Why It Matters
The research reviewed nine previous meta-analyses on the relationship between hearing and brain health. The study was conducted by the Neurology team at Chongqing Three Gorges Medical College.
Adults with hearing loss are at increased risk of developing cognitive decline, dementia and Alzheimer's, according to a large scientific analysis published this week that reviewed available evidence on the relationship between hearing problems and brain health.
The research, published in the journal Frontiers in Aging Neuroscience, evaluated nine previous meta-analyses and concluded that hearing loss is associated with a 34% increased risk of cognitive decline and a 43% increased risk of dementia. Additionally, people with hearing difficulties are 66% more likely to develop Alzheimer's disease.
The authors, from the Neurology team at Chongqing Three Gorges Medical College (China), pointed out that the relationship is especially intense in elderly people and recalled that hearing loss "has become one of the most studied potentially modifiable factors in the prevention of cognitive decline."
Although the work does not demonstrate a direct causal relationship, the results reinforce the hypothesis that maintaining good hearing health could help protect cognitive abilities during aging.
Open Questions
- Is there a direct causal relationship between hearing loss and dementia?
- Can the use of hearing aids effectively reduce these risks?
