Even with only minor hearing loss, the parts of your brain that handle auditory processing can switch to visual processing instead, per a 2014 study. When fewer sounds make their way to the brain, the brain reacts by shifting how it operates. Your ears deliver sound as electrical impulses via the auditory nerve, but it’s within your brain that these electrical impulses are translated into what we recognize as sound. Remember: Hearing is a brain activity (sometimes referred to as "brain hearing"). Brain atrophy from untreated hearing loss Pulido, AuD, of HearCare Audiology Center in Sarasota, Fla. “Auditory deprivation is when the brain has difficulty understanding and processing information due to the lack of stimulation,” said audiologist Jenilee P. Those parts also tend to shrink or atrophy. It can affect anyone with hearing loss, not just severe cases. If left untreated, the parts of the brain normally responsible for hearing get "reassigned" to other tasks. Over time, your brain loses the ability to process sound. What is auditory deprivation?Īuditory deprivation occurs when your brain is deprived of sound, such as from untreated hearing loss. Yes, you read that right: Brain shrinkage can occur if you don't treat your hearing loss. That’s a mistake that’s best avoided, since failing to treat hearing impairment can result in auditory deprivation-and over time, the parts of your brain responsible for hearing can shrink or atrophy from lack of use. Even after diagnosis, people wait an average of 10 years to actually get the hearing aids that’ll help them hear better. The signs may be subtle-you keep having to turn the TV up, or you struggle to hear your grandkids. 2016 56:597.Very often, people aren’t aware of hearing loss, because it occurs slowly over a matter of years.

Some people have good word recognition, while others get more general sound cues. But it helps most people distinguish sounds such as telephone rings and car horns. ResultsĪn auditory brainstem implant doesn't restore normal hearing. You'll generally see an audiologist every two to four months the first year and annually after the first year. After the procedureĪfter surgery, you'll need many sessions with an audiologist to adjust the sound processor and learn how to use and interpret the signals. If you have neurofibromatosis type 2, the surgery is often performed at the same time tumors are removed from the hearing (auditory) nerves. ![]() Electrodes connected directly to the brainstem that, when stimulated, alert you to sound. ![]() A decoding chip placed under the skin to transmit information picked up by the microphone.A microphone and sound processor positioned behind the ear to pick up sounds.Auditory brainstem implants have three main parts: a microphone and sound processor positioned behind the ear a decoding chip placed under the skin and electrodes connected directly to the brainstem.Īuditory brainstem implants have three main parts:
