Researches have found in  that Among 111 players who played in the National Football League (NFL), 99% had CTE. A progressive clinical course was common in players with mild and severe CTE pathology. The results suggest that CTE may be related to prior participation in football, the researchers said.

Most NFL athletes have and live with CTE. Professional athletes are most common of athletes to have  brain trauma and increasing among players every year. In recent finding they have found that most football players just live with minor CTE findings. With football the impact of a solid hit to the head is such a powerful force that could easily put an athlete out for the rest of their career. Most are not willing enough to leave the game tho. Therefore they stay and increase their chances. “In July 2011, Colts tight end John Mackey died after several years of deepening symptoms of frontotemporal dementia. The Boston University School of Medicine BUSM was reported to be planning to examine his brain for signs of CTE. The Brain Bank found CTE in his brain post-mortem.”

Most athletes get out of the National Football league and struggle with brain disorders. More then half of the athletes after the NFL are diagnosed with or shows symptoms of CTE. The NFL try’s to decrease the amount of impact an athlete gets to the head by increasing the rules and ways to tackles, the cushioning in the helmet, and the amount of treatment a person can get.
