There is no effective method to prevent brain aneurysms. For those who have hypertension, high blood pressure, high blood sugar, smoking, or family members with aneurysms, it is important to have regular imaging reviews when an aneurysm is found so that timely treatment can be given before the aneurysm ruptures and bleeds. At the same time, patients with cerebral aneurysm should maintain emotional stability, regular rest and rest, avoid overexertion, strenuous exercise, and keep bowel and urine open. If a severe headache occurs, it is likely that the aneurysm is ruptured and bleeding, and needs to be checked and treated in hospital immediately.
