Cerebral thrombosis and cerebral hemorrhage have essential differences, including pathogenesis, onset time, symptoms, etc., as follows: a. Pathogenesis is different: cerebral thrombosis refers to ischemic cerebrovascular disease, while cerebral hemorrhage is hemorrhagic cerebrovascular disease. After the cerebrovascular rupture, hemorrhage will form a hematoma in the brain, and the cerebral nerve and brain tissue will be compressed and symptoms will appear. Cerebral infarction is caused by thrombosis of cerebral blood vessels, resulting in acute blood flow interruption, causing necrosis of cerebral nerves and brain tissues and the formation of symptoms; second, the onset time is different: cerebral hemorrhage may occur when emotional excitement or exertion, while patients with cerebral infarction and cerebral thrombosis are mostly in a quiet state; third, the symptoms are different: the degree of cerebral hemorrhage is heavier, patients will show a sudden occurrence of more severe headache The symptoms of cerebral hemorrhage are different: if the degree of cerebral hemorrhage is more serious, the patient will have a sudden and severe headache, accompanied by jet-like nausea and vomiting, or appearing consciousness disorder and coma. The symptoms of cerebral thrombosis are mainly unfavorable limb movement, clumsy language, and other neurological deficits, unless it is a large cerebral infarction, which will lead to severe headache. The risk factors for cerebral thrombosis are mainly due to hypertension, diabetes, and hyperlipidemia, which are related to the occlusion of arteriosclerotic thrombi in blood vessels.
