Greg and Sesi are joined on the podcast by Dr. Jonathan Hanson, Consultant in Sports & Exercise Medicine, Team doctor for Glasgow Warriors Rugby team and member of the Scottish Government Medical Advisory Group on Sports Concussion. He talks about some of the short, medium and long effects of concussions, the work being done to tackle concussions and head injuries in sports and the general public. Giving the recent spotlight on this, one of his key messages is the need to be cautious and trat head injuries with respect as clinical questions continue over the long term implications.
