BRAIN ANEURYSM SYMPTOMS AND WARNING SIGNS
This page is part of our Brain Aneurysm Resources hub and falls under our Brain Aneurysm Symptoms and Warnings Signs page. It is designed for patients and families seeking clear, reliable, and easy-to-understand information about how brain aneurysms may present, before and after rupture, and why early recognition matters.
Consult Brain Aneurysm Specialist, Dr. Manish Taneja
Brain aneurysm treatment calls for advanced technology and an experienced doctor. The Supreme Vascular and Interventional Clinic in Singapore is a regional destination for high-quality and compassionate care. Go beyond the basics of the meaning of a brain aneurysm condition, the causes, symptoms, signs, and more.
“Brain aneurysm symptoms are not always dramatic. Many patients experience subtle neurological changes long before rupture. Recognizing these early signs allows us to intervene before serious complications occur.” - Dr. Manish Taneja
Brain aneurysms may cause different symptoms depending on their size, location, and whether bleeding has occurred. While many aneurysms remain silent and are discovered incidentally during imaging, others may produce neurological symptoms ranging from headaches and vision changes to sudden medical emergencies requiring urgent care. Understanding possible warning signs may help patients seek timely medical evaluation and better understand when imaging or specialist assessment may be necessary.

🔹 Reducing Risks Series: Preventing Brain Aneurysms
Focuses on modifiable risk factors and proactive steps patients can take to protect brain health.
Reducing Risk and Prevention
The most effective way on how to prevent brain aneurysm is to reduce the risk of a brain aneurysm is to manage controllable risk factors and maintain long-term vascular health. While not all aneurysms can be prevented, controlling blood pressure, avoiding smoking, and addressing underlying medical conditions can significantly lower the risk of aneurysm formation and rupture. To better protect your brain health, understanding symptoms is just as important as prevention.

Early Symptoms of a Brain Aneurysm
Brain aneurysms can be life-threatening, and early recognition of warning signs is crucial. Not all symptoms appear at once, and some may be subtle, but knowing what to look for can save lives.
Here are some possible early symptoms of an unruptured brain aneurysm and some individuals with an unruptured aneurysm may experience one or more of the following:
- Persistent or unusual headaches, especially those that feel different from your usual headache pattern
- Pain behind or around one eye
- Visual changes, including blurred vision, double vision, or difficulty focusing
- Facial numbness, tingling, or weakness
- Neck pain or stiffness
- Dizziness or balance problems
- Difficulty concentrating or subtle cognitive changes
- A general sense that something feels neurologically “off”
These symptoms do not mean that an aneurysm is about to rupture, and most people with these complaints do not have a brain aneurysm. However, new, unexplained, or progressively worsening neurological symptoms should always be assessed, particularly when they do not respond to usual treatments.
We’ve also compiled a collection of resources to help you understand the most common symptoms, risk factors, and considerations for different populations, empowering you to take timely action.

Unruptured Brain Aneurysm Symptoms
Unruptured Brain Aneurysm Symptoms Include:
- Numbness or weakness on one side of the face
- A drooping eyelid
- Headache
- Blurred or double vision
- Dilated pupil of one eye
- Pain behind and above one eye
Find out more here about the silent but not harmless unruptured brain aneurysm symptoms.
Ruptured Brain Aneurysm Symptoms
Ruptured Brain Aneurysm Symptoms Include:
- As in an unruptured brain aneurysm, blurred or double vision
- A severe, sudden headache, which patients often
- describe as the “worst headache of their life”
- Nausea and/or vomiting
- Stiffness in the neck
- Extreme sensitivity to light
- Seizures
- Loss of consciousness
- Altered mental state or confusion
Note: If you believe someone displays symptoms of a ruptured brain aneurysm, you must seek medical assistance immediately. Timely diagnosis and treatment can improve the chances of survival and reduce severe complications due to a debilitating stroke, for example. Read more here about early and progressive ruptured brain aneurysm symptoms.
Brain Aneurysm Symptoms in Women
While there are no symptoms that occur only in women and not in men when it comes to brain aneurysms, women are approximately 2–3 times more likely than men to have an intracranial (brain) aneurysm. The difference becomes more pronounced after age 50, particularly post-menopause. Women also have a slightly higher lifetime risk of rupture.
Symptoms are determined by:
- Whether the aneurysm is ruptured or unruptured
- Its size and location
- Whether it is pressing on nearby nerves or brain tissue
Read how females have a higher risk and what are the key differences between men and women when it comes to brain aneurysms.

Take the Next Step Toward Protecting Your Brain Health
Brain aneurysm symptoms are not always dramatic, but they are rarely random. Persistent, progressive, or unexplained neurological changes deserve careful evaluation. Early recognition allows for monitoring, risk reduction, and timely treatment before rupture occurs. If you are experiencing new or unexplained neurological symptoms, or if you have known risk factors for brain aneurysms, a specialist consultation can provide clarity and reassurance. Dr. Manish Taneja, at our specialized brain aneurysm clinic in Singapore, the Supreme Vascular and Interventional Clinic, offers comprehensive evaluation using advanced imaging and personalized care planning. Early assessment may help detect aneurysms before complications arise and guide safer, more confident decision-making.
Suffering from an intense headache is not only painful, but it can also be dangerous. Either a brain aneurysm or a stroke could be the cause. And either could be fatal. As such there can be confusion or overlap between the two. Simply put, a brain aneurysm is a form of stroke and ruptured brain aneurysm is one of the causes of stroke, although less common.

Put Brain Aneurysm on Your Health Radar
Did you experience the worst headache of your life? Thoughts could be racing through your mind. A brain aneurysm is a weak spot in a blood vessel in the brain that can change over time. The key concern is when an aneurysm ruptures, which can disrupt blood flow, affect brain tissue, and lead to serious brain damage. Controllable conditions like high blood pressure can increase this risk and treatment options can depend on the condition. Surgical clipping is one option that prevents blood from entering the weakened area. In many cases, minimally invasive treatments can also be used to restore normal blood flow and reduce risk. We have created structured guides to help you explore each stage in more detail:
