Recent research shows that the link between hearing and brain health is much stronger than previously believed. Even mild hearing loss can increase the risk of developing Alzheimer’s disease and other forms of dementia, highlighting the importance of early detection and treatment.
How Hearing Loss Affects the Brain
According to a comprehensive study by Johns Hopkins University, the risk of dementia increases with the degree of hearing loss [1]:
-
Mild hearing loss doubles the risk of dementia.
-
Moderate hearing loss triples the risk.
-
Severe hearing loss increases the risk fivefold.
Researchers point to several mechanisms behind this connection: hearing difficulties can lead to social isolation and reduced cognitive stimulation, and the brain must work harder to interpret sounds, which may accelerate cognitive decline [1].
Hearing Aids Can Slow Cognitive Decline
There is, however, hope: a study from the National Institutes of Health (NIH) found that the use of hearing aids reduced cognitive decline by nearly 50% among older adults at high risk of dementia over a three-year period [2].
Another study from Johns Hopkins showed that individuals with moderate to severe hearing loss who used hearing aids had a 32% lower incidence of dementia compared to those who did not use hearing devices [3].
Hearing Loss as a Major Preventable Risk Factor
The Lancet Commission has identified hearing loss as one of the largest modifiable risk factors for dementia. Their 2020 report estimates that treating hearing impairment could prevent up to 9% of all dementia cases globally [4].
How to Protect Your Cognitive Health
-
Undergo regular hearing checks, especially after the age of 50.
-
Use hearing aids if recommended, to reduce cognitive strain and improve quality of life.
-
Stay socially active, even if hearing declines.
-
Protect your hearing by using hearing protection in noisy environments.
Early intervention can play a crucial role in preserving both your hearing and cognitive function – and thereby reduce the risk of Alzheimer’s disease.
Sensorem’s personal alarm has GPS positioning, medication reminders and automatic fall alarm
Sensorem’s personal alarm is an example of a technical aid specially developed for people with dementia. The personal alarm works outdoors and has built-in GPS positioning so that relatives can see the user’s position on a map in the Sensorem app. Relatives are automatically called by the personal alarm (two-way communication) if the user leaves a predetermined geographical area. The personal alarm also has medication reminders, which means that the watch emits a sound and tells the user that it is time to take their medication. The personal alarm can also alert automatically in the event of a fall with the built-in fall sensor.
