What is Brain Aneurysm?

A brain aneurysm is a weak, bulging spot on the wall of an artery within the brain that can slowly enlarge over time and, if it ruptures, causes bleeding into the space surrounding the brain known as a subarachnoid hemorrhage. Most unruptured aneurysms cause no symptoms and are discovered incidentally on imaging done for other reasons, but a ruptured aneurysm constitutes a life-threatening medical emergency. The characteristic warning sign of rupture is a sudden, severe headache often described as the worst headache of one's life. Risk of rupture depends on the aneurysm's size, location, and shape.

What are the main symptoms of Brain Aneurysm?

The most common symptoms include: Often asymptomatic if unruptured; though larger unruptured aneurysms may cause localized headache; vision changes; or eye pain. Early recognition is key to prompt diagnosis and effective treatment.

Is Brain Aneurysm contagious?

No, Brain Aneurysm is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

How is Brain Aneurysm treated?

Treatment options include: Small; unruptured aneurysms with low rupture risk are often monitored with periodic imaging while risk factors like blood pressure and smoking are aggressively controlled. Larger or higher-risk aneurysms are treated preventively with minimally invasive endovascular coiling or surgical clipping to seal off the weakened vessel wall. A ruptured aneurysm requires emergency neurosurgical intervention; often coiling or clipping. Treatment should always be guided by a qualified Neurosurgery specialist. Do not self-medicate.

Can Brain Aneurysm be prevented?

While Brain Aneurysm cannot always be fully prevented, several measures can reduce risk: Controlling high blood pressure through medication and lifestyle changes; quitting smoking; limiting alcohol intake.

When should I see a doctor for Brain Aneurysm?

Seek immediate medical attention if you experience symptoms of Brain Aneurysm. This is a serious condition — go to the emergency room or call 112 if symptoms are severe or rapidly worsening.
