Association of Unilateral and Bilateral Speech-In-Noise Hearing Status With Dementia.

Key Points

• This research aims to explore the link between unilateral and bilateral hearing status and the risk of dementia along with brain volume differences.
• Compared dementia risk based on unilateral and bilateral hearing status.
• Conducted assessments of brain volume related to hearing capabilities.
• Analyzed implications for hearing conservation strategies.
• Identified significant disparities in dementia risk based on hearing status.
• Bilateral hearing correlates with larger brain volume than unilateral hearing.
• Proposed that hearing conservation strategies should consider hearing status laterality.
