“…37 Sleep disorders in children after traumatic brain injury have been associated with poor functional outcomes. 24,38 Recent research has found athletes with pre-injury sleep difficulties are more symptomatic at baseline 39,40 and during the post-concussive period. 38 Our data support the relationship of pre-injury sleep disorder and prolonged post-concussive symptoms in a sport and non-sport concussed population.…”

Objective To determine the association between a history of somatization and prolonged concussion symptoms, including sex differences in recovery. Study design A prospective cohort study of 10–18 year olds with an acute concussion was conducted from July 2014 to April 2015 at a tertiary care pediatric emergency department. 120 subjects completed the validated Children’s Somatization Inventory (CSI) for pre-injury somatization assessment and Post-Concussion Symptoms Score (PCSS) at diagnosis. PCSS was re-assessed by phone at 2- and 4-weeks. CSI was assessed in quartiles with a generalized estimating equation model to determine relationship of CSI to PCSS over time. Results The median age of our study participants was 13.8 years (interquartile range: 11.5, 15.8), 60% male, with analyses carried out separately for each sex. Our model showed a positive interaction between total CSI score, PCSS and time from concussion for females p < 0.01, and a statistical trend for males, p = 0.058. Females in the highest quartile of somatization had higher PCSS than the other three CSI quartiles at each time point (B −26.7 to −41.1, p-values < 0.015). Conclusions Patients with higher pre-injury somatization had higher concussion symptom scores over time. Females in the highest somatization quartile had prolonged concussion recovery with persistently high symptom scores at 4 weeks. Somatization may contribute to sex differences in recovery, and assessment at the time of concussion may help guide management and target therapy.

“…While factors such as age, severity of trauma, number of prior traumatic brain injuries and timing of prior TBI have been shown to impact the outcome of neurocognitive testing, few studies have evaluated the impact of sleep on recovery (Albrecht et al 2016;Gaudet and Weyandt 2017;Martindale et al 2017;Lau et al 2011;Sufrinko et al 2015;Singh et al 2016). Of these, one study (n = 348) demonstrated that patients with insomnia and reduced sleep times prior to TBI have a prolonged recovery post-injury as measured by the Immediate Post-concussion Assessment and Cognitive Test and Post-concussion Symptom Scale when compared to controls (Sufrinko et al 2015).…”

Another study demonstrated that poor sleep quality independently predicted cognitive dysfunction in post-TBI combat veterans when controlling for other variables such as PTSD, while others have corroborated that poor sleep prolonged cognitive recovery from TBI in non-combat patients (Martindale et al 2017;Singh et al 2016).…”

Background: Sleep disorders are common following traumatic brain injury (TBI). Methods: We review the literature regarding sleep disturbances in the acute and chronic phase following TBI in both the adult and pediatric population. Results: Acute and chronic disruption of sleep commonly follows TBI and contributes to morbidity commonly seen post-injury in both adults and children. This includes the direct effect of TBI leading to sleep disruption, as well as sleep disorders resulting from TBI itself. Pre-TBI neurocognitive testing is important to determine a baseline prior to injury, while disrupted sleep can also prolong recovery after TBI. Early recognition of sleep disturbances post-injury can lead to earlier treatment and limit the sequelae of TBI, as well as assist in recovery. Conclusion: We suggest that evaluation for sleep disturbances following TBI is a critical component of post-TBI assessment and management.

Context: There has been substantial growth over the past decade in sport-related concussion (SRC) research, yet no research to date has synthesized developments over this critical time period. Objective : to apply a network analysis approach to evaluate trends in the sport-related concussion (SRC) literature using a comprehensive search of original, peer-reviewed research articles involving human participants published between January 1, 2010 and December 31, 2019. Design : Narrative review. Main Outcome Measures : Bibliometric maps were derived from a comprehensive search of all published, peer-reviewed SRC articles on the Web of Science database. A clustering algorithm was used to evaluate associations among journals, organizations/institutions, authors, and keywords. The online search yielded 6,130 articles, 528 journals, 7,598 authors, 1,966 organizations, and 3,293 keywords. Results : The analysis supported five thematic clusters of journals: 1. Biomechanics/Sports medicine (n=15), 2. Pediatrics/Rehabilitation (n=15), 3. Neurotrauma/Neurology/Neurosurgery (n=11), 4. General Sports Medicine (n=11), 5. Neuropsychology (n=7). The analysis identified four organizational clusters with hub institutions: 1. University of North Carolina (n=19), 2. University of Toronto (n=19), 3. University of Michigan (n=11), 4. University of Pittsburgh (n=10). Network analysis revealed 8 clusters for SRC keywords, each with a central topic area: 1. Epidemiology (n=14), 2. Rehabilitation (n=12), 3. Biomechanics (n=11), 4. Imaging (n=10), 5. Assessment (n=9), 6. Mental health/Chronic Traumatic Encephalopathy (n=9), 7. Neurocognition (n=8), 8. Symptoms/impairments (n=5). Conclusions : The findings suggest that during the past decade SRC research has: 1) been published primarily in sports medicine, pediatric, and neuro-focused journals, 2) involved a select group of researchers from several key institutions, and 3) focused on new topic areas including treatment/rehabilitation and mental health.

The Effect of Preinjury Sleep Difficulties on Neurocognitive Impairment and Symptoms After Sport-Related Concussion

Abstract: Preinjury sleep difficulties may exacerbate neurocognitive impairment and symptoms after concussion. The findings may help clinicians identify athletes who are at risk for worse impairments after a concussion due to preinjury sleep difficulties.
