Bumrungrad Health Briefs #62: Brain Aneurysm: A Ticking Time Bomb?
A brain aneurysm is a weakened, bulging area in an artery supplying blood to the brain. Often silent, it can go undetected for years—until it ruptures, causing a life-threatening brain bleed known as a hemorrhagic stroke. A ruptured aneurysm requires immediate medical attention and can lead to severe brain damage or even death.
What Causes a Brain Aneurysm?
While the exact cause of brain aneurysms remains unclear, several factors contribute to their development:
- High blood pressure – Weakens artery walls over time, increasing rupture risk.
- Smoking – Damages blood vessels, making them more susceptible to bulging.
- Family history – Inherited genetic factors can predispose individuals to aneurysms.
- Head injury or infection – Trauma or infections may weaken blood vessel walls.
- Congenital disorders – Conditions like polycystic kidney disease or connective tissue disorders affect vascular health.
Signs & Symptoms
Most unruptured aneurysms do not cause noticeable symptoms. However, some may press on surrounding nerves, leading to:
- Persistent headaches
- Blurred or double vision
- Eye pain or a drooping eyelid
- Numbness or weakness in the face
If an aneurysm ruptures, symptoms appear suddenly and require emergency care:
- Severe headache (often described as "the worst headache of one’s life")
- Nausea and vomiting
- Seizures
- Loss of consciousness
Diagnosis & Treatment
Brain aneurysms are diagnosed using CT scans, MRI, or cerebral angiography. The right treatment depends on the size, location, and risk of rupture:
- Monitoring – Small aneurysms that show no signs of growth may be observed over time.
- Endovascular coiling – A minimally invasive procedure that seals off the aneurysm to prevent rupture.
- Surgical clipping – A procedure where a small metal clip is placed at the base of the aneurysm to block blood flow.
Reducing the Risk
- Control blood pressure through medication and lifestyle changes.
- Quit smoking and avoid excessive alcohol consumption.
- Adopt a healthy lifestyle with a balanced diet and regular exercise.
- Get screened regularly if you have a family history of aneurysms.
