Although the data link to packing is widely admit , the connectedness between CTE and American football was onlypublicly acknowledgedby the NFL in 2016 .
brain doctor have just finished the largest field to engagement look at the brain of former football game players , including many who played for the NFL . Their field was bring out in theJournal of the American Medical Association(JAMA ) on Tuesday .
Out of 202 deceased American football players , 177 were diagnose with CTE . Out of the 111 NFL players , 110 showed sign of CTE . That ’s 99 percent .
The study authors themselves note that the study has " trememndous survival prejudice " and limitation . All of the players in the study had their brains donated for research by their families , so they were perhaps more probable to opt into the study if the players had shown symptoms of CTE . That look at , the number are still startling .
The brainiac included high school football player to NFL caption . Here ’s how the figures die down : 3 of 14 high school players ( 21 percent ) were diagnosed with CTE , 48 of 53 college players ( 91 percent ) , 9 of 14 semi - professional players ( 64 pct ) , 7 of 8 Canadian Football League instrumentalist ( 88 percent ) , and 110 of 111 NFL player ( 99 percentage ) .

Since the link between CTE and contact sports has only been established relatively of late , larger weighing machine field of study such as this are important despite their limitations . Due to spring up cognisance , freshefforts are envision time and money pumped into the study of CTE and sports . Just last year , the NFL put forth $ 100 million for independent aesculapian research into neuroscience - connect topic .
" There are still many unanswered questions refer to the effort , incidence and preponderance of longsighted - condition effects of head trauma such as CTE , " the NFL tell in a assertion in sexual intercourse to this new study .
