What are classic signs of a concussion in athletes?

Classic signs of a concussion in athletes include confusion and headaches. Confusion manifests as a lack of clarity or disorientation, where the athlete may be unsure of their surroundings, have difficulty concentrating, or may not remember the specifics of the event that led to the concussion. Headaches are a common symptom following a concussion because the brain may become sensitive to stimuli, or there can be direct trauma affecting cerebral function. These symptoms often arise from the injury to the brain and its physiological effects, making them crucial indicators of a concussion.

In contrast, symptoms such as increased strength and agility do not correlate with a concussion. Rather, a concussion typically results in a decrease in physical and cognitive capabilities. Nausea and extreme fatigue can be associated with concussions, but confusion and headaches are more specifically recognized as classic signs. Severe muscle cramps are not related to concussive injuries and suggest different medical concerns not directly linked to brain function.
