Summary: The study compared the trajectory of recovery using three measures in TBI patients, finding that CAP detected recovery earliest while WPTAS detected it latest. CAP and GOAT showed good agreement on PTA status, but both had poor agreement with WPTAS.

Summary: This study aimed to investigate the relationship between MRI findings of traumatic axonal injury (TAI) and admission Glasgow Coma Scale (GCS) score and prolonged duration of posttraumatic amnesia (PTA) after traumatic brain injury (TBI). The results showed that the location and burden of TAI lesions were significantly associated with GCS score and duration of PTA. Specifically, bilateral TAI lesions in the thalamus and the total volume of TAI lesions on FLAIR were found to have the strongest predictive value for prolonged PTA.

Summary: The study aimed to create a composite instrument for detecting changes in cognitive and behavioral function over time in individuals exposed to repetitive head impacts. Data from the Professional Fighters Brain Health Study were used to establish a weighted linear value of standardized scores, showing better sensitivity compared to individual measures.

Summary: TGA and post-traumatic amnesia can both result in hyperintense lesions in brain MRI, but they have different etiologies and clinical presentations.

Summary: The study found that head injury, PTSD, and depression were prevalent in civilian women. The combination of PTSD and depression was associated with worse cognitive performance, especially among women with a history of head injury. Further exploration of head injury in relation to PTSD, depression, and cognition in women is needed for future studies.

Summary: Posttraumatic amnesia (PTA) is a common symptom following moderate to severe traumatic brain injury, characterized by confusion, amnesia, poor attention, and agitation. An international team of researchers and clinicians have developed guidelines for PTA management, including daily assessment using a validated tool and minimizing agitation and confusion through environmental adaptations, physical therapy, and daily living training.

Summary: The study found that an external observer could see as many as six (s, Delta mag)-coincidence locations between the Earth and other solar system planets. By varying system inclinations, 36%-69% of inner planet orbits and 1%-4% of outer planet orbits share at least one (s, Delta mag)-coincidence with the Earth.

Summary: Physical therapy is important in the management of traumatic brain injury (TBI) and associated multi-trauma. However, providing therapy during the posttraumatic amnesia (PTA) phase is challenging due to confusion, amnesia, agitation, and fatigue. This observational study aimed to explore the frequency, duration, location, and engagement of physical therapy provision during PTA and the impact of cognition, agitation, and fatigue.

Summary: Motorcycle-associated head injury mainly affects young men who use motorcycles for commercial purposes. Survival is higher among patients who undergo brain CT scans, have extra-axial clots, and receive operative treatment. However, patients who cannot afford brain CT scans, have bilateral pupillary dilatation, CT findings that are not surgically treatable, and severe head injury may have a higher mortality rate.

Summary: In this retrospective chart review, it was found that post-rehabilitation Cognitive and Linguistic Scale (CALS) scores were associated with the Glasgow Outcome Scale-Extended, Pediatric Revision (GOS-E Peds) outcomes for children with traumatic brain injury (TBI). Time to follow commands (TFC) and TFC+PTA were also correlated with GOS-E Peds outcomes at follow-ups. Glasgow Coma Scale (GCS) and posttraumatic amnesia (PTA) were not predictive of GOS-E Peds outcomes.

Summary: This retrospective study analyzed clinical data of 283 acute trauma patients and found that Trauma Index (TI) performed the best in predicting early mortality risk, while different types of shock indices also had certain predictive value for early mortality risk in trauma patients.

Summary: Improved evidence on head impacts in ice hockey can help enhance brain health protection through advancements in protective gear, rink design, player training, and rules of play. This observational cohort study found that shoulder-to-head impacts were more common, head-to-glass impacts were nearly four times more frequent, and impacts resulting in major penalties or visible signs of concussion involved higher head rotational velocities. The study also revealed that most head impacts occurred to the side of the head along the boards in the offensive zone.

Summary: Barash and colleagues have used a statewide database to identify potential cases of opioid-associated amnestic syndrome, which is a valuable contribution to the epidemiology of this condition. However, it does not determine whether opioids truly cause the observed amnesia, and suggests the need for further research to address this question.

Summary: Mitigating the significant public health impact of concussion is difficult due to its prevalence and symptom-based diagnosis. This review examines emerging approaches to objectively evaluate potential concussion and highlights areas where further research is needed. Objective assessments of symptoms, specialized imaging techniques, and specific biomarkers show promise for accurately characterizing brain injuries. The consolidation of these approaches will improve precision in concussion diagnosis and treatment.
