The main difference between cerebral thrombosis and cerebral infarction lies in the following two points: I. Different pathogenesis: 1. Cerebral thrombosis: is a condition caused by atherosclerosis, endarteritis and high blood viscosity, resulting in the local formation of thrombus in cerebral vessels and blocking the blood vessels. 2. Cerebral infarction: is a condition caused by emboli in other parts of the blood vessels, such as the attached wall thrombus of heart disease, the thrombus of aorta and carotid artery in the form of atherosclerotic plaque dislodged. pelvic and lower extremity venous thrombus dislodged, fat embolism when fracture, etc. run to the brain to cause vascular embolism when the disease occurs, mostly in patients with heart disease. Second, clinical symptoms vary: 1, cerebral thrombosis: cerebral thrombosis starts slowly and often develops during sleep or rest. Some patients have mild symptoms at first, and then gradually worsen, and even reach the peak 2 to 3 days after the disease. Patients with coma are less common and generally have mild symptoms, may have hemiparesis or unilateral limb paralysis, may also have aphasia, and some patients have symptoms such as head or limb numbness. 2. Cerebral infarction: The disease has an acute onset and often causes aphasia and hemiplegic sensory impairment mainly in the right upper limb, but coma rarely appears.
