Unruptured brain aneurysms are typically completely asymptomatic. These aneurysms are typically small in size, usually less than 5mm 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.

Sudden severe headache, the worst headache of your life

Sudden blurred or double vision
