Prevention and Treatment of Cerebrovascular Disease Intracranial aneurysms are abnormal bulging portions of the cerebral artery wall and are a common cause of spontaneous subarachnoid hemorrhage. The cause of the disease is not well understood, but congenital aneurysms account for the majority of cases. They can develop at any age and are common between 40 and 66 years of age. Intracranial aneurysms have been described as untimely bombs in the skull, so what factors can influence the triggering of their rupture? What are the causes of ruptured cerebral aneurysms? Anxiety, stress, excitement, sudden rise in blood pressure, urination and defecation, exertion, late pregnancy, childbirth, physical labor, sexual intercourse, etc. are all triggering factors for aneurysm rupture. Many patients have pioneering symptoms such as paroxysmal headache, eye muscle paralysis, diplopia, dizziness, and neck pain before bleeding, indicating that the aneurysm wall has been pathologically altered before rupture, and the rupture of the aneurysm wall that has already ruptured occurs in the presence of triggering factors. In many cases, bleeding occurs suddenly without any obvious cause. Is it true that so many factors are involved? Of course healthy living is something we want to promote, and we identify representative factors for analysis.
