Concussion Definitions
• One definition of concussion is a condition in which there is a traumatically induced alteration in mental status, with or without an associated loss of consciousness (LOC).[ A broader definition is a traumatically induced physiologic disruption in brain function that is manifested by LOC, memory loss, alteration of mental state or personality, or focal neurologic deficits. (Medscape)
• A concussion is a traumatic brain injury that alters the way your brain functions (Mayo Clinic)
• A concussion is an injury to the brain that results in temporary loss of normal brain function (American Association of Neurological Surgeons)

SF's Borland quits over
safety issues
Borland, 24, said he notified the 49ers on Friday. He said he made his decision after
consulting with family members, concussion researchers, friends and current and former
teammates, as well as studying what is known about the relationship between football and
neurodegenerative disease.
"I just honestly want to do what's best for my health," Borland told "Outside the Lines." "From what I've researched and what I've
experienced, I don't think it's worth the risk."

Grades
• Concussions are graded as mild (grade 1), moderate (grade 2), or severe (grade 3), depending on such factors as loss of consciousness, amnesia, and loss of equilibrium.
• In a grade 1 concussion, symptoms last for less than 15 minutes. There is no loss of consciousness.
• With a grade 2 concussion, there is no loss of consciousness but symptoms last longer than 15 minutes.
• In a grade 3 concussion, the person loses consciousness, sometimes just for a few seconds.
• Still debate about grade classification as some state LOC can happen in a grade 2 concussion.

Clinical Tools
• Standardized Assessment of Concussion (SAC)
• Balance Error Scoring System (BESS)
• Symptom assessment
• SCAT 3 (includes SAC, BESS, others)
• ImPACT Testing
• Multiple others
• Good to have baseline established before the season.
• All can be adversely affected by either patient or examiner
• Not examined for validity under age of 12
• Some are costly to administer

When do we send to Emergency?
General guidelines
Prolonged LOC
Focal neurological findings
Worsening mental status
Seizure activity
Worsening headache
Repeated emesis
Concern is for structural injury requiring computed tomography (CT) scan

When Do We need to Refer?
Prolonged symptoms (should see improvement within 3 days)
Severe symptoms that are not improving
Your own individual comfort factor
Patient with multiple concussions
Decisions on retirement?
No “magic number”
Parental request

Treatment
• No medications have been proven to help with concussions
• Most medication management directed at specific symptoms
• Rest is the treatment (physical and “brain rest”)
• Avoid activity that can increase pulse or blood pressure
Reduced school day/off school
Reduced school load
Untimed tests
Tutoring
May need to limit video games, texting, reading, computer use, television
Consideration for restrictions on driving reduced reaction time is issue

Rest is the key

“Brain Rest” Complexity
Need to Involve the school early
Make adjustments
? days off
Follow up with schools on adjustments being made
High achieving students may not ‘give in’ to adjustments

Caution Advised

High School Sports Injury Stats
• In most sports the main mechanism of injury is contact with another player
• In softball and basketball the main mechanism is contact with equipment
• Younger the athlete, the longer to recover
• Although overall numbers are higher for football, there are a larger % of concussion vs overall injuries in Cheerleading, Boys and Girls Lacrosse, and Boys Hockey
• Girls typically take longer to recover and have more symptoms

Post-Concussive Syndrome
• People who suffer a head injury may suffer from side effects that persist for
weeks or months. Symptoms include memory and concentration problems,
mood swings, personality changes, headache, fatigue, dizziness, insomnia and
excessive drowsiness. Patients with post-concussive syndrome should avoid
activities that put them at risk for a repeated concussion. Athletes should not
return to play while experiencing these symptoms. Athletes who suffer
repeated concussions should consider ending participation in the sport.

Second-impact Syndrome
• Second-impact syndrome results from acute, often fatal brain swelling that occurs
when a second concussion is sustained before complete recovery from a previous
concussion. This is thought to cause vascular congestion and increased intracranial
pressure, which can occur very rapidly and may be difficult or impossible to control.
The risk of second-impact syndrome is higher in sports such as boxing, football, ice
or roller hockey, soccer, baseball, basketball and snow skiing.
• The CDC reports an average of 1.5 deaths per year from sports concussions. In
most cases, a concussion, usually undiagnosed, had occurred prior to the final one.

“Return to Play” Guidelines
• If concussion is suspected, do not allow return to play that day.
• No activity until asymptomatic at rest
• Then start to increase activity as tolerated each day:
• Light aerobic activity
• Sport-specific training
• Non-contact training drills
• Full contact training after medically cleared (Not a law in every state)
• Game play

What about our non-athlete
patients?
What can we do to help this guy?
![Page 24: Sport & Non-Sport Concussion: Recognition and Management › ... › 2016 › 10 › Concussions-presentation-F… · Grades •Concussions are graded as mild (grade 1), moderate](https://reader034.fdocuments.us/reader034/viewer/2022042323/5f0d09177e708231d4385b89/html5/thumbnails/24.jpg)
“Return to Work” Guidelines
• There are no accepted guidelines for accepted time off to return to work in a
non-professional sports setting. (Therefore our patient will have to use
vacation days and possibly FMLA)
• Most concussions (>80%) have patient back to baseline within 3 weeks.
