Mr Karl Zimmerman, lead author of the research, from Imperial’s Department of Brain Sciences, said: “The implications on an individual level of the brain changes associated with elite rugby participation are unclear, although obviously it is concerning to see these changes in some of the players’ brains. It is important to note that our results in adult professional rugby union and league players are not directly comparable to those who play at local or youth levels. The overall health benefit of participating in sports and physical exercise have been well established including the reduction in mortality and chronic diseases such as dementia. Long-term studies are now needed of both active and retired rugby players to investigate the effect of participation on long-term brain health.”
Dr Simon Kemp, Medical Services Director at the Rugby Football Union (RFU) added: “The RFU is fully committed to advancing our understanding of the short, medium and long term consequences of head impacts and concussions so that we can ensure we can make continued improvements in player welfare. We welcome any research that helps to advance our knowledge which is why we actively collaborated with the academic institutions on the Drake Foundation Rugby Biomarker Study from its inception, particularly to promote the recruitment of players.

While it is unclear from that research what the individual long-term implications are regarding the brain changes seen in these advanced imaging techniques, it is clearly a priority to investigate this further. To further develop our understanding the RFU, in partnership with Premiership Rugby and independent experts, will be providing a specialist clinical service for the assessment and management of retired elite male and female rugby players between the ages of 30-55 to individually assess their brain health.
An integrated research programme will review the risk, causes, assessment and management of brain problems for those who have participated in elite rugby.”
The study was carried out in collaboration with UCL researchers Dr Etienne Laverse and Professor Huw Morris from the Department of Clinical and Movement Neuroscience, UCL Queen Square Institute of Neurology.
Professor Huw Morris said: “We have more to learn about the mechanisms and consequences of head injury, and the best approaches to player assessment. This Imperial/UCL collaborative study has brought together expertise from brain sciences across London.
The Drake Foundation have pioneered work in this field in the UK and we are very grateful for the support of the foundation, players, medical teams, clubs and the RFU in carrying out this work. We hope that this work, and understanding the long-term implications will ultimately improve safety across contact sports.”
