Biomarkers associated with delirium in critically ill patients and their relation with long-term subjective cognitive dysfunction : Indications for different pathways governing delirium in inflamed and noninflamed patients

Delirium occurs frequently in critically ill patients and is associated with disease severity and infection. Although several pathways for delirium have been described, biomarkers associated with delirium in intensive care unit (ICU) patients is not well studied. We examined plasma biomarkers in delirious and nondelirious patients and the role of these biomarkers on long-term cognitive function.
