4 Lesser Known Signs of Concussions in Kids
Most parents know to watch for loss of consciousness or vomiting after a head injury. But the reality is that only about 10% of concussions involve loss of consciousness. Many children show more subtle signs that are easy to attribute to other causes — or to miss entirely.
The Well-Known Signs (Brief Review)
Classic concussion warning signs include headache, confusion, dizziness, nausea, vomiting, and appearing dazed. If any of these are present after a head impact, remove your child from play immediately and seek evaluation.
4 Lesser-Known Signs Parents Should Know
1. Sleep Changes
Sleeping significantly more or less than usual, trouble falling asleep, or excessive grogginess are common post-concussion symptoms. Many parents attribute this to general fatigue or a growth phase. If it follows a head injury, it needs evaluation.
2. Emotional Changes
Irritability, sadness, emotional volatility, or feeling “not like themselves” — post-concussion mood changes are documented and real. The brain injury affects emotional regulation. If your child becomes unusually moody or tearful after a head impact, don’t dismiss it.
3. Difficulty Concentrating or “Fogginess”
A child who struggles to follow a conversation, loses their train of thought easily, or seems to be mentally “lagging” may be experiencing post-concussion cognitive symptoms. This is particularly easy to overlook in children who don’t play contact sports — any fall, collision, or head impact can cause it.
4. Light and Noise Sensitivity
Photophobia (sensitivity to light) and phonophobia (sensitivity to sound) are hallmark concussion symptoms that children often don’t report spontaneously. Ask specifically: “Does bright light bother your eyes? Does loud noise feel worse than usual?”
When to Seek Immediate Care
Go to the ER immediately if: a child loses consciousness (even briefly), has a seizure, shows worsening headache, repeated vomiting, one pupil larger than the other, weakness in arms or legs, or slurred speech.
