Alas no, brain aneurysms don't have to have any outward symptoms at all until they strike, and then you're dead within minutes.

You can spot some issues before they kill you if you have a brain scan, but as you've got no symptoms, why would you be having a brain MRI once a month?

So, alas, it's a silent, deadly killer. One day you just drop dead for seemingly no reason.

RIP Grant, you were fuckin rad.
