The acute and long-term neurobiological sequelae of concussion (mild traumatic brain injury [mTBI]) and sub-concussive head trauma have become increasingly apparent in recent decades in part due to ne...
Mild traumatic brain injuries (mTBIs) are common among Veterans. Although the majority of neurobehavioral symptoms resolve following mTBI, studies with Veteran samples demonstrate a high frequency and...
Mixed method open clinical trial of 12 combat Veterans with a history of mTBI, chronic neurobehavioral complaints, and psychological distress. Measures included qualitative and quantitative indicators...
The protocol was successfully delivered via in-person and telehealth treatment modalities (4.3 sessions attended on average; 58% completed the full protocol). Patient interview data suggested that tre...
Further study with a more diverse, randomized sample is warranted. (PsycInfo Database Record (c) 2023 APA, all rights reserved)....
Approximately 15 % of individuals who sustained a mild Traumatic Brain Injury (TBI) develop persistent post-concussion symptoms (PPCS). We hypothesized that blood biomarkers drawn in the Emergency Dep...
To test the hypothesis that a history of traumatic brain injury (TBI) prior to the collegiate pre-season is associated with risk for re-injury. We also investigate sex differences, cognitive functioni...
A longitudinal cohort study consisting of collegiate athletes (...
There were 40 new concussions recorded between P1 and P2, 21 (53%) of which were among athletes who reported a lifetime history of mild TBI/concussion at P1. New P1-P2 concussions occurred in 24% of f...
Collegiate athletes with a lifetime history of TBI had a significantly higher risk of sustaining a subsequent concussion. Pre-season emotional and somatic symptomology may contribute to incident concu...
The Sports Concussion Assessment Tool-5 (SCAT5) has been recommended for concussion evaluation and utilizes both a subjective reported symptom grading scale and objective measures of concussion includ...
To determine the diagnostic accuracy of components of the SCAT5 and to provide a framework for clinical interpretation....
This prospective case-control study of National Collegiate Athletic Association Division I athletes from any sport was conducted from July 2020 to December 2022 at 4 universities. Athletes completed b...
The primary outcomes were area under the receiver operating characteristic curve (AUC), sensitivity, specificity, positive and negative predictive value, and test-retest reliability of the symptom sco...
Baseline and postinjury data were collected on 92 athletes with concussion and 92 matched control athletes (96 men [52%] and 88 women [48%]; 110 who played a sport other than football [59%]). Diagnost...
In this case-control study of the diagnostic accuracy of reported symptoms and the SAC, reported symptoms were the most accurate indicator of concussion while the 10-word SAC had limited sensitivity. ...
To understand the methodological approaches taken by various research groups and determine the kinematic variables that could consistently and reliably differentiate between concussed and non-concusse...
MEDLINE via PubMed, CINAHL Complete via EBSCO, EBSCOhost, SPORTDiscus, and Scopus were searched from inception until 31 December 2021, using key terms related to concussion, mild traumatic brain injur...
Twenty-three studies involving 1030 participants met the inclusion criteria. Ten outcome measures were reported across these articles. Some metrics such as gait velocity and stride length may be promi...
Given the current status of the literature and the methodologies reviewed, there would seem little consensus on which gait parameters are best to determine return to play readiness after concussion. T...
Results of this study may have an impact on what technology is chosen and may be utilised to assist with concussion diagnosis and return to play protocols....
There have been growing concerns around potential risks related to sports-related concussion and contact sport exposure to repetitive head impacts in young athletes. Here we investigate WM microstruct...
The study included 78 collegiate athletes (24 football players with sports-related concussion, 26 football players with repetitive head impacts, and 28 non-contact-sport control athletes), available t...
Significantly increased axial kurtosis in those with sports-related concussion compared with controls was observed diffusely across the whole-brain WM, and some focal areas demonstrated significantly ...
This study highlights the fact that there are differences in diffusion microstructure measures that are present not only between football players with sports-related injuries and controls, but that th...
While individual susceptibility to traumatic brain injury (TBI) has been speculated, past work does not provide an analysis considering how physical features of an individual's brain (e.g., brain size...
The aim of this study was to assess whether a history of prior concussions, and especially multiple prior concussions, is associated with clinical recovery following a subsequent sport-related concuss...
A naturalistic observational cohort study....
Eleven National Collegiate Athletics Association Division III colleges....
Collegiate athletes sustaining concussions from September 2014 through March 2020....
Participants were divided into 3 groups, athletes with: (1) no prior concussion history, (2) one prior concussion, and (3) 2 or more prior concussions....
Survival analyses were used to compare time to return to school and sports among athletes with a history of 0, 1, or ≥2 prior concussions....
Among the 1132 college athletes, there were no statistically significant group differences between those with 0, 1, or ≥2 prior concussions in total time to return to school or sports. There was a sta...
In summary, concussion history was not associated with time to return to sports following a subsequent sport-related concussion in these college athletes. On average, athletes with prior concussions d...
Identifying vulnerability factors for developing persisting concussion symptoms is imperative for determining which patients may require specialized treatment. Using cross-sectional questionnaire data...
