AI-powered, reagent-free blood diagnostic that captures full biochemical "fingerprints" via MX Raman optical spectroscopy and AI to detect and differentiate multiple dementias (Alzheimer’s, Lewy body, vascular, frontotemporal) in under 5 minutes. Designed for clinicians and diagnostic labs as a scalable, multi‑indication platform backed by a proprietary dementia spectral database and CLIA LDT pathway for early clinical deployment.
