**Mechanistic Foundation** Specialized pro-resolving mediators (SPMs) - including resolvins, protectins, and maresins - are endogenous lipid mediators that actively terminate neuroinflammation and promote tissue repair. Unlike anti-inflammatory drugs that merely block inflammatory pathways, SPMs actively stimulate resolution programs: clearance of apoptotic debris, restoration of blood-brain barrier integrity, and regeneration of damaged neural tissue. In Alzheimer's disease, SPM biosynthesis i

**SASP-Mediated Complement Cascade Amplification in Alzheimer's Disease** **Overview: Senescence, Inflammation, and Synaptic Loss** Cellular senescence—a state of irreversible growth arrest accompanied by a pro-inflammatory secretome—accumulates dramatically with age and in Alzheimer's disease. Senescent astrocytes and microglia secrete the senescence-associated secretory phenotype (SASP), a cocktail of cytokines, chemokines, proteases, and critically, complement cascade initiators including C
