Jugular constriction may reduce concussions

Researchers say the jugular veins that carry blood from the brain to the rest of the body may play an important role in decreasing the number of concussions on the playing field.

In essence, by slightly constricting the bloodflow of the internal veins in the neck -- not the "external" ones exposed in a fit of anger -- a greater cushion of fluid is built up around the brain, helping to shield it from impact.

Dr. Joseph Fisher, from the University of Toronto and the Toronto General Research Institute, and his colleagues, have had their paper accepted for publication by the journal Neurosurgery. Dr. Julian Bailes, neurosurgeon and former team physician with the Pittsbrugh Steelers also contributed.

Noting that helmets do not prevent concussions largely because they don't prevent the brain from moving within the skull upon impact, Dr. Fisher's approach may provide the internal "airbag" that can protect the brain. Constricting the jugular veins may provide enough additional fluid between the skull and the brain to cushion the blows. Laboratory tests have been successful.

Easy to implement

Dr. Fisher wears a pair of special headphones formed to compress his internal jugulars while biking to work. They are no more constrictive than someone wearing a tight collared shirt.

On the field, implementation of his new approach may mean nothing more than a simple collar worn by athletes, or cotton balls attached to hockey players' existing neck gear.

Dr. Fisher already has interest from several Division 1 NCAA teams.
