In some cases, an unruptured aneurysm may cause changes in speech, along with neck pain, blurred vision and severe headaches, as it presses on specific areas of the brain, as reported by eMedicineHealth. However, most brain aneurysms present no symptoms and can easily go unnoticed before they rupture. The symptoms of a brain aneurysm usually occurs suddenly and may include seizure, sensitivity to light, stiff neck, nausea and vomiting, blurred or double vision and an extremely severe headache.
A ruptured brain aneurysm requires immediate medical attention because it quickly becomes life threatening. The result of a subarachnoid hemorrhage is either death or brain damage, depending on its severity, according to WebMD. The tendency to form aneurysms can be genetically inherited. Other risk factors that may cause aneurysms include aging, atherosclerosis, or hardening of the arteries, excessive alcohol consumption, head injury, high blood pressure and smoking. Some risk factors are controllable while others are not. Brain aneurysms are more rampant among women than men, and they are more likely to develop in adults than children.
A surgical clipping or embolization surgery may be performed to treat an unruptured aneurysm. The type of treatment administered typically depends on the age and health of the patient and the size of the aneurysm.
