Enhanced Cochlear Coverage and Hearing Preservation in High-Frequency Hearing Loss via Electric Acoustic Stimulation with Longer Electrode03:49

Enhanced Cochlear Coverage and Hearing Preservation in High-Frequency Hearing Loss via Electric Acoustic Stimulation with Longer Electrode

1.2K
Electric acoustic stimulation (EAS) with longer electrodes can offer broader cochlear coverage and various types of maps in cases of high-frequency hearing loss. Combining less invasive surgery, flexible lateral-wall electrodes, and steroid administration permits deeper insertion with little or no surgical trauma, resulting in good preservation of...

Modified Experimental Conditions for Noise-Induced Hearing Loss in Mice and Assessment of Hearing Function and Outer Hair Cell Damage

2.8K
Here, we present a protocol for a mouse model of noise-induced hearing loss (NIHL). To induce NIHL, we developed a new and simple device using corrugated plastic, a rat trap cage, and a speaker. Auditory brainstem response and immunofluorescence imaging were employed to assess the hearing function and outer hair cell damage,...

Neuro-rehabilitation Approach for Sudden Sensorineural Hearing Loss

19.8K
This article reports the development of a neuro-rehabilitation approach, "constraint-induced sound therapy (CIST)" for sudden sensorineural hearing loss. The aim of CIST is to prevent maladaptive cortical reorganization by using an enriched acoustic environment. CIST represents a safe, easy, inexpensive, and effective approach to treat sudden sensorineural hearing...

Area of Science:

  • Gerontology
  • Neuroscience
  • Audiology

Background:

  • Hearing loss is a prevalent condition in older adults and is increasingly recognized as a potential modifiable risk factor for cognitive decline.
  • Previous research has suggested a link between hearing impairment and cognitive function, but findings have been inconsistent, particularly regarding gender-specific effects.

Purpose of the Study:

  • To investigate the association between hearing loss and cognitive function, stratified by gender, in a nationally representative sample of older adults.
  • To determine if gender moderates the relationship between hearing impairment and global cognitive performance.

Main Methods:

  • Utilized data from the National Health and Nutrition Examination Survey (2010-2011) including 655 participants aged 60-69 years.
  • Assessed cognitive function using the Consortium to Establish a Registry for Alzheimer's disease, Animal Fluency Test, and Digit Symbol Substitution Test, creating a composite z-score.
  • Employed regression models to analyze the association between moderate/severe hearing loss and cognitive function, controlling for potential confounders.

Main Results:

  • Moderate to severe hearing loss was significantly associated with lower global cognitive function scores in males (β = -28.67).
  • This association was not statistically significant in females (β = -8.82), indicating a gender difference.
  • The confidence intervals for males and females did not overlap, supporting the observed gender-specific effect.

Conclusions:

  • Significant gender differences exist in the association between hearing loss and cognitive function among older adults.
  • The findings suggest that hearing impairment may have a more pronounced negative impact on cognitive function in men compared to women.
  • Further research is warranted to elucidate the underlying mechanisms driving these gender-specific associations and to inform targeted interventions.
