Reduced brain blood flow can lead to dizziness, lightheadedness, and, sometimes, loss of consciousness. It can occur when getting up rapidly because blood pools in the abdomen and legs due to gravity if something interrupts the normal mechanisms that help return blood back up to the heart and brain.
Brain ischemia (aka 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. closely related disease to brain ischemia is brain hypoxia. Brain hypoxia is the condition in which there is a decrease in the oxygen supply to the brain even in the presence of adequate blood flow.
