Although the symptoms of CTE can vary, it doesn't directly cause death but instead changes personality and behavior, making a person not feel like themselves anymore. Players with CTE can become isolated from their friends. Some players and those around them deal with their violent mood swings, rage, In some cases, damage to players' brains contributes to severe alcoholism leading to death. Two former
NFL Man of the Year winners suffering from CTE symptoms have committed suicide by shooting themselves in the chest, with the intent of leaving their brains intact to be studied for the damage inflicted by football.
Heisman Trophy winner and former NFL All-Pro
Bo Jackson said in a 2017 interview with
USA Today that if he had known about the risks associated with CTE, he would never have played football, and he discourages his children from doing so. In late 2017, former running back
Larry Johnson, who holds the NFL record for most rushing attempts in a season, reported having symptoms akin to
Aaron Hernandez, including memory blanks, suicidal thoughts and thoughts of committing violent acts. Although there is no way to positively diagnose CTE before death, Johnson believes he is living with the disease. The CEO of the Concussion Legacy Foundation states that "[l]ater stage CTE (stage 3 and 4) is associated with dementia, but early-stage CTE (stage 1 and 2) is more associated with what is called neurobehavioral dysregulation, which includes violent, impulsive, or explosive behavior, inappropriate behavior, aggression, rage, 'short fuse,' and lack of behavioral control." Each year of playing tackle football increases a player's risk of developing CTE by 30 percent. Family members and friends frequently struggle to try and provide care for former players with CTE, and not using basic tests to identify dementia in former players for its legal settlement. ==List==
