I am involved , as a study subject, in a very long term study investigating hearing loss and dementia.
It is very real that if you don't use it you lose it. By not wearing a hearing aid all those brain connections to do with sound deteriorate , you become socially more isolated .
Ive seen this in my own family where family members got hearing aids and would not wear them. I am convinced their dementia got worse,quicker , because for years you would have nonsensical conversations because they couldn't hear what you were saying and so the conversation was entirely based on what they thought you said or was just a stream of consciousness with no backwards and forwards.
In many ways as a younger person you are lucky because
a you will be able to adapt easier to hearing aids
b will be able to partner better with an audiologist to get everything adjusted to your requirements
c you will be able to cope with the small buttons, changing batteries etc
d you will be able to fully use the technology eg blue tooth
e you will be able to maintain the hearing aids well. This is really important as hearing aids don't work when tubes are blocked by wax and you are much more likely to get ear infections if they never dry out.

to put them in over night will save you a lot of trouble. We've also used a small jewellery ultrasonic cleaner , not for the aid itself , but for the moulds , tubes etc .
We have a genetic type problem in our family and the youngest discovered at 17 that she needed a hearing aid . The difference it made was terrific , everyone thought they were shy and a bit antisocial but basically it was they couldn't hear in a crowd .
For those whose hearing aids are in a drawer , get them out or get new and wear them for both your physical and mental health .
