Does hearing loss bring about dementia?

Hint: It’s not a simple response.

There’s some disagreement about if hearing loss causes cognitive dysfunction in the kind of dementia. Dementia is a broad group of brain ailments. The most frequent type of dementia is Alzheimer’s disease. Dementia affects a individual’s long term capacity to think and recall. Researchers have conducted several studies planning to ascertain if there’s a connection between hearing loss and dementia. However, it’s extremely tricky to ascertain whether hearing loss triggers cognitive impairment, or if hearing loss is merely correlated with that.

Need a refresher about the distinction between correlation and causation?

Correlation signifies two items are only associated with one another or have some connection to one another. Nano hearing aid company that one thing causes another. Here is a good example to help explain the difference:

On days where you will find is a spike in the sale of sunscreen, there’s also a spike in incidents of drowning. Does this imply purchasing sunscreen causes individuals to drown?? Probably not. Most probably, the frequent denominator is sexy summer days. On warm summer days, more people head out to purchase sunscreen and more individuals choose to go swimming. And the more people who float, the greater the probability that somebody will drown. Only because more people purchase sunscreen around the exact times that more folks drown does not mean purchasing sunscreen causes drowning!

Alright so now that we have explained the distinction between correlation and causation, we could get back to discussing what you came here to see: the connection between hearing loss and dementia.

Basically, scientists have managed to prove there is a correlative relationship between hearing loss and cognitive impairment. However they have not been able to verify that hearing loss causes cognitive impairment.

Below are a couple of studies which explain the connection between hearing loss and cognitive impairment:

A 2014 research on the association between dementia and hearing loss revealed that people over 65 with hearing loss have an increased rate of developing dementia compared to their non-hearing diminished counterparts. The consequence of the analysis is that hearing loss and dementia are correlated. Hearing loss may be a mark for identifying cognitive dysfunction such as dementia in people 65 decades old and older.
A 2015 research on the connection between hearing loss and risk of Alzheimer’s Disease revealed that after controlling for various factors, and analyzing 488 individuals in Taiwan, hearing loss was correlated with a greater risk of Alzheimer’s disease in elderly individuals. Alzheimer’s disease is a kind of dementia.
So why can hearing loss seem to be associated with cognitive impairment?
There are lots of explanations for why hearing ability and thinking abilities seem to be connected. To begin with, hearing loss may result in social isolation that’s associated with cognitive impairment. Secondly, because hearing loss induces the mind to work overtime processing the signals in the ears, so it’s likely that the mind gets less power to expend on other cognitive capabilities .

And here is where there may be some evidence to causation: 2015 results from an ongoing study known as the Baltimore Longitudinal Study of aging that was started all of the way back in 1958 revealed that hearing loss has been connected to accelerated brain tissue reduction. After assessing MRIs of individuals with with diminished hearing, scientists discovered that people who have hearing loss lost greater than an extra cubic centimeter of brain tissue annually compared with people who did not have hearing loss.

In particular, people who have hearing loss had more shrinkage in brain structures in charge of processing sound and hearing. Scientists believe this shrinkage is since individuals with hearing loss have diminished stimulation in areas of the brain that control speech and hearing. Moreover, this may explain the connection between hearing loss and dementia because dementia entails damage to the mind.
