About brain aneurysms
What is Brain Aneurysm
A brain aneurysm is a bulge or ballooning in an artery in the brain caused by weakness in the blood vessel wall. A brain aneurysm can leak or rupture, causing bleeding into the brain (hemorrhagic stroke).
Brain aneurysms are more common than all of us may think. An estimated 1 in 50 people has a brain aneurysm. Although it is slightly more common in women than men, and particularly those who are in their late 40s to mid-50s. Really it may occur at any age.
Ruptured aneurysms become life-threatening and require timely medical treatment. Most brain aneurysms, even though they do not rupture, create health problems, or cause symptoms.
In some cases, the treatment for an unruptured brain aneurysm may be appropriate and prevent a rupture in the future.
Brain Aneurysm Symptoms
Symptoms of unruptured aneurysm include (not only):
An unruptured brain aneurysm could produce no symptoms, particularly if it is small. However, a larger unruptured aneurysm might press on brain tissues and nerves, possibly producing:
Unexpected and hugely severe headache
Blurred or double vision
Pain above or behind the eye
Weakness / numbness on one side of the face
If it is not treated, a brain aneurysm can continue to expand and ultimately rupture.
