Brain aneurysms may run in families. If brain aneurysms run in your family, you are more at risk of having a brain aneurysm than the average 3%. Your risk depends on how many relatives have been affected, and how many closely related to you they are.
Can brain aneurysms be genetic?
In most cases, brain aneurysms are not hereditary, and there is generally only a single case in a family. Occasionally, however, an individual with a brain aneurysm will have other family members who are affected.
