I am confused. What kind of help are you looking for?

Most concussions have diffuse axonal injury as a major component. Whether there is a bit of coup-contra-coup focal injury is hard to diagnose, especially in a non-specific concussion. The concussed brain with a heavy load of stress will likely be a neuro-chemical mess. Treatment is usually focused on treating the symptoms.

Imaging a concussion rarely shows any abnormality. Small brain bleeds usually show up at about the third day and are absorbed quickly thereafter. A high resolution MRI may show some problems but rarely will a normal resolution (1.5 Tesla) show any problems.

Brain mapping (qEEG) can show the dysfunctions in waveforms, etc. but are rarely used with concussion. qEEG is commonly used to diagnose ADD/ADHD.
