What is CTE? How a Washington Law Shook the NFL

Understanding CTE and Its Impact on Athletes

Chronic Traumatic Encephalopathy (CTE) is a progressive brain disease that has recently gained significant attention due to its association with repeated head injuries. This condition, which can lead to severe cognitive and behavioral issues, has been linked to various sports and activities involving frequent head impacts. The recent tragic incident in New York, where a suspect allegedly believed he had CTE and blamed the NFL for his injury, highlights the ongoing conversation around this serious health concern.

What Is CTE?

CTE stands for chronic traumatic encephalopathy, a condition that results from repeated head injuries. According to the Mayo Clinic, these injuries can damage nerve cells in the brain, leading to long-term deterioration. The Cleveland Clinic notes that CTE worsens over time and can affect how the brain functions. While the exact causes are still under study, research suggests that repeated concussions or subconcussive hits may contribute to the development of CTE.

The awareness surrounding CTE has increased significantly in recent years, particularly as more people connect contact sports like football to long-term health consequences. This growing recognition has led to greater efforts to understand and mitigate the risks associated with head injuries.

Washington State's Role in Addressing Brain Injuries

Washington state has played a pivotal role in addressing the risks of traumatic brain injuries in youth sports. In 2009, the state passed the "Zackery Lystedt Law," named after a middle school football player who suffered a catastrophic brain injury in 2006. This law established guidelines for concussion education and protocols for student athletes who experience head injuries during practice or games.

Under the law, athletes, parents, and coaches must receive annual education about the dangers of concussions. It also mandates that players suspected of having a head injury be removed from play and not allowed to return until cleared by a licensed healthcare professional. The law was the first comprehensive mandate in the U.S. aimed at reducing concussion risk and protecting student athletes.

This initiative received support from the Sports Institute at UW Medicine and even caught the attention of the NFL. In 2010, NFL Commissioner Roger Goodell sent a letter to 44 state governors urging them to adopt similar laws. He emphasized the importance of raising awareness and ensuring proper treatment for head injuries.

The Evolution of Concussion Laws

Following the enactment of Washington’s law, studies showed improvements in concussion management. Coaches became more knowledgeable about concussions, and documentation of such incidents increased. The rate of recurrent concussions also declined. By 2014, all states and the District of Columbia had adopted sports concussion laws, according to the National Federation of State High School Associations.

Diagnosing CTE

Currently, the only definitive way to diagnose CTE is through an autopsy. The Mayo Clinic explains that the brain must be examined posthumously to confirm the presence of the disease. Symptoms of CTE can resemble those of other conditions, such as Alzheimer’s disease, making it challenging to identify in living individuals.

According to Boston University in 2023, the Boston University CTE Center diagnosed 345 former NFL players with CTE out of 376 studied. This data underscores the prevalence of the condition among professional athletes.

Causes and Risk Factors

CTE is commonly associated with sports that involve repeated head impacts, such as football, boxing, and hockey. However, other activities, including military service, can also increase the risk. The Cleveland Clinic notes that these sports and activities can lead to multiple head injuries, which may contribute to the development of CTE.

Harvard Health states that there is strong evidence connecting CTE to repeated head impacts, whether or not they result in concussions. However, the reason why some individuals develop CTE while others do not remains unclear.

Symptoms of CTE

Individuals with CTE may experience a range of symptoms, including cognitive, behavioral, mood, and movement changes. These can include difficulty with walking or balance, memory problems, and emotional instability. The Mayo Clinic emphasizes that these symptoms can vary widely and often worsen over time.

As research continues, the focus remains on improving prevention, early detection, and treatment options for those affected by CTE. The lessons learned from Washington state’s proactive approach serve as a model for other regions seeking to protect young athletes from the long-term consequences of head injuries.
