Sepsis and the Systemic Cytokine Storm in Aging and Alzheimer Disease Models
ABSTRACT Severe infection and sepsis accelerate cognitive decline in older Americans, especially those with incipient Alzheimer's disease (AD). Sepsis is known to induce a systemic inflammatory `cytokine storm', which wanes with time. However, this response often persists even after infection resolution in patients. We hypothesize that this systemic cytokine storm can potentially affect brain neuropathology in both pre-symptomatic AD patients and in older adults with no known cognitive deficits. In preclinical AD models, both amyloid and tau protein accretion and pathology are influenced by systemic inflammation. Less is known about the cognitive decline in sepsis survivors without…
