This is probably the right time to remind people that Brain injuries are unique in the fact that it is impossible to determine the severity or length of the injury by watching the incident that caused it.
Every single brain injury is different. You can be knocked out cold and pass all the concussion protocol and show no I'll effects in the short term.
However, You can also take a much less harmful impact to the head and not even realize you've been injured until days later and the recovery may take months.
New research has also suggested that knockout type events don't contribute any more or less to formation of CTE compared to smaller impacts. I.E. frequently getting reapeted blows to the head (think boxers or football linemen/running backs) is actually the main culprit of CTE and even being concussed or rendered unconscious is not the largest worry.
In this case there didn't even appear to be any direct contact to the head. It was just shaken very sharply. But there was obviously brain injury of some type or some severity.
