AbstractThe mild traumatic brain injury (mTBI) results in traumatic axonal injury, which damages the long-distance white matter (WM) connections and thus disrupts the functional connectome of large-scale brain networks that support cognitive function. Patterns of WM structural damage following mTBI were well documented using diffusion tensor imaging, however, the functional organization of WM and its association with grey matter functional networks (GM-FNs) and cognitive assessments remains unknown. The present study adopted resting-state functional magnetic resonance imaging to explore WM functional properties in mTBI patients (113 acute patients, 56 chronic patients, 47 healthy controls (HCs)). Eleven large-scale WM functional networks (WM-FNs) were constructed by the k-means clustering algorithm which carried out in voxel-wise WM functional connectivity (FC). Compared to HCs, acute mTBI patients showed enhanced FC between inferior fronto-occipital fasciculus (IFOF) WM-FN and primary sensorimotor WM-FNs, and cortical primary sensorimotor GM-FNs. And FC between IFOF WM-FN and anterior cerebellar GM-FN was positively correlated with information processing speed. Moreover, all of these WM-FNs abnormalities were returned to the normal level at the chronic stage. Our findings suggest the compensatory mechanism of cognitive deficits in the acute stage and its involvement in facilitating recovery from cognitive deficits in the chronic stage. The convergent damage of the IFOF network highlighted its key role in our understanding of the pathophysiology mechanism of mTBI patients and thus might be regarded as a biomarker in the acute stage and a potential indicator of treatment effect.

Purpose The Centers for Disease Control and Prevention (CDC) recently released guidelines for rehabilitation professionals regarding the care of children with mild traumatic brain injury (mTBI). Given that mTBI impacts millions of children each year and can be particularly detrimental to children in middle and high school age groups, access to universal recommendations for management of postinjury symptoms is ideal. Method This viewpoint article examines the CDC guidelines and applies these recommendations directly to speech-language pathology practices. In particular, education, assessment, treatment, team management, and ongoing monitoring are discussed. In addition, suggested timelines regarding implementation of services by speech-language pathologists (SLPs) are provided. Specific focus is placed on adolescents (i.e., middle and high school–age children). Results SLPs are critical members of the rehabilitation team working with children with mTBI and should be involved in education, symptom monitoring, and assessment early in the recovery process. SLPs can also provide unique insight into the cognitive and linguistic challenges of these students and can serve to bridge the gap among rehabilitation and school-based professionals, the adolescent with brain injury, and their parents. Conclusion The guidelines provided by the CDC, along with evidence from the field of speech pathology, can guide SLPs to advocate for involvement in the care of adolescents with mTBI. More research is needed to enhance the evidence base for direct assessment and treatment with this population; however, SLPs can use their extensive knowledge and experience working with individuals with traumatic brain injury as a starting point for post-mTBI care.

Abstract Background: Mild traumatic brain injury (mTBI) is recognized as the signature injury of the current conflicts in Iraq and Afghanistan, yet there remains limited understanding of the persisting cognitive deficits of mTBI sustained in combat. Speech-language pathologists (SLPs) have traditionally been responsible for evaluating and treating the cognitive-communication disorders following severe brain injuries. The evaluation instruments historically used are insensitive to the subtle deficits found in individuals with mTBI. Objectives: Based on the limited literature and clinical evidence describing traditional and current tests for measuring cognitive-communication deficits (CCD) of TBI, the strengths and weaknesses of the instruments are discussed relative to their use with mTBI. It is necessary to understand the nature and severity of CCD associated with mTBI for treatment planning and goal setting. Yet, the complexity of mTBI sustained in combat, which often co-occurs with PTSD and other psychological health and physiological issues, creates a clinical challenge for speech-language pathologists worldwide. The purpose of the paper is to explore methods for substantiating the nature and severity of CCD described by service members returning from combat. Methods: To better understand the nature of the functional cognitive-communication deficits described by service members returning from combat, a patient questionnaire and a test protocol were designed and administered to over 200 patients. Preliminary impressions are described addressing the nature of the deficits and the challenges faced in differentiating the etiologies of the CCD. Conclusions: Speech-language pathologists are challenged with evaluating, diagnosing, and treating the cognitive-communication deficits of mTBI resulting from combat-related injuries. Assessments that are sensitive to the functional deficits of mTBI are recommended. An interdisciplinary rehabilitation model is essential for differentially diagnosing the consequences of mTBI, PTSD, and other psychological and physical health concerns.
