What is a Cerebral Aneurysm?

A cerebral aneurysm is a weak spot in a blood vessel in the brain that bulges outward. This bulge fills with blood and can grow over time. If it breaks open, it can cause serious bleeding around the brain and requires emergency care.

Many aneurysms remain small and cause no problems, but some can become dangerous without warning.

Common causes and risk factors include:

• High blood pressure
• Smoking
• Heavy alcohol use
• Drug use (such as cocaine)
• Aging
• Family history of aneurysms
• Certain genetic or connective tissue conditions
• Hardening of the arteries

Symptoms

Cerebral aneurysms often develop silently. Some people may not notice any symptoms until the aneurysm leaks or ruptures.

Possible symptoms before rupture:

• Headaches
• Pain around or behind the eye
• Blurred or double vision
• Trouble moving the eye

Symptoms of a ruptured aneurysm (medical emergency):

• Sudden, severe headache
• Nausea or vomiting
• Stiff neck
• Sensitivity to light
• Confusion or difficulty staying awake
• Weakness or numbness
• Trouble speaking or walking
• Seizures

How is it diagnosed?

Doctors begin with a physical exam and a review of your symptoms and health history. Imaging tests are used to confirm the diagnosis and understand the size and location of the aneurysm.

Common tests include:

• CT scan to detect bleeding
• MRI to view brain tissue in detail
• CT or MR angiography to examine blood vessels
• Cerebral angiography for detailed vessel imaging

Some aneurysms are found unexpectedly during imaging for other conditions.

How is it treated?

Treatment depends on the size and location of the aneurysm, as well as your overall health.

Conservative care:

• Monitoring with regular imaging
• Managing blood pressure and lifestyle risks

Advanced treatment options:

• Endovascular coiling: A minimally invasive procedure that fills the aneurysm with tiny coils to block blood flow
• Surgical clipping: A procedure that places a clip at the base of the aneurysm to stop blood from entering it

The goal of treatment is to reduce the risk of rupture or prevent further bleeding.

Recovery varies depending on whether the aneurysm has ruptured and how quickly treatment is received.
