To rule out brain aneurysms, doctors use advanced imaging like CT Angiography (CTA), MR Angiography (MRA), or the definitive Cerebral Angiogram, which highlight blood vessels to find abnormalities, often after a CT scan shows initial signs of bleeding. A spinal tap (lumbar puncture) can check cerebrospinal fluid for blood, while non-contrast CTs quickly detect acute bleeding, making these tests effective at ruling out or confirming aneurysms.

How do they check for brain aneurysms?

A CT angiogram can create detailed images of the arteries providing blood flow in the brain. The test involves injecting dye into the vein that makes it easier to observe blood flow. It also can detect the presence of an aneurysm.

What were your first signs of a brain aneurysm?

The first signs of a brain aneurysm depend on whether it's unruptured or ruptured; unruptured ones often have no symptoms but can cause pain behind the eye, vision changes, or a dilated pupil if large, while a ruptured one causes a sudden, severe "thunderclap headache," nausea, stiff neck, confusion, or seizures, requiring immediate emergency care. Some people experience warning signs (sentinel headaches) days or weeks before a major rupture.

What is the gold standard test for brain aneurysm?

Angiogram: For a traditional angiogram, doctors insert a catheter (a thin tube) into your body to see your blood vessels more clearly. It's the gold standard for diagnosing brain aneurysms because it gives a 3-D view of an aneurysm, offering precise details that help determine the best treatment for you.

What are the silent symptoms of aneurysms?

Silent symptoms of an unruptured brain aneurysm often involve subtle signs from pressure on nerves: pain above/behind one eye, a dilated pupil, drooping eyelid, facial numbness/weakness on one side, vision changes (double vision), or mild chronic headaches; these usually occur as the aneurysm grows, while a sudden, severe headache signals a dangerous rupture.

What triggers a brain aneurysm?

Brain aneurysms are caused by weakened artery walls, often forming at weak points like artery forks, with risk factors including high blood pressure, smoking, drug use (cocaine), family history, age (30-60), and being female, plus potential links to certain disorders, infections, or head trauma. These factors weaken the vessel, leading to a bulge that can rupture, though many form silently over time from wear and tear.

How long can you have a brain aneurysm before it bursts?

Sometimes, an aneurysm leaks a small amount of blood into the brain, called a sentinel bleed. Sentinel or warning headaches can occur days or weeks before a major rupture, when an aneurysm has a small leak. But only a small number of people have a sentinel headache before a rupture.

Can stress cause brain aneurysms?

No, stress doesn't directly cause a brain aneurysm to form, but chronic stress can significantly raise your blood pressure and trigger unhealthy coping habits (like smoking), both major risk factors that can contribute to an aneurysm developing or cause an existing one to rupture. Stress-induced spikes in blood pressure put extra strain on weak artery walls, increasing the risk of rupture, according to ColumbiaDoctors, Nuvance Health, Shore Physicians Group, and my.clevelandclinic.org.
