Abstract
Systemic sepsis commonly produces brain dysfunction, sepsis-associated encephalopathy, which can vary from a transient, reversible encephalopathy to irreversible brain damage. The encephalopathy in the acute phase clinically resembles many metabolic encephalopathies: a diffuse disturbance in cerebral function with sparing of the brain stem. The severity of the encephalopathy, as reflected in progressive EEG abnormalities, often precedes then parallels dysfunction in other organs. Recent research has revealed a number of potentially important, non-mutually exclusive, mechanisms that have therapeutic implications. La septicémie induit communément une dysfonction cérébrale, l'encéphalopathie associée à la septicémie, dont la sévérité varie d'une encéphalopathie transitoire réversible au dommage cérébral irréversible. En phase aiguë, l'encéphalopathie ressemble cliniquement à plusieurs autres encéphalopathies métaboliques: une perturbation diffuse de la fonction cérébrale épargnant le tronc cérébral. L'encéphalopathie, comme en témoigne les anomalies progressives observées à l'ÉEG, précède souvent la dysfonction des autres organes puis évolue parallèlement à cette dysfonction. Des recherches récentes ont révélé plusieurs mécanismes potentiellement importants, qui ne sont pas mutuellement exclusifs et qui ont des implications thérapeutiques.Keywords
