Cognitive Decline and Hearing Loss: What Audiologists Need to Know
Since communication difficulties are one of the earliest signs of dementia, audiologists are uniquely positioned to make timely referrals that can improve long-term outcomes, allowing for earlier diagnosis and management of cognitive decline.
In this article, originally published in Audiology Today, Dr. Grace Gore Sturdivant discusses the critical role hearing health plays in cognitive wellbeing and why early intervention matters.
Untreated hearing loss is now recognized as the single largest modifiable risk factor for dementia — a finding that has shifted how audiologists, neurologists, and primary care physicians approach routine hearing care. One well-supported explanation is that years of effortful listening gradually deplete the cognitive resources the brain would otherwise use for memory and executive function. Communication difficulties often emerge before other signs of cognitive decline become apparent, which means the audiology appointment is frequently the earliest opportunity to identify a patient who may benefit from referral. This piece, written for Audiology Today, outlines the evidence and makes the case for treating every hearing evaluation as a window into long-term brain health — not just a measurement of what someone can hear today.
