My sister unexpectedly passed away 4 weeks ago at age 45 due to a brain aneurysm rupturing. She was in a coma on life support for 3 days. Brain aneurysms can be genetic and there have been 4 in my family in the past 10 years with only one person surviving. I have had horrible headaches all my life and am going in for an MRI angio July 13. I am scared they will find an aneurysm in my brain as well even though I know it is best they find it and treat it before it ruptures and causes my death. Does anyone have any experience with treating an aneurysm before it ruptures?
