A Bit About Hearing Loss and the Brain with Kelly Tremblay, PhD

In this episode of Brain Bytes, host Kelly Tremblay, PhD, neuroscientist and hearing and brain health expert, explores the powerful—and often overlooked—connection between hearing and the brain.  In recognition of World Hearing Day on March 3, Dr. Kelly sheds light on why hearing health is critical to overall well-being, especially for older adults. Hearing loss is one of the leading causes of years lived with disability worldwide, affecting one in three adults over 65. But, as Dr. Kelly explains, it's not simply an inevitable part of aging—lifestyle factors, environmental exposure, and even certain medical treatments can play a significant role. This episode illuminates why hearing loss is closely linked to brain health and cognitive decline, how untreated hearing loss can contribute to social isolation and increased dementia risk, and how to recognize early signs of hearing loss. Dr. Kelly examines how hearing is not just about the ears, it's a brain function, and why early detection and intervention can significantly improve quality of life, communication, and cognitive health.
