All of the above mentioned in the title is types of strokes, am I correct? Does this imply that all of these, if they were to occur from open head injury, would definitely cause stroke symptoms? If yes, even the slightest cut to actual brain tissue causing the least amount of blood to leak possible, would still cause stroke symptoms since it logically also has to pass through the other intracranial layers covering the brain tissue?

This is still in relation to the "pointy/edgy object skull penetration" matter.

(sorry, back for this one, since I figured this site would be better equipped with the knowledge to respond with more thorough answers).
