Abstract

With the onset of profound cerebral ischemia, a complex chain of events is set into motion. If there is no intervention, irreversible damage occurs within several minutes. Although the primary insult of cerebral ischemia is a reduction in the supply of major nutrients, the depletion of cellular energy stores soon triggers a series of secondary events known as the “ischemic cascade.” However, numerous factors influence the course of cerebral ischemia, and cell death is not necessarily the inevitable outcome. A simplified scheme of the progression of cerebral ischemia, with identification of possible sites for treatment, is presented in Figs. 1–3.
