Question
A child accidentally fell while walking on the bed and hit the edge of a cabinet at the corner of the head. This resulted in slight swelling and bruising on the left side of the head. The parent inquires whether there is cause for concern and if there might be any residual symptoms.
Answer
A concussion typically refers to a temporary brain dysfunction that occurs immediately after a blow to the head. Although the pathological changes are not apparent, there are many controversies about its mechanism of occurrence. Clinical symptoms include transient unconsciousness, amnesia for recent events, as well as headaches, nausea, and vomiting. Examination usually reveals no abnormalities in the nervous system, and generally, no residual symptoms occur. Treatment recommendations include adequate rest, proper energy supplementation, and drinking plenty of water.
