Retired jockeys to take part in concussion study
A new study has been trying to find out the long term effects of concussion on men and women who have competed in contact sports.
Concussion in Sport seeks to establish whether retired sportsmen and sportswomen have an increased incidence, or suffer an earlier onset, of neuro-degenerative disorders.
The initial screening process will focus on retired jockeys - former champion jump jockey Richard Dunwoody is among the first volunteers for the project.
