What is a Brain Aneurysm and How Does It Form?
A brain aneurysm is a bulge in a weakened area of a blood vessel within the brain. It forms when the blood flowing through the vessel puts pressure on the vessel wall, which then can burst, causing bleeding. While most brain aneurysms never rupture and do not cause symptoms, a ruptured brain aneurysm is considered life-threatening. This article is part of our guide to brain aneurysm symptoms. For a complete overview, visit, Brain Aneurysm Symptoms: A Detailed Guide to Early Signs and Warning Symptoms.
Types of Brain Aneurysms
The main types of brain aneurysms are:
- Saccular aneurysm - a small bulge formed on a weakened area of a blood vessel in the brain and resembling a berry hanging from a branch.
- Fusiform Aneurysm - this aneurysm bulges from all sides of an artery. Elongated with a spindle-shaped appearance, the fusiform aneurysm extends along a blood vessel and causes a uniform dilation.
- Mycotic Aneurysm - a rare type of aneurysm, this is caused by an infected artery wall.
- Giant Aneurysm - this type of aneurysm typically involves more than one artery and can be over 2.5 centimeters wide.
Risk Factors and Complications Associated With Brain Aneurysms
Risk factors for brain aneurysms include smoking, aging, high blood pressure, and family history. Other risk factors include:
- Substance use
- Genetic conditions such as such as polycystic kidney disease, Ehlers-Danlos syndrome, and Marfan's syndrome
- Trauma to the head or brain
- Atherosclerosis, or a buildup of plaque in the arteries.
Brain aneurysms can be associated with serious complications including hemorrhagic stroke, brain damage, coma, and in the most severe cases, death.
Overview of Alzheimer's Disease
As the most common form of dementia. Early symptoms of Alzheimer's Disease include confusion, restlessness, hallucinations, delusions, and forgetting recent conversations and events. Over time, Alzheimer's progresses and symptoms become more severe. In the final stages, patients may be unable to talk or know what is going on around them. Genetic factors, health, lifestyle, head injuries, infections, vascular diseases, and age-related changes in the brain are all causes of Alzheimer's Disease.
Neurological Changes That Occur in Alzheimer's Patients
Progressive degeneration and death of the brain cells are the primary neurological changes that occur in patients. This happens in areas of the brain responsible for memory and cognitive function, which then cause significant brain shrinkage. As a result, cognitive abilities such as memory, language, social behavior, and reasoning are negatively impacted.
Current Statistics on Alzheimer's Disease
It is estimated that over 55 million people worldwide are living with Alzheimer's, and this number is expected to rise to over 139 million by 2030.
Potential Link Between Brain Aneurysms and Alzheimer's Disease
Brain aneurysm survivors may have an increased risk of developing Alzheimer's, with some studies suggesting that survivors of ruptured intracranial aneurysms may experience varying degrees of cognitive decline. When aneurysms are detected early, they can be treated to reduce the risk of rupturing and serious cardiovascular complications.
Shared risk factors for brain aneurysms and Alzheimer's include:
- Hypertension
- Age
- Lifestyle Factors
Impact of Brain Aneurysms on Cognitive Function
When aneurysms rupture and result in brain injury, it can cause impairments in memory, attention, language processing, and information processing speed. A chronic aneurysm can put pressure on the surrounding brain tissue, disrupting blood circulation and resulting in headaches, vision problems, and neurological deficits.
Brain Aneurysm Diagnosis and Monitoring
Early detection of both brain aneurysms and Alzheimer's disease is vital to delay the possible onset of dementia and give the patient a better chance of benefiting from treatment. Diagnostic tools such as CT scans and MRIs are used for the diagnosis of brain aneurysms, while cognitive assessments are used for Alzheimer's.
Monitoring is key, and patients who are at high risk for brain aneurysms should have a first follow-up at 6-12 months after the initial discovery and annually after that. Those at risk of Alzheimer's should have regular cognitive assessments like the MMSE at routine checkups to track changes in memory, language, reasoning, and orientation over time.
Brain Aneurysm Management and Treatment
Observation for brain aneurysms is usually done for managing those that are small with a low risk of rupture. Regular imaging tests should also be performed. Everyone should keep in mind that each aneurysm is unique, and treatment depends on the size, location, and whether it has ruptured. Brain aneurysm treatment options include:
- Surgical Clipping
- Endovascular Coiling
- Flow Diverters
It is important to remember that brain aneurysms and Alzheimer's disease are both brain conditions that can increase the risk of dementia. Ruptured aneurysms can lead to vascular risk factors, such as stroke, hypertension, and diabetes, which can directly contribute to Alzheimer's disease.

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.

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.

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

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:
A simple (computed tomography) CT scan could be just what the doctor ordered and the first step in early detection and prevention of a brain aneurysm. Come in for an easy consultation with our brain aneurysm specialist in Singapore to be on your health radar.
