The neurocognitive sequelae of a sport-related concussion and its management are poorly defined. Detecting deficits are vital in making a decision about the treatment plan as it can persist one year or more following a brain injury. The reliability of traditional cognitive assessment tools is debatable, and thus attention has turned to assessments based on electroencephalogram (EEG) to evaluate subtle post-concussive alterations. In this study, we calculated neurocognitive deficits combining EEG analysis with three standard post-concussive assessment tools...

OBJECTIVES: There are notable gender differences in concussion as well as sleep. Sleep disturbance is a major symptom of post-concussive syndrome. The interplay between sleep disturbance, concussion, and gender has yet to be examined. The objective of this study was to determine whether sleep disturbance plays a role in the known gender differences associated with concussion. METHODS: Males and females (ages 10-35 years) completed a pre-concussion and post-concussion evaluation...

OBJECTIVE: To evaluate the performance of the EyeTribe compared to the EyeLink for eye movement recordings during a rapid number naming test in healthy control participants. BACKGROUND: With the increasing accessibility of portable, economical, video-based eye trackers such as the EyeTribe, there is growing interest in these devices for eye movement recordings, particularly in the domain of sports-related concussion. However, prior to implementation there is a primary need to establish the validity of these devices...

Objective: Repetitive subconcussive head impacts (RSHI) may lead to structural, functional, and metabolic alterations of the brain. While differences between males and females have already been suggested following a concussion, whether there are sex differences following exposure to RSHI remains unknown. The aim of this study was to identify and to characterize sex differences following exposure to RSHI. Methods: Twenty-five collegiate ice hockey players (14 males and 11 females, 20...

PURPOSE: Describe the psychological impact of cognitive rest in adolescents recovering from concussion from sport-related concussion. METHODS: Eight male football players with a previous sport concussion and full recovery completed semi-structured interviews during focus group sessions. Using content analysis, the researchers independently analyzed notes and transcriptions to identify themes associated with the psychological impact of cognitive rest. RESULTS: Common themes included: 1) sport as social support, and 2) boredom-complicated recovery following cognitive rest...

OBJECTIVE: To determine which data collected on an initial patient clinic visit for a sports-related concussion (SRC) might influence physicians to clear an adolescent to return to drive (RTD) after injury. STUDY DESIGN: Retrospective cohort study of 189 adolescents with a SRC referred to a hospital-based concussion clinic between June 1, 2015, and May 31, 2016. Subjects were ≥16 years with a valid driver's license (median age = 16, IQR [16, 17]). Concussion evaluations included Post-Concussion Symptom Scale, modified Balance Error Scoring System, and postinjury computerized neurocognitive testing (CNT)...

BACKGROUND: Dizziness is commonly reported after concussion. With the forces experienced at the time of the injury, several anatomical locations may have been altered, causing dizziness. OBJECTIVE: Describe an objective examination and the types of impairment/dysfunction implicated by the results of clinical examination tests in subjects with dizziness after a concussion. DESIGN: Cross-Sectional. METHODS: Athletes between ages 10-23 were enrolled with a diagnosis of concussion...

Concussion is defined as a complex pathophysiological process affecting the brain that is induced by the application or transmission of traumatic biomechanical forces to the head. The result of the impact is the onset of transient symptoms that may be experienced for approximately 2weeks in most individuals. However, in some individuals, symptoms may not resolve and persist for a protracted period and a chronic injury ensues. Concussion symptoms are generally characterized by their emergence through changes in affect, cognition, or multi-sensory processes including the visual and vestibular systems...

BACKGROUND: Gait deviations resulting from concussion are important to consider in the diagnosis, treatment progression, and return to activity after a concussion. OBJECTIVE: To identify quantifiable gait deviations associated with concussion across populations and time since injury. METHODS AND MATERIALS: Six electronic databases were systematically searched from January 1974 to September 2016. Studies selected included original data, had an analytic design, and reported a quantifiable gait parameter in individuals who had sustained a concussion as defined by the American Congress of Rehabilitation Medicine or related definitions...

Vestibular and oculomotor testing is emerging as a valuable assessment in sport-related concussion (SRC). However, their usefulness for tracking recovery and guiding return-to-play decisions remains unclear. Therefore the purpose of this study was to evaluate their clinical usefulness for tracking SRC recovery. Vestibular and oculomotor assessments were used to measure symptom provocation in an acute group (n=21) concussed≤10 days, prolonged symptoms group (n=10) concussed ≥16 days (median=84 days), healthy group (n=58) no concussions in >6 months...

OBJECTIVE: Tinnitus is a common disorder that may cause psychological distress and anxiety. The aim of this study was to investigate the association between anxiety disorders (ADs) and tinnitus in a large population. METHOD: We conducted a cross-sectional study using the National Health Insurance Research Database in Taiwan. Study subjects included 14,772 patients with tinnitus and 709,963 people in the general population who sought treatment in 2005. Distributions in ADs, age, sex, and medical comorbidities were compared between groups using chi-squared tests...

OBJECTIVE: The purpose of this study was to compare the working memory (WM) performance pre- and post-concussion, and investigate the relationships between performance changes and characteristics such as self-reported symptom scores, number of days post-injury and age at injury in 10-14-year-old youth. METHODS: Twenty-one youth (17 males) aged 10-14 years recruited from the community completed verbal and non-verbal WM tasks pre- and post-concussion. Performance was measured using accuracy and performance errors (false alarms and misses)...

OBJECTIVE: The objective is to measure the prevalence of depression after traumatic brain injury (TBI) and the features associated with increased risk in a cohort that reflects clinical practice. METHODS: Prospective TBI admissions to a large Teaching Hospital Emergency Department were recruited over a 2-year period. Assessments for depression and other psychosocial and global outcomes were completed at 3 months post-injury. Comparisons were made with demographic and injury features of interest to establish any associations of depression risk...

BACKGROUND: As a collision sport, football carries a significant risk of injury, as indicated by the large number of pediatric football-related injuries seen in emergency departments. There is little information in the medical literature focusing on the age-related injury patterns of this sport. Our purpose was to evaluate the types of football-related injuries that occur in children and adolescents and assess which patient characteristics, if any, affect injury pattern. METHODS: Retrospective chart review was performed of football-related injuries treated at a level 1 pediatric referral hospital emergency department and surrounding urgent care clinics between January 2010 and January 2014...

OBJECTIVE: To examine and describe normative values for an objective, mobile measure of postural stability commonly used in concussion assessments, SWAY Balance (SWAY Medical, Tulsa, Oklahoma). DESIGN: Retrospective analysis of baseline balance assessments in a healthy pediatric population.

OBJECTIVE: To determine whether decreased sleep duration postconcussion influences days to asymptomatic and assessment of performance throughout recovery. DESIGN: Prospective. SETTING: Institutional Clinical Research Laboratory. PATIENTS: Four hundred twenty-three collegiate athletes were diagnosed with concussion. INTERVENTIONS: Multidimensional concussion assessment battery was conducted at baseline, within 24 to 48 hours, daily [2-4 days postinjury (PI); symptoms only], once asymptomatic, and after return-to-play...
