We certainly have our cases of traumatic brain injury, but I would advise you to.... If you take a careful look at the very recent article in The New England Journal of Medicine, what it says is not that post-traumatic stress disorder isn't really post-traumatic stress disorder, but really MTBI. What it says is that having had a concussion and having had that kind of disruption to your brain, whether you've lost consciousness or whether you just had your bell rung and saw stars--having had that distortion on top of all the other things puts you at higher risk of PTSD.
What it's really saying is to screen very carefully people who've been through these kinds of explosions for PTSD. It's not saying you've got the diagnosis wrong and it's not PTSD. A lot of people who got the press clippings version of the article missed that point.
