Vocal biomarkers of aging and Parkinson’s disease in a songbird

2026-07-29

Abstract excerpt

<h4>Purpose</h4> Similar vocal impairments occur in normative aging and Parkinson’s disease (PD), making differential diagnosis challenging in early stages. The brain’s role in age and PD-related vocal dysfunction is unclear. This motivated our use of the zebra finch songbird model. We applied human acoustic analysis to evaluate aging and parkinsonian-like birdsong for shared and distinct features. <h4>Method</h4...
