Thank you for publishing the article on concussions in youth sports ("Teen athletes suffer long-term effects of concussions," Sept. 12). It was long overdue. This is a serious problem, and everyone who loves sports and is involved in helping young people to participate should be aware of the risks.
As a neuropsychologist who has worked in concussions for years, I felt that the one area your article did not sufficiently stress was the danger inherent in repeated concussions. The injuries tend to be cumulative, and after each concussion the next is typically easier to get and worse than the one that precedes it.
