Also called intracranial, cerebral or berry aneurysm, the aneurysm forms because an artery in the brain has a weak spot. The weak and vulnerable spot will balloon or bulge as blood pumps through the brain’s blood vessel. The “ballooning” will create aneurysms.

Introduction to Brain Aneurysm: Causes, Symptoms, Diagnosis, Treatment, and Prognosis

A brain aneurysm is a ballooning or bulge in a blood vessel in the brain. This post provides essential information on brain aneurysms—their causes, symptoms, diagnosis, treatment, and prognosis. Finally, we will suggest some basic lifestyle practices that will help prevent a brain aneurysm.


What Are the Causes of a Brain Aneurysm?

Although the exact causes of a brain aneurysm aren’t always clear, several factors can contribute to the ballooning caused by the weakening of blood vessel walls. Those underlying causes include:

  • high blood pressure, or hypertension
  • a family history of brain aneurysms
  • the age and gender of the patient
  • smoking and drug abuse
  • atherosclerosis—plaque buildup in the arteries
  • in rare cases, head injury or infection of the blood vessel walls

You were born with some causes and risk factors while others can be changed.

What are the Symptoms of a Brain Aneurysm?

Typically, you will experience symptoms once the blood vessel actually ruptures or becomes large enough to press up against surrounding structures in the brain. However, symptoms will depend on the size of the aneurysm, its location, and whether or not the aneurysm has ruptured.

Unruptured Brain Aneurysm Symptoms Include:

  • Numbness or weakness on one side of the face
  • A drooping eyelid
  • Headache
  • Blurred or double vision
  • Dilated pupil of one eye
  • Pain behind and above one eye

Ruptured Brain Aneurysm Symptoms Include:

  • As in an unruptured brain aneurysm, blurred or double vision
  • A severe, sudden headache, which patients often describe as the “worst headache of their life”
  • Nausea and/or vomiting
  • Stiffness in the neck
  • Extreme sensitivity to light
  • Seizures
  • Loss of consciousness
  • Altered mental state or confusion

Note: If you believe someone displays symptoms of a ruptured brain aneurysm, you must seek medical assistance immediately. Timely diagnosis and treatment can improve the chances of survival and reduce severe complications due to a debilitating stroke, for example. Learn more about the key differences between an unruptured and ruptured brain aneurysm.


How is a Brain Aneurysm Detected/Diagnosed?

The neurologist and neurosurgeon rely on a variety of imaging tests. The images produced by the following methods visualize the blood vessels in the brain to detect abnormalities:


  1. MRI (Magnetic Resonance Imaging)—uses a magnetic field and radio waves to generate detailed images
  2. MRA (Magnetic Resonance Angiography)—a type of MRI that uses a contrast dye to detect and analyze aneurysms in the brain
  3. Cerebral Angiogram—an invasive test where a specially trained physician inserts a catheter into an artery in the patient’s groin and guides the catheter to the blood vessels in the brain, followed by injection of a contrast dye and X-ray images.

What is the Treatment Plan Employed by a Brain Doctor Near Me for Brain Aneurysm?

Treatment depends on the size, location, and whether the aneurysm has ruptured. The plan can be as simple as monitoring for a small unruptured, asymptomatic aneurysm. The monitoring can include blood pressure, pain control, or seizure prevention medication. Other more invasive treatments include endovascular coiling and surgical clipping to block blood flow to weakened blood vessels in the brain.

We provide brain aneurysm care and treatment options at our specialized brain aneurysm clinic at Supreme Vascular and Interventional Clinic in Singapore.


What is the Prognosis of a Brain Aneurysm?

As in the treatment plan, the prognosis depends on the size, location, and whether the aneurysm has ruptured. Unruptured aneurysms have an increased risk of complications.


What is the Most Effective Prevention of a Brain Aneurysm? 

According to the Mayo Clinic and other sources, the best preventive measures to reduce the risk of a brain aneurysm include the following 7 basic lifestyle practices:

  1. Monitor your blood pressure
  2. Manage stress
  3. Don’t use tobacco
  4. Limit alcohol consumption
  5. Maintain a healthy diet
  6. Exercise regularly
  7. Maintain a healthy weight

Supreme Vascular and Interventional Clinic Treatments

There are more several types of neurointerventional treatments we offer to treat different problems including brain aneurysm. Swipe to learn more.

Brain Aneurysm

Brain aneurysm is bulging or ballooning of a blood vessel supplying the brain. Brain aneurysms are present in 1 to 2% of population. The commonest age group affected is 40-60 years.

Brain aneurysms can cause non-specific neurological symptoms such as headaches, double vision, and more.

Stroke Screening

Stroke is one of the leading causes of death worldwide. It is also the leading cause of long term disability with debilitating and devastating consequences for both patients and family. One of the most recognizable outcomes of stroke is paralysis affecting a part or half of the body.

There are different types, grades and location of AVM in the brain. The symptoms that patients present with depend on these above factors.

Stroke Management and Prevention

Stroke is one of the most common conditions causing death worldwide. There is high incidence of permanent brain damage severely affecting quality of life in affected patients. It can be a devastating event both for patient and the family.

The best way to treat a stroke is to prevent stroke. There are well known causes of stroke such as high blood pressure, high cholesterol level, poor controlled diabetes and smoking.


Headache is a very common condition that affects virtually everyone. Some individuals have more debilitating headaches than the others severely affecting their quality of life.

The two commonest type of headaches seen in clinical practice are migraine and tension headache. There are other causes of headache that may be caused by underlying structural issues in the brain or by other physiological issues affecting the structures of the brain.

What is Neurointerventional Treatment?

Neurointerventional treatments are performed to treat different problems that occur in the brain, spine, head, and neck. Neurointerventionalists use small instruments and catheters to go through blood vessels in your body to reach the affected area. This is done with the help of advanced imaging technology like CT and MRI scans to ensure precise treatment.

Introduction to Brain AVM

Brain arteriovenous malformation (AVM) is an uncommon condition that is due to abnormal connection between arteries and veins in the brain substance. Almost 60% patients diagnosed with this condition are below 40 years of age.

There are different types, grades and location of AVM in the brain. The symptoms that patients present with depend on these above factors.

Carotid Stenting

Carotid artery is the artery in the neck supplying blood to the brain from the heart. Atherosclerosis of the carotid artery is responsible for causing stroke in about 20% of all patients with stroke worldwide.

Atheromatous deposits and plaques cause blockage of blood supply to the brain in high risk individuals. 

Intracranial Stenting

Intracranial Stenting is a less commonly known technique to treat stroke or prevent stroke. Blockage of blood vessels to the brain is a common cause of stroke in Asian population affecting up to 25% of patients presenting with acute stroke or transient ischemic attack (TIA) which is a precursor of stroke.

Acute stroke is a “brain attack” and there are two main causes, a blocked artery or leaking or bursting of a blood vessel.

Head and Neck Vascular Malformations

Vascular malformations are a complex spectrum of conditions with commonly used names being venous malformation, arteriovenous malformation, arteriovenous fistula, lymphatic malformation, hemangioma, lymphangioma.

Vascular malformation is an abnormal collection of blood vessels that can occur anywhere in the body.
