Don't know if your interest is specifically soccer, specifically impact damage
or general neurological risks of sport. If the latter you may find interest
in a case report I published a few years ago in the International Journal
of Sports Medicine (I think) raising the possibility of brain damage in judo
players; at the time I ascribed this to an anoxic effect following repeated
strangulation, but one might want to make a case for impact injuries as well
following heavy falls?
