How do I know if I have an unruptured aneurysm?

Could You Have an Unruptured Brain Aneurysm Without Knowing?

Many people live with an unruptured brain aneurysm and never know it. In fact, most small aneurysms cause no symptoms at all and are often discovered by chance during imaging for unrelated conditions. However, when an aneurysm grows larger, it can begin to press on surrounding brain tissue or nerves, leading to noticeable warning signs.

Symptoms to watch for include persistent pain above and behind one eye, blurred or double vision, a drooping eyelid, or even facial numbness. These occur because of pressure on the nerves responsible for eye movement and sensation. Some people may also experience headaches that feel different from their usual pattern—often localized and unrelenting.

It’s important to stress that these symptoms don’t automatically mean you have an aneurysm; they can be linked to other, less serious conditions. But if they’re new, persistent, or worsening, it’s worth discussing with a doctor. Risk factors like a family history of aneurysms, high blood pressure, smoking, or certain genetic conditions can increase your likelihood and may warrant closer monitoring.

Diagnosis usually involves imaging such as an MRI or CT angiogram, which can visualize blood vessels in the brain. While the idea of an aneurysm can be frightening, many go untreated if they remain small and stable. When needed, preventive treatment—like surgical clipping or endovascular coiling—can reduce the risk of rupture.

The bottom line? Listen to your body. Unruptured doesn’t mean unnoticed, and early detection can be life-saving. If something feels off neurologically, especially with risk factors in play, don’t wait—seek evaluation.
