On September 29, 2009, the New York Times reported on a study commissioned by the National Football League that Alzheimer's disease or similar memory-related diseases appear to have been diagnosed in the league's former players vastly more often than in the national population. According to the report, the rate of dementia is 19 times the normal rate for men between the ages of 30 and 49. The confirmation of the existence of dementia is the league's first public affirmation of the connection to playing football and the development of brain injury-related dementia. The announcement of this finding could have a dramatic effect on safety policies in the area of all sports, not only football, and at all levels, not only professional. Hundreds of on-field concussions are sustained every week at each level and certainly little league, high schools, colleges and professional associations will need to concentrate more thoroughly on the adverse consequences of playing the sport without a maximum amount of protection, prevention, diagnosis and treatment.
