Since 2006, efforts have been made to increase the accurate identification of traumatic brain injuries (TBIs) in post-9/11 military personnel. The Boston Assessment of TBI-Lifetime (BAT-L) is the first validated instrument designed specifically to diagnose TBIs throughout the life span in post-9/11 Veterans. The objective was to compare the diagnostic accuracy of the BAT-L with medical records from the Department of Defense (DoD). ⋯ This study addresses a critical gap in research by comparing the diagnostic accuracy of a validated, semi-structured clinical interview with available medical records. Diagnosis of TBIs via the BAT-L was both sensitive and specific when compared to DoD records, supporting the validity of the BAT-L for retrospective assessment of military TBI. However, diagnostic correspondence was only fair. This lack of diagnostic agreement was related to multiple factors including lack of documentation at the time of injury by DoD, differences in assessment and goals, and other combat-related motivational factors associated with failure to report injuries while deployed. Several policies have been implemented to address underreporting and under-documentation of TBIs, yet challenges remain. Recommendations for evaluating TBI are presented. Accurate diagnosis of TBI is necessary for appropriate treatment planning, as well as service-related compensation.

Posttraumatic stress disorder (PTSD) and depression are common in service members and veterans, and the response to currently available treatments is often modest at best. Recent studies suggest potential benefit with psychedelic-assisted therapies (PATs), particularly 3,4-methylenedioxymethamphetamine-assisted therapy for PTSD and psilocybin-assisted therapy for depression. This study examined beliefs and perceived barriers regarding PAT among service members and veterans to inform the delivery of these treatments if they are approved by the FDA. ⋯ This is the first study to explore beliefs and perceived barriers regarding PAT among service members and veterans. These results indicate that military populations may be interested in PAT, particularly if psychoeducation and outreach regarding these treatments occurred. If FDA approved, it will be important to facilitate command support and address logistical barriers to ensure appropriate access within military contexts.

Post-traumatic seizure (PTS) prophylaxis is recommended in patients with traumatic brain injury (TBI) at high risk for PTSs, but consensus on the optimal pharmacologic therapy has not yet been established. Levetiracetam is frequently used for seizure prophylaxis in combat-related TBI, but its efficacy and safety in this patient population has not yet been described. ⋯ Levetiracetam appears to be a safe and effective medication for PTS prophylaxis in combat casualties. The rate of PTSs in combat-related TBI on appropriate prophylaxis is low.

Observational StudyOptic nerve diameter on non-contrast computed tomography and intracranial hypertension in patients with acute brain injury: A validation study.
Intracranial hypertension is a feared complication of acute brain injury that can cause ischemic stroke, herniation, and death. Identifying those at risk is difficult, and the physical examination is often confounded. Given the widespread availability and use of computed tomography (CT) in patients with acute brain injury, prior work has attempted to use optic nerve diameter measurements to identify those at risk of intracranial hypertension. ⋯ When used to identify those with intracranial hypertension (> 20 mm Hg), the area under the receiver operator curve (AUROC) was 0.68. Using a previously proposed threshold of 0.6 cm, the sensitivity was 81%, specificity 43%, positive likelihood ratio 1.4, and negative likelihood ratio 0.45. CT-derived optic nerve diameter using a threshold of 0.6 cm is sensitive but not specific for intracranial hypertension, and the overall correlation is weak.
