  1. Berlin Consensus Statement October 27-28, 2017Fifth International Consensus Conference on Concussion in Sport Kristian Goulet MD Medical Director: Children's Hospital of Eastern Ontario, Eastern Ontario Concussion Clinic, & the Pediatric Sports Medicine Clinic of Ottawa May 27, 2017

  2. 11 ‘Rs’ of Sport-Related Concussion Management • Recognise • Remove • Re-evaluate • Rest • Rehabilitation • Refer • Recovery • Return to Sport • Reconsider • Residual Effects • Risk Reduction

  3. Recognize: Definition McCrory P, Meeuwisse W, Johnston K, Dvorak J, Aubry M, Molloy M, Cantu R. Consensus Stateent on Concussion in Sport: the 3rd International Conference on Concussion in Sport held in Zurich November 2008. Br J Sports Med. 2009 May;43 Suppl 1:i76-90. • “A complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces”

  4. Recognize: Symptoms Symptoms: somatic (eg, headache), cognitive (eg, feeling like in a fog) and/or emotional symptoms (eg, lability) Physical signs (eg, loss of consciousness, amnesia, neurolog­ical deficit) Balance impairment (eg, gait unsteadiness) Behavioural changes (eg, irritability) Cognitive impairment (eg, slowed reaction times) Sleep/wake disturbance (eg, somnolence, drowsiness)

  5. SRC may be caused either by a direct blow to the head, face, neck or elsewhere on the body • impulsive force transmitted to the head. • SRC typically results in the rapid onset of short-lived impairment of neurological function that resolves spontaneously. • signs and symptoms may evolve over a number of minutes to hours. • SRC largely reflect a functional disturbance rather than a structural injury • no abnormality is seen on standard structural neuroimaging studies. • SRC may or may not involve loss of consciousness. • Resolution of the clinical and cognitive features typically follows a sequential course. • However, in some cases symptoms may be prolonged. • The clinical signs and symptoms cannot be explained by other factors

  6. Remove: With Any Suspicion • The player should be evaluated by a physician or other li­censed healthcare provider on site • using standard emergen­cy management principles • particular attention to excluding a cervical spine injury and other “red flags” • Must be done in a timely man­ner. • If no healthcare provider is available, the player should be safely removed from play and urgent referral to a physician arranged. • Once the first aid issues are addressed, an assessment of the concussive injury should be made using the SCAT5 or other sideline assessment tools.(CRT5) • The player should not be left alone after the injury, • se­rial monitoring for deterioration is essential over the initial few hours after injury. • A player with diagnosed SRC should not return to play on the day of injury. • If a non physician does the initial assessment, follow up with a physician is recommended

  7. Re-evaluate: Post Injury Assessment (at the discretion of the physician) • Comprehensive history and detailed neurological examination including • A thorough assessment of mental status, cognitive functioning, sleep/ wake disturbance, ocular function, vestibular function, gait and balance. • Determination of the clinical status of the patient, includ­ing whether there has been improvement or deterioration since the time of injury. • This may involve seeking additional information from parents, coaches, teammates and eyewit­nesses to the injury. • Determination of the need for emergent neuroimaging to exclude a more severe brain injury (eg, structural abnormal­ity) • Physician (medically driven) makes diagnosis ASAP

  8. Rest • There is currently insufficient evidence that prescribing complete rest improves recovery. • After a brief period of rest during the acute phase (24–48 hours) patients can gradually increase activity • Needs to stay below their cognitive and physical symptom-ex­acerbation thresholds (ie, activity level should not bring on or worsen their symptoms). • Avoid vigorous exertion while they are recovering. • The exact amount and duration of rest is not yet well defined

  9. Rehabilitation • A variety of treatments may be required for ongoing symptoms • The data support interventions including therapies for mood and physiotherapy. • Closely monitored active rehabilitation programmes can be helpful • Exercise that doesn’t produce symptoms or puts them at any risk of getting injured • A collaborative approach to treatment is needed to: • Control the amount of thinking • Help them get back to school • Possibly use medications • Determining which therapies are needed. • Should be overseen by a trained physician

  10. Refer Persistent symptoms’ can be caused my many other things (not just the head injury) It takes a well experienced physician to determine which specialties/therapists need to be involved.

  11. Recover • Large majority of injured athletes recover, from a clinical perspective, within the first month of injury • Having a low level of symptoms in the first day after injury is a favourable prognostic indicator. • Development of subacute problems with migraine headaches or depression are likely risk factors for persistent symptoms • There are a number of factors that have been identified that are associated with a longer recovery • Physiological dysfunction may outlast current clinical measures of recovery, supporting a ‘buffer zone’ • Students should have regular medical follow-up after an SRC • May require TEMPORARY absence from school

  12. Return To Learn

  13. Return to sport; Graduated return-to-sport (RTS) strategy Return to Sport

  14. Reconsider • All athletes, regardless of level of participation, should be managed using the same management principles for athletes • Age is an important consideration • Clinicians need to be mindful of the potential for long-term problems such as cognitive impairment, depression • There is no accepted number of concussions that require retirement from sport. • Each case is individualized • The potential for developing chronic traumatic encephalopathy (CTE) must be a consideration • There is till is a lot to be learned about the relationship between head injury and CTE

  15. Risk Reduction • The evidence for mouthguard use in preventing SRC is mixed • meta-analysis suggests a non-significant trend towards a protective effect in collision sports, • More research is needed • Good evidence of the benefit of delaying body contact • Zero tolerance for head checking and strict enforcement of rules • Helmets work in skiing and snowboarding but not so far in ice hockey • Headgear in rugby and soccer need more research • Flexible boards and Glass has been show to decreased concussion risk • Knowledge Translation is important

  16. Neuropsychological Testing • Baseline or pre-season NP testing was not felt to be required • It may be helpful or add useful information to the overall interpretation of these tests. • It provides an additional educative opportunity for the healthcare provider to discuss the significance of this injury. • Post-injury NP testing is not required for all athletes. • Should optimally be performed by a trained and accredited neuropsychologist

  17. Other Discussion Points Biomarkers Brain Imaging Genetic Testing All require more research
