Early Postinjury Screen Time and Concussion Recovery

Objectives: To determine the association between early screen time (7-10 days postinjury) and postconcussion symptom severity in children and adolescents with concussion, as compared to those with orthopedic injury (OI). Methods: This was a planned secondary analysis of a prospective longitudinal cohort study. Participants were 633 children and adolescents with acute concussion and 334 with OI aged…

Characterizing Symptoms Before and Following Concussion in Professional Hockey

Do the types of symptoms matter in the acute evaluation period? Based on this study in professional hockey players by SNS members Jared Bruce & Ruben Echemendia and colleagues they do! Post injury cognitive, somatic/physical, and headache symptoms best differentiated concussed players and active controls. Pre-injury affective/emotional symptoms were also associated with increased likelihood of concussion among…

Test-Retest, Interrater Reliability, and Minimal Detectable Change of the Dynamic Exertion Test for Concussion

The Dynamic Exertion Test (EXiT) was developed to inform return-to-play (RTP) decision-making following clinical recovery from sport-related concussion (SRC). The current study established test-retest reliability in addition to minimal detectable change scores of an objective dynamic exercise assessment among healthy adolescent and adult athletes. The EXiT may be an objective approach to inform RTP decision-making…

Assessing the Assessments: Baseline Cognitive Evaluations

Two methods of baseline cognitive testing were evaluated in high school athletes. The authorsadministered the Immediate Post-Concussion Assessment and Testing (ImPACT), a commonly usedcomputerized concussion test, as well as more traditional paper and pencil neuropsychological measuresto a group of high school athletes. The study found that the ImPACT and paper and pencil tests measuredifferent aspects…

Early vs. Delayed Evaluation & Persisting Concussion Symptoms During Recovery In Adults

In this new article SNS members Stephen Bunt, Nyaz Didehbani, Ph.D. and C. Munro Cullum, Ph.D. found that a delayed presentation to a specialty concussion clinic (30 or more days post-injury) regardless of previous evaluation was associated with poorer recovery outcomes in adults compared to those with an earlier presentation. Time from injury to a formal…

Transition-Related Psychosocial Factors and Mental Health Outcomes in Former NFL Players

A recent study of former NFL players revealed that leaving their sport involuntarily and without a transition plan was associated with greater severity of current depressive and anxiety symptoms. Further researcher is needed to understand how transition-related factors influence functioning in athletes discontinuing participation from sport at lower levels of play (high school, college, etc.).…

Mild cognitive impairment and dementia reported by former professional football players over 50 years of age: an NFL-LONG study

Summary: The authors analyzed self-report questionnaire data from over 900 former NFL players (ages 50+). Their results revealed higher prevalence of self-reported MCI and dementia compared to the general population, with self-reported impairment associated with various health-related (reported concussions, depression, anxiety, recent pain, sleep apnea) and demographics-related (age, race) factors. https://pubmed.ncbi.nlm.nih.gov/34593716/ Walton, S. R., Brett,…

Longitudinal trajectory of depression symptom severity and the influence of concussion history and physical function over a 19-year period among former NFL players

Summary: The authors studied 333 former NFL players over a 19-year period to determine factors associated with severity and trajectory of depressive symptoms. Their data revealed an association between concussion history and severity of depression, as well as showed that declining physical functioning was associated with increases in depressive symptoms longitudinally. https://jnnp.bmj.com/content/early/2021/10/17/jnnp-2021-326602 Brett B.

Selected issues in sport-related concussion for the team physician: a consensus statement

This is the latest update to the Team Physician consensus statement on sport-related concussion developed by the Team Physician Consensus Conference (previous drafts published in 2006 and 2011).  The article delineates “essential” information that a team physician must understand and implement and “desirable” information that are considered best-practice in ideal settings.  The article then briefly…
