Brain Aneurysm Causes and Risk Factors
Brain aneurysms can occur due to a combination of factors, hereditary predisposition, lifestyle choices, and certain medical conditions, all of which contribute to the development and potential rupture of an aneurysm.
What Are the Causes of a Brain Aneurysm?
Although the exact causes of a brain aneurysm aren’t always clear, several factors can contribute to the ballooning caused by the weakening of blood vessel walls. Those underlying causes include:
- High blood pressure or hypertension: High blood pressure significantly threatens the intricate blood vessels’ network in the brain, making it a potential risk factor for brain aneurysms.
- A family history of brain aneurysms: This may be a greater risk if a parent, grandparent, sister or brother has had a brain aneurysm.
- The age and gender of the patient: Those over 40 are at greater brain aneurysm risk and women have more brain aneurysms than men. Age-related vascular changes, cerebrospinal fluid balance, and chronic health conditions may also contribute to aneurysm vulnerability over time.
- Smoking and drug abuse: Studies have shown that cigarette smoking to be an important risk factor for brain aneurysm. Combined with drug abuse, this greatly increases the risk.
- Atherosclerosis (plaque buildup in the arteries): While atherosclerosis itself may not directly cause brain aneurysms, it can contribute to the overall risk profile of an individual by promoting high blood pressure and increasing hemodynamic stress. This altered blood flow pattern and increased stress on the arterial walls may raise the risk of brain aneurysm.
- In rare cases, head injury or infection of the blood vessel walls can be a cause of brain aneurysm. Even small aneurysms may require closer monitoring when additional risk factors such as smoking, hypertension, or family history are present.
Blood pressure, smoking, genetics, and vascular health all contribute to aneurysm stability and rupture risk. We provide care and treatments at our specialized brain aneurysm clinic at Supreme Vascular and Interventional Clinic in Singapore.
What are the Risk Factors of Getting a Brain Aneurysm?
While not fully understood yet, some of the known risk factors of cerebral aneurysm include:
Heredity: As mentioned above if you have a family history, the risk of brain aneurysm is higher. Certain inherited conditions such as polycystic kidney disease are associated with higher risk.
High blood pressure or hypertension: Here's why high blood pressure can be a potental high risk for brain aneurysms.
- Aneurysm formation: High blood pressure can contribute to the weakening of blood vessel walls, including those in the brain. The constant elevated pressure can cause the arterial walls to become thinner and less elastic over time, making them more prone to the formation of an aneurysm.
- Aneurysm rupture: Hypertension increases the stress on blood vessel walls, making them more vulnerable to rupture. If an aneurysm is present in the brain, high blood pressure can further increase the risk of its rupture. Ruptured brain aneurysms can lead to a potentially life-threatening condition called subarachnoid hemorrhage, which requires immediate medical attention.
- Blood flow and hemodynamic stress: Chronic high blood pressure can lead to altered blood flow patterns and increased hemodynamic stress in the blood vessels, including those supplying the brain. These changes in blood flow and stress can contribute to the development, growth, and rupture of brain aneurysms.
Cigarette Smoking: Smoking is considered a significant risk factor for the development and rupture of brain aneurysms. Studies have consistently shown a strong association between smoking and an increased risk of both the formation and rupture of aneurysms in the brain. Learn how smoking is one of the most well-established risk factors for brain aneurysms. Alcohol and caffeine may also influence vascular health.
Polycystic kidney disease: People with PCKD have a higher risk of developing brain aneurysms compared to the general population. Estimates suggest that the risk of having a brain aneurysm in individuals with PKD is approximately 4 to 8 times higher than in those without the condition. Read about the link between the two for for PCKD patients with brain aneurysms.
Risk Factors You Can Change:
Fortunately, two significant risk factors that can be controlled are smoking and high blood pressure. High blood pressure can increase the risk of developing a brain aneurysm, which is a potentially life-threatening condition involving the weakening and bulging of a blood vessel in the brain. In some individuals, regular screening may be recommended. This guide explains who may benefit from screening in Singapore, what the process involves, and how to decide if it is the right step based on your personal risk.

Brain Aneurysm and High Blood Pressure: Knowing the Link
Imagine a ticking time bomb lurking inside your brain, silently waiting to unleash its devastating power. This hidden danger is known as a brain aneurysm, a potentially life-threatening condition that demands our attention. Below is the intricate relationship between brain aneurysms and high blood pressure as explained by brain aneurysm specialist, Dr. Manish Taneja.
What Are the Causes of a Brain Aneurysm?
Before examining the relationship between brain aneurysm and high blood pressure, there are more underlying causes. Although the exact causes of a brain aneurysm aren’t always clear, several factors can contribute to the ballooning caused by the weakening of blood vessel walls. These include:
- high blood pressure, or hypertension
- a family history of brain aneurysms
- the age and gender of the patient
- smoking and drug abuse
- atherosclerosis—plaque buildup in the arteries
- in rare cases, head injury or infection of the blood vessel walls
What is Blood Pressure?
Blood pressure is the exerted force by circulating blood against the blood vessel walls, measured in millimeters of mercury (mmHg). It is represented by two values, namely:
- Systolic pressure (the higher value)
- Diastolic pressure (the lower value)
Blood Pressure and Your Brain
Your brain, the control center of your body, relies on a constant oxygen-rich blood supply to function optimally. Any disruption in this delicate balance can have severe consequences. High blood pressure significantly threatens the intricate blood vessels' network in the brain, making it a potential risk factor for brain aneurysms.
BP as a Risk for Brain Aneurysm
When it comes to brain aneurysms, high blood pressure, also known as hypertension, is considered a significant risk factor. Hypertension can diminish the walls of blood vessels over time, making them more prone to developing aneurysms. In that case, patients with high blood pressure to manage it effectively to reduce the risk of developing brain aneurysms.
It is also important to establish blood pressure goals specifically for individuals at risk of brain aneurysms. Maintaining optimal blood pressure levels can significantly reduce the risk of aneurysm formation and rupture. Work with our neurointervention specialist, Dr. Manish Taneja to develop a plan to lower blood pressure.
Increased Risk with High Blood Pressure
Numerous studies have shown that individuals with high blood pressure are at a higher risk of developing brain aneurysms compared to those with normal blood pressure. Additionally, high blood pressure can increase the chances of an aneurysm rupturing, leading to potentially fatal consequences such as stroke and brain damage.
At our brain aneurysm clinic, our mission is to deliver the highest standard of care with Dr. Manish Taneja's compassionate approach every step of the way for your brain well-being, diagnosis, and treatment.
