What this research studies

This project aims to find why hearing steadily worsens with age by studying changes in ear neurons, myelin insulation, and neural circuitry. The team uses multiple linked projects and shared lab cores, combining genetics, imaging, analytical chemistry, and animal models to map cellular and structural changes across the auditory pathway. By comparing results across scales and techniques, they plan to pinpoint targets that could be reversed or protected. The work is intended to lead toward therapies or tests that could help people with presbycusis.

Who could benefit from this research

Good fit: Older adults with age-related (sensorineural) hearing loss would be the most likely candidates for related clinical trials or participation.

Not a fit: People with hearing loss from sudden injury, congenital causes, or conductive problems like ear canal blockage may not benefit from these approaches.

Why it matters

Potential benefit: If successful, this work could lead to new treatments or tests that prevent or restore hearing loss in older adults.

How similar studies have performed: Some preclinical and early clinical work targeting nerve health and myelination shows promise, but full reversal of age-related hearing loss in humans remains largely unproven.
