Patients who have had a brain hemorrhage are much more likely to have another brain hemorrhage than the normal population. Population-based surveys have shown that patients have a 2.1%-3.7% risk of recurrence after their first cerebral hemorrhage. Risk factors closely associated with recurrence of cerebral hemorrhage include the presence of hypertension, lobar hemorrhage (suggesting a high likelihood of cerebral amyloid angiopathy), advanced age, alcohol consumption, and receipt of anticoagulant therapy. The timing of recurrence varies depending on how many risk factors the patient has; the more risk factors there are, the greater the risk of recurrence and the more frequent it is. The key to prevent recurrence of cerebral hemorrhage is etiologic treatment, of which hypertension is the most important controllable risk factor, and active control of hypertension can effectively reduce recurrence of cerebral hemorrhage. For patients with previous history of hypertension, blood pressure should be strictly controlled; for diabetic patients, blood sugar should be strictly controlled to prevent re-bleeding in the brain due to small vessel lesions; for patients with structural abnormalities of cerebral vessels (aneurysm, vascular malformation, smoker’s disease, arteriovenous fistula, etc.), the above lesions need to be treated and surgery or endovascular intervention can be considered. In order to prevent recurrence of cerebral hemorrhage, all patients should check the etiology of cerebral hemorrhage, look for their possible problems, including bad habits (smoking, alcoholism, staying up late, etc.), make timely adjustments and strictly control them, and believe that the chances of recurrence of cerebral hemorrhage will be greatly reduced. Therefore, cerebral hemorrhage is a serious category of cerebrovascular diseases, and the risk of recurrence is always present due to the existence of the basis of vascular lesions, and there is no absolute safety. However, cerebral hemorrhage can be effectively prevented with increased attention, active prevention, early detection and timely treatment.
