moderate to serious concussion symptoms

Concussion is a common injury in the adolescent and young adult populations. While branched chain amino acid (BCAA) supplementation has shown improvements in neurocognitive and sleep function in pre-clinical animal models of mild to moderate traumatic brain injury (TBI), to date, no studies have been performed evaluating the efficacy of BCAAs in concussed adolescents and young adults. The goal of this pilot trial was to determine the efficacy, tolerability, and safety of varied doses of oral branched chain amino acid (BCAA) supplementation in a group of concussed adolescents and young adults...

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...

CONTEXT: The influence of several psychological characteristics on the willingness of athletes to report concussion behaviors has not been well explored. Therefore, the purpose of this study was to understand how athletic identity and sport passion predicted participants' willingness to report symptoms above what was explained by athlete demographics, concussion knowledge, and perceived seriousness of concussions. DESIGN: The study was cross-sectional. METHODS: Three-hundred and twenty-two male and female high school and club sport athletes completed survey measures of concussion knowledge, athletic identity, harmonious and obsessive passion, and degree to which athletes indicated they would report concussions and concussion symptoms...

OBJECTIVE: To investigate the utility of melatonin supplementation as a treatment option for individuals with sleep disturbance after traumatic brain injury (TBI). DATA SOURCES: A systematic search was conducted in 6 electronic databases (Medline, AMED, CINAHL, Embase, Scopus, and SPORTDiscus) from earliest records to April 2022. STUDY SELECTION: Studies were eligible for inclusion if they met the following criteria: a) human participants with sleep disturbance after TBI, b) melatonin or melatonergic agent used as an intervention to treat sleep disturbance, and c) outcomes of melatonin administration reported...

BACKGROUND: This study examined the association between sports- or physical activity-related concussions and having seriously considered attempting suicide, made a suicide plan, or attempted suicide (ie, suicidality), and tested potential moderators of the association. HYPOTHESIS: Risk factors such as persistent feelings of sadness or hopelessness, low academic grades, few hours of sleep, and current alcohol or marijuana use will increase the odds of suicidality among those who self-reported sports- or physical activity-related concussions, while protective factors such as physical activity and having played on a sports team will decrease the odds...

CONTEXT: Previous literature on sport-related concussion (SRC) knowledge and reporting behaviors has been limited to high school and National Collegiate Athletic Association collegiate athletes; however, knowledge regarding collegiate club-sport athletes is limited. OBJECTIVE: To determine the level of SRC knowledge and reporting behaviors among collegiate club-sport athletes and to investigate differences between athletes in traditional and nontraditional sports...

Repeated concussion is becoming increasingly recognized as a serious public health concern around the world. Moreover, there is a greater awareness amongst health professionals of the potential for repeated pediatric concussions to detrimentally alter the structure and function of the developing brain. To better study this issue, we developed an awake closed head injury (ACHI) model that enabled repeated concussions to be performed reliably and reproducibly in juvenile rats. A neurological assessment protocol (NAP) score was generated immediately after each ACHI to help quantify the cumulative effects of repeated injury on level of consciousness, and basic motor and reflexive capacity...

BACKGROUND AND PURPOSE: Treatments to facilitate recovery after traumatic brain injury (TBI) are urgently needed. We conducted a 9-month pilot, randomized placebo-controlled clinical trial to examine the safety and potential effects of the herbal supplement MLC901 (NeuroAiD II™) on cognitive functioning following TBI. METHODS: Adults aged 18-65 years at 1-12 months after mild or moderate TBI were randomized to receive MLC901 (0.8 g capsules 3 times daily) or placebo for 6 months...

Traumatic brain injury (TBI) is a serious healthcare problem, and this report is a selective review of recent findings on the epidemiology, pathophysiology and neuropsychological impairments following TBI. Patients who survive moderate-to-severe TBI frequently suffer from a wide range of cognitive deficits and behavioral changes due to diffuse axonal injury. These deficits include slowed information-processing and impaired long-term memory, attention, working memory, executive function, social cognition and self-awareness...

CONTEXT:   Concussions in student-athletes are a serious problem. Most states have enacted legislation mandating concussion education for student-athletes, under the assumption that education leads to better self-reporting of concussions and improved knowledge of symptoms. OBJECTIVES:   (1) To determine the effect of state-based concussion legislation on the proportion of student-athletes receiving concussion education and to assess the moderation of this effect by gender and sport and (2) to assess the effect of concussion education on student-athletes' knowledge of concussion symptoms and likelihood of seeking treatment after a concussion...

AIMS: To assess the importance of service demographic, mental disorders, and deployment factors on headache severity and prevalence, and to assess the impact of headache on functional impairment. BACKGROUND: There is no information on prevalence and risk factors of headache in the UK military. Recent US reports suggest that deployment, especially a combat role, is associated with headache. Such an association may have serious consequences on personnel during deployment...

The majority of patients seeking medical care after head trauma have sustained injuries of mild or moderate severity, i.e., GCS scores of 13 to 15 or 9 to 12, respectively. Mortality rates under these circumstances are generally low; however, serious complications must be detected and treated early. The initial evaluation involves determination of level of consciousness and examination for the presence of focal neurologic deficits. Skull radiography has a limited role in the management of mild and moderate head injuries, but consideration must be given to local factors such as the availability of cranial CT...
