My claim went back to gathering of evidence after I had my second c&p exam for tbi initial. My vso the Dav said it was a dbq to differentiate the symptoms of tbi and PTSD as far as social and occupational impairment. I recieved at least as likely as not on all exams, PTSD, both tbi exams. Has anyone experienced this or know what it means? Is this a good sign my claim will be granted ? Thank you.
