Final Answer:
B. Lead to permanent brain damage.
Experiencing a repeat concussion before allowing full recovery can result in permanent cognitive damage, emphasizing the critical importance of proper concussion management.
Step-by-step explanation:
Experiencing a repeat concussion before the brain has had the opportunity to recover from the initial injury poses a significant risk of permanent brain damage. Concussions involve the brain undergoing trauma, and allowing adequate time for recovery is paramount in preventing lasting consequences.
When an individual sustains a concussion, the brain goes through a series of physiological changes. The initial impact can disrupt normal brain function, leading to symptoms such as headache, dizziness, and cognitive impairment. Allowing the brain sufficient time to heal is crucial for preventing further damage and minimizing the risk of long-term consequences.
If a subsequent concussion occurs before the brain has fully healed, the cumulative effect can be severe, potentially resulting in permanent damage to cognitive functions. This underscores the importance of proper management and the implementation of protocols that prioritize sufficient recovery time between successive concussions.
