New Drug Regrows Auditory Hair Cells, Offering A Possible Cure For Deafness

By Hedrick Lepsch


If you attended too many rock shows in your youth, or if you grew up next door to a raised subway platform, then you'll be happy to hear about new research that could amount to a cure for deafness. British scientists are currently researching a drug which has been shown to reverse deafness in mice. The experimental drug, codenamed LY411575, allows for the regeneration of the sensory hair cells that are crucial to hearing, and scientists are hopeful it could someday soon be used to improve hearing in humans as well.

This is the first research to come out to show that auditory hair cells can be regrown. "It is possible to regenerate hair cells, and that's something that had not been possible before," said Albert Edge of Harvard Medical School, who led the study.

Some people who have experienced hearing loss are good candidates for cochlear implants. Unlike hearing aids, they stimulate your auditory nerves and bypass the damaged parts of your ears. Cochlear implants are not right for every situation, and are not the best option for those for whom hearing aids work well. To get a cochlear implant, you must meet with an audiologist to ensure you are a good candidate.

There are also other tools such as visual alarms that can be used instead of auditory warnings. These can be used as part of your alarm clock, or even your fire alarm and other important warnings that hearing people often take for granted. Even without hearing aids, there are plenty of things you can do to maximize your understanding. Some of these options are as simple as letting the person you are speaking with know of your difficulty.

Scientists tested the drug on a group of deaf mice over a period of 3 months. Scientists applied the drug inside the mice's inner ears, and by the end of the trial, the mice regained 20% of their hearing. Scientists caution that the drug is not yet ready for use on humans. There may be possible side effects that we don't know of yet, and other treatments-such as cochlear implants-are still more economically practical.

Megan and Jack are fine as well. Perhaps they've listened to a little too much loud music in their youth, but they still manage to hear each other whispering in close proximity. But as we skip a generation up to Mom, Dad and Aunt Sally, we start to see the hearing degradation. Dad and/or Aunt Sally might not even realize that their hearing has declined over the years. It's a subtle thing that can be blamed on other peoples' mumbling or the fickleness of volume controls on phones and TVs. And then we have Grandma. It's clear that she struggles with hearing loss, but she hasn't bothered to get much help. Offended by the idea that she needs hearing aids (that's for old people, missy!), she has let her hearing deteriorate unimpeded.
