“High blood pressure is one of the most important modifiable risk factors we see in patients with brain aneurysms. Managing blood pressure effectively can significantly reduce stress on fragile blood vessels and lower the risk of aneurysm growth or rupture.” - Dr. Manish Taneja
Cerebrospinal fluid (CSF) plays a vital role in protecting the brain, regulating pressure, and supporting neurological health. It surrounds the brain and spinal cord, helping cushion delicate structures and maintain stable pressure. In people with brain aneurysms, changes in CSF flow or pressure can influence symptoms, rupture risk, recovery, and long-term brain function. When CSF circulation, absorption, or pressure is disrupted - whether due to an aneurysm, bleeding, treatment, or aging - it can affect how the brain functions and how symptoms appear. This resource explores how CSF interacts with brain aneurysms - from diagnosis and treatment to aging, recovery, and symptom management - helping patients better understand changes that are often subtle, confusing, or overlooked.

Understanding Brain Aneurysm Symptoms, Risks, 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. Click on the sections below to learn more about early warning signs, symptoms in women, and signs of an unruptured and ruptured brain aneurysm.
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

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.

Put Brain Aneurysm on Your Health Radar
Did you experience the worst headache of your life? Could it be a brain aneurysm that ruptures, which means bleeding in the brain? Thoughts could be racing through your mind. Then what is the difference between unruptured (a weak or thin spot on an artery in the brain that balloons) or ruptured brain aneurysm? An unruptured brain aneurysm may cause subtle warning signs, such as pain or numbness on one side of the face, while symptoms of a ruptured brain aneurysm can include intense headache, loss of consciousness, and the leakage of blood into the cerebrospinal fluid when an aneurysm ruptures. If you’re wondering, then the Supreme Vascular and Interventional Clinic in Singapore is here to help. It’s important to look out for the tell-tale brain aneurysm symptoms, signs, causes, and risk factors.
At our specialized brain aneurysm clinic in Singapore, we help patients understand how conditions such as an arteriovenous malformation, high blood pressure, and weaknesses in the artery wall of a blood vessel or vessel in the brain can increase the risk of a brain aneurysm. Certain risk factors, including Ehlers-Danlos syndrome (EDS) and polycystic kidney disease (PKD), can further weaken blood vessels and raise the likelihood of rupture.
Dr. Manish Taneja has been performing brain aneurysm treatments offering personalized treatment options since 1995 from surgical clipping where the aneurysm is completely clipped to stop blood flowing into the weakened area, which prevents blood from re-entering the aneurysm sac and reduces the risk of future bleeding to latest minimally invasive procedures. Each patient is unique as is the size and location of the aneurysm. Your brain has different conditions to treat the aneurysm and artery vessel walls of a blood vessel in the brain. This calls for personalised brain aneurysm treatment depending on your symptoms, family, history, medication, and more. A simple CT scan could be just what the doctor ordered and the first step in early detection and prevention of a brain aneurysm.
