**Mechanistic Foundation** Senescent microglia represent a distinct pathological cell state in Alzheimer's disease and aging that combines features of cellular senescence (growth arrest, senescence-associated secretory phenotype/SASP) with impaired microglial-specific functions (phagocytosis, surveillance, synaptic pruning). These "zombie" microglia accumulate in aged and diseased brains, constituting up to 30% of the microglial population in advanced Alzheimer's disease. Unlike reversibly acti

**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
