An aneurysm is a serious medical condition that can have life-threatening consequences if not caught in time. This occurs when a blood vessel in the brain bulges or balloons due to a weak arterial wall. While many aneurysms remain asymptomatic and harmless, a ruptured aneurysm can lead to a type of stroke known as a hemorrhagic stroke, which can be fatal. Knowing the warning signs and seeking immediate medical attention can make the difference between life and death. In this article, we’ll discuss the 12 key signs of an aneurysm that should never be ignored.
What Is an Aneurysm?
Before diving into the symptoms, it’s important to understand what an aneurysm is. An aneurysm is a bulge or ballooning in a blood vessel caused by weakness in the vessel wall. While the majority of aneurysms don’t rupture, when they do, they can cause severe health complications including brain damage, stroke, and even death. Early detection and treatment are key in preventing the worst outcomes.
1. Sudden Intense Headache: The Worst of Your Life
A sudden, severe headache that comes on unexpectedly is one of the most common signs of a brain aneurysm rupture. People often describe it as “the worst headache of my life.” This intense pain is caused by bleeding in the brain and can happen without warning. If you experience this kind of headache, it’s crucial to seek emergency medical attention immediately.
2. Blurred or Double Vision
Vision changes such as blurred or double vision are also warning signs of a potential brain aneurysm. Aneurysms can put pressure on the optic nerve, affecting your vision. If you start noticing issues with your sight, don’t ignore it. Blurred or double vision accompanied by other symptoms should prompt you to seek medical advice immediately.
3. Confusion or Disorientation
Brain aneurysms can cause confusion or a sudden feeling of disorientation. If you or someone around you suddenly feels lost or unsure of what’s happening, it could be a result of bleeding in the brain. This symptom may occur alongside other severe symptoms, making it even more critical to act fast.

4. Uneven Pupil Size
If one of your pupils becomes noticeably larger than the other, it could indicate that an aneurysm has affected the brain. Uneven pupil size is a common symptom of increased pressure in the brain and is often seen in people who have experienced a brain aneurysm rupture.
5. Drooping Eyelid (One Side)
A drooping eyelid on one side can be a sign that the brain is being affected by an aneurysm. This symptom typically occurs when the aneurysm puts pressure on the nerves controlling the eye muscles. If accompanied by other symptoms like vision changes or headache, seek immediate medical attention.
6. Sudden Fainting or Loss of Consciousness
Aneurysm ruptures can cause sudden fainting or a loss of consciousness. This happens when there is a drastic change in blood flow to the brain. If you or someone around you loses consciousness without explanation, it could be an emergency related to a brain aneurysm.
7. Nausea and Vomiting
Sudden nausea or vomiting, especially when accompanied by a headache or blurred vision, may be a sign of a ruptured aneurysm. The increased pressure in the brain caused by bleeding can trigger nausea, making this an important symptom to watch for.
8. Pain Behind or Around One Eye
A brain aneurysm can cause sharp, localized pain behind or around one eye. This is typically due to the pressure that the aneurysm exerts on nearby nerves. If you experience this type of pain along with other symptoms like vision changes or a severe headache, don’t hesitate to seek immediate medical care.
9. Stiff Neck
A stiff neck is another symptom that can be caused by a brain aneurysm. The pain is usually more intense when trying to move the neck, and it may be accompanied by a headache. If your neck pain is severe and doesn’t improve, it’s essential to get checked out by a healthcare provider.
10. Sensitivity to Light
Light sensitivity, or photophobia, is another common symptom seen in those with an aneurysm. This is often coupled with headaches or blurred vision. If you find yourself increasingly sensitive to light, combined with any of the other symptoms listed, it’s time to seek immediate medical care.
11. Seizures
Seizures can occur when an aneurysm ruptures, as the bleeding in the brain disrupts normal electrical activity. If you or someone else experiences a seizure along with any of the above symptoms, don’t wait—seek emergency medical help immediately.
12. Sudden Weakness or Numbness
Weakness or numbness in the arms, legs, or face—especially if it is on one side of the body—can be a sign of an aneurysm rupture. This can happen when blood flow to the brain is disrupted by the aneurysm. Any sudden numbness or weakness that is unexplained should be treated as an emergency.
What Is a “Leaking” Aneurysm?
A “leaking” aneurysm refers to a small amount of blood leaking out of the aneurysm before it fully ruptures. This is known as a sentinel bleed and may cause a sudden, sharp headache that can last for a few days or weeks. If you experience persistent, unexplained headaches, it’s important to seek medical attention to avoid the risk of a full rupture.

Who Is at Risk for Brain Aneurysms?
While anyone can experience a brain aneurysm, certain factors can increase your risk. These include:
- Family history: If someone in your family has had an aneurysm, your chances of developing one increase.
- Age: Brain aneurysms are more common in people over 40, especially in women.
- High blood pressure (hypertension): This can strain the blood vessels and increase the risk of aneurysm formation.
- Smoking and drug use: Smoking and certain drugs like cocaine weaken blood vessels, increasing the risk of aneurysms.
Prevention and Early Detection
While not all aneurysms can be prevented, there are steps you can take to lower your risk. These include managing high blood pressure, quitting smoking, reducing alcohol consumption, and maintaining a healthy lifestyle. Regular check-ups, especially if you are at higher risk, can help detect aneurysms early and prevent ruptures.
Conclusion: Don’t Ignore the Signs of an Aneurysm
Early detection of a brain aneurysm can save lives. By recognizing the warning signs of a ruptured or unruptured aneurysm, you can take immediate action to protect your health. If you or someone around you experiences any of the symptoms listed above, seek emergency medical attention immediately. Time is critical, and early intervention is key to a positive outcome. Always listen to your body and don’t ignore unusual or extreme symptoms—your health is worth it.
