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.
In other cases, an unruptured aneurysm will cause problems by pressing on areas in the brain. When this happens, the person may suffer from severe headaches, blurred vision, changes in speech, and neck pain, depending on what areas of the brain are affected and how bad the aneurysm is.
