Sports-related concussion in children and adolescents

AGENDA: CONCUSSION MANAGEMENT UPDATE MEETING SEAFAIR MINOR HOCKEY - NOVEMBER 8TH, 2013 • Introduction: Medical Panel and Seafair Background on Baseline Testing and Concussion Management (Cody Kusch) • Background: Concussions and Recent Findings (Naznin VirjiBabul) • Medical Evaluation and Recovery Process (Dr. William Panenka) • Baseline Testing: SCAT 3 and Axon, update on testing to date, protocol for study, Return to play Protocol (Jonathan Sun) • Panel: Question and Answer Period (Cody, Bill, Naznin, Dr. Will Panenka, Jonathan Sun, Dr. Paul Korn)

Background: • Concussion/mTBI currently considered a ‘silent epidemic’

• Sports activities are a major cause of concussions • 300,000 sports related concussions occur each year in the United States

What happens to the brain during a concussion?

Shearing in the “wiring” of the brain

Issues for coaches/clinicians/parents:

• Standard neuroimaging tools not sensitive to detect subtle changes in brain structure and function • Diagnosis and evaluating functional recovery very difficult

Advanced MRI can “see” subtle changes in the wiring of the brain

No concussion

Concussed athlete

fMRI measures “thinking”

Brain activity is more “scattered”



Signs and Symptoms of Concussion • By an observer – not only LOC! – – – – –

Dazed or stunned, confused about assignment Forgets instruction, game score, opponent Off balance, answers slowly, loses consciousness Mood, behavior or personality changes. Amnesia for events around injury

• By the athlete – – – – – –

Headache, nausea or vomiting Balance problems or dizziness Double or blurry vision Sensitivity to light or noise Concentration or memory problems, confusion

Recovery From Concussion: How Long Does it Take?

Medical Evaluation • Individual clinical decision • A medical assessment including a comprehensive history and detailed neurological examination including a thorough assessment of mental status, cognitive functioning and gait and balance. • A 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 eyewitness to the injury. • A determination of the need for emergent neuroimaging in order to exclude a more severe brain injury involving a structural abnormality

Persistently symptomatic patient • Persistent symptoms (>10 days) in about 10-15% • Important to consider other issues • Should be managed in multidisciplinary manner by healthcare providers experienced in sport concussion

Child/teenage athletes • Consider age specific physical and cognitive rest issues – school attendance and activities need to be modified

• No return to sport or activity until returned to school successfully • Symptom resolution may take longer, modifiers apply even more • More conservative RTP approach recommended: – Consider extending symptom-free period before starting return to play protocol – Consider extending length of the graded exertion protocol

• Never return to play same day

Issues in the field • No “gold” standard for assessment • Return to play/learn protocols are based on “expert” opinion not hard evidence

Seafair Study • Use 2 different assessments to evaluate which one is most sensitive • Never been done before

Baseline and End of season Assessments: • SCAT3 Baseline: 341 players tested to date • AXON Baseline: Only 73 completed to date

Concussion Protocol Suspected Concussion Coach/Manager pulls player off the ice

SCAT3/AXON repeated

Referral to BCCH/Dr. Korn/Dr. Panenka as needed

Dr. ‘Naz’ to screen players for MRI study Must be within 1 week of concussion

Repeat scan if symptomatic at 6 weeks

Return to play protocol • 1. No Activity. Complete physical and cognitive rest • 2. Light aerobic exercise (Walking, swimming or stationary cycling keeping intensity
