THE long-term impact of sport-related concussions can "no longer be ignored", according to the Scotland rugby team doctor.

Dr James Robson has published a report in this month's Clinical Journal of Sport Medicine in which he, along with two other co-authors, calls for a cultural change in the public perception of head injuries in sport.

The paper discusses the long-term cognitive, psychiatric, and neuro-behavioural problems associated with concussion, while highlighting the flippant response to these concerns from the sporting community at large.

It said: "Concussion has long been viewed as a benign occurrence, 'part and parcel' of sport, and for some even considered as a 'badge of honor'.

"Convincing society of the importance of recognising concussion is particularly challenging because most athletes who experience concussion seem to recover without readily apparent consequence."

With a focus on rugby, hockey and other 'collision' sports, the academics outlined the 'life-altering consequences' which could result from the mismanagement of concussive injuries.

The risk of young sportsmen is of particular note as they found that almost half of all rugby players under the age of 20 have sustained a concussion.

Such an injury is now the third most common match injury in amateur and professional rugby.

Though some measures have been put in place to mitigate the impact of serious head injuries, the paper argues that only a substantive cultural shift will safeguard the health of modern sportsmen.

The report added: "Attempts to stem this epidemic, including the wearing of headgear in rugby...have made no difference to the incidence. The key problem is that, until now, concussion has not always been taken seriously enough by players, coaches, and medical staff.'

"Although considerable steps have been taken to improve management and educate all involved, a fundamental cultural change in the perception of this condition is needed."
