Pediatric head trauma occurs when a child bumps their head. Usually, the trauma is minimal and only results in mild symptoms such as a bruise or headache. In other cases, the child may experience symptoms of a concussion such as a loss of consciousness, vomiting or confusion. Concussions usually resolve over a short period of time and are rarely the cause of long term problems. However, if a child experiences multiple concussions, they are at risk for more serious brain damage. In cases of severe head trauma, there may be bleeding in the brain or a skull fracture.
