This synthesis tests the thesis that evidence for Brain age MRI is context-dependent, separating outcome-specific signals from broader claims and identifying the evidence gaps that should bound interpretation. This paper synthesizes brain age mri as an aging-related intervention across 64 included source papers and 2040 high-confidence extracted claims. The evidence profile contains no sources classified primarily as direct clinical evidence, 37 adjacent clinical sources, and no sources classified primarily as mechanistic or model-system evidence, with 1293 cross-study disagreements across the evidence base. Positive study-level signals concentrate in cardiometabolic, null signals in contextual adjacent evidence, cardiometabolic, safety and comorbidity, and negative signals in cardiometabolic. The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect. The conclusion is that brain age mri remains a bounded geroscience case: mechanistic plausibility and selected clinical signals justify further targeted testing, while mixed and null findings limit any unqualified anti-aging claim.
