Frequently Asked Questions

How do you define concussion?

A concussion is a microscopic biomechanical traumatic brain injury (TBI) caused by a bump, blow or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth, resulting in a cascade of chemical changes in the brain. This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in the brain and sometimes stretching and damaging brain cells.

What are the signs of concussion?

  • Can’t recall events prior to or after a hit or fall
  • Appears dazed or stunned
  • Forgets an instruction, is confused about an assignment or position, or is unsure of the game, score or opponent
  • Moves clumsily, or stumbles
  • Answers questions slowly
  • Loses consciousness (even briefly)
  • Shows mood, behavior or personality changes

What are typical symptoms of concussion?

Physical

  • Headache
  • Nausea or vomiting
  • Blurry or double vision
  • Dizziness or difficulty with balance
  • Sensitivity to light, significant sensory stimulation (for example, having difficulty in a crowded room)

Mental

  • Confusion
  • Difficulty concentrating
  • Problems remembering
  • Feeling foggy or slowed down

Emotional

  • A strong emotional reaction to having been injured
  • Feeling sad or down
  • Decreased interest in hobbies
  • Irritability or moodiness
  • Nervousness
  • A desire to be isolated from other people or a concern about participating in community activities

Sleep

  • Difficulty falling or staying asleep
  • Sleeping more or less than usual
  • Drowsiness

What do I do if I think I have experienced a concussion?

If you are playing a sport, let your coach and/or athletic trainer know immediately. Otherwise, seek the help of an individual who can help you seek medical attention as soon as possible. If you think an athlete has a concussion, remove the athlete from play immediately. The athlete should sit out of play the day of the injury and should not return to play until a licensed medical professional says they are safe to return.

Children or teens who return to play too soon—while the brain is still healing—are at greater risk for a repeat concussion, worsening of current concussion or sustaining another musculoskeletal injury.

When will my concussion symptoms start and how long will my concussion last?

Concussion symptoms vary widely, depending on many factors (e.g., pre-injury headache, age, severity of injury, etc.). Although signs and symptoms generally show up within 48 hours after the injury, the signs and symptoms of a concussion can take minutes, hours or even days to appear. It is important to continuously check for signs of a concussion right after the injury and a few days following the injury. You should seek medical attention if you have symptoms of concussion.
Recovery is influenced by several factors. About 80% of people who suffer a concussion recover fully within one month of the injury, with adolescents taking slightly longer than adults or younger children.

What tests can tell if I have had a concussion?

Unfortunately, there is no specific test to diagnose a concussion. A concussion cannot be seen on CT or MRI scans. Concussion remains a clinical diagnosis, meaning it can only be made by health care professionals. A physical exam and thorough neurologic history are the best ways to diagnose a concussion. There are many research programs looking for a “biomarker” to predict concussion diagnosis, but none are valid for clinical use.

What is the best treatment for concussion?

As soon as you suspect you may have sustained a concussion, seek immediate medical attention to determine your plan of care. UCLA BrainSPORT is one of only a handful of comprehensive programs in the country dedicated to the neurological concerns of athletes through the multidisciplinary BrainSPORT outpatient clinic.

To make an appointment with the BrainSPORT clinic, please contact us.

An appointment to see an expert in concussion management should be made so that an appropriate treatment plan can be put in place. Whether or not emergency care occurred, beginning outpatient care within 1–5 days of injury allows for an individualized treatment plan to be started.

If you or your child has a sports concussion, our specialists at the BrainSPORT clinic may recommend the following recovery process.

  • Rest. Rest helps an injured brain heal. Keep your child to a regular sleep schedule.
  • Avoid high-risk activities. Until your child’s doctor gives the okay, your child should stop participating in sports, as well as refrain from activities that could cause another bump to the head or body. These include biking, skateboarding, climbing playground equipment and participating in gym class at school.
  • Limit technology. Restrict the use of computers, video games, smartphones and television viewing. These activities can over-stimulate the brain and worsen concussion symptoms.
  • Manage schoolwork. Children with concussions may find it difficult to concentrate on school work. Your UCLA doctor will work with you and your child to customize a plan for resuming assignments.
  • Symptom-limited activity. In some cases, we may actually recommend cognitive activities that challenge the brain or non-contact exercise to help with recovery.

As symptoms begin to improve, gradually increasing physical activity should be encouraged. Until recently, the recommendation had been to rest until asymptomatic. New studies, including ones performed at BrainSPORT, suggest that limited exercise during this time allows for quicker recovery from concussion. The type of exercise that is tolerated during this time is dynamic and varies from individual to individual based on symptom burden. Determining the appropriate type and amount of exercise is part of individualized care that should be guided by a healthcare professional.

I am an athlete who has had a concussion. When can I return to my sport?

A previously concussed athlete should only return to sports with the approval of a licensed health professional. The Centers for Disease Control and Prevention (CDC) and American College of Sports Medicine (ACSM) recommend a five-step return to play progression that should be supervised by a healthcare professional. When in doubt, sit it out!

What equipment can I use to prevent a concussion?

Though wearing a helmet is crucial to help reduce the risk of a serious brain injury or skull fracture, helmets are not designed to prevent concussions. Researchers and helmet manufacturers continue to work to improve helmets and other protective gear in order to make gameplay as protective as possible, but unfortunately, there is no “concussion-proof” helmet.

What are the “red flags” or signs of a more severe traumatic brain injury (TBI)?

In more rare cases, a serious brain injury can occur, in which a collection of blood can form in or around the brain following a hard impact.

If you notice any of the following symptoms following a hard hit, call 911 and seek medical attention immediately.

  • Loss of consciousness for more than one minute
  • Increasing confusion or inability to stay awake
  • Repetitive vomiting
  • Seizure or convulsion
  • Severe or increasing headache
  • Severe neck pain
  • Weakness, (numbness) tingling or burning in arms or legs
  • Persistent double vision
  • Increasingly restless, agitated or combative

What is post-concussion syndrome, or is its persistent post-concussion symptoms?

Historically, 10–30% of individuals have a recovery that is considered “longer than normal.” In the past this prolonged recovery has been called post-concussive syndrome. However, because many of the symptoms experienced in the month (or more) after a concussion may be subtle non-injury related issues that have been exacerbated by the concussion (e.g., headaches due to stress, sleep difficulties, deconditioning, etc.), a more accurate label is persistent post-concussion symptoms (PPCS).
Many factors likely play a role in the development of prolonged recovery. One main factor that may contribute to the development of prolonged recovery is the lack of appropriate recognition and treatment. Identifying the factors causing symptoms and initiating appropriate treatment for them is key for prevention of prolonged recovery. The multidisciplinary BrainSPORT clinic can provide a clear understanding of the best treatment plan for your concussion and current symptoms.

What are the long-term effects of sustaining a concussion?

  • From the current research, there is no clear evidence that a single, uncomplicated concussion (e.g., without structural damage on CT like a skull fracture) will cause lasting or progressive neurological deficits.
  • As a field, we are still learning about the long-term effects of repetitive concussions or subconcussive head impacts. Repeated mild concussions may result in a more prolonged recovery, particularly if concussion occurs in close proximity (e.g., an individual is still recovering from the initial concussion when the next concussion occurs).
  • There is evidence that a single moderate or severe TBI is much more likely to result in lasting neurological changes.
