Question

another knowledge check, which means another chance to score some points! which of the following statements about recurring concussions is true? remember, you earn points for right answers, and you need at least 80 points to pass. after you fully recover from a concussion, its harder to get a second concussion. even if you fully heal between them, multiple concussions can cause long - term brain changes. getting a second concussion after recovering from your first is just as risky as getting a second concussion before recovering from your first. its impossible to fully heal from a concussion — theres always some residual damage.

Explanation:

Multiple concussions, even with full - healing in between, can lead to long - term brain changes due to cumulative effects on brain tissue and neural function. After a concussion, the brain is more vulnerable, so it's not harder to get a second one. Also, getting a second concussion before full recovery is more dangerous than after full recovery. And it is possible to fully recover from a concussion in many cases.

Answer:

Even if you fully heal between them, multiple concussions can cause long - term brain changes.
