BATScore: The Longitudinal Metric of Clearance Efficiency

BATScore is a longitudinal index developed by BATWatch Research Group (TeamBrain, Inc.) to quantify brain clearance efficiency over time. Derived primarily from BAT Levels, it integrates contextual adjustments from systemic inflammatory markers (e.g., hs-CRP, IL-6) and validated metabolic indicators (e.g., fasting glucose, insulin sensitivity) that reflect transient clearance pressure. Observational data from the BATWatch Registry (over 3,000 participants, 10,000+ data points) demonstrate that BATScore trajectories are stable within individuals and sensitive to clearance rhythm disruptions, making it a promising candidate for population-scale preventive neuroscience. This publication presents the conceptual framework, validation approach, and interpretive model for BATScore, while maintaining confidentiality of quantitative weighting and computational methods under the BAT Framework.
