Objective: Persisting concussion symptoms may adversely affect return to work and functioning in daily activities. This study compared adults who were initially evaluated < 30 days versus those evaluated ≥ 30 days following a concussion at a specialty concussion clinic to determine if delayed initial evaluation is associated with persisting symptoms during recovery. Method: Participants (N = 205) 18 years of age and older who sustained a concussion and presented to a North Texas Concussion Registry (ConTex) clinic were evaluated at two time points: initial clinical visit and three-month follow-up. Participants provided medical history, injury related information, and completed the Sport Concussion Assessment Tool-5 Symptom Evaluation, Generalized Anxiety Disorder 7-item scale (GAD-7), and Patient Health Questionnaire (PHQ-8). Participants were divided into two groups: early and delayed evaluation (±30 days post injury). Results: Number and severity of concussion symptoms were similar between both groups at their initial clinical visit. However, linear regression models showed that a delayed clinical evaluation was associated with a greater number and severity of concussion symptoms along with greater aggravation of symptoms from physical and cognitive activity at three-month follow-up. Conclusions: Individuals who sought care at specialty concussion clinics regardless of previous care 30 or more days following their injury reported more serious persisting concussion symptoms at three month follow-up than those who sought care sooner. Education to improve adults' recognition of concussions when they occur and obtaining earlier clinical evaluation may represent important opportunities in promoting better recovery and reducing persisting concussion symptoms. This study 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 clinical evaluation of a concussion should be considered at initial evaluation by all providers and incorporated into prognosis and treatment planning. Concussion educational programs should be developed specifically for adults to promote recognition of concussions and importance of seeking prompt evaluation by specialized providers for this injury.

The objective was to examine the use of docosahexaenoic acid (DHA) for the treatment of sport-related concussion (SRC) in adolescent athletes. We hypothesize that participants who intake 2 g of DHA daily will not experience differences in recovery compared with participants who take a placebo. This double-blind, randomized controlled pilot trial was performed in a tertiary pediatric sports medicine clinic from 2013 to 2017 in adolescents (14-18 years) presenting with diagnosed SRC within 4 days of injury. Forty participants were randomized into DHA or PLACEBO group and were instructed to take 2 capsules twice daily for 12 weeks. Participants in the DHA group were symptom-free earlier than the PLACEBO group (11.0 vs 16.0 days, P =.08) and were cleared to begin the Return to Sport progression (14.0 vs 19.5 days, P =.12) sooner. The use of 2 g/day of DHA was well-tolerated and did not significantly affect recovery times in adolescent athletes following SRC.

Accurate assessment of balance recovery throughout treatment of a sport-related concussion is imperative. This study examined differences in balance from diagnosis to return-to-play initiation in adolescent patients post-concussion. Second, this study investigated the extent to which the Balance Error Scoring System (BESS) correlated with center-of-pressure (COP) measures. Forty participants performed the BESS while standing on a force platform such that COP data were obtained simultaneously. Spatial and velocity COP-based measures were computed for the double-stance conditions. BESS scores and COP-based measures indicated improved balance performance between visits. Specifically, 62.5/65.0% of participants exhibited improved firm/foam BESS final scores, respectively, and 56.4–71.8% exhibited improved COP-based measures. However, once normative ranges were referenced to identify maintained performance, the percentage of participants who substantially improved differed from initial findings (BESS: 2.5/7.5%, COP: 48.7–69.2%). Additionally, positive correlations between balance measures were primarily found at diagnosis (r=0.33–0.53), while only three correlations were maintained at return-to-play initiation (r=0.34–0.39). BESS scores successfully identified poor balance performance at diagnosis when symptoms were most pronounced, but failed to accurately depict performance once balance impairment, indicated by COP-based measures, became less apparent. Further work is needed to implement more advanced balance assessments into clinical environments. [ABSTRACT FROM AUTHOR]

Recovery and return to play are important milestones for athletes who sustain sport-related concussions (SRC). Several factors have been shown to influence resolution of post-concussion related symptoms (PCS), but resilience, a trait that reflects the ability to overcome adversity, is another factor that may influence recovery. The aim of this study was to determine the relationship of resilience with resolution of symptoms during recovery in adolescents and young adults following SRC. This prospective study is part of the North Texas Concussion Registry (ConTex). Subjects (N = 332) aged 13 to 25 years who sustained a SRC within 10 days of presenting to clinic were evaluated at two time points: initial clinical visit and three-month follow-up. Resilience was measured by the self-report Brief Resilience Survey (BRS) and PCS by the Sport Concussion Assessment Tool-5 Symptom Evaluation Post-Concussion Symptom Scale (PCSS). Recovery was determined by self-reported return to sports/physical activity and percent back to normal. Repeated measures ANCOVA and linear regression models showed that lower resilience ratings at initial visit were associated with a greater number and severity of PCSS symptoms along with higher levels of anxiety and depression symptoms during recovery from SRC. At three months, subjects with lower initial resilience ratings were less likely to report feeling back to normal and had greater aggravation of symptoms from physical and cognitive activity even when they had returned to sports/physical activity. Lower resilience was associated with greater symptoms and delayed recovery from SRC. Results suggest that resilience may be another important factor to address in recovery from SRC. Future research is needed to examine the extent to which resilience measured after SRC reflects pre-injury characteristics and to better inform the development of interventions to promote resilience during recovery.
