Study Shows Noise-Induced Hearing Loss Can be Blocked with Drug Compound

Inner hair cells of the cochlea (green and blue) excite auditory nerve fibers (red) by releasing glutamate, a chemical signal that helps convert sound waves into electrical signals that travel to the brain. But too much glutamate can be harmful, leading to noise-induced hearing loss. Studying mice, researchers at Washington University School of Medicine in […]

Research Shows Opioid Use Could Cause Hearing Loss

Opioid use, particularly in high doses, can cause deafness, according to Rutgers researchers. The study, published in The Journal of Medical Toxicology, reviewed records from the New Jersey Poison Control Center, based at Rutgers New Jersey Medical School, from 1999 to 2018 to determine the association between opioid use and degrees of hearing loss. Researchers identified 41 people with opioid […]

Hearing Loss Linked to Dementia Pathway

Hearing impairment was linked to neuropathological hallmarks of dementia, an autopsy study suggested. In older adults who were cognitively normal, impaired hearing was associated with tau neurofibrillary degeneration, reported Willa Brenowitz, PhD, MPH, of the University of California San Francisco (UCSF), and co-authors. And in people with dementia, hearing loss was tied to microinfarcts but […]

Bone Disease Medication May Help Reverse Hearing Loss

Preliminary findings from Harvard Medical School researchers at Massachusetts Eye and Ear may pave the way for trials to test bone density medications for hearing loss. Hearing loss caused by damaged nerves, whether from sound exposure or aging, is irreversible. There are currently no medications approved by the Food and Drug Administration (FDA) to treat […]

Vitamin B12 Deficiency Could Contribute to Tinnitus

A vitamin B12 deficiency is more prevalent in people who reach 60 years old and above. Have you been hearing a ringing in your ear? It could be a sign you’re lacking the nutrient. Vitamin B12 is found in the foods you eat. Normally, the protein is absorbed in the gut to be used by […]

New Cause of Age-Related Hearing Loss Discovered

For the past 60 years, it has been thought that age-related hearing loss, known as presbycusis, is driven primarily by damage to the stria vascularis, the cellular “battery” that powers the hair cell’s mechanical-to-electrical signal conversion. A new study of human ear tissues upends that thinking and identifies a new cause of age-related hearing loss—opening […]

Ear Infections Discovered in Remains from 15,000 Years Ago

Researchers at Tel Aviv University have discovered evidence of ear infections in the skull remains of humans living in the Levant some 15,000 years ago. “Our research seeks to determine the impact of our environment on illnesses in different periods,” says lead author Dr. Hila May of the Department of Anatomy and Anthropology at TAU’s […]

Humans’ Ears Perk at Interesting Sounds Like Animals

Many animals, including dogs, cats and various species of monkeys, will move their ears to better focus their attention on a novel sound. That humans also have this capability was not known until now. A research team based in Saarland has demonstrated for the first time that we make minute, unconscious movements of our ears […]

What is Hidden Hearing Loss?

It can be frustrating for people who struggle to hear everyday sounds and conversations to undergo a hearing test and have it come back normal. They know something isn’t quite right with how they hear yet standard audiological testing doesn’t reveal that. This situation could indicate a problem known as hidden hearing loss.  Although it […]

Hearing Loss Linked to Gene Mutations

Mutations in the TGFBR1 gene, the underlying cause of some cases of vascular Ehlers-Danlos syndrome (vEDS), may lead to hearing loss by preventing the formation of key sensory cells in the inner ear during development, a study in mice has found. The research also provided key insights into the factors driving the formation of these sensory cells, which may […]
