Brain Aneurysm Symptoms

Symptoms that Indicate the Presence of a Brain Aneurysm.

A brain aneurysm is described as a ballooning of a blood vessel, which is an artery, vein, or capillary. As the blood vessel continues to weaken, the balloon continues to grow and as a result, poses a risk that it may rupture or burst. A person with a small cerebral aneurysm usually shows no sign of having one. But once it grows and becomes large, it may apply pressure on to the surrounding nerves and tissues, which may cause double vision, dilated pupils, pain above and below the eye, paralysis or numbness on one side of the patient’s face, nausea, stiff necks, and mild to severe headaches.

True cause of brain aneurysms

The true cause of brain aneurysms are not yet determined, but somehow their occurrence is related to the absence of a muscular layer which is part of the blood vessels that thins over time. Because of this absence, the blood vessels thin out more rapidly, leading to a rupture. Statistics say that about 3% to 5% of Americans have brain aneurysms.
