There is no effective method to prevent cerebral aneurysm. For those who have hypertension, hyperlipidemia, hyperglycemia, smoking, or family members with aneurysm, it is important to have regular imaging review when 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, so it is necessary to go to the hospital immediately for examination and treatment.
