Which grading of concussion indicates confusion without loss of consciousness for greater than 15 minutes?

Concussions are classified into grades based on the severity of the injury and the symptoms presented. In this context, Grade II concussions are characterized by confusion that lasts longer than 15 minutes without loss of consciousness. This is a critical distinction because it provides insight into the duration and severity of cognitive impairment following the injury.

Grade II concussions may involve symptoms such as disorientation, amnesia, and balance disturbances, but do not include a complete loss of consciousness, which helps delineate them from higher-grade classifications.

Grade I concussions involve symptoms that resolve in less than 15 minutes and typically do not include confusion as a lasting symptom. Grade III concussions typically encompass any unconsciousness, regardless of duration, and may present with more severe symptoms. Grade IV is not typically recognized in standard grading systems for concussions and would not be applicable in this scenario.

The identification and understanding of these grades are crucial for proper management, recovery expectations, and return-to-play decisions in athletes and patients following a head injury.
