What is the difference between cerebral thrombosis and cerebral embolism?

Cerebral thrombosis and cerebral embolism are all types of cerebral infarction, but there are obvious differences in pathogenesis. Cerebral thrombosis is mainly caused by cerebral atherosclerosis and cerebrovascular inflammation, while cerebral embolism is mainly caused by embolus shedding. Secondly, the onset of cerebral thrombosis is relatively slow, while the incidence of cerebral embolism is relatively acute.
