Signs & Symptoms of an Aneurysm in Your Brain
When the walls of an artery in the brain deteriorate or become too thin, a portion of the weakened blood vessel might begin to protrude outward. This potentially life-threatening deformity is called a brain aneurysm.

Ruptured Aneurysm
-
Brain aneurysms that rupture or cause a break in the arterial wall demand immediate medical attention. Symptoms include an extremely painful and sudden headache, confusion, impaired vision, nausea, seizure and vomiting.
Ruptured Aneurysm Complications
-
Ruptured brain aneurysms typically bleed for several seconds, but they can cause lost consciousness or death if too much pressure builds up and restricts the flow of blood and oxygen to the brain.
-
Unruptured Aneurysm
-
Brain aneurysms that don't rupture sometimes have no symptoms. Larger unruptured aneurysms might exert pressure on nearby nerves and brain tissue, causing a dilated pupil, a droopy eyelid, faulty vision, eye pain, and unilateral facial numbness, paralysis or weakness.
Leaking Aneurysm
-
Leaking brain aneurysms discharge a small amount of blood through a break. Such sentinel bleeds usually only produce acute headaches, often followed by a more serious rupture.
Risk Factors
-
Factors that might help weaken the walls of brain arteries and increase the risk of an aneurysm include drinking excessive alcohol, drug abuse, head injuries, high blood pressure, smoking and relatives with an aneurysm.
