Concussion Key Facts

A concussion is an injury to the brain. Recognizing it is critical for a full recovery.

All injuries to the brain are potentially serious. The signs and symptoms of concussion may include headache, dizziness, memory loss, confusion, loss of balance, nausea and more.

An athlete with a possible concussion should immediately be removed from play.

If a sideline check suggests a concussion, the athlete should not return to play on the same day, and should see a licensed healthcare professional who is knowledgeable about concussions right away. Returning to play too soon can be dangerous or even deadly.

Getting better after a concussion usually just takes time.

Treatment normally involves stopping exercise and sports as well as mental activities that make symptoms worse, then gradually returning to activities.

Most athletes improve quickly after concussion.

Most athletes can safely return to school and sports within a week or two, although younger athletes may take a bit longer. Some athletes may take months or longer to fully recover. By law, a healthcare provider must approve an athlete’s return to play.

If symptoms persist, see an expert.

If the signs and symptoms continue to linger beyond 10-14 days, see a licensed healthcare provider who is an expert in diagnosing and treating athletes with concussions.


Concussion Basics

A concussion is a brain injury that changes the way the brain works. It is often caused by a direct hit to the head, face or neck. A sudden jolt to the body or a hard fall to the ground can also send enough force to the head to cause a concussion.

Nearly four million athletes and active people suffer a concussion every year. Most—90%—get better in a matter of days. But because all concussions are potentially serious, it is important to recognize and properly treat them early.

This information is for you if you want to learn more about concussions, including knowing the signs and symptoms, and what to do when you recognize one.

Why It Is Critical To Report Concussions

Many athletes don’t report their symptoms, and many coaches fail to recognize them.

It is important to report a concussion both to speed an athlete’s recovery and to prevent a potentially more devastating repeat concussion. The risk of a repeat concussion appears to be highest in the first 10 days after a concussion, and this heightened risk may continue for some time. During this period, the brain is more vulnerable to injury, even from minor hits or impacts.

The Treatment Is Usually Just Time

Recovering from a concussion is usually just a matter of time. For most, symptoms last about a week. Some people will improve almost immediately, while others take longer. Every athlete is different.

Experts recommend an initial period of brief rest followed by a gradual return to increasingly more demanding activities.

Return to Play: Weighing Pros And Cons

Deciding whether a child can safely return to sports—or whether sports risk too much harm—is the responsibility of a trained healthcare provider judging the individual circumstances of a particular young athlete. Informed athletes and parents are their critical partners.

Their choices usually include:

  • Returning the athlete to the same sport after fully recovered
  • Returning to a different sport or activity that has a lower risk of concussion
  • Stopping sports and activities that pose even a small risk of concussion

To participate in the decision-making conversation, parents will need to understand the risks and benefits of returning to play, and discuss with their child’s healthcare provider how they feel about them.

Concussion FAQs

What activities cause the most concussions in young people?

A 2011 report from the Centers for Disease Control and Prevention found that bicycling caused the most visits to hospital emergency departments for concussions in males and females age 19 and younger.

When broken down by sex, the number one cause of concussions (or “mild traumatic brain injuries”) was football among males and playground injuries among females.

The report tallied total number of concussions (not rates) from each type of activity. As a result, it was not able to show which activities caused the most concussions per 1,000 kids participating in the activity. By that standard, a lower-participation sport such as horseback riding would rank higher on the list.

Can blood tests or imaging scans diagnose a concussion or detect recovery?

Blood tests can’t yet reliably diagnose a sports-related concussion or track the brain’s progress toward recovery. Imaging tests are usually not recommended for the same reason. Researchers continue to explore new technologies, but there is no perfect test.

If symptoms worsen or don’t improve as expected, a healthcare provider who specializes in the diagnosis and treatment of concussions might recommend magnetic resonance imaging (MRI) or computed tomography (CT). These imaging tests can identify dangerous conditions such as a skull fracture or bleeding in the brain (called a hematoma). But these situations are unusual and undertaken with caution, in part because CT scans expose athletes to potentially harmful radiation.

What is the chance that a youth athlete will have a concussion?

Scientific evidence on concussions in athletes younger than high-school age is scarce. No organized method exists for collecting data across age groups and sports.

Despite these limitations, a 2015 study sheds some much-needed light on the risk of concussion in youth football. Researchers enrolled more than 3,000 football players ages five to 14 from 118 teams in six states. Athletic trainers attended each practice and game, and diagnosed the injuries.

They documented players’ concussions during two seasons:

  • Out of 100 youth athletes who played football for a full season, three had a concussion and 97 did not. (See chart.)

The authors reported similar rates of concussion at all three levels of football—youth, high school, and college.

smaller study of 351 female middle-school soccer players reported a considerably higher rate of concussions. Over the course of four years, parents used a sideline symptom checklist to diagnose injuries and report them through an online surveillance system. Among these elite players, 13 out of 100 had a concussion each season. The researchers believe the rates reported in other studies may be artificially low because many athletes do not report concussion symptoms to their coaches or athletic trainers.

What is the chance that a high school or college athlete will have a concussion?

Reported rates of concussion in high school and college vary widely. Estimating the true risk is difficult. In part, that’s because definitions of concussion vary from place to place and methods of collecting data are uneven. It’s also because many concussions are never reported.

One large, carefully performed study may provide a helpful estimate. In that study, researchers examined concussion data from 18,531 male and female athlete-seasons over the course of 10 years. The athletes all played collision or contact sports—football, soccer, lacrosse and ice hockey.

The results? Out of every 100 athletes who played a sport for a full season, three had a concussion and 97 did not. (See chart.)

Other studies have reported higher rates. For example, among high school athletes who play football or girls’ soccer for a full season, about 10 out of 100 report a concussion. Other studies have described much lower rates, especially in noncontact sports such as baseball or gymnastics.

 

 

Which high school and college sports have the highest and lowest risk of concussion?

The rate of concussion in specific sports varies widely from study to study, so it is difficult to rank sports from highest risk to lowest with true precision.

Risk in men’s sports. Most research shows that the risk of concussion among men is highest in rugby, football, ice hockey, lacrosse, soccer and wrestling.

Risk in women’s sports. Among women, soccer, lacrosse, ice hockey and basketball usually have the highest rates of concussion.

In sports where men and women play the same game by similar rules (for example, soccer and basketball), women generally have a higher rate of reported concussions than men. This may have to do with differences in physical characteristics or playing styles. It is also possible that women simply are more likely to report their injuries. To the surprise of some, the risk of concussion among women soccer players appears to be similar to that of male football players.

In virtually every sport, the rate of concussions is substantially higher during competitions and games than during practice. But injuries in practice are just as serious and deserve the same amount of medical attention.

The table below provides a rough estimate of concussion risk across a variety of high school and college sports.

Concussion risk in high school and college sports

(Sources: Zuckerman Am J Sports Med. 2015; Black Clin J Sport Med. 2016; Willigenburg Am J Sports Med. 2016; Graham IOM 2014; Marar Am J Sports Med 2012)

Why do some people take longer to recover than others?

Although research shows that concussion symptoms go away within a week for 90% of athletes, some take longer. The risk that recovery will take longer than 10-14 days may be greater in athletes who:

  • Had a greater number of symptoms at the time of their concussion (four or more)
  • Had more severe symptoms at the time of concussion, such as loss of consciousness (blacked out) or amnesia (memory loss)
  • Did not immediately report symptoms of a concussion and continued to play
  • Had a previous concussion
  • Had a recent concussion

Athletes in certain sports seem to be at greater risks of prolonged recovery. In one large, careful study:

  • Lacrosse players had more than twice the risk of a long recovery compared to soccer or football players
  • Ice hockey players had three times the risk of a long recovery

Athletes ages 13 through high school may also take longer to recover than college-age athletes, especially if they have had more than one previous concussion.

And recovery may be more difficult for people with certain medical conditions that they had before their injury. These include migraine headaches, depression, anxiety or panic attacks, learning disabilities and attention deficit/hyperactivity disorder, although some recent research has raised questions about these risk factors.

The current evidence suggests that male and female athletes are at similar risk for experiencing persistent symptoms and a prolonged recovery.

What should I do if the symptoms don’t go away?

A few athletes have symptoms that linger for weeks or months. In a study of high school and college athletes, about two out of every 100 athletes with concussions reported symptoms that lasted longer than one to three months.

Athletes with lasting symptoms report continued headaches, disturbed sleep, fatigue, slowed thinking and other problems. These can take a heavy emotional toll. Athletes may feel frustrated, irritable and restless.

If symptoms persist beyond 10 to 14 days, athletes should seek help from a comprehensive concussion program or a healthcare provider who specializes in the diagnosis and treatment of concussion. Healthcare providers who specialize in concussion management include:

  • primary care sports medicine physicians
  • physiatrists
  • pediatricians with sports medicine training
  • neuropsychologists
  • neurosurgeons
  • neurologists
Do helmets prevent concussions?

The short answer? No.

Helmets can prevent skull fractures, bleeding in the brain and other head and face injuries. But they can’t absorb the full force of a jolt that disrupts the brain and causes the many problems experienced by an athlete who has a concussion.

Do helmets lessen concussion severity? Research suggests that among athletes who have concussions, those who play sports with helmets and those who play without helmets have similar outcomes in the first few days after injury.

To the extent that helmets help, older helmets in good repair seem to offer the same level of protection as newer ones.

Movement, play and sports: What are the benefits?

The sports and activities children love often come with risks. But sports, movement and play also yield abundant benefits, and can enhance the physical, mental and social health of children long into the future.

The benefits of physical activity

  • Physical activity in childhood and adolescence can increase muscular strength, improve the ability to perform complex movements, build bone, improve mood, and increase heart and lung fitness.
  • Physical activity can help prevent inactivity-related diseases that occur in childhood, including Type 2 diabetes, asthma, high blood pressure, atherosclerosis (fatty buildup in blood vessels), asthma, sleep apnea and depression.
  • Physically active children are more likely to be physically active adults—and less likely to meet an early death or develop heart disease, breast and colon cancer, diabetes, obstructive lung disease, depression, anxiety or osteoarthritis.
  • Physical activity can help to prevent obesity and aid in its treatment.
  • Physical activity leads to better brain structure and function. It can improve thinking and mental performance, including focus, memory, attention and academic achievement.

SPORTS, MOVEMENT AND PLAY CAN ENHANCE THE PHYSICAL, MENTAL AND SOCIAL HEALTH OF CHILDREN LONG INTO THE FUTURE.

Sudden Cardiac Arrest: Six Key Facts

Sudden cardiac arrest is the number one cause of sudden death in exercising young athletes.

It usually strikes without warning in individuals with a structural or electrical abnormality of the heart, often inherited. Males, African-Americans and male basketball players are at increased risk.

No method of detecting heart problems in athletes is perfect.

A comprehensive medical history and physical exam is required for all young athletes before they participate in sports. Some medical experts are adding a screening electrocardiogram (EKG) to the standard pre-participation physical exam.

In some cases, warning signs or symptoms can help identify an athlete at risk of a sudden cardiac arrest

Signs of a potentially risky heart condition include fainting or passing out during exercise; excessive shortness of breath or chest pain with exercise; palpitations (heart racing) for no reason; and unexplained seizures.

Until proven otherwise, you should suspect sudden cardiac arrest in any collapsed and unresponsive athlete.

Unless effective emergency steps are taken immediately, death or serious disability will occur.

Every team should have—and practice—an emergency action plan for sudden cardiac arrest.

It is critical to review and practice your emergency action plan in the preseason with all personnel who may be involved in the emergency response.

Life-saving measures include calling 9-1-1, immediate chest compressions (cardiopulmonary resuscitation), and shocking the athlete with an AED as soon as possible.

Early initiation of all of these measures is important. Early defibrillation (shock) with an automated external defibrillator (AED) is the most important factor for survival. A few minutes’ delay can be the difference between life and death.


Sudden cardiac arrest: What it is and who is at risk

Every two to three days in the U.S., a young athlete dies as the result of sudden cardiac arrest. In fact, sudden cardiac arrest is the number one cause of sudden death in exercising young athletes.

In most cases, the arrest occurs with no warning. In the midst of play or practice, the athlete suddenly collapses. And if appropriate action is not taken within minutes, the athlete will die or be left with serious brain damage.

This information is for you if you want to learn about the causes of sudden cardiac arrest and the athletes who are at greatest risk. Being aware of the danger is the first step in preparing to save an athlete’s life.

Sudden cardiac arrest: Know warning signs and how to respond

In most cases, sudden cardiac arrest strikes young athletes without warning. However, in some cases, there are warning signs or symptoms that an athlete may have a heart condition that puts him at risk of a sudden cardiac arrest.

This information is for you if you want to learn how to recognize the signs and symptoms of sudden cardiac arrest and know the four essential steps in the “chain of survival.”

How to prepare for sudden cardiac arrest

It’s important to act quickly should one of your athletes suffer sudden cardiac arrest.
