On Wednesday, NHL commissioner Gary Bettman will appear before a government of Canada parliamentary subcommittee on concussions in sports.

The committee began its hearings in November. It heard, first of all, from athletes — boys, girls, women, men — from many different sports. The athletes talked about their experiences, the brain injuries they suffered, the symptoms they felt, the diagnoses and treatments they received and the life effects they live with — about how their lives have changed and what that means for them and those around them.

It heard from medical people, from researchers who have made the brain their life’s study and doctors who have made the health and well-being of their patients their life’s work, from those who know the most and the best about what is known and isn’t known, about what they are able to do and what they aren’t and what others must do.

It heard from the leaders of other sports, whose job is also to make the decisions that affect the welfare of their players and their games. It asked them what they have done and, more importantly, what they will do to significantly reduce brain injuries in their sport in the future.

Here are some questions the subcommittee might ask Bettman:

1. Is there a connection between chronic traumatic encephalopathy (CTE) and hockey?
