Researchers think high blood pressure is the most common cause of a rupture. Higher blood pressure makes blood push harder against blood vessel walls. Situations that can increase blood pressure and lead to a brain aneurysm rupture include: Ongoing stress or a sudden burst of anger or other strong emotion.
Causes of aneurysms
high blood pressure (hypertension) over many years resulting in damage and weakening of blood vessels. fatty plaques (atherosclerosis) resulting in a weakness of the blood vessel wall. inherited diseases that may result in weaker than normal blood vessel walls.
Experts think brain aneurysms form and grow because blood flowing through the blood vessel puts pressure on a weak area of the vessel wall. This can increase the size of the brain aneurysm. If the brain aneurysm leaks or ruptures, it causes bleeding in the brain, known as a hemorrhagic stroke.
An unruptured aneurysm might not initially have any symptoms, but that usually changes as it grows larger. The warning signs that indicate a person has developed an unruptured brain aneurysm include: Pain behind or above an eye. Double vision.

High blood pressure, which is the leading risk factor for thoracic aortic aneurysms but also a risk factor for abdominal aortic aneurysm. Bacterial infections, which are a risk factor for thoracic aortic aneurysms. Kidney conditions, such as renal failure, chronic kidney disease, and polycystic kidney disease. Obesity.
Symptoms of a ruptured brain aneurysm usually begin with a sudden agonising headache. It's been likened to being hit on the head, resulting in a blinding pain unlike anything experienced before. Other symptoms of a ruptured brain aneurysm also tend to come on suddenly and may include: feeling or being sick.
Can people live a long time with a brain aneurysm? Absolutely. Many aneurysms cause no symptoms at all. Some people live for years without knowing they have a brain aneurysm.
Sleep deprivation can weaken your immune system. Now, a new clinical study suggests that insomnia may be a potential risk factor for a brain bleed from a ruptured aneurysm. “Ruptured aneurysms are highly fatal.
The best way to prevent getting an aneurysm, or reduce the risk of an aneurysm growing bigger and possibly rupturing, is to avoid activities that could damage your blood vessels. Things to avoid include: smoking. eating a high-fat diet.
Opt for low-fat or fat-free dairy in lieu of full-fat dairy. Reach for whole grains and complex carbohydrates, such as brown rice or whole-grain bread, rather than refined, white carbohydrates, like white rice or white bread. Avoid or limit sugar-sweetened beverages, including soda, fruit juice, and energy drinks.
Doctors often describe the head pain caused by a burst aneurysm as a "thunderclap." The pain comes on in an instant, and it's very intense. It will feel like the worst headache of your life. A migraine, on the other hand, tends to come on gradually.
Inherited risks associated with brain aneurysms
A family history of aneurysms can suggest a higher chance of having the condition. But, these risks increase even more if you have two or more first-degree relatives — such as a parent, sibling, or child — who have an aneurysm.
Recovery can be different for each person. A person may experience minor or major physical, cognitive, and emotional changes. These changes may be short term or long term. For example, a person may experience problems with their memory, which can ease over time.
Survivors of brain aneurysms and other brain injuries can still lead a completely normal and healthy life, though they oftentimes need to adjust in large and dramatic ways to their new way of living.
With rapid, expert treatment, patients can often recover fully. An unruptured brain aneurysm may cause zero symptoms. People can live with them for years before detection. If a brain aneurysm is unruptured, no blood has broken through the blood vessel walls.
Magnetic resonance angiography (an MRI scan) is usually used to look for aneurysms in the brain that haven't ruptured. This type of scan uses strong magnetic fields and radio waves to produce detailed images of your brain.
Brain aneurysms can occur in anyone and at any age. They are most common in adults between the ages of 30 and 60 and are more common in women than in men.
The weakness in the wall of a vessel leads to ballooning or bulging, which can eventually lead to a rupture of the wall. “When it ruptures,” Dr. Shekhtman says, “the blood comes out of the artery and damages whatever brain structures are near.” An aneurysm can lead to a stroke, but a stroke won't lead to an aneurysm.
Up to 6% of people living in the United States have an unruptured brain aneurysm. While still rare, they do happen to up to 30,000 Americans each year. Brain aneurysms occur in both males and females and at any age, but brain aneurysms are most common in female adults between ages 40 and 60.
Risk factors for developing or having bleeding from an aneurysm also include high blood pressure, smoking, and excessive alcohol use. If you have any risk factors for developing an aneurysm, it's important discuss screening tests and treatment options with your healthcare provider.
Devastation Caused by Aneurysms
Ruptured brain aneurysms are fatal in about 50% of cases. Of those who survive, about 66% suffer some permanent neurological deficit. Approximately 15% of people with a ruptured aneurysm die before reaching the hospital.
