Repeated rugby concussions may raise brain risks

RUGBY players who suffer repeated concussions could be more likely to suffer brain diseases such as Alzheimer's and motor neurone disease, a study suggests.

They were found to have higher levels of proteins in the blood thought to play a crucial role in the development of the degenerative illnesses.

Scientists searched for biomarkers in samples from 30 retired sportsmen who had experienced more than five concussions in their careers.

Their results were compared with 26 retired players and athletes with no history of head trauma.

Concussed players had more of proteins called serum t-tau and tau-p181 believed to be linked to Alzheimer's and MND and lower levels of a protein called RBP-4 which is involved in the development and functioning of the brain.

The Durham University-led researchers said this method of looking for biomarkers could be used to monitor retired athletes and diagnose neurodegenerative diseases earlier.
