Scientists find technology to reverse hearing loss
We may not understand the hardships of the people who suffer from hearing loss. But what is hearing loss?
What is hearing loss?
Hearing loss is caused by damage of the inner ear, auditory nerve or brain damage.
Hair cells die when they are exposed to loud noises. It leads to hearing loss in patients. It can lead the patients to isolation, frustration and a constant ring in the ears that is known as tinnitus. Hearing loss can lead to dementia.
Reversing the hearing loss
The company Frequency Therapeutics is trying to reverse hearing loss. It’s not hearing aids or an implant, but it is a new regenerative therapy.
What is the new technology?
Scientists from MIT (Massachusetts Institute of Technology) have found the technology which will help in reversing hearing loss. They have used small molecules to progenitor cells (descendants of stem cells) to create tiny hair cells that allow people to hear.
Frequency Therapeutics has designed a drug candidate which is injected into the ear to regenerate the hair cells with the cochlea. The cochlea is a tube in the inner part of the ear that contains nerves that carry information to the brain.
Trials by the company
The company conducted trials and took speech tests on the patients. A speech test is the ability to understand speech and recognise words. Moreover, it is the most important need that patients with hearing loss.
In the study conducted by the company, the patients were given the injection and there were improvements in their speech perception.
More than 200 patients have received their injection doses to date. The researchers have found improvements in the patients.
Currently, the company is looking forward to the 124-person trial and the results for these will be available in the next year.
