Brain Aneurysm Symptoms & Signs. A brain aneurysm is a bulging area within the wall of an artery that supplies the brain. In most cases, brain aneurysms do not produce symptoms. In some cases, the aneurysm may cause symptoms by pushing on other areas of the brain. Depending on the size of the aneurysm and the area involved, these symptoms can include headaches, neck pain, blurred vision, and speech changes.
The symptoms of an aneurysm vary with its type and location. It is important to know that aneurysms that occur in the body or brain generally do not present signs or symptoms until they rupture. However, those that occur near the surface of the body may show signs of swelling and pain. A large mass also may develop. The symptoms of ruptured aneurysms (anywhere in the body) include: 1  bleeding. 2  increased heart rate. 3  pain. 4  feeling dizzy or lightheaded.
