Septic-associated encephalopathy--everything starts at a microlevel

Crit Care. 2010;14(5):199. doi: 10.1186/cc9254. Epub 2010 Sep 29.

Abstract

Sepsis-associated encephalopathy is associated with increased mortality and morbidity. Its pathophysiology remains insufficiently elucidated, although there is evidence for a neuroinflammatory process sequentially involving endothelial activation, blood-brain barrier alteration and cellular dysfunction and alteration in neurotransmission. Experimental studies have shown that microcirculatory dysfunction, a consequence of endothelial activation, is an early pathogenic step. To date, we do not know whether it is present in septic patients, whether it accounts for clinical features and whether it is treatable.
