FDA-Aligned Endpoint Framework for Precision Acupuncture Planning
Encephalopathy Connectomic Collapse Atlas (ECCA-PRION)
I. PURPOSE
The SCF Prion Encephalopathy Biomarker Panel is designed to:
- Establish prion encephalopathy diagnostic support
- Quantify ultra-rapid connectomic collapse
- Differentiate prion disease from other dementias
- Measure neurodegenerative acceleration
- Predict neurologic decline and survival
- Stratify supportive neuromodulation planning
- Support FDA-aligned translational endpoint development
- Forecast terminal network failure trajectories
II. ETIOPATHOGENIC CORE
Prion encephalopathies are characterized by:
- Misfolded prion protein propagation
- Self-amplifying protein templating
- Synaptic destruction
- Massive neuronal loss
- Astrocytic activation
- Spongiform degeneration
- Rapid connectomic disintegration
- Brainstem-autonomic failure
- Global cortical collapse
