Hearing loss can interfere with cognitive abilities because a lot of brain effort goes into understanding speech, according to lead researcher Dr. Several scientific studies have found that hearing aids keep the brain fit and can protect against cognitive decline. For example, people who use hearing aids for age-related hearing problems (age-related hearing loss) maintain better brain function over time than people who don't use them. Now, think about hearing aids and cochlear implants.
These devices modify the physical characteristics of sound. Hearing aids introduce noise, compress signals and alter the frequency content of the signal. Therefore, when evoked potentials are recorded using sound emitted through a hearing aid, the effects of hearing aid processing on the physical characteristics of sound are likely to affect the evoked neural response pattern. This interaction may seem obvious, but you'd be surprised to find that these issues are rarely considered when you read posts.
Experts agree that it is necessary to exercise the brain to maintain healthy brain function. This means keeping your brain alert by keeping up with your hobbies, doing daily crossword puzzles in the LA Times and playing mind games. If you have hearing loss, simply wearing hearing aids can work wonders for how your brain works.

There is a period of breakthrough as you, your central auditory system, and your brain adjust to life with hearing aids. That's why most doctors and hearing centers include a trial period, so you can be sure that the type you've chosen, whether it's a miniature behind-the-ear model or one that fits your ear, is right for you. We usually think of hearing in relation to the ear, but sound travels along many nerve fibers and through many nuclei before reaching the auditory cortex. For example, it has been difficult to demonstrate the benefits of digital noise reduction algorithms, as implemented in hearing aids, to improve speech recognition in noisy situations.
Putting on your hearing aids may require some adjustments, especially if it's been a while since your hearing was at full. For example, individual evoked response patterns may reflect differences between hearing aid processors rather than differences in brain activity. Researchers used a variety of behavioral and cognitive tests designed to assess participants' hearing, as well as their working memory, attention, and processing speed. At the end of the six months, participants showed improved memory, improved neural speech processing, and greater ease of hearing as a result of using the hearing aid.
The central auditory system of a person diagnosed with conductive or sensorineural hearing loss has experienced deprivation-related plasticity. And clinically things can get even more confusing when the electrophysiology expert isn't the hearing aid expert, and vice versa. The research team is working on developing better procedures for attaching hearing aids to people for the first time. In all cases, changes in the hearing aid prescription can be presumed to contribute to changes in evoked neural responses.
Researchers at UMD say the results of their study provide hope that the use of hearing aids could at least partially restore deficits in cognitive function and auditory function of the brain in older adults. As Tremblay and Miller describe in this special issue, this complex ear-brain neural network system begins with the sound coming out of the hearing aid. In addition, your hearing will change over time, so be sure to keep up with your hearing care appointments. Scientific studies have found that sound processing in the brain is not the only thing affected by untreated hearing loss.
With headphones on, sounds from your surroundings (such as the buzzing sound of the dishwasher or refrigerator) may seem loud, as can the sound of your own voice, says Pulido. . .
