Studies from Australia, as well as British medical journals have shown what most of us have long suspected. That is, that ER personnel are not keen on wading into a diagnosis of mild TBI. This is a major concern for those headed into TBI litigation because the EMT and ER records form the foundation for the presence or absence of TBI, according to the insurance companies. A recent article in the Journal of Neurotrauma from 2019 shows that the diagnosis of mild TBI is difficult because the symptoms are vague and not specific. After looking at the records of 1600 patients, they found that less than half of those with a confirmed TBI were actually diagnosed with a mild TBI.
