Difference between cerebral infarction and cerebral hemorrhage and cerebral embolism

Cerebral infarction and cerebral hemorrhage and cerebral embolism are different, cerebral infarction is because cerebral blood vessels appear blocked or narrow, cerebral embolism is because other parts of embolus fall off, leading to cerebral blood vessel obstruction caused by brain tissue necrosis disease, and cerebral hemorrhage refers to cerebral blood vessel rupture hemorrhage.
