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.
1. Headaches. In the case of a brain aneurysm, headaches can become a frequent complaint. While un-ruptured brain aneurysms usually remain quite small, larger ones can press on the brain or nerves stemming out of the brain. This can trigger localized headaches and other related symptoms.
