A Catalyst for Cognitive Decline

July is Healthy Vision Month—and an opportunity for ENTs to explore the intersection of vision and hearing in aging adults. Dual Sensory Loss (DSL)—the combined reduction in vision and hearing—is increasingly recognized as a driver of cognitive, functional, and emotional decline.

Emerging research suggests that DSL more than doubles the risk of dementia, increases the likelihood of falls, and dramatically reduces a patient’s ability to function independently. Yet DSL often goes unrecognized or is misattributed to aging, depression, or mild cognitive impairment.

Research Summaries: Clinical Evidence on Hearing, Vision & Brain Health

DSL and Dementia Risk

Kuo et al., 2021 – JAMA Network Open

A U.S. longitudinal cohort found that older adults with dual sensory impairment had a 50% higher risk of developing dementia over 7 years compared to those without sensory loss (adjusted HR 1.50, 95% CI 1.12–2.02)

Mental Health & Functional Decline

Doherty et al., 2014 – Frontiers in Public Health
A multi-country survey showed DSL is significantly associated with higher depression scores and difficulties in activities of daily living (ADLs) and instrumental ADLs

Increased Mortality Risk

Gopinath et al., 2013 – PLOS ONE (Blue Mountains Eye Study)
Older adults with DSL had a 62% increased 10-year all-cause mortality risk compared to unimpaired peers (HR 1.62, 95% CI 1.16–2.26)

Clinical Action Steps for ENTs

Screen for both hearing and vision in patients over 65—especially those reporting memory, balance, or communication difficulties. A simple intake question can prompt meaningful follow-up.
Refer for diagnostic audiologic testing promptly when hearing loss is suspected. Avoid delaying testing until the patient is “ready” for hearing aids—diagnosis is medically necessary on its own.
Coordinate with the PCP or ophthalmologist if dual sensory loss is suspected. Cross-specialty collaboration improves functional outcomes in older adults.
Integrate diagnostic audiology into routine patient flow using team-based protocols. Whether remote or onsite, increased access reduces delays in treatment.
Document sensory status in patient records—especially before making decisions about surgical candidacy, fall risk, or cognitive decline workup.

Patients over 65 frequently present with mild or moderate deficits in both vision and hearing. When these losses occur together, they amplify cognitive load, increase the risk of falls and depression, and contribute to faster functional decline—impacting independence and long-term quality of life.

ENTs have a unique opportunity to act. A comprehensive intake process that screens for both auditory and visual impairments can flag high-risk patients early, initiating timely interventions.

Case Example

Mrs. J, 72, experienced falls and confusion. ENT referral identified a moderate bilateral hearing loss, and optometry confirmed macular degeneration. After hearing aid fitting and low-vision support, her cognition stabilized, and her mood improved within three months.

Connon’s Corner: Increasing Diagnostic Capacity

Dual sensory loss is a critical clinical indicator—and yet ENT practices often lack the capacity to evaluate hearing loss quickly enough to intervene.

MaestroAuD™ was built to solve this. By embedding remote diagnostic audiologists into ENT practices, we ensure that every patient flagged by a physician can be seen within days—not weeks or months.

That speed matters. It enables a full diagnostic workup before the next follow-up visit and prevents patients from falling through the cracks.

MaestroAuD™ also frees up onsite audiologists to conduct hearing aid evaluations and fittings—getting treatment started faster. Amplification is not just a matter of comfort—it’s a pathway to improved cognition, function, and emotional health.

Every MaestroAuD™ provider is a Certified Dementia Practitioner (CDP®) trained in recognizing and responding to cognitive decline. DSL patients need that level of insight and urgency. With MaestroAuD™, ENT clinics deliver both.

Dual Sensory Loss by the Numbers

Adults with both hearing and vision loss are 8 times more likely to experience functional decline compared to those with no impairment. Maharani A, et al. JAMA Otolaryngol Head Neck Surg. 2020;146(6):553–560.
Dual sensory loss increases risk of depression by over 2.5 times and is strongly associated with reduced cognitive function. Shukla A, et al. JAMA. 2020;324(12):1175–1177.

The Urgency of Early Identification and Intervention

With DSL on the rise and audiology capacity strained, ENTs are in a critical position to reshape patient access. Early intervention is not optional—it’s essential. Models like MaestroAuD™ help ENT practices deliver care that supports hearing, cognition, and independence.
