity, traumatic brain injury, depression. As more evidence on risk factors emerges, the Lancet standing commission on dementia met to update evidence on established dementia risk factors and to consider the evidence for other risk factors.
Method: We used a lifecourse approach to understand how to reduce risk or prevent dementia, as many risks operate at different timepoints in the lifespan.

Background: The dual-cyclical relationship between language and cognition, encapsulated in linguistic relativity, underscores the reciprocal influence of thoughts on communication and vice-versa. This study explores the intricate changes in pragmatics, a fundamental aspect of human communication, during the aging process, considering changes in sensory abilities, cognition, and language.
Method: Sixty participants, aged ≥50 years with a minimum of five years of formal education, were included, excluding those with neurological or psychological illnesses.
The recent ACHIEVE study (https://www.achievestudy.org/) demonstrated the substantial benefit of hearing aid use in those with mild-moderate hearing loss and at increased risk for cognitive decline.
