Brain aneurysm is a bulging or balloon-like growth in humans, which appears typically in the areas where large arteries branch into smaller ones, generally observed at the base of the brain. Brain aneurysm is also known as cerebral aneurysm or intracranial aneurysm. Aneurysm has the potential to rupture, which causes bleeding in the surrounding subarachnoid space, generally resulting in brain damage or stroke.
Sometimes, it may lead to even death. Brain aneurysm rarely has any symptoms until the swelling ruptures. However, double vision, localized headache, and cranial nerve palsy are a few symptoms of mass effect of brain aneurysm on adjacent neurological structures. Key causes of brain aneurysm include heredity, aging, atherosclerosis infection, and brain injury.
