Can tear biomarkers be used for Alzheimer's disease screening and diagnosis

Puntos clave

• Tear biomarkers show significant promise in the screening and diagnosis of Alzheimer's disease.
• A key finding is the correlation between phosphorylated tau levels and disease severity.
• Assessment using biomarker analysis revealed critical differences in tear fluid composition.
• The results indicate that tear biomarker analysis could provide a non-invasive diagnostic tool.
