Concussion is best described as which of the following?

Brain Bruise With Possible Bleeding And Swelling Brain Injury From External Force Direct Damage At Moment Of Impact Mild TBI With Temporary Neurologic Dysfunction

Correct Answer:

Mild TBI With Temporary Neurologic Dysfunction

Explanation:

Concussion is a mild traumatic brain injury causing a temporary disruption of brain function from a biomechanical force to the head or neck. This functional disturbance can manifest as confusion, amnesia, dizziness, headache, or brief loss of consciousness, and imaging often shows no structural damage. It is not simply a brain bruise with bleeding and swelling, which reflects a more focal, structural injury, nor does it require direct damage at the moment of impact; concussions can result from rapid acceleration–deceleration and diffuse neuronal disruption rather than a single focal lesion.
