Which sign is typically NOT associated with a concussion?

A sudden increase in energy is typically not associated with a concussion. Concussions are a type of traumatic brain injury that often lead to symptoms such as confusion, headache, dizziness, and difficulty concentrating. These signs indicate that the brain is affected and struggling to function normally.

In contrast, a sudden boost in energy is not a recognized symptom and may even suggest the opposite of what one would expect following a concussion. After a concussion, individuals usually experience fatigue, lethargy, and cognitive challenges. The presence of confusion, difficulties in focusing, and the experience of headaches or dizziness are all indicative of the brain's response to injury. Understanding these symptoms can help in the assessment and management of concussion cases.
