Which of the following is a symptom of a concussion?

A concussion is a type of traumatic brain injury that can result from a blow to the head or a violent shaking of the head and body. It is important to recognize the symptoms associated with a concussion, as timely intervention can be crucial for effective recovery.

The correct response includes all the identified symptoms—loss of consciousness lasting more than a minute, persistent nausea and vomiting after the injury, and a sudden severe headache after a fall—because they are all potential indicators of a concussion.

Loss of consciousness, even if brief, can be a warning sign of a more serious brain injury. If this lasts longer than a minute, it signifies a more significant impact on the brain. Persistent nausea and vomiting suggest that the brain is struggling to maintain normal function after the injury, and these symptoms are often alarming signs that require immediate medical assessment. Similarly, a sudden severe headache following a head injury may indicate a concussion or other serious conditions, such as intracranial bleeding.

Understanding and recognizing these symptoms is critical for anyone involved in care after a head injury, making it vital to consider all of these potential indicators together.
