Hypoxia-Ischemia, Brain
| Definition: |
A disorder characterized by a reduction in oxygen supply (HYPOXIA) combined with reduced blood flow (ISCHEMIA) to the brain. This condition may result from a localized obstruction of a cerebral artery or from systemic hypoperfusion. Prolonged hypoxia-ischemia is associated with ISCHEMIC ATTACK, TRANSIENT; BRAIN INFARCTION; BRAIN EDEMA; COMA; and other conditions. |

Hypoxia, Brain - A reduction in brain oxygen supply. Severe hypoxia is referred to as anoxia, and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives. (From Adams et al., Principles of Neurology, 6th ed, pp1109-11) |
