How can you identify if someone may have a concussion?

Identifying a concussion involves recognizing a range of symptoms that may indicate an injury to the brain. The presence of confusion and headache is a hallmark sign of a concussion. Confusion can manifest as a person being unable to remember events immediately before or after the injury, difficulty concentrating, or feeling dazed. Headaches are also very common after a concussion and can vary in intensity. Together, these symptoms suggest that a concussion may have occurred, requiring further evaluation and monitoring for additional signs of impairment.

Visible swelling of the head might suggest a more serious injury, such as a fracture or hematoma, but it is not a definitive indicator of a concussion. Loss of consciousness is often associated with concussions, but it is not necessary for a diagnosis; many people with concussions do not lose consciousness. Constant sneezing and a runny nose are generally associated with allergies or respiratory issues, not brain injuries, making them irrelevant in the context of diagnosing a concussion.
