The NFL Players Association is investing in Dementia Discovery Fund, the group that Bill Gates recently made a $100 million investment in.

The DDF is focused on discovering and developing treatments for neurodegenerative diseases, in particular those that are associated with dementia.

“This union has been vigilant about its commitment to the long-term health, safety and well-being of our players,” NFLPA Executive Director DeMaurice Smith said. “For the same reason that we instituted rule changes, concussion protocols and pay for post career neurological benefits, our capital investment in this fund complements our current investment initiatives with the Harvard Football Players Health Study.

“I am proud of the work we do to protect our current and former members and aid the overall health of everyone suffering from neurological conditions.”
