Article Abstract
Background: Hearing loss is an important factor affecting cognitive function in the elderly. However, the relationship between hearing loss, social isolation, and cognitive function remains unknown. This study aims to explore the relationship between hearing loss and cognitive function in the elderly and analyze the mediating role of social isolation.
Method: From June to November 2023, a total of 450 elderly people (Male 161, Female 289) were recruited in Tangshan City by convenience sampling, including 252 young-old, 168 middle-old, and 30 very old. The study used the general demographic questionnaire, hearing handicap inventory for the elderly-screening (HHIE-S), Montreal Cognitive Assessment (MoCA), and Lubben social network scale (LSNS-6) to collect cross-sectional data from the elderly participants. Data analysis was performed using SPSS 24.0 and PROCESS macro.
Result: The mean age of older adults was 72.77 ± 7.96years, ranging from 60 to 87 years old. The hearing loss score of the elderly was 10.00 ± 7.75 points, the cognitive function score was 24.06 ± 4.22 points, and the social isolation score was 15.73 ± 4.83 points. A negative correlation was observed between hearing loss and cognitive function in the elderly (=-0.418, < 0.001). In addition, hearing loss was also negatively correlated with social isolation in the elderly (=-0.385, < 0.001). However, a positive correlation was found between social isolation and cognitive function ( = 0.537, < 0.001). Furthermore, hearing loss in the elderly was found to not only directly affect their cognitive function but also indirectly affect their cognitive function through the mediating effect of social isolation, with a mediating effect value of -0.170.
Conclusion: This study revealed that hearing loss, social isolation and cognitive function in the elderly are not optimistic. Hearing loss can not only directly affect cognitive function but also indirectly affect cognitive function through the mediating effect of social isolation.

The human auditory system must distinguish relevant sounds from noise. Severe hearing loss can be treated with cochlear implants (CIs), but how the brain adapts to electrical hearing remains unclear. This study examined adaptation to unilateral CI use in the first and seventh months after CI activation using speech comprehension measures and electroencephalography recordings, both during passive listening and an active spatial listening task.

Background: Hearing loss (HL) is one of the most common congenital anomalies and is a complex etiologically diverse condition. Molecular genetic characterization of HL remains challenging owing to the high genetic heterogeneity. This study aimed to screen for potential disease-causing genetic variations in a cohort of Indian patients with congenital bilateral severe-to-profound sensorineural HL.

Objective: To investigate the characteristics of brain structures in patients with noise-induced hearing loss (NIHL) using source-based morphometry (SBM) and to evaluate the correlation between abnormal brain regions and clinical data.
Methods: High-resolution 3D T1 structural images were acquired from 81 patients with NIHL and 74 age- and education level-matched healthy controls (HCs). The clinical data of all subjects were collected, including noise exposure time, monaural hearing threshold weighted values (MTWVs), Mini-Mental State Examination (MMSE), and Hamilton Anxiety Scale (HAMA) scores.
