Cerebral Ischemia, or also referred to as rain ischemia, is a condition that happens when there isn’t enough blood flowing to the brain to meet metabolic demand. This leads to limited oxygen supply or cerebral hypoxia and leads to the death of brain tissue, cerebral infarction, or ischemic stroke. It’s a sub-type of stroke along with subarchnoid hemorrhage and intracerebral hemorrhage.
There are two kinds of ischemia:
- focal ischemia: confined to a certain region of the brain
- global ischemia: encompasses wide areas of brain tissue
