Neurology of Sepsis.

Sepsis is a systemic inflammatory response syndrome occurring secondary to infection and labeled severe when end organ dysfunction or tissue hypoperfusion transpires. Sepsis-associated mortality remains high among critically ill patients, with chronic disease and immunosuppression being the most common risk factors. Studies demonstrate that early recognition and treatment are vital to decreasing mortality. Some of the least understood effects of sepsis are the associated neurologic complications. The peripheral nervous system (PNS) has gained most consideration and thought, largely due to dependence on mechanical ventilation. Central nervous system (CNS) complications related to sepsis have only more recently gained attention but continue to go unnoticed. Aside from the clinical examination, electroencephalography (EEG) is a sensitive tool for prognostication or uncovering non-convulsive seizures in encephalopathic patients. Further studies are needed to further define the urgency of a prevention and treatment plan for the deleterious effects of sepsis on the PNS and CNS.
