Individual and joint malingering detection accuracy of the Portland Digit Recognition Test (PDRT), Test of Memory Malingering (TOMM), and Word Memory Test (WMT) was examined in traumatic brain injury (TBI; 43 non-malingering, 27 malingering) and chronic pain (CP; 42 non-malingering, 58 malingering) using a known-groups design. At published cutoffs, the PDRT and TOMM were very specific but failed to detect about 50% of malingerers; the WMT was sensitive but prone to false positive errors. ROC analyses demonstrated comparable accuracy across all three tests. Joint classification accuracy was superior to that of the individual tests. Clinical and research implications are discussed.

Among the myriad of complications associated with traumatic brain injury (TBI), impairments in social behaviors and cognition have emerged as a significant area of concern. Animal models of social behavior are necessary to explore the underlying brain mechanisms contributing to chronic social impairments following brain injury. Here, we utilize large-scale brain recordings of local field potentials to identify neural signatures linked with social preference deficits following frontal brain injury.

Introduction Traumatic brain injury (TBI) is a major health concern due to its poor clinical and functional outcome and its impact on family homeostasis. Often, the stressed and anxious family is not involved in the care process until the rehabilitation phase. This study aimed to evaluate the integration of family involvement in the neuro-intensive care of TBI patients on family satisfaction.

Operational environments are characterized by a range of psycho-physiological constraints that can degrade combatants' performance and impact on their long-term health. Neurofeedback training (NFT), a non-invasive, safe and effective means of regulating brain activity, has been shown to be effective for mental disorders, as well as for cognitive and motor capacities and aiding sports performance in healthy individuals. Its value in helping soldiers in operational condition or suffering from post-traumatic stress (PTSD) is undeniable, but relatively unexplored.

White blood cell (WBC) subtypes reflect immune and inflammatory conditions in patients. This study aimed to examine the association between the ratio of platelets to WBC subtypes and mortality outcomes in patients with moderate-to-severe traumatic brain injury (TBI). The Trauma Registry System of the hospital was retrospectively reviewed to gather medical records of 2397 adult patients who were hospitalized from 2009 to 2020 and had moderate-to-severe TBI with a head abbreviated injury scale (AIS) score of 3 or higher.
