A recent article from Hankyoreh highlights the growing concern of presbycusis or age-related hearing loss, which affects more than 40% of people aged 65 and older. The article points out that symptoms such as needing to increase the TV volume or frequently asking for repetitions might indicate more than mere aging—they could signal a serious health issue. Healthcare experts warn that ignoring these signs can lead to social isolation, depression, and an increased risk of dementia. As hearing loss progresses, it can impair cognitive function and result in severe complications in daily life.

Presbycusis occurs as the inner ear and auditory nerve age, leading to diminished auditory cell function. This condition typically manifests symmetrically in both ears and is characterized by difficulty hearing high frequencies, making it more challenging to comprehend spoken language even if it is audible. Long-term exposure to noise, genetic factors, and chronic conditions such as diabetes and high blood pressure can exacerbate the problem, possibly leading to an earlier onset of hearing loss for vulnerable individuals.

The piece underscores a crucial finding: moderate hearing loss approximately triples the risk of dementia, while severe loss can increase the risk up to fivefold. The decline in auditory input negatively impacts brain functions related to language processing, which may lead to communication difficulties and worsen social isolation. Due to the gradual nature of hearing loss, individuals may not be aware of their declining hearing capabilities, necessitating proactive observation and intervention from family members to ensure their well-being.
