What is a brain aneurysm?
A brain aneurysm is a weak spot in a blood vessel to the brain. A brain aneurysm most often has no symptoms, and people do not know they have it. Some brain aneurysms that have not ruptured cause symptoms, however a person may have a brain aneurysm his or her entire life that never causes a problem.
A brain aneurysm can leak or break open, sending blood into the skull. Blood goes into the space around the brain. When this happens patients generally have headache, loss of consciousness, or other symptoms.
Brain aneurysm warning signs
People usually have no symptoms of a brain aneurysm. But large aneurysms that have not ruptured can push on the brain or on nerves. This causes symptoms:
- Headache, especially sever headache
- Vision changes
- Seeing double
- Drooping eyelid or dilated pupil on one side
- Pain above or behind the eye
- Problems speaking
