Understanding a Brain Aneurysm
A brain aneurysm is a weak area in the wall of a blood vessel inside the brain that begins to bulge outward like a balloon. Over time, pressure from blood flow can make this area thinner and more fragile.
If it ruptures, it can cause internal bleeding in the brain — a serious condition known as subarachnoid hemorrhage — that requires immediate medical attention.
While many aneurysms never rupture and may remain symptom-free, identifying and managing them early can prevent life-threatening complications.
Recognizing the Symptoms
Unruptured Aneurysm
Most unruptured aneurysms go unnoticed, but if they grow large or press on nearby brain tissue or nerves, you might experience:
Frequent or unusual headaches
Vision disturbances (blurring or double vision)
Pain near or behind the eyes
Numbness or weakness on one side of the face
Trouble with balance or speech
Ruptured Aneurysm
When an aneurysm bursts, symptoms appear suddenly and can be severe. Common warning signs include:
A sudden, intense headache often described as “the worst headache of my life”
Nausea or vomiting
Neck stiffness
Blurred or double vision
Sensitivity to light
Seizures or fainting
Loss of consciousness
A ruptured aneurysm is a medical emergency — seek immediate help if these symptoms occur.
Causes and Risk Factors
A brain aneurysm can develop due to several reasons. Some are related to lifestyle choices, while others are linked to genetics or underlying health conditions. Common risk factors include:
Long-term high blood pressure
Smoking or alcohol use
Family history of aneurysms
Aging and natural weakening of arteries
Head injury
Certain vascular or connective tissue disorders
Managing blood pressure, avoiding tobacco, and leading a healthy lifestyle are key preventive steps.
How Doctors Diagnose a Brain Aneurysm
If a brain aneurysm is suspected, doctors use advanced imaging to confirm the diagnosis and assess its size and location. Common tests include:
CT Scan: Detects bleeding and structural damage.
MRI / MRA: Creates detailed images of brain tissues and blood vessels.
Cerebral Angiography (DSA): Provides the most precise view of blood vessel anatomy for accurate treatment planning.
These tests help determine whether the aneurysm needs observation or active intervention.
Treatment Options
The best treatment approach depends on whether the aneurysm has ruptured and how likely it is to bleed in the future.
1. Monitoring and Preventive Care
For smaller, stable aneurysms, doctors may recommend regular imaging, medication for blood pressure control, and healthy lifestyle changes to minimize risk.
2. Endovascular Therapy (Minimally Invasive)
In this advanced procedure, a thin catheter is inserted through the blood vessels to reach the aneurysm. Coils, stents, or flow-diverters are placed inside the vessel to block blood flow into the aneurysm.
This method is less invasive, requires no major surgery, and allows for quicker recovery.
3. Microsurgical Clipping
In cases where endovascular treatment isn’t suitable, open surgery may be performed to place a small clip at the base of the aneurysm. This prevents further blood flow into the weakened area and permanently seals it off.
Recovery and Outlook
Recovery time varies based on whether the aneurysm ruptured and how early it was treated.
Unruptured aneurysms that are treated promptly often result in full recovery.
Ruptured aneurysms may require longer rehabilitation but can still achieve good outcomes with timely, expert care.
Continuous follow-ups and adopting a heart- and brain-healthy lifestyle are essential parts of long-term management.
