Potential oral biomarkers for AD diagnosis

Biomarkers
Oral microbiome (e.g., presence in AD brain)
Volatile organic compounds (e.g., unique profiles among neurodegenerative diseases)
Salivary proteomics (e.g., Aβ peptides, tau, and lactoferrin, salivary acetylcholinesterase activity linked to AD)
Salivary lipidomics (a new frontier for AD)
