Brain Insulin Resistance with Glucose Transporter Dysfunction proposes that neuronal insulin signaling failure — a central metabolic feature of Alzheimer's disease often called "type 3 diabetes" — drives neurodegeneration through impaired glucose transporter (GLUT3/GLUT4) trafficking, energy crisis, and compensatory metabolic shifts that exacerbate tau phosphorylation and amyloid pathology. **Background and Rationale** The brain consumes approximately 20% of the body's total glucose despite co

**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
