Recent massive AI studies have shown how hearing impairment can cause Dementia or lead to it.
Using AI to review medical problems of many patients:
AI Overview: Yes, dual sensory impairment (DSI) of hearing and vision is strong!

Yes, dual sensory impairment (DSI) of hearing and vision is strongly associated with an increased risk of dementia in older adults. In fact, people with DSI are nearly twice as likely to develop dementia as those without impairments. For example, a 2022 cohort study of over 500,000 people in the UK found that participants with DSI had an 82% higher risk of dementia, compared to 50% for those with vision impairment alone and 42% for those with hearing impairment alone.

Hearing plus vision loss increases the odds of dementia
Jul 20, 2020 — People with both hearing and visual loss were nearly twice as likely to develop dementia as those without such impairments. However, according to the results, the increased risk of dementia for an individual with DSI is only somewhat related to the severity of hearing and visual impairment. While those classified as having a high level of DSI are at the greatest risk of developing dementia, those with lower DSI levels also have a significantly higher risk of dementia.

May 5, 2022 — Question Is dual sensory impairment associated with risk of dementia, including Alzheimer disease and vascular dementia, among older adults? Findings In this cohort study that included 2927 adults aged 65 years and older, dual sensory impairment was associated with a 160% increased risk for all-cause dementia and a 267% increased risk for Alzheimer disease. Meaning These findings suggest that assessment of both hearing and vision may help to identify older adults who are at high risk of developing dementia.

Hearing and vision loss equals ‘substantial’ risk for dementia ...
Jul 11, 2022 — Similarly, a June 2022 cohort study in Frontiers in Aging Neuroscience, which looked at more than half a million people in the UK also found that participants with vision impairment had a 50 percent higher risk for developing dementia, while people with a hearing impairment had a 42 percent higher risk. Highest still was the risk for developing dementia in people with dual sensory impairment: 82 percent.
The increased risk of dementia for people with DSI is somewhat related to the severity of their impairments, but those with lower levels of DSI also have a significantly higher risk. Assessing both hearing and vision may help identify older adults who are at high risk of developing dementia.
Hearing loss can also be an early symptom of dementia. Central hearing loss, which is when the brain has trouble processing sounds, may be a very early symptom of Alzheimer’s disease. To: Reduce the risk of dementia: you can: Get your hearing tested, Protect your hearing from a young age, and Use hearing aids.
That’s strange. I had a great aunt who died at age 104 and was both deaf and blind! She was clear as a bell until last two yrs.
