How to detect a Brain Aneurysm

It is a bulge or ballooning in a blood vessel in the brain, which often looks like a berry hanging on a stem.

A brain aneurysm can leak or rupture, causing bleeding into the brain (hemorrhagic stroke). Most often a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain and we call it a subarachnoid hemorrhagic stroke.

What are the effects of a brain aneurysm?

A brain aneurysm may not cause any symptoms unless it ruptures, but in some cases, it can show the following signs:

  • Visual disturbances
  • Pain above or around the eye
  • Numbness or weakness in the face
  • Difficulty speaking
  • Headaches
  • Balance problems
  • Difficulty concentrating
  • Problems with short-term memory

What causes brain aneurysms?

It’s not clear why a brain aneurysm forms. Researchers and neurosurgeons believe these factors irritate and weaken blood vessels:

How is a brain aneurysm diagnosed?

Your neurosurgeon will order a few imaging tests. These tests show the size, shape and location of brain aneurysms:

  • MRI (magnetic resonance imaging).
  • CT (computed tomography).
  • Diagnostic cerebral angiogram
  • MRA (magnetic resonance angiography).
  • CTA (computed tomography angiography).

How are brain aneurysms treated?

Surgery and/or endovascular therapy are the treatment for brain aneurysms, whether they are ruptured or unruptured.

A neurosurgeon treats brain aneurysms using a variety of methods, or a combination of methods, depending upon the type of aneurysm and the individual patient, which may include:
