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.

Depending on the size of the aneurysm and the area involved, these symptoms can include headaches, neck pain, blurred vision, and speech changes.
If an aneurysm expands rapidly, tears, or leaks, the following symptoms may develop suddenly: 1  intense and persistent abdominal or back pain that may radiate to the buttocks and legs. 2  sweating and clamminess. 3  dizziness. 4  nausea and vomiting. 5  rapid heart rate. 6  shortness of breath. 7  low blood pressure.
