Brain Aneurysm

For more than 15 years, Dr. Badih Adada has been working as a neurosurgeon. Currently working for Cleveland Clinic in Florida, he provides surgical treatments for complex pathologies of the brain. Board certified by the American Board of Neurological Surgeons, Dr. Badih Adada specializes in skull base and vascular neurosurgery, as well as brain aneurysms.

Brain aneurysms are most commonly located in the Circle of Willis, which is a junction of four arteries near the base of the brain. They result from a thinning of the artery walls and can be caused by several different things. Although aneurysms don’t form solely because of genetics, there is a link between the condition and family history. Individuals who have a family history of brain aneurysms are more likely to develop one than those with no family history. Further, personal history of aneurysms results in an increased risk of developing a second or third aneurysm later on.

There have been links made between the risk of brain aneurysms and gender and race. In general, African-Americans are more likely than whites to experience a subarachnoid hemorrhage. Women are also more likely to suffer this and they are more at risk of developing an aneurysm. High blood pressure, trauma, and abnormal blood flow in the Circle of Willis also increase risk. Once a brain aneurysm has formed, excessive exercise, sexual intercourse, and intense anger can all increase the risk of the aneurysm rupturing.
