Unruptured brain aneurysms are typically completely asymptomatic. These aneurysms are typically small in size, usually less than one half inch in diameter. However, large unruptured aneurysms can occasionally press on the brain or the nerves stemming out of the brain and may result in various neurological symptoms. Any individual experiencing some or all of the following symptoms, regardless of age, should undergo immediate and careful evaluation by a physician.

• Localized Headache
• Dilated pupils
• Blurred or double vision
• Pain above and behind eye
• Weakness and numbness
• Difficulty speaking

Ruptured brain aneurysms usually result in a subarachnoid hemorrhage (SAH), which is defined as bleeding into the subarachnoid space. When blood escapes into the space around the brain, it can cause sudden symptoms.

Seek Medical Attention Immediately If You Are Experiencing Some Or All Of These Symptoms:

• Sudden severe headache, the worst headache of your life
• Loss of consciousness
• Nausea/Vomiting
• Stiff Neck
• Sudden blurred or double vision
• Sudden pain above/behind the eye or difficulty seeing
