Patient's question:
NoDoctor's answer:
Concussion refers to a temporary brain dysfunction that occurs immediately after the head is struck by external force. The pathological changes are not significant, and the mechanism of occurrence is still debated. Clinical manifestations include transient loss of consciousness, retrograde amnesia, as well as symptoms such as headache, nausea, and vomiting. Neurological examinations do not reveal any positive signs, and there are generally no long-term sequelae. Treatment typically involves rest, appropriate energy supplementation, and increased fluid intake.
