Preserving Good Hearing Linked to Safeguarding Cognitive Function

The Connection Between Hearing Impairment and Dementia

Numerous studies have highlighted the strong connection between hearing impairment and dementia. However, a recent report suggests that attending to your hearing health could be instrumental in guarding against cognitive decline. The Lancet, a reputable medical journal, published a report on July 30, 2020, indicating that hearing loss is a significant modifiable risk factor for dementia.

According to The Lancet study, “hearing loss might result in cognitive decline through reduced cognitive stimulation,” highlighting the importance of taking steps to address hearing loss. Taking proactive measures to manage hearing loss promptly could potentially decrease the risk of cognitive decline and dementia.

Adjustable Risk Factors

There are 12 modifiable lifestyle factors, including hearing loss, that collectively account for approximately 40% of dementia cases worldwide. The Lancet study proposes that mitigating these risk factors may lower the risk of developing dementia. These modifiable risk factors encompass:

• Limited education
• Hypertension
• Excessive alcohol consumption
• Obesity
• Smoking
• Depression
• Social isolation
• Physical inactivity
• Air pollution
• Diabetes
• Hearing loss

Modifying these risk factors has the potential to prevent or delay a significant portion of dementia cases, possibly up to 40%.

Numerous studies have highlighted the strong connection between hearing impairment and dementia.

Maintaining Mental Stimulation

Hearing, being one of our primary senses, enables us to engage with others and lead an active life. Research has established a correlation between untreated hearing loss and withdrawal from social interactions, social isolation, stress, depression, and diminished performance at work or in educational settings. Another study indicates that “hearing impairment is associated with a 30-40% rate of cognitive decline”. Addressing hearing loss and ensuring continued mental stimulation is a proactive way to guard against the risk of cognitive decline.

Sustaining open channels of communication by managing hearing loss may facilitate a vibrant and active lifestyle at all stages of life. This is particularly crucial in the mid to later stages of life when the risk of dementia tends to escalate.

Enhancing Long-term Well-being

Caring for your ears is of utmost importance. Safeguarding your ears from excessively loud noise can potentially prevent hearing loss. If you suspect hearing loss, it is advisable to have your hearing assessed promptly to facilitate effective management.
