Dementia pugilistica (DP) The condition is caused by repeated concussive and sub-concussive blows (blows that are below the threshold of force necessary to cause concussion), or both.〔 〕 Because of the concern that boxing may cause DP, there is a movement among medical professionals to ban the sport.〔 Medical professionals have called for such a ban since as early as the 1950s.〔 〕 ==Etymology== The word ''pugilistica'' comes from the Latin root pugil, for ''boxer'' (akin to ''pugnus'' fist, ''pugnāre'' to fight).〔(Pugilism (origin) ), retrieved on 2013-2-2.〕〔NCERx. 2005.
