Blood tests are decentralizing dementia care

⚡ The Signal

A quiet revolution is happening in primary care. Recent clinical breakthroughs mean that Alzheimer's blood tests offer new promise to diagnose and predict the disease, shifting the diagnostic burden away from specialized neurology clinics directly to family doctors. With massive improvements in testing making diagnostics more accessible, patients can now get screened with a simple blood draw.

But this sudden democratization of high-tech testing has run headfirst into a massive administrative brick wall.

🚧 The Problem

Primary care providers are not neurologists. They are not trained to interpret complex longitudinal biomarker ratios, manage the anxious months patients spend waiting for a specialist appointment, or continuously monitor cognitive decline in the interim.

Once a patient's blood test shows elevated biomarkers, they face specialist wait times that often stretch from six months to a year. During this limbo, there is no standardized way to track their functional cognitive status. Primary care clinics are left manually compiling lab results, chasing down PDFs, and trying to patch together referral dossiers while patients decline in the dark.

🚀 The Solution

Meet Mnemos.

Mnemos is a diagnostic tracking portal and clinical dashboard designed specifically for decentralized, blood-based dementia screening in primary care.

Instead of letting high-risk patients slip through the cracks while waiting for a neurologist, Mnemos equips clinicians with an automated system to manage the entire early-stage window. It combines a clinician-facing dashboard that aggregates blood biomarker data over time with a patient-facing portal that runs weekly, gamified cognitive micro-tasks. The result is a unified, continuous clinical picture that automates the neurology referral process with a single click.

💰 The Business Case

Revenue Model

Mnemos generates predictable, high-margin revenue through three distinct streams:

• SaaS Subscription: A per-clinician monthly SaaS subscription tier for primary care practices.
• Remote Patient Monitoring (RPM): An enablement fee where the platform takes a cut of the billing under CPT codes 99453 and 99454 for continuous cognitive monitoring.
• Clinical Trial Pipeline Matching: A referral fee for matching de-identified, early-stage patients with clinical trials for emerging therapeutics based on their specific biomarker profiles.

Go-To-Market

To drive rapid adoption, Mnemos leverages a bottom-up, product-led growth strategy:

• Open-Source Testing Library: An open-source React cognitive testing library that digitizes standard Trail Making Tests, driving organic developer and tech-forward clinician adoption.
• Biomarker Reference Calculator: A free, web-based tool where clinicians input raw p-tau or amyloid ratios from labs like Quest or Labcorp to instantly generate a standardized PDF trendline.
• Programmatic SEO: Highly targeted programmatic landing pages addressing localized search queries like "p-tau217 clinical reference range primary care" to capture intent-driven clinical search traffic.

⚔️ The Moat

While competitors like Linus Health, Cognivue, BrainCheck, and Darmiyan focus on isolated computerized cognitive assessments or brain image analysis, Mnemos wins on workflow integration and dual-data accumulation.

By capturing both functional cognitive data (via weekly gamified tasks) and chemical biomarker data (via longitudinal blood tests) in a single clinical dashboard, Mnemos builds a proprietary longitudinal baseline. Once a primary care clinic integrates this dashboard into their standard EHR referral workflow—saving them hours of manual documentation during neurology handoffs—the switching cost becomes prohibitively high.

⏳ Why Now

The clinical reality of dementia care changed forever this year. As noted in the New York Times, new blood tests are offering unprecedented diagnostic accuracy outside of specialized imaging centers.

With advancements in therapeutic treatments and diagnostics aligning to make early intervention actually meaningful, the clinical infrastructure must evolve immediately. Primary care is the new frontline of Alzheimer's care, and they need the software layer to survive it.

🛠️ Builder's Corner

Building an MVP for a clinical dashboard like Mnemos requires balancing rapid front-end iteration with robust, secure data handling.

One elegant way to build this is a Next.js framework hosted on Vercel, using Tailwind CSS for rapid dashboard interface development. For the backend, a Supabase PostgreSQL database with row-level security and encryption is perfect for managing sensitive patient records.

The front-end gamified cognitive micro-tasks can be constructed using lightweight React state and HTML5 Canvas to keep interactive elements snappy and cross-platform. To render the trendlines of p-tau and amyloid biomarkers, reach for Chart.js to build clean, interactive data visualizations. Finally, generate the clinical transfer PDFs dynamically using a library like react-pdf/renderer, while securing the entire application with multi-factor authentication managed through Clerk. This stack ensures you hit the ground running with an enterprise-grade, secure, and highly visual product.
