If one of the arteries in your brain develops a bulge, you may be diagnosed with a brain aneurysm. Brain aneurysms can exist for years without any warning signs until they leak, press on surrounding nerves or rupture. If the artery leaks or ruptures, it can be life-threatening if not treated properly. However, in some cases there may be symptoms that you have a brain aneurysm that is about to rupture.
Common Symptoms
The Brain Aneurysm Foundation states that you may experience changes in your vision, such as not being able to see out to the side, double vision, pain around the eyes and a localized headache before a brain aneurysm ruptures.
Additional Symptoms
According to the Mayo Clinic, "Most brain aneurysms, however, don't rupture, create health problems or cause symptoms." If they do cause symptoms, you may experience a loss of coordination, trouble maintaining balance, inability to concentrate, fatigue, sudden behavioral changes, speech difficulties and/or trouble with your short-term memory.
Severe Symptoms
The National Institute of Neurological Disorders and Stroke (NINDS) claims that if you have a brain aneurysm that is about to rupture or has become so large that it presses on surrounding nerves and tissue, you may notice more severe symptoms. These include a severe headache, nausea, vomiting, drooping eyelids, blurred vision, loss of sensation, sensitivity to light, and a painful or stiff neck. You may also experience numbness or paralysis on one side of you face, seizures and dilated pupils. You may even become unconscious or go into a coma.
