The relationship between burnout and depression is one of the most contested questions in occupational health psychology. The empirical literature documents substantial overlap (exhaustion–depression correlation r ≈ 0.80; Bianchi et al., 2021) while also identifying structural neurobiological differences (burnout: prefrontal/striatal circuits; depression: hippocampal-amygdalar circuits). The debate has not been resolved because both sides operate at the symptom layer: they compare observable clinical features without a structural theory that specifies why burnout and depression are similar in some respects and different in others. This paper applies La Profilée (LP), a structural theory of persistence under real transformation, to burnout and depression as failure modes of personal identity persistence. LP specifies a universal persistence condition IR = R / (F · I) ≤ 1. When IR > 1 is sustained, structural identity erosion occurs. The person — as a system maintaining identity under continuous transformation — is subject to this condition as are cells, organisations, and ecosystems. The central structural finding is: Burnout and depression are not the same condition at different severity levels. They are structurally distinct failure modes that share the same terminal structural condition (IR > 1) but differ in the variable configuration that generates it. Burnout — most coherently modelled as Type 1 collapse (R-explosion dominant): External demands (R) escalate faster than integration capacity (I). The person is overwhelmed — not because identity is absent, but because the transformation pressure exceeds what identity-preserving integration can absorb. MBI exhaustion = I ↓; cynicism = F ↓ (Frame erosion); reduced efficacy = IK → 0. Depression (in the occupationally-related, anhedonic-rigide configuration addressed here) — most coherently modelled as Type 2/3 collapse (I-collapse and M-stagnation dominant): Integration capacity collapses — not from excess R, but from structural I-depletion or Frame-driven suppression of M (anhedonia = M → 0). The person is imprisoned in their own identity structure, unable to generate or absorb transformation. CL is extreme. The Burnout → Depression transition is structurally describable: Burnout (Type 1) depletes I. As I → 0, the system compensates by raising CL (withdrawal, rigidity) — which transitions structural dynamics from Type 1 to Type 2/3. The transition is not a matter of severity; it is a structural regime shift. This explains both the high empirical overlap (shared IR > 1 condition) and the neurobiological distinction (different variable configurations generating IR > 1). LP further demonstrates that the Maslach Burnout Inventory (MBI) — the dominant clinical instrument in burnout research — measures LP structural proxy variables without knowing it: exhaustion proxies I; cynicism proxies Frame erosion; reduced professional efficacy proxies IK. The existing clinical measurement apparatus is therefore already a partial LP proxy framework. LP provides the structural theory that explains why these three dimensions cluster as they do.
