About this assessment
Answer a few questions about your child’s symptoms
Tell us what happened and what changes you’ve noticed so you can get personalized guidance on possible concussion symptoms in children, including signs that may show up after a sports injury.
01
How to tell if your child may have a concussion
A concussion can happen after a bump, blow, or jolt to the head or body, especially during sports. Some children have symptoms right away, while others seem fine at first and develop problems hours later. Parents often notice headache, dizziness, nausea, confusion, balance trouble, unusual sleepiness, or behavior that seems off. Because child concussion symptoms can be subtle, it helps to look at the full picture: how the injury happened, what symptoms started, and whether your child is acting differently than usual.

Common concussion warning signs in kids
Physical symptoms after a head injury
Headache, dizziness, balance problems, nausea, vomiting, blurry vision, and sensitivity to light or noise can all happen with a concussion. Symptoms may be mild at first and become more noticeable later.
Sleep and energy changes
A child with a concussion may seem very tired, nap more than usual, have trouble waking fully, or say they just don’t feel right. Sudden sleepiness after a head injury deserves close attention.
03
When symptoms show up later
Delayed concussion symptoms are possible
Not every concussion is obvious right away. Some children develop headache, trouble concentrating, mood changes, or dizziness hours after the injury, especially after the excitement of the moment has passed.
Sports injuries can be easy to underestimate
After a fall, collision, or hit during practice or a game, kids may want to keep playing even when something feels off. Concussion symptoms after sports injury can be missed if the child seems okay at first.
Watch for worsening patterns
If symptoms are increasing instead of improving, or new symptoms appear later, that can be an important clue. Tracking what changed and when can help you decide what to do next.
04
What parents can do next
Notice what is different
Think about your child’s usual behavior, energy, balance, and mood. Small changes matter when you’re trying to understand head injury concussion symptoms in a child.
Use a symptom-based assessment
Answering a few focused questions can help organize what you’re seeing and provide personalized guidance based on your child’s age, symptoms, and how the injury happened.
Know when urgent care may be needed
If your child is very hard to wake, has repeated vomiting, worsening confusion, severe symptoms, or you feel something is seriously wrong, seek immediate medical care.

How can I tell if my child has a concussion after sports?
Look for symptoms that start after a hit, fall, collision, or sudden jolt during sports.
