In a shocking incident on Monday, a gunman opened fire in an office building in Midtown Manhattan, believed to be linked to his struggle with mental health issues stemming from a suspected brain injury, which he attributed to the National Football League (NFL). Shane Tamura, aged 27, a former high school football player, fatally shot four individuals with an assault rifle before taking his own life, leading to a renewed focus on Chronic Traumatic Encephalopathy (CTE) and its impact on athletes.
CTE is a progressive brain disease that arises from repeated head trauma, including both obvious concussions and undetected hits to the head. While definitive diagnoses can only be made post-mortem, symptoms such as aggression and dementia may manifest during a person's life. Studies indicate a strong correlation between CTE and athletes who have played tackle football, whether at amateur or professional levels, with the NFL acknowledging the associated risks.
The NFL came to a notable settlement agreement in 2015, costing around $1 billion, to address thousands of lawsuits concerning concussion-related issues brought forth by retired players. Data from Boston University’s CTE Center revealed that out of nearly 400 former NFL players examined up to 2023, 345 were found to have CTE. According to Dr. Ann McKee, who heads the CTE Center, prolonged exposure to football increases the likelihood of developing this disease.
Although Tamura did not play in the NFL, he was active in high school football until his graduation in 2016. The issue of CTE has been underscored by high-profile cases of former NFL players like Junior Seau, Aaron Hernandez, and Phillip Adams, who all exhibited significant brain injury symptoms linked to their football careers, prompting increased scrutiny on the sport's safety protocols.
To combat the increasing concerns over brain injuries, the NFL has reported a decrease in concussions during the latest season, crediting advancements in helmet technology and some rule modifications. Following considerable backlash over significant head injuries, the NFL also strengthened concussion protocols in 2022. However, experts, including Dr. McKee, argue that these efforts only scratch the surface and highlight the need for a more comprehensive understanding of the effects of asymptomatic head impacts.
Moreover, the threat of CTE is not exclusive to football; other contact sports like rugby, ice hockey, and soccer have also been implicated. Recently, over 1,000 former rugby players in the UK have come forward, alleging that their sport's organizations were negligent in safeguarding them against potential brain injuries, prompting rugby's governing bodies to introduce several measures aimed at improving player safety.
