“…Here, endogenous factors, such as metabolic, cellular, cytotoxic, and vasogenic edema, and biochemical derangements as well as exogenous factors, such as hypoxia and hypotension, lead to neuronal cell degeneration and, ultimately, neuronal death (Kochanek et al, 2000). The goal in the acute injury phase is to improve cerebral perfusion and to stabilize the injured brain while promoting neuroprotection strategies to optimize functional outcomes (Anderson, Brown, & Newitt, 2010; Coronado, et al, 2011; Langlois, Rutland-Brown, & Thomas, 2004; Oh & Seo, 2009; Faul, Xu, Wald, & Coronado, 2010). This acute phase may occur for days to weeks in the injured brain, and it is within this time frame that the majority of the biomarker study research has occurred, because associating a biomarker with cascading protein activity may lead to identifying outcomes (Papa et al, 2013).…”
