Which symptom is NOT commonly associated with a concussion in children?

Feeling energetic is not a symptom commonly associated with a concussion in children. After a concussion, individuals typically experience various symptoms due to the brain's response to injury. Common symptoms include headaches, dizziness, and sensitivity to light as the brain may struggle to process sensory information. These symptoms indicate that the brain is not functioning normally after the injury.

Conversely, feeling energetic contradicts the typical effects of a concussion, which often lead to fatigue, confusion, and a general sense of being unwell. Recovery from a concussion generally involves a reduction in activity until symptoms resolve, as overstimulation can exacerbate feelings of lethargy and other concussion symptoms.
