While most unruptured brain aneurysms are small and do not produce symptoms, large unruptured aneurysms can result in neurological complications, such as difficulty speaking, localized headaches, vision disturbances, dilated pupils and numbness, explains Brain Aneurysm Foundation. A ruptured aneurysm often produces a severe headache, nausea, vomiting or loss of consciousness.Continue Reading
The neurological symptoms associated with large unruptured aneurysms result from the aneurysm placing pressure on the brain or the nearby nerves, notes Brain Aneurysm Foundation. Weakness and pain behind or above the eye are other neurological symptoms that can arise. Most people with brain aneurysms are between the ages of 35 and 60, but they can occur at any age.
A ruptured aneurysm usually produces a hemorrhage into the subarachnoid space around the brain and constitutes a medical emergency, warns Brain Aneurysm Foundation. The headache that follows a ruptured brain aneurysm is often described as the worst headache the individual has ever experienced. Other common indicators of a ruptured aneurysm include seizures, sudden light sensitivity, drooping eyelids, changes in mental state and a stick neck. Difficulty walking, double or blurred vision that arises suddenly, and sudden-onset numbness may also occur, warranting immediate medical attention. Approximately 40 percent of ruptured brain aneurysms result in death, while about 66 percent of people who survive a rupture have permanent neurological issues as a result.Learn more about Conditions & Diseases
