A $20 million federal lawsuit has been filed against the NFL and the New England Patriots on behalf of the former fiancee and daughter of Aaron Hernandez, who committed suicide this year while serving a murder conviction. The lawsuit was filed the same day it was revealed that Hernandez had suffered from chronic traumatic encephalopathy (CTE).Doctors at Boston University studied the brain of the former Patriots tight end and determined that Hernandez had Stage 3 CTE, an advanced form of the neurodegenerative disease. CTE, which can only currently be diagnosed in an autopsy, can be caused by repeated head trauma and leads to symptoms like violent mood swings, depression, and other cognitive difficulties. Hernandez’s CTE was allegedly the most severe case of CTE that the Boston University researchers had ever seen for someone of his age. Advanced stage 3 of CTE is usually found in the median age of 67-year-old men.
Beginning in 2005, a forensic pathologist and neuropathologist found CTE in the brains of diseased NFL players Mike Webster, Terry Long, Andre Waters, Justin Strzelczyk, and Tom McHale. Between 2008 and 2010, the bodies of twelve former professional American football players were diagnosed with CTE postmortem by Dr. Ann McKee.
In 2012, roughly four thousand former NFL players joined civil lawsuits against the League, seeking damages over the League’s failure to protect players from concussions. On August 30, 2013, the NFL reached a $765 million settlement with the former NFL players over their head injuries. According to the settlement, players whose careers concluded before July 2014 gave up the right to sue the NFL unless they opted out. Hernandez’s last NFL game was in January 2013.
