Symptom Checker: Symptoms & Signs Index
Medical Author: Melissa Conrad Stöppler, MD
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. When a brain aneurysm ruptures, there is bleeding within the brain. Symptoms of a ruptured brain aneurysm come on suddenly and include a severe, sudden headache that is different from other headaches an individual has experienced. Other symptoms of rupture are neck pain, sensitivity to light, nausea, vomiting, seizures, fainting, and loss of consciousness. A brain aneurysm is also known as a cerebral aneurysm or a cerebral artery aneurysm.
