How to Recognize the Signs of an Unruptured Aneurysm

Most unruptured brain aneurysms are silent—many people live with them without ever knowing. Often, they’re discovered only during imaging for unrelated conditions. But when symptoms do appear, they can be subtle and easily mistaken for other issues. Recognizing the early warning signs could make a critical difference.

One of the more telling signs is persistent pain above or behind one eye. This isn’t your typical headache—it’s localized and often accompanied by neurological changes. A dilated pupil in one eye, especially when paired with drooping eyelids or difficulty focusing, may point to pressure on the nerves near the aneurysm.

Changes in vision—like blurriness, double vision, or even partial vision loss—are also red flags. Since an aneurysm can press on the optic nerve or surrounding brain tissue, visual disturbances are more common than many realize. Similarly, numbness on one side of the face can signal nerve compression caused by the bulging vessel.

In some cases, an unruptured aneurysm can trigger seizures, particularly if it irritates brain tissue. While seizures have many potential causes, unexplained episodes should prompt further neurological evaluation.

It’s important to note that not everyone with these symptoms has an aneurysm, but if the signs are new, persistent, or worsening, seeing a doctor is essential. Early detection through imaging like MRI or CT angiography allows for monitoring or treatment before rupture occurs—a scenario that can be life-threatening.

If you or someone you know is experiencing unexplained eye pain, vision changes, or facial numbness, don’t dismiss it. While an unruptured aneurysm may not always demand immediate surgery, understanding the risks and staying vigilant could save a life.
