Dwayne, a senior in high school, suffers a concussion playing football. Immediately following the event, a typical clinical picture would include:

• A. Brief loss of consciousness and/or amnesia
• B. Confusion and lethargy lasting about 2hrs
• C. Slowed & sometime unequal pupils response
• D. Associated Battle sign

Answer: (A)

Immediately after a concussion, the brain’s function is transiently disrupted, and the most common initial sign is a brief loss of consciousness and/or amnesia for the event. This reflects a temporary interruption of neural processing caused by the head impact. Some athletes may not lose consciousness but will have amnesia for what happened or appear dazed, yet the key feature in the immediate period remains a short-lived disruption of memory or consciousness. The other signs describe either more serious injury or a different mechanism. Confusion and lethargy lasting for several hours isn’t the typical immediate picture of a uncomplicated concussion and suggests more prolonged cognitive impact. Slowed and sometimes unequal pupil response can indicate brainstem involvement or rising pressure, which is not characteristic of a simple concussion. Battle sign points to a basilar skull fracture, a different and more dangerous injury than a concussion.
