SETTING: Department of Veterans Affairs (VA) medical centre and five affiliated community-based outpatient clinics. PARTICIPANTS: Three hundred and fifty Iraq and Afghanistan veterans with positive initial VA TBI screens between 1 April 2007 and 1 June 2010 and clinician-confirmed TBI status by 1 December 2010. METHODS: Retrospective-cohort study of medical record data. Main measures included clinician-confirmed TBI status, injury severity markers (e.g. loss of consciousness (LOC), post-traumatic amnesia (PTA) or confusion/disorientation) and neurological symptoms. RESULTS: Among veterans who screened positive on the initial VA TBI and then received a clinician evaluation, 60% were confirmed to have a TBI diagnosis. Veterans reporting at least one LOC, confusion or PTA were almost 18-times more likely to receive a confirmed TBI diagnosis. Odds of clinician-confirmed TBI were 2.5-3-times greater among those who endorsed dizziness, poor coordination, headaches, nausea, vision problems and/or irritability, compared to those not endorsing these symptoms. Nausea had greatest utility for confirming a TBI. CONCLUSIONS: Identification of neurologic symptoms that most contribute to a clinician-confirmed diagnosis of TBI has potential for streamlining detection of TBI and symptoms needed for treatment.},

Mild TBI or concussion is now well recognized to be a risk of military service as well as participation in athletic sports such as football. Posttraumatic headache (PTH) is the most common symptom after mTBI in US service members. PTH most commonly presents with migraine-like headache features. The following is an overview of the epidemiology, pathophysiology, clinical course, prognosis, complications, and treatment of mTBI and associated comorbidities with a focus on PTH. There is a particular emphasis on emerging evidence-based clinical practice. One important medical consequence of the recognition that mTBI is a highly prevalent among military service members is that the Department of Defense (DoD) is dedicating significant financial and intellectual resources to better understanding and developing treatments for TBI. The identification of the importance of TBI among the US military population has had the added benefit of increasing awareness of this condition among civilian populations, particularly those engaged in both professional and youth sports.

Unfortunately, the understanding of the acute and chronic effects of mTBI on the brain remains limited.

Follow-up ANAM testing was performed 10 d after initial testing (±5 d). Twenty-one soldiers were excluded: two for poor effort and 19 who had combined blast/blunt injuries. Of the remaining 50 male participants, 34 had blast injuries and 16 had blunt injuries. There were no statistically significant differences between blast injury and blunt injury participants in demographic, physical, or psychological health factors, concussive symptoms, or automated and traditional neurocognitive testing scores within 72 h post-injury. In addition, follow-up ANAM scores up to 15 d post-injury were not significantly different (available on 21 blast-injured and 13 blunt-injured subjects). Pre-injury baseline ANAM scores were compared where available, and revealed no statistically significant differences between 22 blast injury and eight blunt injury participants. These findings suggest there are no significant differences between mechanisms of injury during both the acute and subacute periods in neurobehavioral concussion sequelae while deployed in a combat environment.

Test data was used to drive a computer model (DYNAMAN) to estimate the loads and torques in the neck during impact. Currently, only seven of eleven test cells with variations in the inertial properties of the helmet along the x-axis of the head have been analyzed. Preliminary data analysis indicates that the biodynamic response of the head under the tested conditions is slightly more sensitive to the moment of inertia of the helmet than its weight alone even though both variables showed a general trend for the head accelerations (linear and angular) to increase. It has been shown that the model can give good estimates of the compression loads in the neck, but that the torque estimates will be low, possibly by a factor of three. Further refinements of the neck joint parameters in the model will be required in order to increase the motion of the head segment during impact acceleration and will be done prior to completing the remaining test cell analysis. Finally, all the test data will be evaluated to determine if the current interim head criteria require modification.},

abstract = {The objective of the test program was to study the effect of parametric changes in helmet inertial properties on the biodynamic response of human volunteers subjected to +Gz impact accelerations. Test data was used to drive a computer model (DYNAMAN) to estimate the loads and torques in the neck during impact. Currently, only seven of eleven test cells with variations in the inertial properties of the helmet along the x-axis of the head have been analyzed. Preliminary data analysis indicates that the biodynamic response of the head under the tested conditions is slightly more sensitive to the moment of inertia of the helmet than its weight alone even though both variables showed a general trend for the head accelerations (linear and angular) to increase. It has been shown that the model can give good estimates of the compression loads in the neck, but that the torque estimates will be low, possibly by a factor of three. Further refinements of the neck joint parameters in the model will be required in order to increase the motion of the head segment during impact acceleration and will be done prior to completing the remaining test cell analysis. Finally, all the test data will be evaluated to determine if the current interim head criteria require modification.},
