The Incidence of Sensorineural Hearing Loss Diagnoses in People with and without Parkinson's Disease

Parkinson's disease (PD) and sensorineural hearing loss (SNHL) are both prevalent conditions among older adults. Although increasing number of studies have investigated SNHL as a risk factor for PD, it is not well known how diagnosed PD affects the likelihood of SNHL diagnosis. OBJECTIVES: To evaluate the temporal changes in the amount of SNHL diagnoses in relation to PD diagnosis.

Discussion

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

Audiologists should be alert to a potentially elevated rate of sensorineural hearing loss in patients with Parkinson's disease, warranting proactive hearing screening in this population — though causation is not established from this epidemiological design.

✦ Why It Matters ✦

Establishing an epidemiological link between Parkinson's disease and sensorineural hearing loss could drive routine hearing screening protocols for a large and growing patient population globally.

✦ Key Points ✦

01Epidemiological study compared sensorineural hearing loss (inner ear nerve damage) incidence in Parkinson's vs. non-Parkinson's populations.
02People with Parkinson's disease had a higher incidence of sensorineural hearing loss diagnoses.
03Shared neurodegeneration pathways may underlie both conditions.
04Published in Movement Disorders Clinical Practice, 2026.
05Observational design limits causal conclusions; confounding is possible.
