Concussion Cases From Rugby 'Could Be Underestimated'
New evidence has emerged that contact sports such as rugby could be associated with changes in brain structure among players. A study involving a small number of players, published in the journal Brain Communications, found a significant proportion of rugby players had signs of abnormalities to brain white matter, in addition to abnormal changes in white matter volume over time. A research team led by Imperial College London said that further investigation was needed to establish the impact of rugby on brain health.

Neuroimaging evidence of either axonal injury or diffuse vascular injury was seen in 23% of rugby players. The study used two types of MRI called susceptibility weighted imaging and diffusion tensor imaging.
