Brain ischemia. Brain ischemia (a.k.a. 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.
Every organ needs blood flow (i.e. perfusion) to function properly. The kidney is very sensitive to lack of perfusion, and damage can occure quickly if there is not sufficient perfusion. In fact, if the perfusion is not satisfactory, the kidney can 'simulate' a rise in BP (see the renin-angiotensin-aldosterone axis).
