Is cerebral embolism the same as cerebral infarction?

Cerebral embolism and cerebral infarction are different. Their differences mainly lie in the following aspects: 1. Different causes:

Cerebral embolism refers to emboli entering intracranial arteries along with blood flow to cause acute occlusion of vascular lumen, causing ischemic necrosis of brain tissue and brain dysfunction in corresponding blood supply areas. The main sources of emboli are cardiogenic, non-cardiogenic and unknown. Cerebral infarction refers to ischemic necrosis or softening of localized brain tissue caused by cerebral blood circulation disorder, ischemia and hypoxia. Mainly related to atherosclerosis, followed by arteritis, drug-induced, trauma and other physical factors, blood diseases and various emboli, etc. 2. Different symptoms: cerebral embolism onset acute, in a few seconds or minutes symptoms reach a peak, is the most acute of all stroke, no prodromal symptoms. Common symptoms include hemiplegia, aphasia, hemiparesthesia, coma, etc. The symptoms of cerebral infarction are relatively slow, often reaching a peak within hours to days. Common symptoms include hemiplegia, aphasia, hemiparesthesia, ataxia, etc. 3. Different treatment methods: The treatment of cerebral embolism mainly includes thrombolysis, anticoagulation, anti-platelet aggregation, brain protection, etc. For large areas of cerebral embolism or cerebral hernia, surgery may be required. Treatment of cerebral infarction mainly includes thrombolysis, anticoagulation, anti-platelet aggregation, improvement of circulation, neuroprotection, anti-cerebral edema, surgical treatment, etc. 4. Prognosis: The prognosis of cerebral embolism depends on the location, scope, source of embolus and other factors. Generally speaking, the prognosis of cerebral infarction is poor, and the mortality and disability rate are high. The prognosis of cerebral infarction depends on factors such as the location and extent of infarction, the age of the patient, and the concomitant diseases. Generally speaking, the prognosis of cerebral infarction is better than that of cerebral embolism, but if the infarction area is large or serious complications occur, the prognosis may be poor. In short, although cerebral embolism and cerebral infarction are cerebrovascular diseases, their causes, symptoms, treatment methods and prognosis are different.
