Purpose Academic difficulty is reported in children with prolonged post-concussive symptoms. Despite growing evidence that vestibular-ocular and vision-specific dysfunction are common in children following concussion, vision is rarely mentioned in return-to-learn protocols. The purpose of this project was to evaluate a cohort of children with prolonged post-concussive symptoms to determine if vision symptoms are associated with those reporting academic difficulty. Methods Data was obtained from the Children’s of Alabama Concussion Clinic REDCap dataset from the period January 2007 to October 2013. From this dataset of 1,033 concussion events, a cohort of 276 children aged 5–18 years with three or more concussion-related symptoms present for 10 days or more was identified. A cross-sectional cohort study was undertaken to evaluate the association of concussion symptoms, SCAT2 scores, demographic and concussion severity markers to reported educational difficulty among children with prolonged post-concussive symptoms. Univariate and multivariate logistic regression techniques were used to model the association of reported educational difficulty to self-reported vision abnormalities. Results Mean age was 13.8 years. Median time since the concussive event was 21 days, with 33% (95/276) reporting their concussion more than thirty days prior to data collection. Academic difficulty was reported by 29% (79/270) and vision abnormalities in 46% (128/274). After model reduction, vision symptoms (OR 2.17, 95% CI 1.02, 4.62), hearing disturbance (OR 2.39, 95% CI 1.06, 5.36) and concentration difficulty (OR 21.62, 95% CI 9.50, 44.47) remained associated with academic difficulty. For those with symptoms 30 days or more after concussion, only vision (OR 3.15, 95% CI 1.06, 9.38) and concentration difficulty (OR 15.33, 95% CI 4.99, 47.05) remained statistically significant. Conclusions Vision problems were commonly reported in children with concussions and were independently associated with those reporting academic difficulty. Comprehensive vision assessment should be considered in children reporting academic difficulty and in the development of return-to-learn protocols.

Recognition and diagnosis of sports-related concussion (SRC) among adolescents has significantly increased. In, fact, among high school adolescents, SRC incidence has more than doubled from 2007 to 2014, with recent estimates at approximately 2 per 100 athletes. SRC-related research has also increased; recognition of symptoms that may prolong recovery have been examined, potential biomarkers have been scrutinized, return-to-learn and return-to-play protocols have been developed and honed. However, to date, clinicians and researchers have struggled to find effective interventions to mitigate the significant symptoms after SRC and shorten recovery times. Despite the understood role of the brain as the primary regulator of metabolism, and the well-established metabolic impairments evoked after a concussion, nutrition is often ignored as a core complement to the recovery and rehabilitation process. In this article, we will identify deficiencies and/or inadequacies in nutrients post-concussion and provide support for potential exacerbation of injury and delayed recovery due to inadequate intake of nutrients prior to sustaining an SRC. Additionally, we will discuss the effect of derangement of the metabolic cascade post-concussion, and identify key nutrients, that if supplemented immediately post-injury, could increase neuroprotection, and improve recovery outcomes. Animal and cell culture studies have provided substantial evidence for not only the interrelationship of nutrient adequacy and the adaptation in the metabolic cascade post-concussion on neuroprotection, but also key nutrients that if supplemented immediately post-injury could enhance standard of care with minimal risk.
