The age of 35 is a relatively young age, so the probability of cerebral infarction in the normal population is low, but in recent years more and more young patients have cerebral infarction. What about young patients prone to cerebral infarction: 1, a large number of smoking history: a large number of smoking can cause early atherosclerosis of the arteries to form clots; 2, with diabetes and hypertension, uncontrolled diabetes and hypertension can seriously accelerate the formation of atherosclerosis, which leads to the occurrence of cerebral infarction; 3, heart disease: cerebral infarction in young patients often combined with heart disease, with severe arrhythmias, Cardiomyopathy and heart valve disease, which block the flow of blood in the heart to form clots, thus blocking blood vessels; 4. Drug addiction: young patients who often have a history of drug addiction are prone to cerebral infarction; 5. Hereditary cerebrovascular disease: such as CADASIL, patients often show symptoms such as cerebral infarction, headache and cognitive impairment, often accompanied by a family history.
