  As far as I am aware, strokes happen either because something (like a blood clot) stops blood, and therefore oxygen, from reaching the brain, or because one of the blood vessels in the brain starts bleeding. I think that having high cholesterol can increase the chances of having a stroke (see: https://www.nhs.uk/conditions/high-cholesterol/), but I’m not a medical doctor – I just like insects.
