Question
The child vomited after hitting his head. I’m worried about possible concussions or other severe consequences.
Answer
A concussion refers to a temporary brain dysfunction that occurs immediately after a blow to the head. There are no obvious changes in pathological anatomy, and the pathogenesis is still controversial. Clinical manifestations include transient unconsciousness, recent memory loss, headaches, nausea, and vomiting, with no positive signs found during neurological examination. Generally, no sequelae occur, and it is usually recommended to rest more, adequately replenish energy, and drink plenty of water.
