Is a brain aneurysm serious?

Brain aneurysms are generally serious conditions, typically resulting from abnormal bulging due to intracranial vascular malformations. They carry a risk of rupture leading to intracranial hemorrhage, which may cause severe headache, coma, or even death. Therefore, they require high vigilance and timely intervention. If sudden severe headache, vomiting, or altered consciousness occurs, immediate medical attention is recommended.

Unruptured brain aneurysms may compress surrounding brain tissue, causing symptoms such as seizures, vision loss, or limb numbness. Once ruptured, they can lead to subarachnoid hemorrhage or intracerebral hematoma, rapidly increasing intracranial pressure and damaging neurological function. Some patients may suffer permanent disabilities, and life-threatening complications can occur within a short time.

The severity of a brain aneurysm depends on its size and location. Aneurysms located in critical areas such as the brainstem or those of larger size pose higher risks of rupture and more severe consequences. In contrast, smaller aneurysms in more superficial locations carry relatively lower risks, but still require regular monitoring. In all cases, imaging studies are essential for accurate diagnosis and to guide individualized treatment plans.

In daily life, it is important to maintain emotional stability, avoid intense physical activity, excessive fatigue, or emotional excitement, keep blood pressure within a normal range, maintain regular sleep patterns without staying up late, minimize potential triggers for aneurysm rupture, and adhere to scheduled follow-up examinations.
