The difference between stroke and cerebral infarction lies in the scope of stroke, which is broader and includes cerebral infarction. Stroke is divided into hemorrhagic stroke and ischemic stroke. Common types of hemorrhagic stroke include cerebral hemorrhage and subarachnoid hemorrhage. Common types of ischemic stroke include cerebral infarction and cerebral thrombosis. Thus, the scope of stroke is relatively large and includes cerebral infarction. Cerebral infarction occurs when a blockage in the cerebral blood vessels leads to ischemia, edema, and necrosis of the brain tissue in the supplied area, resulting in symptoms of stroke. Additionally, cerebral embolism occurs when an embolus from another part of the body detaches and blocks a brain artery, causing ischemia and necrosis of the brain tissue in the supplied area, also leading to stroke.
