MammaMia,

Welcome to NeuroTalk. I'm sorry to hear about your son.

The research I have read says that bleeds from the initial impact show up on CT Scans best at 72 hours post injury. This is enough time for a slow bleed to become large enough to be discernible and before it starts to be absorbed.

His neuro or a neuro-radiologist should be able to explain this for your son's situation.

Pushing him in rehab will not cause more damage. But, pushing too hard can be ineffective by causing stress that impedes progress. There is difference between rehabbing after a coma where brain functions become dormant and need effort to wake them up and the issues common to concussions. Coma based rehab is often considered successful when the patient reaches the level of function that concussion patients start at. From that point, further recovery will likely be much slower.

The migraines comment has been mentioned before. Some neuros do not believe concussions can have long term deficits and blame residual struggles on other causes.

So, how is your son doing ? What are his current struggles ? Has he had a Neuro Psychological Assessment done ?
