A brain aneurysm is a balloon-like bulge in the wall of a brain artery. If this bulge tears and bleeds, nearby cells may be damaged. A brain aneurysm can occur in an artery wall that is weak or has a defect. Aneurysm is often associated with hardening of the arteries. High blood pressure, heredity, smoking, and a head injury are also risk factors.
In most cases, a brain aneurysm has no symptoms until it bleeds or tears. Symptoms of bleeding or tearing include:
Severe headache, nausea, and vomiting
Confusion or sluggishness
Vision or speech problems
Paralysis or weakness on one side of the body
A brain aneurysm needs to be treated as soon as possible. Doing so may save a patient’s life. If the aneurysm has torn and bled, treatment may not reverse the resulting damage. But surgery may help prevent more bleeding. Blood trapped in and around the brain may also be removed.
