Untreated hearing loss is linked to accelerated cognitive decline, depression and social withdrawal. Most people wait several years before seeking help.
Difficulty hearing in noisy environments is often the earliest sign, appearing long before difficulty in quiet one-to-one conversation.
Conductive hearing loss arises from a problem in the ear canal or middle ear — wax impaction, fluid behind the eardrum, a perforation, or fixation of the tiny middle ear bones. Much of this is fully correctable with wax removal, medication or surgery.
Sensorineural hearing loss arises from damage to the inner ear or hearing nerve, most often from ageing or noise exposure. It is generally permanent, but it is very effectively managed with hearing aids, and with cochlear implants in severe cases.
Untreated hearing loss is now recognised as one of the largest modifiable risk factors for dementia. The mechanisms are thought to include the extra cognitive effort spent decoding speech, reduced stimulation of the auditory brain, and the social isolation that follows when conversation becomes exhausting.
Treating hearing loss is therefore not merely about convenience. It preserves social connection and appears to protect cognitive function — which is a much stronger reason to act early than most people are given.
Modern digital hearing aids are small, adjustable and considerably better than the devices most people picture. Adaptation takes several weeks — the brain has to relearn sounds it has not heard for years, and early on everything can seem uncomfortably loud. Wear them consistently through this period rather than abandoning them.
Have them fitted and tuned by an audiologist based on your own audiogram. Devices bought off the shelf that simply amplify everything are usually unsatisfactory and are a common reason people conclude hearing aids do not work.
Sudden sensorineural hearing loss — a rapid loss of hearing in one ear over hours to days — is a medical emergency. Steroid treatment started within the first two weeks, and ideally within the first few days, substantially improves the chance of recovery.
Do not wait to see whether it improves. Many people assume it is wax or a blocked ear and lose the treatment window.
