Abstract
INTRODUCTION Traumatic brain injury (TBI) results in 2.5 million emergency department (ED) visits per year in the US, with mild traumatic brain injury (mTBI) accounting for 90% of cases. There is considerable evidence that many experience chronic symptoms months to years later. This population is rarely represented in interventional studies. Management of adult mTBI in the ED has remained unchanged, without consensus of therapeutic options. The aim of this review was to synthesize existing literature of patient-centered ED treatments for adults who sustain an mTBI, and to identify practices that may offer promise. METHODS A systematic review was conducted using the PubMed and Cochrane databases, while following PRISMA guidelines. Studies describing pediatric patients, moderate to severe TBI, or interventions outside the ED were excluded. Two reviewers independently performed title and abstract screening. A third blinded reviewer resolved discrepancies. The Mixed Methods Appraisal Tool (MMAT) was employed to assess the methodological quality of the studies. RESULTS Our search strategy generated 1002 unique titles. 95 articles were selected for full-text screening. The 26 articles chosen for full analysis were grouped into one of the following intervention categories: (1) predictive models for Post-Concussion Syndrome (PCS), (2) discharge instructions, (3) pharmaceutical treatment, (4) clinical protocols, and (5) functional assessment. Studies that implemented a predictive PCS model successfully identified patients at highest risk for PCS. Trials implementing discharge related interventions found the use of video discharge instructions, encouragement of daily light exercise or bed rest, and text messaging did not significantly reduce mTBI symptoms. The use of electronic clinical practice guidelines (eCPG) and longer leaves of absence from work following injury reduced symptoms. Ondansetron was shown to reduce nausea in mTBI patients. Studies implementing ED Observation Units found significant declines in inpatient admissions and length of hospital stay. The use of tablet-based tasks was found to be superior to many standard cognitive assessments. CONCLUSION Validated instruments are available to aid clinicians in identifying patients at risk for PCS or serious cognitive impairment. EDOU management and evidence-based modifications to discharge instructions may improve mTBI outcomes. Additional research is needed to establish the therapeutic value of medications and lifestyle changes for the treatment of mTBI in the ED.

Abstract
SIGNIFICANCE Photosensitivity is common after mild traumatic brain injury. However, this study demonstrates that photosensitivity is also impacted by common comorbidities that often occur with mild traumatic brain injury. Understanding how physical and psychological traumas impact photosensitivity can help improve provider care to trauma survivors and guide novel therapeutic interventions. PURPOSE This study aimed to characterize the association between mild traumatic brain injury and common comorbidities on photosensitivity in post-9/11 veterans. METHODS Existing data from the Translational Research Center for TBI and Stress Disorders cohort study were analyzed including traumatic brain injury history and post-traumatic stress disorder clinical diagnostic interviews; sleep quality, anxiety, and depression symptoms self-report questionnaires; and photosensitivity severity self-report from the Neurobehavioral Symptom Inventory. Analysis of covariance and multiple ordinal regression models were used to assess associations between mild traumatic brain injury and common comorbidities with photosensitivity severity. RESULTS Six hundred forty-one post-9/11 veterans were included in this study. An initial analysis showed that both mild traumatic brain injury and current post-traumatic stress disorder diagnosis were independently associated with higher photosensitivity ratings compared with veterans without either condition, with no interaction observed between these two conditions. Results of the ordinal regression models demonstrated positive associations between degree of photosensitivity and the number of mild traumatic brain injuries during military service and current post-traumatic stress disorder symptom severity, particularly hyperarousal symptoms, even when controlling for other factors. In addition, the degree of sleep disturbances and current anxiety symptoms were both positively associated with photosensitivity ratings, whereas depression symptoms, age, and sex were not. CONCLUSIONS Repetitive mild traumatic brain injury, post-traumatic stress disorder, anxiety, and sleep disturbances were all found to significantly impact photosensitivity severity and are therefore important clinical factors that eye care providers should consider when managing veterans with a history of deployment-related trauma reporting photosensitivity symptoms.

Abstract
This study investigated the prevalence of lifetime concussions, related psychosocial problems, and post-concussion recovery rates in a clinical sample of children and youth. Participants were 24,186 children and youth (M = 11.9 years, SD = 3.5) who completed an interRAI Child and Youth Mental Health Assessment at mental health agencies across Ontario, Canada. In addition to the expected physiological correlates, results found concussions to be more prevalent in children and youth with attention deficit hyperactivity disorders, anxiety disorders, disruptive behaviour disorders, mood disorders, and those involved in self-harm, harm to others, destructive aggression, and internalizing and externalizing symptoms. The results of this study add to our understanding of children and youth's experiences with concussions. Clinical implications and recommendations are discussed to maximize the effectiveness of evidence-based interventions related to concussion recovery.

Abstract
OBJECTIVE Following sport-related concussion (SRC), early studies have demonstrated racial differences in time to clinical recovery; however, these differences have not been fully explained. We sought to further explore these associations by considering possible mediating/moderating factors. METHODS Data from patients aged 12-18 years diagnosed with SRC from November 2017 to October 2020 were analyzed. Those missing key data, lost to follow-up, or missing race were excluded. The exposure of interest was race, dichotomized as Black/White. The primary outcome was time to clinical recovery (days from injury until the patient was either deemed recovered by an SRC provider or symptom score returned to baseline or zero.) RESULTS: A total of 389 (82%) White and 87 (18%) Black athletes with SRC were included. Black athletes more frequently reported no SRC history (83% vs. 67%, P = 0.006) and lower symptom burden at presentation (median total Post-Concussion Symptom Scale 11 vs. 23, P < 0.001) than White athletes. Black athletes achieved earlier clinical recovery (hazard ratio [HR] = 1.35, 95% CI 1.03-1.77, P = 0.030), which remained significant (HR = 1.32, 95% CI 1.002-1.73, P = 0.048) after adjusting for confounders associated with recovery but not race. A third model adding the initial Post-Concussion Symptom Scale score nullified the association between race/recovery (HR = 1.12, 95% CI 0.85-1.48, P = 0.410). Adding prior concussion history further reduced the association between race/recovery (HR = 1.01, 95% CI 0.77-1.34, P = 0.925). CONCLUSIONS Overall, Black athletes initially presented with fewer concussion symptoms than White athletes, despite no difference in time to clinic. Black athletes achieved earlier clinical recovery following SRC, a difference explained by differences in initial symptom burden and self-reported concussion history. These crucial differences may stem from cultural/psychologic/organic factors.

Abstract
Mild traumatic brain injury (mTBI) is a common problem. Depending on diagnostic criteria, 13 to 62% of those patients develop persistent post-concussion symptoms (PPCS). The main objective of this prospective multi-center study is to derive and validate a clinical decision rule (CDR) for the early prediction of PPCS. Patients aged ≥14 years were included if they presented to one of our seven participating emergency departments (EDs) within 24 h of an mTBI. Clinical data were collected in the ED, and symptom evolution was assessed at 7, 30 and 90 days post-injury using the Rivermead Post-Concussion Questionnaire (RPQ). The primary outcome was PPCS at 90 days after mTBI. A predictive model called the Post-Concussion Symptoms Rule (PoCS Rule) was developed using the methodological standards for CDR. Of the 1083 analyzed patients (471 and 612 for the derivation and validation cohorts, respectively), 15.6% had PPCS. The final model included the following factors assessed in the ED: age, sex, history of prior TBI or mental health disorder, headache in ED, cervical sprain and hemorrhage on computed tomography. The 7-day follow-up identified additional risk factors: headaches, sleep disturbance, fatigue, sensitivity to light, and RPQ ≥21. The PoCS Rule had a sensitivity of 91.4% and 89.6%, a specificity of 53.8% and 44.7% and a negative predictive value of 97.2% and 95.8% in the derivation and validation cohorts, respectively. The PoCS Rule will help emergency physicians quickly stratify the risk of PPCS in mTBI patients and better plan post-discharge resources.

Abstract
Traumatic brain injury (TBI) represents a major public health concern. Although the majority of individuals that suffer mild-moderate TBI recover relatively quickly, a substantial subset of individuals experiences prolonged and debilitating symptoms. An exacerbated response to physiological and psychological stressors after TBI may mediate poor functional recovery. Individuals with TBI can suffer from poor stress tolerance, impairments in the ability to evaluate stressors, and poor initiation (and cessation) of neuroendocrine stress responses, all of which can exacerbate TBI-mediated dysfunction. Here, we pay tribute to the pioneering neuroendocrinologist Dr. Bruce McEwen by discussing the ways in which his work on stress physiology and allostatic loading impacts the TBI patient population both before and after their injuries. Specifically, we will discuss the modulatory role of hypothalamic-pituitary-adrenal axis responses immediately after TBI and later in recovery. We will also consider the impact of stressors and stress responses in promoting post-concussive syndrome and post-traumatic stress disorders, two common sequelae of TBI. Finally, we will explore the role of early life stressors, prior to brain injuries, as modulators of injury outcomes.

Use of Novel Concussion Protocol With Infralow Frequency Neuromodulation Demonstrates Significant Treatment Response in Patients With Persistent Postconcussion Symptoms, a Retrospective Study. Front Hum Neurosci 2022; 16:894758. [PMID: 35685335 PMCID: PMC9170890 DOI: 10.3389/fnhum.2022.894758] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Accepted: 04/20/2022] [Indexed: 01/28/2023] Open
Abstract
Introduction Concussion is a growing public health concern. No uniformly established therapy exists; neurofeedback studies report treatment value. We use infralow frequency neuromodulation (ILF) to remediate disabling neurological symptoms caused by traumatic brain injury (TBI) and noted improved outcomes with a novel concussion protocol. Postconcussion symptoms (PCS) and persistent postconcussion symptoms (PPCS; >3 months post head injury) are designated timelines for protracted neurological complaints following TBI. We performed a retrospective study to explore effectiveness of ILF in PCS/PPCS and investigated the value of using this concussion protocol. Method Patients with PCS/PPCS seen for their first neurology office visit or received their first neurofeedback session between 1 August 2018 and 31 January 2021 were entered. Outcomes were compared following treatment as usual (TAU) vs. TAU with ILF neurotherapy (TAU+ILF). The study cohort was limited to PPCS patients; the TAU+ILF group was restricted further to PPCS patients receiving at least 10 neurotherapy sessions. Within the TAU+ILF group, comparisons were made between those who trained at least 10 sessions using concussion protocol (TAU+ILF+CP) and those who trained for at least 10 sessions of ILF regardless of protocol (TAU+ILF-CP). Results Among our resultant PPCS cohort (n = 59) leading persistent neurological complaints were headache (67.8%), memory impairment (57.6%), and brain fog (50.8%). PPCS patients in TAU+ILF+CP (n = 25) demonstrated greater net (p = 0.004) and percent (p = 0.026) improvement of symptoms compared to PPCS subjects in TAU (n = 26). PPCS patients in TAU+ILF-CP (n = 8) trended toward significant symptom improvements compared to TAU, and TAU+ILF+CP trended toward greater efficacy than TAU+ILF-CP. Conclusion PPCS patients who received TAU+ILF+CP demonstrated significantly greater improvement as a group when compared to TAU. When used as an integrative modality to treatment as usual in managing patients with PPCS, ILF neuromodulation with use of concussion protocol provided significant symptom improvements.

Abstract
BACKGROUND The ability to perform visually-guided motor tasks requires the transformation of visual information into programmed motor outputs. When the guiding visual information does not align spatially with the motor output, the brain processes rules to integrate somatosensory information into an appropriate motor response. Performance on such rule-based, "cognitive-motor integration" tasks is affected in concussion. Here, we investigate the relationship between visuomotor skill performance, concussion history, and sex during the course of a post-concussion management program. METHODS Fifteen acutely concussed working-aged adults, 11 adults with a history of concussion, and 17 healthy controls all completed a recovery program over the course of 4 weeks. Prior to, mid-way, and following the program, all participants were tested on their visuomotor skills. RESULTS We observed an overall change in visuomotor behaviour in all groups, as participants completed the tasks faster and more accurately. Specifically, we observed significant visuomotor skill improvement between the first and final sessions in participants with a concussion history compared to no-concussion-history controls. Notably, we observed a stronger recovery of these skills in females. CONCLUSIONS Our findings indicate that (1) concussion impairs visuomotor skill performance, (2) the performance of complex, rule-based tasks showed improvement over the course of a recovery program, and (3) stronger recovery in females suggests sex-related differences in the brain networks controlling skilled performance, and the effect of injury on these networks.

Abstract
OBJECTIVE Examine pre-existing learning disorders (LD) and attention deficit/hyperactivity disorders (ADHD) as risk factors for prolonged recovery and increased symptomology following pediatric mild traumatic brain injury (mTBI). METHODS We conducted a retrospective cohort study of children/adolescents (5-17 years) with mTBI who presented to a Children's Minnesota Concussion Clinic between April 2018 and March 2019. Differences across strata of pre-existing conditions (present vs. absent) in time to recovery measures were estimated via Kaplan-Meier and Cox proportional hazards analyses and differences in symptom trajectories were examined via linear mixed-effects regression models. Regression models were adjusted for age, sex and other confounders. RESULTS In our cohort of 680 mTBI patients, those with LD (n = 70) or ADHD (n = 107) experienced significantly longer median durations of symptoms (58 and 68 days, respectively) than those without (43 days). Accordingly, LD was significantly associated with delayed symptom recovery (adjusted hazard ratio (aHR) = 1.63, 95% CI: 1.16-2.29), return to school (1.47, 1.08-2.00), and return to physical activity (1.50, 1.10-2.04). Likewise, ADHD was associated with delayed recovery (1.69, 1.28-2.23), return to school (1.52, 1.17-1.97) and physical activity (1.55, 1.19-2.01). Further, patients with LD or ADHD reported, on average, significantly more concussion symptoms and higher vision symptom scores throughout recovery versus those without. There was no evidence that concussion or vision symptom recovery trajectories varied over time between those with/without LD or ADHD (joint P-interactions > 0.05). CONCLUSION Pre-existing LD and ADHD are risk factors for prolonged and more symptomatic mTBI recovery in youth. These results can inform clinical concussion management and recovery expectations.

Abstract
OBJECTIVES Predicting diagnosis and prognosis of traumatic brain injury (TBI) at the prehospital stage is challenging; however, using comprehensive prehospital information and machine learning may improve the performance of the predictive model. We developed and tested predictive models for TBI that use machine learning algorithms using information that can be obtained in the prehospital stage. DESIGN This was a multicentre retrospective study. SETTING AND PARTICIPANTS This study was conducted at three tertiary academic emergency departments (EDs) located in an urban area of South Korea. The data from adult patients with severe trauma who were assessed by emergency medical service providers and transported to three participating hospitals between 2014 to 2018 were analysed. RESULTS We developed and tested five machine learning algorithms-logistic regression analyses, extreme gradient boosting, support vector machine, random forest and elastic net (EN)-to predict TBI, TBI with intracranial haemorrhage or injury (TBI-I), TBI with ED or admission result of admission or transferred (TBI with non-discharge (TBI-ND)) and TBI with ED or admission result of death (TBI-D). A total of 1169 patients were included in the final analysis, and the proportions of TBI, TBI-I, TBI-ND and TBI-D were 24.0%, 21.5%, 21.3% and 3.7%, respectively. The EN model yielded an area under receiver-operator curve of 0.799 for TBI, 0.844 for TBI-I, 0.811 for TBI-ND and 0.871 for TBI-D. The EN model also yielded the highest specificity and significant reclassification improvement. Variables related to loss of consciousness, Glasgow Coma Scale and light reflex were the three most important variables to predict all outcomes. CONCLUSION Our results inform the diagnosis and prognosis of TBI. Machine learning models resulted in significant performance improvement over that with logistic regression analyses, and the best performing model was EN.

OBJECTIVE To determine whether scores obtained from Patient Health Questionnaire-9 (PHQ-9) or the General Anxiety Disorder-7 (GAD-7) instruments administered following a concussion can be used to predict recovery time. METHOD Retrospective cohort study in a university-based specialty concussion center of 502 concussed participants. Participants completed a PHQ-9 and GAD-7 during their initial visit and subsequent visits during the recovery period (ie, at 14, 28, 56, and 84 days). RESULTS The median recovery time from a concussion was 21 days from the initial clinical evaluation; however, individuals with a PHQ-9 score ≤ 6 (n = 262) had a median recovery time of 17 (95% confidence interval [CI] 15-19) days, whereas those with PHQ-9 scores >6 (n = 240) had a median recovery time of 33 (95% CI 28-37) days and a hazard ratio of 0.525 (95% CI 0.438-0.629, P < 0.0001). For individuals with a GAD-7 score ≤ 4 (n = 259), the median recovery was 19 (95% CI 17-21), days whereas for those with a GAD-7 score > 4 (n = 243), the median recovery was 32 (95% CI 28-36) days with a hazard ratio of 0.554 (95% CI 0.462-0.664, P < 0.00). CONCLUSIONS Scores obtained from PHQ-9 and GAD-7 screening tools appear to be predictive of an individual's recovery and may help identify those subjects who may benefit from early psychological interventions.

Trajectories of Persistent Postconcussion Symptoms and Factors Associated with Symptom Reporting after Mild Traumatic Brain Injury. Arch Phys Med Rehabil 2021; 103:313-322. [PMID: 34695386 DOI: 10.1016/j.apmr.2021.09.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 09/16/2021] [Accepted: 09/29/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To examine the trajectories of persistent postconcussion symptoms (PPCS) after mild traumatic brain injury (MTBI) and to investigate which injury-related and personal factors are associated with symptom reporting. DESIGN Prospective longitudinal cohort study. Follow-up at 3 and 12 months postinjury. SETTING A level 1 trauma center and an emergency outpatient clinic. PARTICIPANTS Patients with MTBI (n=358), trauma controls (n=75), and community controls (n=78). MAIN OUTCOME MEASURES Symptoms were assessed with the British Columbia Postconcussion Symptom Inventory. Participants were categorized as having moderate to severe PPCS (msPPCS) when reporting ≥3 moderate/severe symptoms or a BC-PSI total score of ≥13. BC-PSI total scores were compared between the groups and were further used to create cut-offs for reliable change by identifying uncommon and very uncommon change in symptoms in the community control group. Associations between symptom reporting and 25 injury-related and personal factors were examined. RESULTS The MTBI group had a similar prevalence of msPPCS at 3 and 12 months (21%), and reported more symptoms than the control groups. Analyses of individual trajectories, however, revealed considerable change in both msPPCS and BC-PSI total scores in the MTBI group, where both worsening and improvement was common. Intracranial lesions on CT were associated with a greater likelihood of improving from 3 to 12 months. Those with msPPCS at both assessments were more likely to be women and to have these personal preinjury factors: reduced employment, pain, poor sleep, low resilience, high neuroticism and pessimism, and a psychiatric history. CONCLUSIONS Group analyses suggest a stable prevalence of msPPCS the first year postinjury. However, there was considerable intra-individual change. Several personal factors were associated with maintaining symptoms throughout the first year.

Abstract
OBJECTIVE To describe changes in the prevalence and clinical correlates of noise sensitivity (NS) in mild traumatic brain injury (mTBI) across a 12-month period and to determine whether NS at an early stage of recovery has predictive value for later postconcussive symptoms. SETTING A mixed urban and rural region of New Zealand. PARTICIPANTS Data for 341 adults (201 males, 140 females; age range from 16 to 91 years) were extracted from a 1-year TBI incidence, and outcomes study was conducted in New Zealand. DESIGN Secondary analysis of data from a community-based, longitudinal population study of an mTBI incidence cohort collected within 1 week of injury (baseline) and at 1, 6, and 12 months postinjury. MAIN MEASURES Measures at baseline (within 2 weeks of the injury) and 1, 6, and 12 months included the Rivermead Post-concussion Symptoms Questionnaire and its NS item, the Hospital Depression and Anxiety Scale, and the computerized CNS-Vital Signs neurocognitive test. RESULTS NS progressively declined postinjury, from 45% at baseline to 28% at 12 months. In turn, NS showed itself as a significant predictor of future postconcussive symptoms. CONCLUSION Taken together with previous research, the findings of the current study indicate that NS may have clinical utility in flagging vulnerability to persistent postconcussive symptoms.

Abstract
SIGNIFICANCE This study reports the prevalence and relative risk of photophobia in patients with traumatic brain injury (TBI). OBJECTIVES This study aimed to conduct a systematic review and meta-analysis to determine the prevalence and relative risk of photophobia in patients with TBI. DATA SOURCES Three databases were used for literature search: PubMed, EMBASE, and Cochrane Library. STUDY APPRAISAL AND SYNTHESIS METHODS Publications reporting the prevalence of photophobia after TBI in patients of any age were included. A series of meta-regression analyses based on a generalized linear mixed model was performed to identify potential sources of heterogeneity in the prevalence estimates. RESULTS Seventy-five eligible publications were identified. The prevalence of photophobia was 30.46% (95% confidence interval [CI], 20.05 to 40.88%) at 1 week after the injury. Prevalence decreased to 19.34% (95% CI, 10.40 to 28.27%) between 1 week and 1 month after TBI and to 13.51% (95% CI, 5.77 to 21.24%) between 1 and 3 months after the injury. The rapid decrease in the prevalence of photophobia in the first 3 months after a TBI injury was significant (P < .001). Three months post-TBI, the prevalence of photophobia leveled off to a near plateau with nonsignificant variability, increasing between 3 and 6 months (17.68%; 95% CI, 9.05 to 26.32%) and decreasing between 6 and 12 months since TBI (14.85%; 95% CI, 6.80 to 22.90%). Subgroup analysis of 14 publications that contained control data showed that the estimated risk ratio for photophobia was significantly higher in the TBI than in the control group during the entire 12 months after TBI. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS This study demonstrates that photophobia is a frequent complaint after TBI, which largely resolves for many individuals within 3 months after the injury. For some patients, however, photophobia can last up to 12 months and possibly longer. Developing an objective quantitative methodology for measuring photophobia, validating a dedicated photophobia questionnaire, and having a specific photophobia International Classification of Diseases, Tenth Revision code would greatly improve data gathering and analysis.

Abstract
Objective: To present pre-injury, injury-related, work-related and post-injury characteristics, and to compare patients with and without traumatic intracranial abnormalities, in a treatment-seeking sample with persistent post-concussion symptoms (PPCS) after mild-to-moderate TBI.Methods: Cross-sectional design in the context of a specialized TBI outpatient clinic. Eligible patients were aged 18-60 years, employed ≥ 50% at time of injury, and sick listed ≥ 50% at inclusion due to PPCS. Data were collected 8-12 weeks after injury through review of medical records, semi-structured interviews, questionnaires, and neuropsychological screening.Results: The study included 116 patients, of whom 60% were women, and predominantly white-collar workers in full-time positions. Ninety-four percent had a mild TBI, and 23% had intracranial abnormalities. The full sample reported high somatic, emotional, and cognitive symptom burden, and decreased health-related quality of life. Patients with normal CT/MRI results reported higher overall symptom burden, while patients with intracranial abnormalities had worse memory function.Conclusion: Injury severity and traumatic intracranial radiological findings should not be the sole ground for planning of rehabilitation service provision in patients with PPCS, as subjective complaints do not necessarily co-vary with these variables.

Abstract
OBJECTIVE To assess photophobia and allodynia in subjects with post-traumatic headache and examine how these sensory hypersensitivities associate with clinical measures of disease burden. BACKGROUND Post-traumatic headache is the most frequent and disabling long-term consequence of mild traumatic brain injury. There is evidence of sensory dysfunction in acute post-traumatic headache, and it is known from other headache conditions that sensory amplifications correlate with more severe disease. However, systematic studies in post-traumatic headache are surprisingly scarce. METHODS We tested light and tactile sensitivity, along with measures of disease burden, in 30 persistent post-traumatic headache subjects and 35 controls. RESULTS In all, 79% of post-traumatic headache subjects exhibited sensory hypersensitivity based on psychophysical assessment. Of those exhibiting hypersensitivity, 54% exhibited both light and tactile sensitivity. Finally, sensory thresholds were correlated across modalities, as well as with headache attack frequency. CONCLUSIONS In this study, post-traumatic headache subjects with both light and tactile sensitivity had significantly higher headache frequencies and lower sensitivity thresholds to both modalities, compared to those with single or no sensory hypersensitivity. This pattern suggests that hypersensitivity across multiple modalities may be functionally synergistic, reflect a higher disease burden, and may serve as candidate markers of disease.

Abstract
PURPOSE To describe and explore the relationship between baseline anxiety, depression and symptom experience in children and youth assessed at a concussion clinic. DESIGN AND METHODS A retrospective chart review of concussed children and youth referred to a pediatric teaching hospital concussion clinic over a 15-month period was completed. Kutcher Adolescent Depression Scale (KAD-6), General Anxiety Disorder Scale (GAD-7), and the Post-Concussion Symptom Inventory (PCSI) scores were extracted. RESULTS A total of 155 patients were included. The most common symptoms (PCSI) at baseline were headache, fatigue, and feelings of head pressure. Symptoms were rated as mild to moderate in intensity. Overall, mean depression and anxiety scores were low. The mean anxiety scores, as measured by the GAD-7 (n = 108), was 7.4 (range, 0-24). The mean depression score, as measured by the KAD-6 (n = 94), was 4.7 (range, 0-18). A statistically significant, moderate positive correlation between PCSI scores with KAD-6 scores for male (r = .64, p < .001) and female (r = .61, p < .001) participants was identified. Similarly, a statistically significant, moderate positive correlation between PCSI scores with GAD-7 scores for male (r = .68, p < .001) and female (r = .60, p < .001) participants was identified. PRACTICE IMPLICATIONS Concussed children may experience a wide array of symptoms, including emotional challenges such as anxiety and depression. Feelings of anxiety and depression may contribute to overall post concussive symptoms in concussed children. The electronic health record can be leveraged to provide important patient data. Clinicians should systematically assess symptoms at each visit in concussed children and youth so that appropriate interventions can be implemented and monitored.

Abstract
Introduction Traumatic brain injury is a leading cause of death and disability globally with an estimated African incidence of approximately 8 million cases annually. A person suffering from a TBI is often aged 20–30, contributing to sustained disability and large negative economic impacts of TBI. Effective emergency care has the potential to decrease morbidity from this multisystem trauma. Objectives Identify and summarize key recommendations for emergency care of patients with traumatic brain injuries using a resource tiered framework. Methods A literature review was conducted on clinical care of brain-injured patients in resource-limited settings, with a focus on the first 48 h of injury. Using the AfJEM resource tiered review and PRISMA guidelines, articles were identified and used to describe best practice care and management of the brain-injured patient in resource-limited settings. Key recommendations Optimal management of the brain-injured patient begins with early and appropriate triage. A complete history and physical can identify high-risk patients who present with mild or moderate TBI. Clinical decision rules can aid in the identification of low-risk patients who require no neuroimaging or only a brief period of observation. The management of the severely brain-injured patient requires a systematic approach focused on the avoidance of secondary injury, including hypotension, hypoxia, and hypoglycaemia. Most interventions to prevent secondary injury can be implemented at all facility levels. Urgent neuroimaging is recommended for patients with severe TBI followed by consultation with a neurosurgeon and transfer to an intensive care unit. The high incidence and poor outcomes of traumatic brain injury in Africa make this subject an important focus for future research and intervention to further guide optimal clinical care.

Abstract
This longitudinal study aimed to evaluate qualitative (parosmia) and quantitative (hyposmia/anosmia) olfaction 2-4 weeks (baseline) and six months (follow-up) after a mild traumatic brain injury (mTBI). We further evaluated the predictive value of baseline depression, anxiety and olfaction scores on depression and anxiety at follow-up. At baseline, olfactory function and affective state were assessed in 107 participants (53 patients with mild TBI; 54 healthy controls). At follow-up, data were collected on 71 participants (32 patients, 39 controls). Both at baseline and follow-up, patients with mild TBI showed more signs of parosmia, depression and anxiety, compared to controls. However, patients did not, neither at baseline nor follow-up, show quantitative olfactory impairment. Moreover, while baseline scores of depression and anxiety helped predict the development of symptoms of depression and anxiety at follow up, adding parosmia scores to the prediction model significantly increased the amount of explained variances. Clinicians should implement affective and olfactory evaluation to predict patients' affective outcome.

Abstract
AbstractOur purpose was to evaluate the effect of self-reported pre-injury anxiety
diagnosis on persistent symptom development, vestibular symptom severity, and
balance control among youth who sustained a concussion. We performed a
retrospective study of patients seen at a specialty pediatric concussion clinic.
Patients were 18 years of age or younger, examined within 10 days of concussion,
and received care until full recovery. A questionnaire was used to assess
pre-existing medical and psychiatric conditions, including anxiety. Our main
outcomes were prolonged symptom recovery defined as persistent symptoms for
> 28 days after concussion) and severity of vestibular symptoms.
Patients who reported pre-injury anxiety (n=43; median age=14.9
years; 37% female) were more likely to experience symptoms>28
days post-injury (76 vs. 54%; p=0.04) than those without
pre-existing anxiety (n=241; median age=14.9 years; 53%
female). After adjusting for sex, history of migraine, depression and ADHD,
however, there was no independent association between pre-existing anxiety and
prolonged symptom duration (adjusted odds ratio=2.34; 95%
CI=0.083–6.63; p=0.11). Pre-existing anxiety was
independently associated with self-reported nausea/vomiting severity
(β coefficient=0.59, 95% CI=0.07–1.11).
A pre-existing anxiety diagnosis does not appear to be associated with
persistent symptoms after concussion, although it may be associated with
post-injury nausea.

Towards the Development of an Integrative, Evidence-Based Suite of Indicators for the Prediction of Outcome Following Mild Traumatic Brain Injury: Results from a Pilot Study. Brain Sci 2020; 10:brainsci10010023. [PMID: 31906443 PMCID: PMC7017246 DOI: 10.3390/brainsci10010023] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 12/16/2019] [Accepted: 12/30/2019] [Indexed: 12/14/2022] Open
Abstract
Background: Persisting post-concussion symptoms (PPCS) is a complex, multifaceted condition in which individuals continue to experience the symptoms of mild traumatic brain injury (mTBI; concussion) beyond the timeframe that it typically takes to recover. Currently, there is no way of knowing which individuals may develop this condition. Method: Patients presenting to a hospital emergency department (ED) within 48 h of sustaining a mTBI underwent neuropsychological assessment and demographic, injury-related information and blood samples were collected. Concentrations of blood-based biomarkers neuron specific enolase, neurofilament protein-light, and glial fibrillary acidic protein were assessed, and a subset of patients also underwent diffusion tensor–magnetic resonance imaging; both relative to healthy controls. Individuals were classified as having PPCS if they reported a score of 25 or higher on the Rivermead Postconcussion Symptoms Questionnaire at ~28 days post-injury. Univariate exact logistic regression was performed to identify measures that may be predictive of PPCS. Neuroimaging data were examined for differences in fractional anisotropy (FA) and mean diffusivity in regions of interest. Results: Of n = 36 individuals, three (8.33%) were classified as having PPCS. Increased performance on the Repeatable Battery for the Assessment of Neuropsychological Status Update Total Score (OR = 0.81, 95% CI: 0.61–0.95, p = 0.004), Immediate Memory (OR = 0.79, 95% CI: 0.56–0.94, p = 0.001), and Attention (OR = 0.86, 95% CI: 0.71–0.97, p = 0.007) indices, as well as faster completion of the Trails Making Test B (OR = 1.06, 95% CI: 1.00–1.12, p = 0.032) at ED presentation were associated with a statistically significant decreased odds of an individual being classified as having PPCS. There was no significant association between blood-based biomarkers and PPCS in this small sample, although glial fibrillary acidic protein (GFAP) was significantly increased in individuals with mTBI relative to healthy controls. Furthermore, relative to healthy age and sex-matched controls (n = 8), individuals with mTBI (n = 14) had higher levels of FA within the left inferior frontal occipital fasciculus (t (18.06) = −3.01, p = 0.008). Conclusion: Performance on neuropsychological measures may be useful for predicting PPCS, but further investigation is required to elucidate the utility of this and other potential predictors.

The association between health-related quality of life and noise or light sensitivity in survivors of a mild traumatic brain injury. Qual Life Res 2019; 29:665-672.

Abstract
PURPOSE Sensory impairment is a common aftereffect of mild traumatic brain injury (TBI); however, their influence upon treatment outcomes and quality of life has yet to be investigated. This study sought to determine the effects of noise and light sensitivity upon the quality of life of individuals diagnosed with a TBI. METHODS A cross-sectional adult sample obtained from a longitudinal study (n = 293) provided measures of light and noise sensitivity and quality of life 12 months post injury. Sensitivities were taken from the Rivermead Post-concussion Symptoms Questionnaire, while quality of life was estimated using the Short-Form 36 health survey (SF-36). RESULTS Approximately 42% of participants reported ongoing difficulties with noise and light sensitivity. Additionally, those reporting sensory difficulties also reported lower SF-36 domain and composite scores compared to those reporting no such symptoms. After controlling for known co-factors, hierarchical multiple regression analyses indicated that the combination of light and noise sensitivity explained between 8 and 35% of the variance in SF-36 scores. CONCLUSIONS Light and noise sensitivity appear to degrade the quality of life of those with a mild TBI. Our findings challenge contemporary rehabilitation practices that tend to sideline sensory complaints and instead focus on the remediation of acute TBI symptoms.

Abstract
Liquid crystal display (LCD) screens refresh at a rate of 60 times per second, which can be perceived by concussed individuals who have photosensitivity, leading to computer intolerance. A non-LCD computer screen that refreshes at a much lower rate could relieve this photosensitivity and computer screen intolerance in patients with post-concussion syndrome (PCS). Twenty-nine patients with PCS, computer intolerance, and photosensitivity performed a reading task for a maximum of 30 min, with an LCD computer or a non-LCD device, and were given a comprehension test after completion of the reading task. The Sport Concussion Assessment Tool 3 was administered before and after each reading task. Symptom scores, amount of time spent reading, and performance on the comprehension tests were compared between the two devices. Patients also completed a self-report questionnaire of their subjective experience. The LCD screen computer produced significantly greater symptom exacerbation (median difference = 5, W = 315, p < 0.01) and a greater number of symptoms (median difference = 1, W = 148, p < 0.01) than the non-LCD screens. The non-LCD screen resulted in a longer symptom-free reading time (median = 48 sec, W = 147, p < 0.01), but not a greater number of words read (median = 281, W = 148, p = 0.098). Females were more likely to have greater symptom exacerbation with the LCD screen (U = 14.0, p < 0.01). No significant difference was found in performance on the comprehension test. Subjective reports showed that the non-LCD experience was more favorable, and most patients stated they would recommend this device for other patients with PCS. This study is the first to show the clinical utility of non-LCD screen computers in the management of photosensitivity and computer screen intolerance in patients with PCS. The non-LCD screen computer has the potential to facilitate return-to-work or return-to-school in concussed individuals.

Abstract
Traumatic brain injuries in children represent a major public health issue and even relatively mild injuries can have lifelong consequences. However, the outcomes from these injuries are highly heterogeneous, with most individuals recovering fully, but a substantial subset experiencing prolonged or permanent disabilities across a number of domains. Moreover, brain injuries predispose individuals to other kinds of neuropsychiatric and somatic illnesses. Critically, the severity of the injury only partially predicts subsequent outcomes, thus other factors must be involved. In this review, we discuss the psychological, social, neuroendocrine, and autonomic processes that are disrupted following traumatic brain injury during development, and consider the mechanisms the mediate risk or resilience after traumatic brain injury in this vulnerable population.

Abstract
Traumatic brain injury (TBI) is one of the most common injuries to military personnel, a population often exposed to stressful stimuli and emotional trauma. Changes in sensory processing after TBI might contribute to TBI-post traumatic stress disorder (PTSD) comorbidity. Combining an animal model of TBI with an animal model of emotional trauma, we reveal an interaction between auditory sensitivity after TBI and fear conditioning where 75 dB white noise alone evokes a phonophobia-like phenotype and when paired with footshocks, fear is robustly enhanced. TBI reduced neuronal activity in the hippocampus but increased activity in the ipsilateral lateral amygdala (LA) when exposed to white noise. The white noise effect in LA was driven by increased activity in neurons projecting from ipsilateral auditory thalamus (medial geniculate nucleus). These data suggest that altered sensory processing within subcortical sensory-emotional circuitry after TBI results in neutral stimuli adopting aversive properties with a corresponding impact on facilitating trauma memories and may contribute to TBI-PTSD comorbidity.

Abstract
Headache attributed to traumatic injury to the head (HAIH) is claimed to be the most common sequela following mild traumatic brain injury (MTBI), but epidemiological evidence is scarce. We explored whether patients with MTBI had an increase in headache suffering following injury compared with controls. We also studied predictors of headache. The Trondheim MTBI follow-up study is a population-based, controlled, longitudinal study. We recruited patients exposed to MTBI and controls with minor orthopedic injuries from a trauma center and a municipal outpatient clinic, and community controls from the surrounding population. Information on headache was collected through questionnaires at baseline, and 3 and 12 months post-injury. We used a generalized linear mixed model to investigate the development of headache over time in the three groups, and logistic regression to identify predictors of headache. We included 378 patients exposed to MTBI, 82 trauma controls, and 83 community controls. The MTBI-group had a larger increase in odds of headache from baseline to the first 3 months post-injury than the controls, but not from baseline to 3–12 months post-injury. Predictors for acute HAIH were female sex and pathological imaging findings on computed tomography (CT) or magnetic resonance imaging (MRI). Predictors for persistent HAIH were prior MTBI, being injured under the influence of alcohol, and acute HAIH. Patients who experience HAIH during the first 3 months post-injury have a good chance to improve before 12 months post-injury. Female sex, imaging findings on CT or MRI, prior MTBI, and being injured under the influence of alcohol may predict exacerbation of headache.

Abstract
Concussions have gained attention in medical literature, legal literature, and lay media over the past several years as a public health affecting children, particularly those who do not improve in the first few days after an injury. We discuss strategies for acute management immediately after a concussion and an introduction to medical and non-medical options for treatment of the complex symptoms that persist in some patients with concussions. We examine the role of rest and exercise during recovery. We briefly discuss the role of the multidisciplinary approach to concussion in a setting that engages multiple specialists. Finally, we address policy changes related to sport-concussions and their efficacy in improving long term outcomes.

Abstract
Primary objective: The impact of noise sensitivity (NS) on the daily functioning of people who have experienced a traumatic brain injury (mTBI) is an understudied area, particularly following mTBI. The primary objective of this cross-sectional study was to investigate clinical markers of NS in a sample of New Zealand adults following mTBI. Research design: Cross-sectional study. Methods and procedures: A community-based sample of 151 adults who had experienced a brain injury in the last two weeks completed assessments estimating cognitive functioning, postconcussion symptoms (including NS), and affective state. Results: Over half the sample (59%) reported some degree of NS. Exploratory statistical analyses indicated that NS was associated with being female, living in a rural area, number of previous brain injuries, cognitive flexibility scores, reaction time, perceptions of recovery, anxiety, and depression. Regression analyses revealed that anxiety was the dominant correlate of NS (B = .120, p < .001, 95% CI [0.069, 1.71]). Conclusions: As the first study to explore the correlates of NS following mild TBI, the findings have important clinical and research implications. The present findings suggest that treatment approaches targeting anxiety may be effective in reducing NS in people who have experienced a brain injury. Moreover, evidence is presented suggesting that NS is unlikely to reflect malingering, and should be treated as a genuine somatic symptom of brain injury.

Abstract
OBJECTIVES The Montreal Cognitive Assessement (MoCA) is a brief and standardized cognitive screening tool that has been used with several clinical populations. The aim of this study was to screen the early cognitive status of patients following mild traumatic brain injury (mTBI) with the MoCA. METHODS The MoCA was administered within the first 2 weeks post-injury to 42 patients with uncomplicated mTBI, 92 patients with complicated mTBI and 50 healthy controls. RESULTS Patients with complicated mTBI had a significantly lower performance (more impairments) on the total score of the MoCA than both the group with uncomplicated mTBI and the control group. Also, the group with uncomplicated mTBI had a significantly lower performance than controls. Moreover, age, education and TBI severity had a significant effect on the MoCA total score where younger, more educated and patients with less severe (higher GCS score) mTBI performed significantly better. CONCLUSIONS The MoCA may be clinically useful to acutely screen cognition following mTBI.

Abstract
Sensitivity to sounds is one frequent symptom of a sport-related concussion, but its assessment rarely goes beyond a single question. Here we examined sensitivity to sounds using psychoacoustic and psychometric outcomes in athletes beyond the acute phase of injury. Fifty-eight college athletes with normal hearing who either had incurred one or more sport-related concussions (N = 28) or who had never suffered head injury (N = 30) participated. Results indicated that the Concussed group scored higher on the Hyperacusis questionnaire and displayed greater sensitivity to sounds in psychoacoustic tasks compared to the Control group. However, further analyses that separated the Concussed group in subgroups with Sound sensitivity symptom (N = 14) and Without sound sensitivity symptom (N = 14) revealed that athletes with the sound complaint were the ones responsible for the effect: Concussed athletes with self-reported sound sensitivity had lower Loudness Discomfort Thresholds (LDLs), higher Depression and Hyperacusis scores, and shifted loudness growth functions compared to the other subgroup. A simple mediation model disclosed that LDLs exert their influence both directly on Hyperacusis scores as well as indirectly via depressive symptoms. We thus report a new clinical presentation of hyperacusis and discuss possible mechanisms by which it could arise from concussion.

Mild traumatic brain injury (MTBI) is a common condition within the general population, usually with good clinical outcome. However, in 10-25% of cases, a post-concussive syndrome (PCS) occurs. Identifying early prognostic factors for the development of PCS can ensure widespread clinical and economic benefits. The aim of this study was to demonstrate the potential value of a comprehensive neuropsychological evaluation to identify early prognostic factors following MTBI. We performed a multi-center open, prospective, longitudinal study that included 72 MTBI patients and 42 healthy volunteers matched for age, gender, and socioeconomic status. MTBI patients were evaluated 8-21 days after injury, and 6 months thereafter, with a full neurological and psychological examination and brain MRI. At 6 months follow-up, MTBI patients were categorized into two subgroups according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) as having either favorable or unfavorable evolution (UE), corresponding to the presence of major or mild neurocognitive disorder due to traumatic brain injury. Univariate and multivariate logistical regression analysis demonstrated the importance of patient complaints, quality of life, and cognition in the outcome of MTBI patients, but only 6/23 UE patients were detected early via the multivariate logistic regression model. Using several variables from each of these three categories of variables, we built a model that assigns a score to each patient presuming the possibility of UE. Statistical analyses showed this last model to be reliable and sensitive, allowing early identification of patients at risk of developing PCS with 95.7% sensitivity and 77.6% specificity.

Abstract
Conceptual models for assessing and treating sport-related concussion (SRC) have evolved from a homogenous approach to include different clinical profiles that reflect the heterogeneous nature of this injury and its effects. There are six identified clinical profiles, or subtypes from SRC, and one such clinical profile is the anxiety/mood profile. Athletes with this profile experience predominant emotional disturbance and anxiety following SRC. The purpose of this targeted review was to present an overview of the empirical evidence to support factors contributing to the anxiety/mood profile, along with methods of evaluation and treatment of this clinical profile following SRC. We discuss the potential underlying mechanisms and risk factors for this clinical profile, describe comprehensive assessments to evaluate concussed athletes with an anxiety/mood clinical profile, and explore behavioral and other interventions for treating these athletes. Although there is limited, but growing empirical evidence for the anxiety/mood clinical profile following SRC, understanding this clinical profile is germane for clinicians who are treating athletes with emotional sequelae after SRC.

Abstract
PRIMARY OBJECTIVE To investigate factors that predict discharge recommendations for children and adolescents who present to an Australian paediatric Emergency Department (ED) following a mild traumatic brain injury (mTBI). RESEARCH DESIGN Retrospective data base analysis. METHODS The study retrospectively analysed an ED database to test the relationship between injury risk factors (symptoms, Glasgow Coma Scale, prior TBI, mechanism of injury and Computed Tomography scan), non-injury risk factors (sex, age, socio-economic status (SES)) and discharge recommendations of 2807 children and adolescents (0-18 years) who presented to a children's hospital ED over a three year period with mTBI. RESULTS Univariate analyses indicated a statistically significant association of discharge recommendations with age, SES, mechanism of injury and vomiting. However, multivariate analyses indicated vomiting and mechanism of injury were the only statistically significant risk factor associated with discharge recommendations, when controlling for other risk factors. CONCLUSIONS The current study suggests vomiting and mechanism of injury are the only risk factors predicting discharge recommendations for children and adolescents with mTBI.

Abstract
OBJECTIVE To characterize the psychological factors associated with persistent symptoms after pediatric concussion. STUDY DESIGN Longitudinal cohort study of 179 children with concussion 8-18 years old evaluated in a pediatric emergency department. Participants were followed for 1 month for delayed symptom resolution, defined as ≥3 symptoms that were new/worse than preinjury symptoms measured by the use of graded symptom inventory. Preinjury psychological traits were measured by parental report on subscales of the Personality Inventory for Children-2 (maladjustment, cognitive abilities, somatization). Child report of postinjury anxiety and injury perception were measured with the State-Trait Anxiety Inventory for Children and Children's Illness Perception Questionnaire. Psychological instrument scores were compared between those with and without delayed symptom resolution via a Kruskal-Wallis test. Associations between psychological traits and delayed symptom resolution were investigated by the use of logistic regression. RESULTS Delayed symptom resolution occurred in 21% of participants. Score distributions were significantly worse on the State-Trait Anxiety Inventory for Children (38 [IQR 33-40] vs 35 [IQR 31-39]; P = .04) and somatization subscale (1 [IQR 0-3] vs 1 [IQR 0-1]; P = .01) among children with delayed symptom resolution compared with children with early symptom resolution. Somatization was associated with delayed symptom resolution (aOR 1.35, 95% CI 1.08-1.69). The proportion of children with abnormal somatization scores was significantly greater in the delayed symptom resolution group (34.2%) than the early symptom resolution group (12.8%; P < .01). Other psychological measures were not different between groups. CONCLUSION Somatization is associated with delayed symptom resolution in this cohort of children with concussion. Postconcussive symptoms lasting at least 1 month may warrant referral to a neuropsychologist familiar with postconcussion care.

Abstract
OBJECTIVE Patients who have experienced a mild traumatic brain injury (mTBI) are susceptible to symptoms of anxiety or depression. To explore the potential biomarkers for emotional disorders in mTBI patients, we analyzed the frequency domain of heart rate variability (HRV) and serum concentrations of four neurohormones. METHODS We assessed mTBI patients on their first visit and follow-up. Symptoms were evaluated by the Beck Anxiety Inventory and the Beck Depression Inventory, respectively. Serum levels of adrenocorticotropic hormone (ACTH), melatonin, cortisol, and insulin-like growth factor (IGF)-1 and HRV follow-ups were measured and compared. RESULTS mTBI patients were more vulnerable to symptoms of anxiety or depression than healthy controls. Reduced HRV was noted in mTBI patients compared to healthy controls. The mTBI patients demonstrated higher serum levels of ACTH, lower IGF-1 compared to healthy controls. In correlation analysis, only IGF-1 was positively correlated with HRV in mTBI patients. Both HRV and IGF-1 were correlated with symptom of depression while only HRV was correlated with symptom of anxiety in mTBI patients. CONCLUSIONS We infer that HRV may be more significantly correlated with emotional disorders than is IGF-1 in mTBI patients. SIGNIFICANCE The study is relevant for specific diagnostic markers in mTBI patients.

Abstract
OBJECT Sport-related concussion (SRC) is a major public health problem. Approximately 90% of SRCs in high school athletes are transient; symptoms recover to baseline within 1 week. However, a small percentage of patients remain symptomatic several months after injury, with a condition known as postconcussion syndrome (PCS). The authors aimed to identify risk factors for PCS development in a cohort of exclusively young athletes (9-18 years of age) who sustained SRCs while playing a sport. METHODS The authors conducted a retrospective case-control study by using the Vanderbilt Sports Concussion Clinic database. They identified 40 patients with PCS and matched them by age at injury and sex to SRC control patients (1 PCS to 2 control). PCS patients were those experiencing persistent symptoms at 3 months after an SRC. Control patients were those with documented resolution of symptoms within 3 weeks of an SRC. Data were collected in 4 categories: 1) demographic variables; 2) key medical, psychiatric, and family history; 3) acute-phase postinjury symptoms (at 0-24 hours); and 4) subacute-phase postinjury features (at 0-3 weeks). The chi-square Fisher exact test was used to assess categorical variables, and the Mann-Whitney U-test was used to evaluate continuous variables. Forward stepwise regression models (Pin = 0.05, Pout = 0.10) were used to identify variables associated with PCS. RESULTS PCS patients were more likely than control patients to have a concussion history (p = 0.010), premorbid mood disorders (p = 0.002), other psychiatric illness (p = 0.039), or significant life stressors (p = 0.036). Other factors that increased the likelihood of PCS development were a family history of mood disorders, other psychiatric illness, and migraine. Development of PCS was not predicted by race, insurance status, body mass index, sport, helmet use, medication use, and type of symptom endorsement. A final logistic regression analysis of candidate variables showed PCS to be predicted by a history of concussion (OR 1.8, 95% CI 1.1-2.8, p = 0.016), preinjury mood disorders (OR 17.9, 95% CI 2.9-113.0, p = 0.002), family history of mood disorders (OR 3.1, 95% CI 1.1-8.5, p = 0.026), and delayed symptom onset (OR 20.7, 95% CI 3.2-132.0, p < 0.001). CONCLUSIONS In this age- and sex-matched case-control study of risk factors for PCS among youth with SRC, risk for development of PCS was higher in those with a personal and/or family history of mood disorders, other psychiatric illness, and migraine. These findings highlight the unique nature of SRC in youth. For this population, providers must recognize the value of establishing the baseline health and psychiatric status of children and their primary caregivers with regard to symptom reporting and recovery expectations. In addition, delayed symptom onset was an unexpected but strong risk factor for PCS in this cohort. Delayed symptoms could potentially result in late removal from play, rest, and care by qualified health care professionals. Taken together, these results may help practitioners identify young athletes with concussion who are at a greater danger for PCS and inform larger prospective studies for validation of risk factors from this cohort.
