My mom's grandfather passed away from an aneurysm in his 40s. Her brother died of an aneurysm in his 20s. Her younger sister had some sort of brain-blood-vessel anomaly related to a benign tumor, but she had it removed. My mom had an aneurysm burst in her 70s but she survived. Her neurologist said that all my great-grandpa's descendents should get brain MRIs to determine if we have the same problem. Several of my siblings and our kids got brains scans, but nobody found anything to report on them. Meanwhile, two of my mom's younger sisters (both in their 70s) just passed away since 2021 from pancreatic cancer. Scary stuff.
