Summary: Mild traumatic brain injury (mTBI) is a growing burden worldwide, accounting for approximately 80% of all TBI cases. In recent years, candidate biomarkers have been investigated to improve the management of mTBI patients. Blood biomarker measurement in the acute phase after a traumatic event helps reduce unnecessary CT scans and hospitalizations. S100B protein has emerged as the most widely studied and used biomarker for clinical decision making in patients with mTBI. Besides its diagnostic use, S100B plays a role in the molecular pathogenic processes accompanying acute brain injury, making it a potential therapeutic target.

Summary: This study aimed to investigate plasma phosphorylated tau (p-tau181) protein in mild traumatic brain injury (mTBI) patients and concussed athletes. The study found that plasma p-tau181 concentrations were significantly elevated within 48 hours of injury in both groups, with the highest levels observed in patients with neuroimaging evidence of injury. These findings suggest that plasma p-tau181 concentrations may be related to brain injury and could potentially serve as an early diagnostic biomarker for mTBI/concussions.

Summary: This study demonstrates altered cytokine profiles and endotoxin responses in children with traumatic brain injury (TBI), including mild TBI. Children with mild TBI showed decreased levels of IL-8, IL-10, IL-17A, and TNF-alpha compared to controls, along with increased levels of IFN-gamma. In severe TBI, there was no significant IL-6 response to endotoxin, but an increase in IL-17A. These findings suggest immune dysfunction following TBI, especially in mild cases.

Summary: This study found that sports-related concussions (SRC) can affect postural control and motor learning in athletes, leading to persistent symptoms such as neck and shoulder pain, headache, imbalance, dizziness, and visual disturbances. Athletes with persistent post-concussive symptoms (PPCS) at least 6 months after the incident used more energy during balance perturbations and quiet stance, and had diminished sensorimotor adaptation compared to controls.

Summary: This study evaluated the efficacy of self-administered plasticity-based cognitive training for individuals with a history of mild traumatic brain injury and cognitive impairment. The treatment group showed significant improvement in cognitive function compared to the active control group, with equivalent results in depressive and cognitive symptoms between the two groups.

Summary: The study aimed to investigate changes in regional brain volume after mild traumatic brain injury and their relationship with cognitive deficits. The results showed that individuals with mild traumatic brain injury had reduced brainstem volume and this reduction was significantly associated with cognitive function, especially performance on tests like executive card sorting, forward digit span, and verbal learning.

Summary: This study evaluates post-TBI symptoms and disabilities seven to eight years after mild TBI (mTBI), showing that women and individuals with repeated TBI experience more severe symptoms and functional decline. These findings have implications for clinical practice and research, and should be considered in rehabilitation and follow-up plans.

Summary: This study examined the incidence and healthcare utilization of mild traumatic brain injury (mTBI) in young children presenting to U.S. emergency departments. The findings showed that early childhood mTBI is prevalent and results in a significant financial burden. There is wide variation in diagnostic coding and treatment strategies among emergency departments, highlighting the need for further research.

Summary: Childhood mTBI is associated with an increased risk of developing social problems, possibly due to changes in the structural development of the social brain. This study used data from the ABCD Study to examine the development of social problems and cortical thickness in social brain regions following childhood mTBI. The findings showed different developmental trajectories in social problems between children with and without mTBI, with the mTBI group showing higher levels of social problems. Both groups showed similar decreases in social brain cortical thickness.

Summary: Mild traumatic brain injury (mTBI) is a significant public health concern for children. While most children recover within 1 month after mTBI, 10-30% experience lingering neuropsychiatric or neuropsychological symptoms. Factors associated with prolonged recovery include preinjury mental health concerns, female sex, and family characteristics. Early management includes reassurance and brief rest, while specialized evaluation and multimodal therapies are recommended for symptoms lasting more than 4 weeks.

Summary: This study applied network analysis to investigate post-concussion symptoms after mild traumatic brain injury (mTBI) and found that frustration, blurred vision, and concentration difficulties were central symptoms in two different mTBI samples. These symptoms may play an influential role in the experience and maintenance of post-concussion symptoms.

Summary: Based on a review of the literature, there is limited evidence supporting the use of tDCS for improving cognitive and motor performance in mTBI patients, with only three studies meeting the inclusion criteria. This highlights the urgent need for further research to identify optimal therapeutic brain targets and stimulation parameters.

Summary: This systematic review aimed to synthesize recent literature on the relationship between mild traumatic brain injury (mTBI) and Alzheimer's disease and related dementias (ADRD). Of the eight relevant articles identified, four showed a significant relationship between mTBI and disease outcomes, highlighting the need for future research on this causal relationship. Future studies should standardize definitions and methodologies to produce more reliable and comprehensive results.

Summary: A multidisciplinary observation unit protocol was developed for patients with mild traumatic brain injury in the emergency department. The study found that factors such as GCS score, race, and comorbid cardiac disease predicted discharge home after the observation protocol. The majority of subjects did not require hospital admission, demonstrating the effectiveness of the triage plan.
