Current clinical guidelines provide a unitary approach to manage sport-related concussion (SRC), while heterogeneity in the presentation of symptoms suggests that subtypes of SRC may exist. We systematically reviewed the available evidence on SRC subtypes and associated clinical outcomes. Ovid Medline, Embase, PsycINFO, and SPORTDiscus Electronic databases were searched for studies: (i) identifying SRC symptom clusters using classification methodology; or (ii) associating symptom clusters to… 

Effect of Sleep-Related Symptoms on Recovery From a Sport-Related Concussion

Athletes who reported mild, moderate, or severe sleep-related symptoms on the SCAT5 were at a proportionally increased risk of persisting symptoms at the initial office visit.

Sports psychiatry and medical views on mild traumatic brain injury in competitive sport: a current review and recommendations

As with mTBI and SRC, no standardized classification has been established for PCS, and multi-stage rehabilitation strategies can help injured athletes navigate a successful recovery and prevent premature return to play.

Paediatric post-concussive symptoms: symptom clusters and clinical phenotypes

Post-concussive symptoms in children occur in distinct clusters, facilitating the identification of distinct patient phenotypes based on symptom type and severity.

The Role of Reported Affective Symptoms and Anxiety in Recovery Trajectories After Sport-Related Concussion

This study examines the relationship between affective symptom reporting and RTP progression after SRC among a cohort of Division 1 student-athletes and finds that those endorsing affective symptoms, specifically nervous-anxious symptoms, spend more time in RTP progress and recovery.

Machine Learning for Subtyping Concussion Using a Clustering Approach

Understanding concussion in terms of Complexity with the utilization of artificial intelligence, could provide a more accurate concussion classification or subtype approach; one that better reflects the true heterogeneity and complex system disruptions associated with mild traumatic brain injury.

Improving subacute management of post concussion symptoms: a pilot study of the Melbourne Paediatric Concussion Scale parent report

The additional items and domain classifications in the Melbourne Paediatric Concussion Scale have the potential to improve subacute diagnostic precision, monitoring of clinical recovery and identification of appropriate interventions post pediatric concussion.

Multi-tract multi-symptom relationships in pediatric concussion

By defining cross-demographic multi-tract multi-symptom relationships to parse concussion heterogeneity, the present study can pave the way for the development of improved stratification strategies that may contribute to the success of future clinical trials and the improvement of concussion management.

Epidemiology of Rink Hockey-Related Injuries.

The injury incidence in rink ice hockey is moderate, occurring mainly due to a contact mechanism, and preventative measurements should be implemented in rink hockey with a special concern for injuries affecting the hip/groin and head.

Exploring Vestibular Ocular Motor Screening in Adults With Persistent Complaints After Mild Traumatic Brain Injury

Significant group differences support the relevance of the VOMS for mTBI in an age-diverse sample with persistent symptoms and strong association with DHI symptoms supports the ability of theVOMS to capture vestibular complaints in this population.

Clusters of conditions among US service members diagnosed with mild TBI from 2017 through 2019

Cl clustering techniques were used to determine if conditions co-occurred as clusters among those newly injured with mTBI and up to one year post-injury and identified six distinct subgroups that may help clinicians better understand the complex profile of SMs newly diagnosed withmTBI.



Concussion Guidelines Step 2: Evidence for Subtype Classification

Five concussion subtypes with varying prevalence within 3 d following injury are commonly seen clinically and identifiable upon systematic literature review.

Role of advanced neuroimaging, fluid biomarkers and genetic testing in the assessment of sport-related concussion: a systematic review

Advanced neuroimaging, fluid biomarkers and genetic testing are important research tools, but require further validation to determine their ultimate clinical utility in the evaluation of sport-related concussion (SRC).

Summary of evidence-based guideline update: Evaluation and management of concussion in sports

Data are insufficient to show that any intervention enhances recovery or diminishes long-term sequelae postconcussion, and practice recommendations are presented for preparation counseling, management of suspected concussion, and management of diagnosed concussion.

Concussion Symptom Profiles Among Child, Adolescent, and Young Adult Athletes.

Within 21 days after concussion, symptom-reporting behavior seems to be similar across the age spectrum, but the relationship between symptom profiles and time to symptom resolution varies by age.

The Postconcussion Symptom Scale: utility of a three-factor structure.

This investigation demonstrates a consistent symptom 3-factor structure of the Postconcussive Symptom Scale in pediatric patients with concussions, suggesting that prolonged concussion symptoms may affect emotional health.

A systematic review of diffusion tensor imaging findings in sports-related concussion.

It is suggested that DTI may possess adequate diagnostic sensitivity to detect SRC in affected athletes, and further longitudinal studies are required to demonstrate its discriminate validity and prognostic capacity within this field.

Concussion Subtype Identification With the Rivermead Post-concussion Symptoms Questionnaire

Elevated symptoms detected with the RPQ within as short as 2 weeks after a concussion may help delineate patients' clinical subtypes and guide their treatment.

A Revised Factor Structure for the Post-Concussion Symptom Scale

The current findings reveal different symptom factors at baseline and postinjury and several age and sex differences on the symptom factors.

Headache symptoms were significantly associated with overall cognitive impairment as well as memory and attention/processing speed impairment and sleep symptoms were related to memory impairments.

Multi-Disciplinary Management of Athletes with Post-Concussion Syndrome: An Evolving Pathophysiological Approach

This review presents an evolving evidence-based approach to evaluation and management of athletes with PCS that aims to identify the pathophysiological mechanisms mediating persistent concussion symptoms and guides the initiation of individually tailored rehabilitation programs that target these processes.
