A brain aneurysm, also known as a cerebral aneurysm, is a weak or thin spot in the wall of a blood vessel in the brain that balloons or bulges outward. Over time, this bulge can become thin and may leak or rupture, leading to a hemorrhagic stroke — a serious, potentially life-threatening condition.
How Does a Brain Aneurysm Develop?
Blood vessels in the brain can weaken due to factors like:
- High blood pressure (hypertension)
- Smoking
- Atherosclerosis (hardening of arteries)
- Genetic factors or family history
- Head injury or infection
- Certain medical conditions, such as connective tissue disorders
While anyone can develop a brain aneurysm, they are more common in adults, especially women aged 40–60.
Symptoms of a Brain Aneurysm
A small, unruptured aneurysm often causes no symptoms and may go unnoticed until it’s found during imaging for another reason.
However, a large or leaking aneurysm may cause:
- Severe, sudden headache (“the worst headache of your life”)
- Blurred or double vision
- Drooping eyelid
- Pain above or behind the eye
- Nausea and vomiting
- Loss of consciousness (in case of rupture)
If a rupture occurs, it’s a medical emergency that requires immediate treatment.
How Is It Diagnosed?
Doctors use imaging tests to detect aneurysms, such as:
- CT Scan or MRI – to identify bleeding or abnormalities
- Cerebral Angiography – to view blood flow and vessel structure in detail
Treatment Options
Treatment depends on the size, type, and location of the aneurysm:
- Surgical Clipping – a metal clip is placed around the aneurysm’s base to stop blood flow.
- Endovascular Coiling – a minimally invasive method where coils are placed inside the aneurysm to block blood flow.
- Monitoring – for small, stable aneurysms that aren’t causing symptoms.
Lifestyle changes like quitting smoking, managing blood pressure, and reducing stress are also crucial in preventing rupture.
Can a Brain Aneurysm Be Prevented?
While not all aneurysms are preventable, you can lower your risk by:
- Maintaining healthy blood pressure
- Avoiding smoking and excessive alcohol
- Eating a balanced, low-cholesterol diet
- Managing stress and chronic conditions
- Getting regular check-ups if you have a family history of aneurysms
🧠 Final Thoughts
A brain aneurysm can remain silent for years — but awareness and timely diagnosis can save lives.
If you experience sudden, severe headaches or neurological symptoms, seek emergency medical care immediately. Early detection is key to preventing complications and ensuring a healthy, safe recovery.
