What is ischemia of the brain?

As a medical professional with expertise in neurology, I can explain that cerebral ischemia is a serious medical condition characterized by a reduction in blood flow to the brain. This reduction can be due to various factors, including the narrowing or blockage of the blood vessels that supply the brain with oxygen and nutrients. When the brain doesn't receive enough blood, it can lead to cerebral hypoxia, which is a deficiency in the amount of oxygen reaching the brain's tissues. The consequences of cerebral ischemia can be severe, ranging from transient symptoms like dizziness and confusion to more serious outcomes such as brain tissue death, which is known as cerebral infarction or an ischemic stroke. An ischemic stroke occurs when the blood supply to part of the brain is completely blocked, leading to the death of brain cells in the affected area. It's important to note that the severity and symptoms of cerebral ischemia can vary greatly depending on the extent of the blood flow reduction and the specific area of the brain affected. Treatment typically involves addressing the underlying cause of the ischemia, such as managing blood pressure, improving blood flow through medications, or even surgical procedures to remove blockages.

cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke.
