Ruby lawsuits over brain damage could be tip of huge iceberg

Rugby players are suing governing bodies after being diagnosed with degenerative brain diseases, including early onset dementia and probable CTE. Key figures like Steve Thompson, Michael Littman, and Alex Popham are involved, with Thompson unable to recall playing in the 2003 Rugby World Cup. The lawsuit involves nine former players, with over 100 others showing interest due to neurological symptoms. CTE, a progressive brain disease from repeated head impacts, is central to the case.
