Patients with “giant” aneurysms (1 inch or greater in diameter) have a much higher risk of rupture. The survival rate for those with a ruptured brain aneurysm is about 60% (40% die). For those who survive and recover, about 66% have some permanent neurological defect.What are the long term effects of a brain aneurysm?
Difficulty in Speaking: Another long-term effect of a brain aneurysm is difficulty in speaking. Although it is common, the level of difficulty depends on the location of the rupture occurred in the brain. Additionally, the rupture can also pose a problem in swallowing.Are there any warning signs of a brain aneurysm?
Other early warning signs of a brain aneurysm include blurred vision and photophobia or light sensitivity, notes the Brain Aneurysm Foundation.

Causes and symptoms. Cerebral aneurysms can be caused by brain trauma, infection, hardening of the arteries (athero-sclerosis), or abnormal rapid cell growth (neoplastic disease), but most seem to arise from a congenital, or developmental, defect. These congenital aneurysms occur more frequently in women.
