There is no big difference between the clinical manifestations of cerebral hemorrhage and cerebral embolism, both of which are characterized by neurological deficits, and the patients may have hemiparesis, stupefaction and aphasia. Patients may have hemiparesis, dysarthria, aphasia, impaired consciousness or epileptic seizures, and in severe cases, headache, nausea, vomiting, etc. The diagnosis can be confirmed after CT or MRI examination of the head. However, there is a difference between the treatment of cerebral hemorrhage and cerebral embolism. For cerebral hemorrhage, dehydration and lowering of cranial pressure are the main focus, and if necessary, drilling and drainage or craniotomy can be performed. For the acute stage of cerebral embolism, symptomatic treatment such as thrombolysis, mechanical extraction of thrombus, anticoagulation, descending fiber or anti-platelet aggregation can be given. For cerebral hemorrhage or cerebral embolism, patients are advised to look for the cause of the disease and at the same time to initiate secondary prevention of cerebrovascular disease.
