Concussion = mild Traumatic Brain Injury (mTBI)
Concussion is a brain injury and is defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces.
May be caused by blow to head, neck, face, or blow elsewhere on body with forces transmitted to head
Typically results in rapid onset of short-lived impairment of neurologic function that resolves spontaneously• Symptoms and signs may evolve over minutes to
hours
May result in neuropathological changes, but acute symptoms reflect physiological, not structural changes• Standard neuroimaging is normal
Graded set of clinical symptoms• May or may not involve loss of consciousness• Symptoms may be prolonged

A public health problem
• Millions of concussions are estimated to occur in the U.S. annually– Range 1.2 – 3.8 million– Athletic trainer, pediatrician, urgent care, school
nurse
• The number of children receiving care for concussion is increasing – Increased mTBI diagnosis in ED over 10 years
• > 200% in children in 14-19 y/o• Doubled in 8-13 y/o

Concussion identification: A public health approach to a public health problem
• Legislation mandating – Education of coaches, athletes, and parents– Removal from play if concussion is suspected– No same-day return to play– Written clearance for return to play
from a medical professional with expertise in brain injury
• “Zackery Lystedt Law” Washington State, 2009
• 40+ states now have similar legislation
• Maryland’s law was signed on May 19th, 2011

Modifications: Conceptual background
• Recommendations for rest are based on “metabolic mismatch” of mTBI.
• In the initial days after injury, cerebral energy demands are increased but glucose delivery decreased
• Restricting activity modulates metabolic demands

Do’s and Don’t for the first few days
• Do:– Rest as needed– Sleep as needed– Return to daily activities as tolerated– Return to school as tolerated– Obtain guidance from medical/school personnel
• Don’t:– Persist in activities if symptoms worsen– Participate in PE, physical activity in recess, or
contact sports/high risk activities until cleared by healthcare professional

AAP Clinical ReportReturning to Learning Following a Concussion
• …adding additional restrictions that may not be needed has the potential to create further emotional stress during the recovery.
• There is insufficient research…although recent research suggests benefit to the concept of cognitive rest…
• This calls for an individualized approach…

Physical Modifications:WHEN IN DOUBT, SIT IT OUT
• “Second Hit Syndrome/Second Impact Syndrome”– Specific to children and teenagers– Occurs when a second, even mild injury, occurs in the
setting of a healing brain– Explosive swelling– Results in death or severe disability
• Even in absence of catastrophic injury, symptoms typically worsen/are prolonged after a second hit at any stage of recovery
• An athlete should never return to play if symptomatic

Prolonged Symptoms: Injury related factors
• Post-traumatic amnesia (PTA), LOC, and increased symptoms predicted prolonged recovery (> 7 days) (McCrea 2013)
• MVA, LOC, Neuroimaging abnormalities and hospitalization were associated with higher levels of prolonged post-concussive symptoms (Taylor et al 2010)

Prolonged Symptoms: Pre and Post-injury child and family factors
• Injury severity factors important early predictors• Child/Family factors important later predictors
– McNally et al. Neuropsychology, 2013
• Premorbid parent anxiety, child’s pre-injury concussive symptoms, child’s health-related quality of life– Olsson et al. Brain Injury, 2013
• Repeat concussions increase risk of more severe concussion and slower or incomplete recovery

A portable means of evaluating brain connectivity?
• Vibrations are applied to the fingertips.
• The ability of the child to sense the vibrations provides information about how brain cells communicate with each other.
• Portable technology lends itself to use in schools and at athletic events.

• Understand early (<1 week post-injury) and late changes related to concussion– Diagnosis of injury and recovery
• Understand whether changes in imaging or cellular connectivity persist after a child clinically appears to be back to baseline– Risk factors for future injuries?

Effects of Repetitive Concussion in Children
• Higher level of reported symptoms at baseline (Schatz et al 2011)
• More severe “on field” presentation of concussion if history of 3 or more prior concussions (Collins et al 2002)

Chronic Traumatic Encephalopathy (CTE)
• Late neurodegenerative process distinct from persistent post-concussive symptoms
• Recognized in boxers in 1928 (“dementia pugilistica”)
• Symptoms: – Early: impulsivity, irritability, mood disorder, short-term
memory loss– Late: dementia, gait and speech abnormalities,
parkinsonism
• Recent case report of CTE and motor neuron disease (ALS-like)

Chronic Traumatic Encephalopathy (CTE)
• Post-mortem diagnosis (Neuropathology) – Hyperphosphorylated tau protein deposits distinct from
Alzheimer’s disease – Diagnosis also in asymptomatic athletes (early
pathologic stages) and football players without clinical concussions
• Other contributing factors not yet clear– Genetics– Age at initial exposure to repetitive trauma– Other environmental factors
• Cohort studies are needed to better understand epidemiology, etiology, and risk factors

KKI Concussion ProgramLonger Term Research Goals
• Epidemiological study of large groups of children and teens with concussion– Long term follow-up – Understand rate of lasting and later effects of injury– Understand risk factors for lasting and later effects
