Male Speaker: Well, it's fundamental, the skull is very hard and the brain is very soft and they don't always move together. So when the skull stops suddenly, the brain continues moving and it collides with the inner surface of the skull. And furthermore, once the brain starts swelling, there is only one way out in that compartment and it's through these openings at the base of the brain.
And the syndrome that occurs from pressure due to a growing hematoma is called Herniation, that is, the brain tissue gets forced through these narrow openings and that process stretches blood vessels, damages the brain, causes bleeding to occur in the brain. So, that is a catastrophic event, when that occurs from a growing hematoma.
Male Speaker: And that's why some people use the word, walk and talk or then talk and die syndrome is because there is this lucid interval, things quickly, the pressure, quickly grows in the skull and the minute the herniation occurs, it's pretty much brain death instantly.
