Discuss the physical, cognitive and
emotional symptoms of concussion
Discuss the educational implications of
concussion symptoms
Understand risk factors in prolonged
concussion recovery
Assist in the development of
appropriate physical, educational and
cognitive recommendations in the
return to learn and return to play
decision-making process

Just a Concussion
3.9 million activity/sports related
concussions per year (CDC)
Falls, accidents and assault
Media attention- professional sports,
legislation
Nearly all states now have legislation
regarding sports concussions
Washington was the first state to have such a
law
No athlete may return to sports if concussion
suspected
Further evaluation by licensed
professional
Complex pathophysiological process
effecting the brain induced by traumatic
biomechanical forces.
May be caused by direct blow to head, face
or neck, or elsewhere on body with “impulsive
forces” transmitted to head.
Typically involves rapid onset of short-lived
impairment of neurological function that
resolves spontaneously.
Clinical symptoms largely reflect
functional disturbance rather than
structural injury.
Results in graded set of clinical symptoms
that may or may not involve LOC.
No abnormality evident on standard
neuroimaging.

Metabolic Cascade
(hours to days)
Developing brain
(neuroplasticity vs. increased
vulnerability)
Overuse
(implications to exertion)
Neuroanatomical
involvement
Neuroplasticity: younger brains are still
developing and thus are more resilient to
trauma due to brain’s ability to form alternate
neural connections for function.
Vulnerability: higher mortality rate seen with TBI
in younger children likely due to higher rate of
cerebral edema.
Animal models support both factors.
Unilateral cortical lesions.
Recovery of function associated with increased dendritic
growth within uninjured cortex dependent upon use of the
intact forelimb.
Restraint of uninjured forelimb with overuse of the injured
limb results in failed dentritic enhancement, increased
lesion size in injured cortex, and longer behavioral deficits.
Some mitigation with delayed use: no lesion increase but
functional recovery still delayed.
Considerations Regarding
Resumption of ‘Activity’
(Silverberg, N. and Iverson, G., 2012. Jnl Head Trauma Rehab
Thomas, D., Apps, J., Hoffmann, R., McCrea, M., Hammeke, T. 2015. Pediatrics)
Complete rest beyond 3 days probably
not helpful in most cases (not all)
Gradual resumption of preinjury, non
impact activities should begin as soon
as tolerated
Supervised exercise of benefit to patients
with persistent symptoms both physically
and emotionally
Caution re early restrictions establishing a
“mindset” for recovery expectations
Physical symptoms and altered mental
status usually first noted
Physical symptoms often improve before
cognitive.
Cognitive symptoms may worsen during
first 48-72 hours due to cellular and
metabolic changes.
Majority of pediatric cases with mild
injury are back to baseline at ???

Don’t panic
10-20% of pediatric concussions can
take 3 weeks or more
HS athletes take twice as long as
college/professional athletes to recover
(10-14 days vs. 3-7 days)
Younger kids take longer
They will get better, even if it takes a
while
Psychosocial stress
Previous history
Bright kids
Concussions
Anxiety
Headaches
Depression
Family hx of HA
Chronic medical
illness
Difficulties at home
Learning disabilities
ADHD
Dyslexia
Sleep problems
Prior high standard of academic
performance
“Overnight” changes to functioning
More time needed for homework/studying
Frustration with current deficits
Increased cognitive exertion exacerbates
symptoms
Teachers/peers not aware b/c student at
grade level
Student feels unsupported/deficits minimized
At risk for depression/anxiety/pessimism re:
future
Headache- most common
Makes concentration difficult
Avoid triggers (e.g. lights, noises, subjects (math,
high level science, foreign language)
Is this present at baseline
Limit NSAIDs
Focus on sleep
Riboflavin, magnesium, fish oil
Occasionally consider amitriptyline or neuro
referral
Dizziness/lightheadedness
Vestibular system/sensory organization
problem
Usually worsened by quick movements, video or
hallways
Vestibular therapy
Lightheaded- sense that they may pass out
with position change
More problematic because of limited cerebral
perfusion
Light aerobic activity or exercise in lying position
Careful position changes
Nausea
Zofran
Neck strain- often present with head
injury
Sometime can drive symptoms, even cause
dizziness
Treat with heat, PT, massage, even muscle
relaxers at times
Sleep disturbance – makes most
symptoms worse
Can’t fall asleep, wake up at night,
excessive napping
Affects ability to attend and focus, new
learning is difficult
If you don’t sleep you can’t do anything
well, even without a head injury
Treat aggressively- sleep hygiene, melatonin,
sometimes other meds
Mental health
Head injuries have a way of unmasking underlying
problems
Depression, anxiety, conversion disorder
Concussed kids lose coping strategies (high
performance in sports or school, exercise for stress
relief, social interaction, video games)
Address and normalize what they are going through
Psychology referral when necessary
Difficulty with concentration and short
term memory
Often most persistent symptoms
School accommodations
Patience (often take months, reassuring
when there is a trend toward improvement)
Often pre-existing learning issues
Stimulants on occasion
Cognitive rehabilitation
Neuropsychology referral
Need for education re management
Presence of preinjury risk factors: learning,
attention, psychosocial
Cognitive challenges
School issues
Change in behavior, mood, personality
Undue parental, coach pressure re RTP
Need for cognitive clearance for RTP
Collaborative effort between student, parents,
educators, coaches, and health care
professionals
Careful plan to facilitate transition/reduce risk of
failure
Focus on individual student needs (current
functional deficits, pre-existing risk factors,
academic status)
Set clear goals with student
Close monitoring and feedback to
student/parents
Adjust plan with recovery
Modifying the school schedule (reduced
endurance, fatigue, processing)
› Reduced school day/late arrival
› More frequent breaks in school day
› Additional study period/study skills class
› Drop classes with significant new learning:
foreign language, higher-level math and
science classes (e.g., calculus, physics,
chemistry)
Safety precautions
(increased vulnerability,
Increased distractibility)
› No PE
› No activities in gym or on playground
› No woodshop, auto mechanics, any class
with risk of injury
› Early dismissal from class to avoid crowded
hallways
Environmental accommodations
(inattention, sensory sensitivity)
› Preferential seating
› Reduction of distractions
› Testing in a quiet environment
› Avoid noisy environments (e.g., cafeteria,
assemblies)
› Rest periods in nurse’s office if
headaches/fatigue
Adjusting requirements/grading
(reduced cognitive resource, fatigue,
slowed processing)
› Forgive missed work
› Grades based on completed/representative
work
› “Freeze” grades
› Assign incompletes
› Use pass/fail option
Modifying assignments (processing,
attention, memory, learning)
› Decrease work load (e.g., length of spelling/
vocabulary word list, even or odd math
problems)
› Use aides: calculators, computers, “cheat
sheets”
› Assign peer note-taker
Modifying tests (processing
speed, retrieval)
› Untimed testing option
› Open book, “cheat sheets,” note
cards
› Recognition tests (multiple-choice,
T/F)
› Assistance with first few
steps/problems
Support for new learning
› Review of previously learned academics
› New material/concepts presented in context of
›
›
›
›
familiar or already-acquired knowledge
New material/concepts broken down into small
chunks
Multimodal instruction
Repeated exposure to novel information
Frequent review of new material
Implement schedules, calendars, to do lists
Maintain pictures/lists of assignments
Break down large tasks
Frequent reinforcement
Provide concrete time limits and
communicate them directly (verbal, written,
timer, task-based)
Frequent feedback, and redirection if
needed

Approximately 24 hours (or longer) in between each step

If symptoms increase, seek medical attention

http://www.cdc.gov/concussion
Concussion is a multifaceted and complex
functional injury.
Neurocognitive symptoms may be present
which are not immediately evident during the
first few days of evaluation.
Recovery course from concussion is variable
with outcomes determined by previous risk
factors, injury severity, past concussions and
management.
Caution is warranted with all concussions and
return to activity remains a medical decision
which should be informed by ongoing
attention to physical, cognitive, and emotional
factors.
