Mark Swaim, MD, PhD knows that those who have suffered a brain aneurysm once may be curious if they can suffer a second one. The answer, unfortunately, is yes, you can. Emilia Clarke, famous for her role as Daenerys Targaryen in Game of Thrones, is an example of the possibility of suffering more than one aneurysm.
But if you or someone you know has already had one brain aneurysm, what are the chances that another one may happen?
Increased Risk of a Second Aneurysm
According to certain studies, many risk factors can raise the chances for a second aneurysm. At least 20% of those who have suffered one aneurysm in the past are likely to suffer another one in the future.
Mark Swaim, MD, PhD, says if the patient is a regular smoker, the risk increases further. Chances for another brain aneurysm also increases if the patient suffers from high blood pressure. This is why doctors will immediately and strongly recommend a lifestyle change to their high-risk patients.
Females and Increased Risk
Female patients are more likely to suffer aneurysms than males, with a ratio of 3:2 (female to male). The risk also increases in women who are older than 40-years-old. At 55 and above, females run a higher risk of a ruptured brain aneurysm than males, with as much as 1.5x the male risk.
Chances of Survival in Ruptured Aneurysms
Mark Swaim, MD, PhD says those who suffer a ruptured aneurysm have a 50% chance of surviving. However, 66% of those who survive a brain aneurysm rupture end up suffering from permanent neurological damage.
To increase your chances of survival, see a neurologist immediately if you suffer from persistent headaches and pain behind the eyes. Follow your doctor’s orders when it comes to lifestyle changes you must make. Mark Swaim, MD, PhD says you should also keep all your follow-up appointments, especially if you are at an increased risk of aneurysm.
