Teaching Points• Know your guidelines

▫NC: Gfeller Waller Concussion Act• Know what you don’t know (and where/who to

look for info)▫CDC, BIANC, Local Providers/Referral Sources

• Know your bonus prizes/red flags▫Cerebral bleeds, Orbital Floor

• Know your exam▫Vestibular-Ocular***

• Know your Options▫School is Key: Accommodate

Case• JA is a 16 year old women’s soccer player who

goes up for a header and instead knocks heads with an opposing player. She has initial dizziness and a headache as well as a left occipital contusion. These symptoms last for 1 hour and by the time she presents to the ER her symptoms have totally resolved. Her parents push for a CT for “clearance” which is normal. She presents to your clinic the next day because her athletic trainer her told her to. She remains subjectively symptom free.

Algorithm: In-Office•Concussion Algorithm: In-Office

▫A complex vascular and neurochemical process affecting the brain, caused by direct or indirect traumatic forces to the head

Case (cont)

Keys:• Not a

Structural, but a Functional Problem

• Loss of consciousness only occurs in only 10% of concussions.

What is a Concussion?

Signs/Symptoms of a Concussion• Physical

▫ Headache▫ Nausea▫ Dizziness▫ Impaired Balance▫ Phonophobia/

Photophobia▫ Tinnitus▫ Cervicalgia

• Cognitive▫ Confusion▫ Mental “fogginess”▫ Feeling slowed down▫ Concentration difficulties▫ Memory Impairment

• Emotional▫ Irritability▫ Sadness▫ Anger▫ Nervousness/Anxiety▫ Mood lability

• Sleep▫ Drowsiness▫ Sleeping more than usual▫ Restless sleep▫ Increased sleep

latency/Trouble falling asleep

Case (cont)

•Objective #1: Rule out ‘Badness’▫ie: When to send to ER or Need for

Imaging Signs of increasing pressure on brain

Loss of consciousness > 30 seconds Convulsions / seizures Deteriorating level of consciousness or behavior Headache that is rapidly worsening or

becoming severe Late onset of or persistent vomiting Late onset of or worsening amnesia / memory

loss Focal neurological signs (motor function, vision,

speech)

Case (cont)

Keys:• Do not interrupt

sleep to check for symptoms

Case (cont)• An appropriate evaluation in your office would include which

of the following? ▫ A review of her symptoms; a neurologic exam and send her

for a stat MRI▫ A review of her symptoms; a neurologic exam and a

concussion assessment tool ▫ A review of her symptoms; a few memory questions and a

balance test ▫ A review of her symptoms; order a stat MRI and blood

sample checking for elevated levels of S100 calcium binding protein B (S100B)

Algorithm: In-Office

VOMS•VOMS

▫Vestibular-Ocular injury: Rotational/Occipital blow Symptoms:

Migraine presentation On-field ‘dizziness’ Vision complaints (blurred, focus issues) Balance problems Motion sickness Anxiety in busy environments Problems with math/screen time/reading

Exam (cont)

•Neurocognitive: ImPACT▫ What is It?

One piece of the overall concussion evaluation and management process.

A sophisticated test of cognitive abilities. A tool to help health care professionals track recovery of cognitive

function A tool that helps health care professionals and educators make

decisions about academic needs following concussion▫ What isn’t It?

A cure-all for concussion. Concussions still happen.  A substitute for medical evaluation and treatment.

Not a tool to “Diagnose” The only tool out there

Case (cont)• Which of the following recommendations do you

have for her care?▫Have her go into “cocoon therapy” and go to

complete bed rest avoiding all electronic devices ▫She can warm up tonight at 50 % effort and if that

goes well, she can compete without any restrictions ▫Avoid any physical activities that raise her heart rate

and limit cognitive activities that “tire” her brain ▫Allow her to briskly walk the dog and do basic

tumbling moves and limit her Facebook time to less than 1 hour a day

Algorithm: In-Office

•Concussion Algorithm: In-Office

Rest• Gfeller Waller Accommodations• Physical Rest• Avoid activities that elevate heart rate• Applies to all activities: practice, competition, physical education,

dance, non-school based activities, household chores• Avoid further trauma / injury to the brain• Sleep is essential• Hydration/nutrition• 20-30 mins/light aerobic activity• Cognitive Rest• Limit concentration effort

▫ Homework, school work, job-related work▫ Texting, computer, video games or television use▫ May require changes to a normal academic day

• Bottom Line: Don’t do anything that makes symptoms worse!• Use symptom score

Case (cont)• Once she is asymptomatic, has a normal exam and

passes a concussion assessment tool, what level of exercise are you going to allow her first day back? ▫Allow her to briskly walk the dog and do basic tumbling

moves▫Light aerobic exercise (e.g. stationary cycle or walking

laps for 30 minutes) ▫Sport-specific exercises at moderate effort for less than

1 hour (e.g. moderate jog, moderate footwork drills, shooting drills)

▫Start out light for about ½ hour and if she tolerates that, allow her to progress to a full workout that first day

Algorithm: In-Office

•Concussion Algorithm: In-Office

Case (cont)

• What are you going to do for her if her symptoms plateau at 3-4 weeks?

▫ Arrange a referral to a concussion specialty clinic ▫ Arrange for a brain MRI and if it is normal she never really

had a concussion anyway ▫ Arrange for more extensive testing such as an ImPACT test

or CogState test ▫ Have her initiate a return to play protocol to see if it

aggravates her symptoms; if not, allow her to return to full activities once completing the protocol

• Be suspicious when:▫ A concussion seems to be stalling out after one week▫ Concussion symptoms continue after three weeks▫ Concussion symptoms come back shortly after increasing activities

• Is it still a concussion or is it something else (Bonus Prize)?▫ Inner ear problems▫ Cervical spine trigger points or facet problems▫ Migraine cluster▫ Post traumatic stress disorder▫ Something more serious?

Seizure disorder New presentation of brain mass/tumor Subdural hematoma

How do you evaluate someone for Post Concussive Syndrome?

Algorithm: In-Office

•Concussion Algorithm: In-Office

• Be suspicious of a concussion/PCS. “If in doubt hold them out”

• Be familiar with your algorithm; Know your exam (VOMS)• Signs/symptoms change. Evaluate the athlete looking at:

Cervicogenic, Psychogenic, Vestibular, Ocular, Migrainous, Executive dysfunction

• There are many tools to help you on the sidelines and in the office. The law recommends that you use one.

• Initial treatment is based on both physical and cognitive rest until the symptoms resolve.

• Returning to activities is gradual process once asymptomatic. RTP Protocols vary

• Work closely with all of the health care providers involved (athletic trainers, school nurses, consulting neurologist or neuropsychologists) to provide the best care for this complex problem.
