Title: Bioelectrical and Biological Pattern Failure Before Cell Death: A Recursive Diagnostic Terrain Model for Chronic Fatigue, Autonomic, and Immune Collapse in POTS, MCAS, ME/CFS, Autism, ADHD and Chronic Illness Patient and Provider Handouts with Clinical Walkthrough: https://grahammedical.substack.com/p/bioelectric-and-redox-terrain-failure Description:This work presents the second layer in a recursive diagnostic terrain framework that redefines redox imbalance, methylation collapse, and purinergic amplification as early, actionable checkpoints in complex chronic illness. It builds upon the foundational terrain architecture introduced in: Graham, J. (2025). Intracellular Iron Deficiency and Mitochondrial Iron Miscompartmentalization as a Convergent Mechanism... https://doi.org/10.5281/zenodo.15693226 Here, ferroptotic bias is recast not as a terminal event but as a nutrient- and redox-sensitive terrain checkpoint that precedes immune, vascular, and autonomic collapse. This system stratifies collapse trajectories across PEM, ME/CFS, POTS, MCAS, Autism, ADHD and related disorders. This links biochemical and bioelectrical signals (e.g. P2X7/NLRP3 activation, glutathione depletion, D-dimer/VEGF elevation) to terrain-based diagnostics that are clinically actionable. The model integrates evolutionary physiology, redox and mitochondrial biology, and methylation dynamics to detect pre-symptomatic failure and define therapeutic inflection points. It incorporates Michael Levin’s bioelectrical patterning model to explain morphogenetic disarray and immune bifurcation as pattern memory loss.

A Scope and Clinical Use Declaration is embedded to define ethical and medico-legal parameters. While openly accessible, any clinical, translational, or derivative use requires full scope fidelity. Fragmented or decontextualized use risks iatrogenic harm, diagnostic misclassification, and therapeutic misdirection. This model is clinically actionable, recursive, non-theoretical, and diagnostically inseparable. It is a harm reduction tool. Author Context:Developed by a credentialed clinician with a background in zoology, former bedside nurse, and disabled patient. This work unites layered clinical insight, evolutionary modeling, and lived experience into a single recursive diagnostic lens. It is unapologetically patient-first and epistemically non-fragmentable. Ethics Statement: “Nothing about us, without us.” Those who do not recognize patient agency have no agency in this discussion.
