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.
Aneurysms develop slowly over many years and often have no symptoms. If an aneurysm expands quickly, tears open (ruptures), or blood leaks along the wall of the vessel (aortic dissection), symptoms may develop suddenly. Pain in the abdomen or back -- severe, sudden, persistent, or constant.
