What type of concussion results in rapid return to normal cognitive function?

1. Mild diffuse axonal injury

2. Severe diffuse axonal injury

3. Post-concussion syndrome

4. Chronic traumatic encephalopathy

The correct answer is: Mild diffuse axonal injury

The correct choice is linked to the severity and characteristics of different types of concussions and their impact on cognitive function. Mild diffuse axonal injury is associated with a less severe disruption of neuronal connections, generally leading to a quicker recovery of cognitive abilities. In these cases, the individual might experience temporary symptoms—such as confusion, disorientation, or headache—but they typically resolve within a short period, allowing for a rapid return to normal cognitive function. In contrast, severe diffuse axonal injury involves more extensive damage to the brain's structures, often resulting in prolonged periods of unconsciousness or significant cognitive impairment. Post-concussion syndrome is characterized by persistent symptoms long after the initial injury, which may include headaches, dizziness, and cognitive difficulties that can last weeks to months, indicating a much slower recovery. Chronic traumatic encephalopathy involves cumulative damage from repeated head injuries, leading to progressive decline in cognitive function and is not associated with a rapid return to normalcy. Thus, mild diffuse axonal injury aligns with a quicker resolution of symptoms and a swift return to cognitive function, making it the appropriate choice in this context.
