Study finds AFL players with concussion likely returning to play with damaged brain cells
A five-year study has found AFL players are likely returning to play from concussion with high levels of damaged brain cells, putting them at risk of long-term harm, even though they might feel fine.
Key points:
- The research shows concussion effects last longer than previously thought
- Some players may be returning before their brain has recovered
- Researchers believe tests for a protein in the blood could determine when a player is safe to return to play
The Monash University study of concussed Aussie Rules players found on average they showed no ill symptoms after a week.
However, analysis of their blood showed their brains had released elevated levels of the protein Neurofilament light (NfL), which is evidence of damaged brain cells.
