Know the Facts on Brain Aneurysms

Brain Aneurysm awareness and prevention starts with finding a trusted resource and understanding the facts.

Did You Know?: Brain Aneurysm Statistics and Facts

Brain aneurysms are complex and dangerous medical issues that require early detection, accurate diagnosis, and prompt treatment to maximize survivability. Left unchecked, a brain aneurysm is essentially a biological time bomb that can have devastating results. Driving awareness about brain aneurysms and advocating for further research into brain aneurysm treatment could potentially offer people increased chances of surviving their brain aneurysms. It’s also essential to know some key statistics concerning brain aneurysms and to separate fact from myth. 

Brain Aneurysms

are most prevalent in people ages 35 – 60, but they do not discriminate and occur in children and seniors alike. The median age when a Brain Aneurysm occurs is 50 years old and there are no warning signs in many instances. Most aneurysms develop after the age of 40.

75% of all brain aneurysm ruptures

 result in either death or permanent disability. Very few people who experience subarachnoid hemorrhages will regain pre-rupture functions and will likely develop some type of permanent neurological impairment.  

Women between the ages of

40 and 60 face a 50% higher risk of developing brain aneurysms than other demographic groups. 

Hospital costs

for clipping or coiling treatments can approach $50,000 or more.  

Women over the age of 55

are 1.5 times as likely to develop brain aneurysms than men in the same age group.

Four of every seven people

who survive brain aneurysm ruptures will develop permanent disabilities.  

Of all the brain aneurysm ruptures

that occur in the US each year, about 50% will result in death within a few days. 

Most aneurysms

are between 1/8 of an inch to less than one inch in size. Aneurysms larger than one inch in diameter qualify as “giant” aneurysms.  

The median age

for brain aneurysms to occur is 50, and the age group most commonly afflicted by brain aneurysms is the 35 to 60 age range. Most brain aneurysms develop after age 40. 

25% of people

who experience brain aneurysm ruptures die within 24 hours. Another 25% die within two to three days, and another 25% die from related complications within six months.  

Some lifestyle choices

greatly increase the risk of developing brain aneurysms. For example, smoking not only increases the chances of developing a brain aneurysm, but also increases the chances of a person developing multiple aneurysms.  

Hispanic-Americans and African Americans

are estimated to be 25% more at risk of developing a Brain Aneurysm 

Nearly 5%

of all emergency room admissions for severe headaches happen due to ruptured aneurysms. 

An estimated

40,000 brain aneurysms rupture in the United States each year.  

These statistics should encourage all readers to take appropriate steps if they suspect the appearance of brain aneurysm symptoms in themselves or others. Prompt identification and treatment can mean the difference between life and death. Available treatments continue to improve and offer positive results for those with diagnosed unruptured brain aneurysms. Awareness of the dangers and warning signs of brain aneurysms could potentially save millions of lives in the future.
