7 Concussion Myths

As the country is focusing more on concussions, I've seen a lot more kids come in after head injuries, many of which are concussions. Even some kids who went to an ER after a head injury get incorrect information about return to play sometimes.

Common myths and misinformation about concussions:

1. A normal head CT means no concussion and a full return to play is okay.

Concussions are not diagnosed by CT. Brain bleeds and masses can be seen on CT, but the damage done to the brain during a concussion is not seen on a CT. Concussions are diagnosed based on symptoms, such as headache, confusion, lack of coordination, memory loss, nausea, vomiting, dizziness, ringing in the ears, sleepiness, and excessive fatigue. Not all symptoms need to be present to make the diagnosis. Some symptoms develop over time and are not present at the time of injury.

A CT scan is usually not needed with head injuries. They involve radiation so are not without risk themselves. Unless there are signs of a possible bleed in the brain, skull fracture, or the type of injury suggests the need for a CT, a CT scan is not needed in the evaluation for concussion.

2. A minor hit to the head never causes concussions.

The force of a hit does not determine the severity of the injury. Some people with more significant problems initially also seem to heal more quickly than others with more mild injury. It is very hard to predict how long it will be until all symptoms are resolved. The most important thing is that if you have symptoms of a concussion, your brain needs rest.

3. After two weeks you can return to play without further testing.

Sadly I've had more than one patient who was given this advice from a medical professional, whether on the sideline at a game or in an emergency room or urgent care. Although most concussions resolve within 2 weeks, not all do and returning to play before the brain is healed can lead to a more serious condition called "second impact syndrome." Second impact syndrome is a very rare condition in which a second concussion occurs before a first concussion has properly healed, causing rapid and severe brain swelling and often catastrophic results, including death.

After a concussion clearance to return to play should only happen when the child, teen, or adult is re-examined and found to be symptom free. Returning to play is done in a stepwise fashion, with each step lasting at least one day and only progressing to the next step if symptoms don't resume. This starts with light exercise when there are no symptoms at rest, then progresses to moderate activity followed by heavy activity without contact, then full practice with contact (if the sport is a contact sport) and finally full competitive play if each step can be done without return of symptoms. If symptoms return, you back up to lighter activity.

Returning to play too quickly can prolong healing time and even lead to long term consequences. Do not return to any activity that causes symptoms to worsen!

4. If a coach doesn't recognize the concussion, it's minor enough to return to play.

Coaches cannot see everything that happens on a field. If you had a head injury, tell your coach. Even if you are the star player. Really. You will do your team a favor if you take time to heal and can play again versus stay in the game and get more severely injured and are out for good. See these real stories of concussion survivors.

Someone who is trained in concussion evaluation should do a sideline evaluation. If there is any chance of concussion, you should not return to play at all that day or until you are cleared by a doctor who understands concussions.

5. IMPACT testing is necessary.

IMPACT testing is a computerized test that measures neurocognitive functioning. Ideally a baseline is done prior to the season (or at least every 2 years) and then testing is repeated if a concussion is suspected. The results of the current test are compared to the person's baseline and can be repeated at intervals until the person is back to baseline and able to be cleared to return to play. It is one tool to help manage concussions and determine when it is safe to return to play, but at this time concussions are diagnosed based on symptoms and physical exam.

6. Complete bed rest until all symptoms are gone is best.

Bed rest for the first day or two can help enforce brain rest and allow healing, but may not be required and prolonged bed rest is specifically not recommended. Prolonged bed rest can increase stress in children who miss substantial amounts of school. This stress is thought to possibly prolong healing. Depression is more common if bed rest is enforced beyond 48 hours. Socialization with friends and family can help provide emotional benefits that aid in healing. This does not mean that people should participate in all social settings. They will likely need relative quiet, so even going to a sporting event to watch can lead to return of symptoms.

7. Concussions only impact sports.

Concussions take kids out of play, but other activities should also be limited until they are tolerated. Lights, sounds and even smells can trigger symptoms after a concussion. If anything leads to worsening of symptoms, it should be avoided. Things that take focus or a lot of brain work may cause symptoms to worsen. These include reading, watching television, or playing video games. Initially a child might need total restriction from these activities, and then can slowly add them back in small increments as tolerated. Many kids need to have breaks during school, a decreased work load, and shouldn't take standardized tests until they can focus for a prolonged time. If computers are used for school, it might be necessary to use paper books and worksheets and to limit computer use until it can be tolerated.

It's [Sports, School, Camp, Yearly] Physical Time!

It's that time of year when school aged children and teens need physicals for school or camp entry or to participate in sports. Parents often want to work in a last minute "quick physical" for a form to be signed before a sport season starts or a child goes to a new school. Plan ahead so you can get an appointment at your preferred time!

Unfortunately some parents calling at the last minute are unable to get an appointment that fits their needs so they decide to go to a walk in clinic to just get the form signed. Keep reading to learn why this isn't a good substitute for a yearly physical in your child's medical home (AKA regular doctor's office).

Some parents don't think a yearly physical is important, and if not required to present a form to a school, sport, or camp, they simply don't do them. Their kids miss out on the benefits of a yearly physical.

Even when you think your child is healthy, there are several things that should be discussed, reviewed, and evaluated during the physical, so the visit isn't quick and it should be done in your child's medical home. If your child's regular physician is not available, there is still benefit to scheduling with another provider at your doctor's office as allowed by their policies. Past records are available to be able to compare current height to past growth. We can review vaccines and update as needed. We can update your child's record as needed since the last visit with new family medical history, changes in the home or school, and with your child's overall health.

Over the years I have "cleared" many student athletes by signing a pre-participation form required for high school sports or camps. On occasion I have not been able to sign the form, and this can lead to frustration for the athlete and his/her family.  If a physician or other licensed medical provider does not feel requriements have been met to "clear" an athlete for safe participation in sports, parents and their athlete often do not understand the "why" behind the need for further evaluation or treatment.

Common reasons to not clear an athlete for participation include recent concussion or a history of passing out that hasn't been fully evaluated.  I had one patient upset that I wouldn't sign the form because of a current broken bone... you can't play a sport in a cast! From the mother's perspective, she just wanted the form done today because the physical was today. From my perspective, the form can be signed when the child is able to play. I can't in good conscience say the student is able to play today if he is not. You don't want me as your child's pediatrician if I am able to attest to something I know is not true.

Please don't go to an urgent care or chiropractor to get the form signed when your regular doctor refuses due to a medical concern. I have seen parents do this -- omitting the fact that their child has passed out and needs further testing or had a concussion. That undermines the reason for the form in the first place! It is for your child's safety!

A glance at the Kansas Pre-Participation Physical Evaluation form's first page highlights many of the important topics to investigate. It would be impossible to completely cover every recommended topic at every physical, but standard recommendations include:

• Review of health history, including chronic conditions (such as asthma, diabetes, learning disabilities etc), hospitalizations, surgeries
• Review of family medical history
• Height, weight, Body Mass Index (BMI), vital signs (blood pressure, pulse, respiratory rate) - comparison to previous values is most helpful
• Puberty status
• Nutrition, exercise, and weight management issues - including performance-enhancing substances
• Sleep
• Risk factors (safety, smoke exposure, violence, alcohol use, screen time, internet safety, and more)
• Mental health (depression screening, drug/alcohol use, bullying)
• Physical exam (special attention to cardiac system, musculoskeletal, neurologic and other sport's preventing problems)
• Update vaccines as needed
• Laboratory evaluation as needed: cholesterol screening, anemia screening, and other risk-based testing

Not included in this list is following up chronic conditions, addressing the issues raised at the physical, refilling all medicines, etc. There are times that addressing one or two specific issues is appropriate, but often there isn't enough time to adequately address all concerns. A separate visit may be needed to be able to devote appropriate attention to each issue. Please don't save up a year's worth of concerns to discuss at one visit each year. 

A well visit is recommended every year for all children over the age of 3 years (more for younger children). If your child hasn't had a well visit in the past year, call today or request a physical through our portal! Don't wait until the last minute... summer physicals book quickly.

The yearly well visit can be used to address all sports and camp physical forms that need to be done. Please bring them to your visit with the appropriate sections pre-filled out to save time in the office.

Concussions in Athletes

Concussions in athletes has been the subject of many headlines over the past couple years.  For as much as we know about concussions, there is still much more we need to learn about head injuries and their healing. While most kids recover from concussions within days to weeks, there are some who suffer for months.  This can disrupt not only sport participation, but also reading, concentration, and the ability to learn.

What we know:

• We know that children's brains are still developing and are more at risk with concussions than mature brains. 
• We know that many athletes attempt to hide symptoms of a concussion so they can continue to play. (Bad idea!)
• After a concussion -- even serious ones that affect the daily activities of a teen -- kids are often eager to return to the game that puts them at risk for another injury.
• Symptoms of a concussion range from mild to severe.

• headache
• nausea or vomiting
• slurred speech 
• dizziness 
• ringing in the ears
• trouble concentrating
• sensitivity to light or noise
• sleep problems
• balance problems
• memory loss  

Treatments:

• There are no specific treatments for concussion.
• Rest is important. This includes not only avoiding activities that increase the risk of another injury, but also brain rest. Some kids need quiet time in bed without lights, sounds, television, computers, or books.
• Headaches can be treated with pain relievers and sometimes migraine medications.
• Memory and thinking problems are treated with rehabilitation and memory devices (like a calendar or planner).  Occasionally stimulants (the medicines used for ADHD) are used temporarily.
• Depression and anxiety should be managed by someone experienced in dealing with post-concussion syndrome.

Return to play is a gradual process, in which the athlete progresses in a step wise manner.  If any symptoms return during the stepwise process, the athlete must stop activities and return to a medical practitioner for evaluation.

Step 1: Light aerobic exercise 5-10 minutes without weight lifting, resistance training or other exercises

Step 2: Moderate aerobic exercise 15-20 minutes of running at moderate intensity without a helmet or other equipment.

Step 3: Non-contact training drills in full uniform. May begin weight lifting and resistance training.

Step 4: Full contact practice.

Step 5: Full game play.

Kansas has a new Concussion Law effective July 1, 2011, that requires the State Board of Education and the Kansas State High School Activities Association to provide information about the risks of head injury to coaches, athletes, and parents and guardians of the school athletes. This information should include the risks of playing or practicing with a concussion.  Under the new law an athlete may not participate in a school sport or practice unless the athlete and the parent/guardian have turned in a signed head injury release form each year.  Any school athlete who is suspected of having a concussion or head injury will immediately be removed from play or practice and will be allowed to return to play only after a health care provider gives medical clearance to return to play.

Athletic trainers are available at many local schools to help identify the athletes at risk of concussion. They will be testing kids with various methods, and at this time there is still a lot of variability in what each school program is doing.  It is best to have baseline testing done BEFORE any brain injuries (ie the start of the season) to compare to testing done after a suspected concussion.

If your child is suspected of having a concussion, bring any available test results (both from before and after injury if possible) to your appointment with a healthcare provider.

Prevention is still the best medicine!

• Wear proper gear at all times.  
• Be sure helmets are in good condition and fit properly. 
• Wear mouth guards at all times.  
• Follow the rules of the game. 
• Sit out if injured.  
• If you suspect someone might have a concussion, speak up!
