Author: David K Millar, NeuroSynergetics | 2025 Neurodevelopmental disorders (NDDs) such as autism, ADHD, and OCD involve a convergence of oxidative stress, immune dysfunction, mitochondrial failure, and epigenetic suppression. The Iron Trap Hypothesis proposes a unifying model: that suppression of heme oxygenase-1 (HO-1) leads to iron becoming trapped in uncleaved heme—catalyzing a destructive redox loop driven by ferroptosis. This trapped iron state disrupts neurotransmitter synthesis, impairs myelination, alters synaptic pruning, and contributes to chronic neuroinflammation. Environmental triggers—such as glyphosate, fluoride, cadmium, and seed oils—suppress the Nrf2–HO-1–ceruloplasmin pathway, especially during critical windows of brain development. The hypothesis predicts a specific biomarker profile: elevated ferritin, low ceruloplasmin, suppressed HO-1, depleted glutathione, and epigenetic silencing of stress-response genes (e.g., HMOX1, BDNF, MECP2). While each marker has been observed individually, this is the first framework to integrate them into a coherent explanation for both dysfunction and adaptive brilliance in neurodiverse individuals. A multi-modal protocol targeting iron regulation, redox balance, and neuroplasticity is under evaluation. Importantly, the model directly maps blood-based biomarker patterns to behavioral outcomes, allowing for targeted, individualized intervention. Finally, this hypothesis introduces an evolutionary perspective—reframing neurodivergent traits not as pathology, but as context-dependent adaptations to modern environmental collapse. It offers a paradigm shift: from symptom management to root-cause remediation.
