⚖️ Evidence

⚖️ Evidence Matrix4 supports4 contradicts
Supports
Patients with elevated baseline hs-CRP (>3 μg/mL) showed 2.3× faster cognitive decline and increased CSF tau
Supports
IL-1β drives tau hyperphosphorylation via GSK-3β activation in mouse models
Supports
CRP binds to phosphocholine on apoptotic cells, activating NLRP3 inflammasome and IL-1β release
Supports
Microglial MyD88 deletion attenuates tau pathology in PS19 mice
Contradicts
Mendelian randomization studies failed to demonstrate CRP genetic variants influence AD risk
Contradicts
Canakinumab (anti-IL-1β) trials showed no cognitive benefit despite CRP reduction - CANTOS trial was definitive negative
Contradicts
NSAIDs failed in AD prevention trials and may accelerate cognitive decline
Contradicts
IL1RN polymorphisms do not show consistent association with AD risk in genome-wide studies
