I have a question of anyone that might know if there is much success with successfully showing a service connection for TBI claim from stateside training?
I was injured in a parachuting accident on base during a night time operation.  I have service records that state I received an evaluation after the incident mentioned.  No major testing or evaluation just that I had an injury and "hit my head pretty hard."  That is the exact wording in my service medical records.  I am already service connected(20% cervical spine) from this same injury and the above mentioned evaluation in my records is referenced in the decision letter.
I have very compelling medical evidence(neuropsychological evaluation) that I have a TBI, just not sure if this reference is enough to show that the condition that has been well documented is service connected.  I have been exposed to many IED's overseas, but like everyone else I did not seek treatment as I was not bleeding and I was awake so I just moved on.  Only to feel the effects later.  So I do not have anything other than the stateside accident to show a head injury in my service medical record

If you were combat than the VA must accept your written statement in relation to your claim. So I'd write a well written statement describing the IED exposure while in combat. Find some of your fellow comrades and have them also write a statement describing such.

I think that multiple closed head injuries is the key to your claim. Start with the stateside evidence and move on to the IED's.

Thanks for the reply, I think I have become lazy with my written statements. My medical records, both civilian and service are very extensive and well documented and sometimes I don't even see the point. I know this is a bad habit, but my last claim of cervical disk injury I did not even write a statement. I just sent in a civilian MRI that showed damage and my service records that showed injury to my neck and head and poof, 20% for cervical disk injury. I think I will need the written statement at the least for a guide to whoever is rating my claim as to where to find all the evidence in my records.
