Hearing loss may be a sign of dementia, according to new research.
But a hearing aid could help prevent cognitive decline and dementia by improving verbal communication and keeping the brain healthy, say experts.
The study found a small association between age-related hearing loss (ARHL) and increased risk for cognitive decline.
This includes executive function – which is the equivalent of a CEO of the brain – and episodic memory – autobiographical events such as times, places. Hearing loss was also linked to slower processing speed, cognitive impairment and dementia.
It is estimated two-thirds of the over 65s suffer hearing loss and previous studies have shown ARHL precedes the onset of dementia by five to 10 years.
Experts have suggested the lack of mental stimulation experienced by those who are hard of hearing may play a role in declined cognitive function.
