Thank you for the reply carlie, below is exactly what the letter states,
Traumatic brain injury (TBI)
Service connection may be granted for a disability which began in military service or was caused by some even or experience in service. Service connection for traumatic brain injury (TBI) is denied because the medical evidence of record fails to show that this disability has been clinically diagnosed.
Upon examination on May 3, 2014 the examiner found that you do not meet the criteria for a diagnosis of TBI. With your receipt of the Combat Action Badge we requested the VA examination and asked the examiner to opine on the connection of any TBI diagnosis with the acknowledged events leading to your Combat medal. No diagnosis was found, therefore, service connection for traumatic brain injury (TBI) is denied.
Headaches
Service connection may be granted for a disease or injury which resulted from a service connection disability or was aggravated thereby. The evidence does not show that traumatic brain injury (TBI) is related to service. Therefore, service connections for headaches on a secondary basis to this condition cannot be established. There is no evidence showing headaches was incurred in or aggravated by military service.
Also, I called VA to ask what this ment. I was told something about without a TBI diagnosis the examiner could not say I had TBI. I am totally comfused. I was told that the combat action badge (that i recieved for the IED attack) did not state what it was for. I sent in my DA Form 638 that states I was involved in an IED, but after reveiwing the list of evidence considered DA Form 638 was not listed. I am 100% sure I included it when I sent in my packet. I have requested the C&P exam notes and will be requesting my C-file. I have already set up an appointment with a private neurologist for next week. I plan on appealing the desicion and sending in a DBQ and Nexus letter.
