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. People with certain inherited disorders are also at higher risk.
Brain aneurysms are most prevalent in people ages 35 to 60, but can occur in children as well. Most aneurysms develop after the age of 40. Women, particularly those over the age of 55, have a higher risk of brain aneurysm rupture than men (about 1.5 times the risk).
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.
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.
Yes, you can live with an aortic aneurysm, and there are many ways to prevent dissection (splitting of the blood vessel wall that causes blood to leak) or worse, a rupture (a burst aneurysm). Some aortic aneurysms are hereditary or congenital, such as bicuspid aortic valve, infection or inflammatory conditions.
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.
An unruptured brain aneurysm may not have any symptoms, especially if it's small. However, a larger unruptured aneurysm may press on brain tissues and nerves. Symptoms of an unruptured brain aneurysm may include: Pain above and behind one eye.
Strong emotions, such as being upset or angry, can raise blood pressure and can subsequently cause aneurysms to rupture.
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.
A brain aneurysm is usually diagnosed using angiography. Angiography is a type of X-ray used to check blood vessels. This involves inserting a needle, usually in the groin, through which a narrow tube called a catheter can be guided into one of your blood vessels.
You should see a GP as soon as possible if you experience symptoms of an unruptured brain aneurysm. Although most aneurysms will not rupture, it's important to get it checked in case treatment is necessary.
Depending on the risk factor burden, the lifetime risk of an aneurysmal SAH varied from 0% to 100%, and the annual rupture rate from 0% to 6.5%. Of the 96 patients with small (<7 mm) UIAs, 24 (25%) had an aneurysmal SAH during the follow-up.
“An aneurysm usually grows slowly, around 1–2mm per year. Once it reaches a certain size, the risk of it rupturing (bursting) becomes too high and surgery is needed to repair it.” An aneurysm is usually classed as large once it reaches 5.5cm.
What are the chances of surviving aneurysm surgery? Aneurysm surgery is very serious if performed after an aneurysm rupture. The chance of survival after surgery for a ruptured aortic aneurysm is 50% to 70%. The greatest threat comes from complications of the rupture, including kidney failure.
There are, however, some important differences. The pain from a ruptured brain aneurysm is often described as the worst headache of a person's life. The pain comes on more suddenly and is more severe than any previous headaches or migraines. In contrast, migraine headaches usually come on gradually.
In a study of about 70,000 adults, researchers found that people with a genetic predisposition to insomnia were at somewhat higher risk of a brain aneurysm. An aneurysm is a weak spot in an artery wall that bulges out and fills with blood. In some cases, it can rupture and cause life-threatening bleeding.
If your aortic aneurysm ruptures, you will feel a sudden and severe pain in the middle or side of your abdomen. In men, the pain can also radiate down into the scrotum. Other symptoms include: dizziness.
They are most common in adults between the ages of 30 and 60 and are more common in women than in men. People with certain inherited disorders are also at higher risk. Sometimes cerebral aneurysms are the result of inherited risk factors, including: genetic connective tissue disorders that weaken artery walls.
One of the most obvious signs of a ruptured aneurysm is intense head pain, typically described as the worst headache of your life. Additional symptoms of a ruptured aneurysm include: Nausea and vomiting. Double or blurred vision.
The most common and deadly aneurysm is aortic. Two-thirds of aortic aneurysms are abdominal (AAA), and one-third is thoracic (occurring in the chest cavity). When the aneurysm occurs in both areas, it is called thoracoabdominal.

Nearly 24% of those receiving medical treatment alone died within two days, compared to 4.4% of patients treated with surgical repair – a death rate more than 5 times higher.
The survival rate for those with a ruptured brain aneurysm is about 60% (40% die). For those who survive and recover, about 66% have some permanent neurological defect.
