The provided text outlines a mechanistic taxonomy designed to resolve the scientific inconsistency of treating PTSD as a single, uniform disorder. By moving beyond traditional symptom checklists, the author proposes a six-type model grounded in distinct biological patterns involving autonomic, metabolic, immune, and dissociative systems. These six phenotypes—Hyperadrenergic, Dissociative, Reward-Collapsed, Identity-Fragmented, Somatic-Sensitization, and Immunometabolic—explain why patients vary significantly in their physiological markers and recovery paths. This framework argues that treatment sequencing must be personalized, as interventions like exposure therapy may stabilize one type while destabilizing another. Ultimately, the text advocates for a transition from a descriptive diagnosis to a predictive science of adaptation that utilizes longitudinal data and objective biomarkers. This shift aims to reduce clinical trial noise and provide a reproducible architecture for understanding how different human systems reorganize following extreme trauma.
