I have an IME from a neurologist and he said the following.
He has classic TBI signs and symptoms (as per the VA guide for TBI examination) of headaches, dizziness, weakness, sleep disturbance, fatigue, balance issues short term memory problems, bladder problems, hypersensitivity to sound (as per his attached lay statement and clinical exam) and he was exposed to blast injuries in service with likely TBI (traumatic brain injury) as per my clinical interview and my review of his brain MRI report which describes findings consistent in my medical opinion with old trauma (“…T-2 hyperintensity…right inferior frontal lobe…frontal operculum….may represent prior trauma… Dr. Levy…”.) I understand that Dr. Levy used the word may but an injury in the operculum is a classic location for trauma to be manifest as the brain hits the inner regions of the skull in this area during trauma and causes encephalomalacia which is visualized as increased T-2 signal. This patient has increased T-2 signal in his operculum and therefore it is my opinion that this is most likely due to his service time trauma as this is a classic location for post trauma brain injury.
It's mostly greek to me but he does correlate the brain trauma to the event. So I'm hoping for the best. I'm currently 50% PTSD and 10% Tinnitus so I hope this adds to my compenstaion and I hope they don't lump the TBI issues into the PTSD.
