Mom had an aneurysm 6 years ago. Somehow she felt 'weird' and called an ambulance. Died twice on the operating table and was induced into a coma for 2 months. They implanted some sort of metal coil in her brain where it was.
My question, is whether they are hereditary or not. A friend said her family has a run of them through her aunt and cousins, but another Doctor said it was never hereditary.
