Summary
This study explores the link between listening effort and cognitive function in adults, including those with mild cognitive impairment (MCI). Findings may inform future research on hearing loss and cognitive decline.
Area of Science:
- Neuroscience
- Audiology
- Gerontology
Background:
- Hearing loss is a modifiable risk factor for cognitive impairment.
- The role of listening effort in cognitive decline, especially in mild cognitive impairment (MCI), is under-researched.
Purpose of the Study:
- To investigate the association between cognitive functioning and listening effort in adults.
- To explore objective and behavioral measures of listening effort in relation to cognitive status.
Main Methods:
- Recruitment of 15-25 cognitively healthy participants and 15-25 MCI patients (age 40-85).
- Administration of the Sentence-Final Word Identification and Recall (SWIR) test with pupil dilation monitoring.
- Cognitive function evaluation using a neuropsychological test battery.
Main Results:
- This is an exploratory, proof-of-concept study.
- Data will guide the design and validity of larger-scale trials.
Conclusions:
- Further research is needed to understand the relationship between listening effort and cognitive decline.
- This study lays the groundwork for investigating interventions targeting listening effort in cognitive health.
