Brain Aneurysm: An Overview
A brain aneurysm, sometimes a cerebral aneurysm is a bulge or ballooning of a blood artery in the brain. If it bursts, it can cause significant health consequences, including brain bleeding (hemorrhagic stroke). Understanding the various forms, symptoms, causes, risk factors, diagnosis, and treatment choices is critical for successfully managing this condition.
Types of Brain Aneurysm
There are three main types of brain aneurysms:
- Saccular Aneurysm (Berry Aneurysm): This is the most common type, characterized by a round, berry-like shape. It typically occurs at the bifurcations or branches of bigger arteries at the base of the brain.
- Fusiform Aneurysm: This type involves a widening along all sides of the artery, leading to a spindle-shaped enlargement. Fusiform aneurysms are less common and typically do not rupture as easily as saccular aneurysms.
- Mycotic Aneurysm: Caused by an infection, these aneurysms are rare and occur when an infected embolus lodges in the arterial wall, leading to the formation of an aneurysm.
Severe traumatic brain injury (TBI) has been one of the major causes of death. In India, the incidence of head injury is steadily increasing with urbanization and an increasing vehicular population. Among road traffic accidents, 70% have a head injury, and among road accident deaths 70% are due to head injury. Most deaths occur during the first 72 hours.

Get A Second OpinionSymptoms for Brain Aneurysm
Many brain aneurysms do not cause symptoms until they become large or rupture.
Symptoms of an unruptured aneurysm may include:
- Severe headache
- Vision changes
- Pain above or behind the eye
- Numbness or weakness on one side of the face
- Difficulty speaking
If an aneurysm ruptures, symptoms can be sudden and severe, such as:
- Sudden, extremely severe headache (often described as the worst headache ever experienced)
- Nausea and vomiting
- Stiff neck
- Sensitivity to light
- Seizures
- Loss of consciousness
Causes for Brain Aneurysm
The specific cause of brain aneurysms is unknown, however various factors may contribute to their formation:
- Genetic Factors: A family history of brain aneurysms can increase the risk.
- Medical Conditions: Polycystic renal disease, aortic coarctation, and connective tissue disorders can all increase the risk of aneurysms.
- Trauma: Head injury or trauma can damage blood vessels, leading to aneurysm formation.
- Infection: Infections of the arterial wall can lead to mycotic aneurysms.
Risk Factors of Brain Aneurysm
Several risk factors may increase the likelihood of having a brain aneurysm:
- Age and Gender: Aneurysms are more common in adults and women.
- Smoking: Tobacco use significantly increases the risk.
- High Blood Pressure: Chronic hypertension can weaken blood vessel walls.
- Alcohol and Drug Use: Excessive alcohol consumption and drug abuse, particularly cocaine, can elevate the risk.
Diagnosis for Brain Aneurysm
Diagnosing a brain aneurysm typically involves imaging studies, which may include:
- CT Scan : Produces comprehensive images of the brain and detects bleeding.
- MRI : Offers high-resolution images and is helpful in identifying aneurysms. Cerebral Angiography is a specialist X-ray diagnostic in which a contrast dye is injected into the bloodstream to reveal blood arteries in the brain.
- CT Angiography (CTA) and MR Angiography (MRA) : Non-invasive imaging techniques that combine standard CT or MRI with contrast dye to get detailed views of blood vessels.
Treatments for Brain Aneurysm
Treatment for a brain aneurysm is determined by its size, location, and risk of rupture. Options include:
- Monitoring: Small, unruptured aneurysms that do not cause symptoms can be monitored with regular imaging scans while risk factors are controlled.
- Medications: Drugs to manage high blood pressure and prevent seizures may be prescribed.
- Surgical Clipping: A procedure where a neurosurgeon places a metal clip at the base of the aneurysm to stop blood flow into it.
- Endovascular Coiling: A less invasive procedure where coils are inserted via a catheter to induce clotting within the aneurysm, preventing rupture.
- Flow Diversion: A newer technique where a stent is placed within the artery to divert blood flow away from the aneurysm.
Conclusion
A brain aneurysm is a potentially life-threatening condition that requires careful monitoring and, in some cases, urgent treatment. Awareness of the types, symptoms, causes, risk factors, and diagnostic methods is essential for timely and effective management. If you or someone you know experiences symptoms indicative of a brain aneurysm, seek medical attention immediately.

There are two types of aneurysms. One is called a saccular cerebral aneurysm and the other is called a fusiform aneurysm.
A saccular cerebral aneurysm is also known as a berry aneurysm because of its shape. A saccular cerebral aneurysm is the most common form of subarachnoid hemorrhage. The saccular cerebral aneurysm has a stem and a neck
The second one is a fusiform aneurysm and it does not have a stem.

Symptoms of an aneurysm can vary depending on its location and size, but common indicators include a sudden, severe headache, pain in areas like the abdomen, chest, or back, nausea, vomiting, dizziness, sensitivity to light, blurred vision, difficulty speaking, weakness or paralysis on one side of the body, and sometimes a pulsating mass in the abdomen. These symptoms, especially a severe headache, require immediate medical attention.

A brain aneurysm is a bulge in a weak spot of a blood vessel in or around the brain. While most are small and harmless, a ruptured one can be life-threatening. The primary symptom of a rupture is an intense headache, often described as the worst ever. If you experience these symptoms, seek immediate medical attention.

As we all know that there are three types of a brain aneurysm.
- Abdominal Aortic Aneurysm is mostly seen in men who are above the age of 60. Aorta sends the blood vessel to the different parts of the body like legs, abdomen, pelvis. Abdominal Aortic Aneurysm is seen when the area of the aorta becomes very large.
- Cerebral Aneurysm is where the blood vessels start widening within the brain. The word aneurysm has derived from the Greek word “Aneurysma” means ‘widening’. Cerebral Aneurysm is mainly affected due to high blood pressure or headache.
- Thoracic Aortic Aneurysm occurs in the largest artery that passes through the chest. People with high cholesterol and high blood pressure and who smoke are generally suffering from thoracic aortic aneurysm.

If you are suffering from any kind of symptoms related to brain aneurysm you have to go for some of the tests in order to know which kind of brain aneurysm is. Some of the diagnostic tests which are suggested by our doctors are
- Computerized Tomography is also known as CT Scan. If you are having bleeding in the brain. This test is mainly done to know the blood flow in the brain.
- Cerebrospinal fluid test: If the CT Scan has not shown any evidence of bleeding but you are suffering from the symptoms of aneurysm then the doctor may suggest a cerebrospinal fluid test.
- Magnetic Resonance Imaging: In order to create detail images of the brain either 2-D or 3-D Magnetic Resonance Imaging uses magnetic fields and radio waves.
- Cerebral Angiogram is also known as Cerebral Arteriogram. During this process, the doctors used to insert a thin, flexible tube into a larger artery.

The main goal of brain aneurysm treatment is to stop or reduce the flow of blood into the aneurysm. A leaking or ruptured brain aneurysm requires emergency surgery
