The largest study conducted to date on chronic traumatic encephalopathy has uncovered a new connection between playing contact sports and the onset of the movement disorder known as Parkinson’s Disease.
Chronic traumatic encephalopathy is a degenerative brain disease, with the only known cause being repeated impacts to the head, as seen in contact sports.
A prior study by the same research team in 2018 found that the duration of participation in contact sports was linked to an increased risk of Lewy body disease. However, the current study is the first to illustrate the association between involvement in contact sports, brainstem disease, and Parkinson’s disease in individuals with CTE.
Chronic Traumatic Encephalopathy and Parkinson’s
The research, which analyzed the brains of 481 deceased athletes, was conducted by researchers at Boston University’s Chobanian and Avedissian School of Medicine and the University of Virginia. It was published on July 15 in JAMA Neurology. The findings reveal that most individuals with CTE also have Parkinson’s disease, suggesting that CTE may be the primary cause of Parkinson’s symptoms in many cases.
Parkinson’s disease is characterized by symptoms that include tremors, slowness of movement, and stiffness in the arms or legs. It has long been linked to brain injuries and chronic traumatic encephalopathy, particularly in boxers. However, the underlying pathology responsible for these symptoms in CTE has yet to be clarified.
While Parkinson’s disease is traditionally associated with the accumulation of proteins known as Lewy bodies in brain cells, researchers found that 76 percent of individuals with CTE and Parkinson’s do not exhibit Lewy body disease.
Thor Stein, MD, an associate professor of pathology and laboratory medicine at Boston University and Virginia Health Care, and one of the study’s authors, stated, “We were surprised to find that most of the individuals with CTE and Parkinson’s did not have Lewy body disease.”
“Instead, people with Parkinson’s were more likely to show CTE-related brain cell death in a region of the brainstem that is crucial for movement control,” he added.

Study of Patients’ Brains
The participants in the study donated their brains to a private brain bank aimed at furthering the understanding of neurological injuries and traumatic encephalopathy. Individuals diagnosed with Parkinson’s were compared with those without the disease to identify specific types of pathology that could explain why some individuals with the condition exhibit these symptoms and to explore relationships with the duration of contact sports participation.
Daniel Kirsch, a medical doctoral student at Boston University and one of the researchers involved, noted, “The severity of CTE has been linked to a longer duration of play, and in this study, we found that an additional eight years of contact sports participation was associated with a 50% increased risk of more severe disease in a specific region of the brainstem controlling movement.”
The study underscores the importance of understanding the long-term impacts of recurrent head trauma and highlights the necessity for preventive measures in contact sports to mitigate the risk of neurodegenerative disorders such as chronic traumatic encephalopathy and Parkinson’s disease.

Chronic Traumatic Encephalopathy and Parkinson’s Disease: A Surprising Discovery
The recent research conducted by Boston University School of Medicine highlights a startling connection between Chronic Traumatic Encephalopathy (CTE) and Parkinson’s Disease. This connection emerges from a comprehensive study involving 481 deceased athletes, revealing that a significant number of CTE patients also exhibit symptoms of Parkinson’s Disease. The findings were published on July 15, 2024, in JAMA Neurology.
CTE is a degenerative brain disorder primarily caused by repeated head trauma, making it a serious concern among athletes participating in contact sports such as football, boxing, and hockey. For many years, it has been known that CTE can lead to a wide range of neurological symptoms, including cognitive decline and emotional instability. However, the specific mechanisms linking CTE with Parkinson’s Disease have remained largely obscure.
The Link Between CTE and Parkinson’s Disease
- Reputation of the Findings: The study revealed that the majority of individuals diagnosed with CTE also showed symptoms characteristic of Parkinson’s Disease.
- Brainstem Connection: Researchers found that rather than the expected presence of Lewy body disease, most participants had significant cell death in the brainstem—an area critical for movement control.
- Scope of the Study: This is groundbreaking as it illustrates how longer durations of participation in contact sports may exacerbate these symptoms.
Dr. Thor Stein, a key author of the study, remarked, “We were surprised to find that most of the people with CTE and Parkinson’s did not have Lewy body disease.” This indicates a need for reevaluating how we understand the pathology of Parkinson’s in the context of CTE.
Study Insights: The Examination of Brain Donations
The research relied on brain donations from athletes, who had voluntarily contributed their brains to a specialized brain bank aimed at advancing the understanding of traumatic encephalopathy. The chosen athletes were meticulously compared based on their Parkinson’s status. This approach provided comprehensive insight into how contact sports correlate with neurological decline.
| Contact Sports Duration (Years) | Increased Risk of Severe CTE (%) |
|---|---|
| 8 | 50 |
| Other Durations | Varies |
As per Daniel Kirsch, a doctoral student in medicine at Boston University, “The severity of CTE has been shown to be associated with longer duration of play.” The findings suggest that every additional eight years spent in contact sports could contribute to a 50% increase in the risk of developing a more severe form of CTE, specifically targeting brain regions essential for movement.
Health Implications of CTE and Parkinson’s Disease
The implications of this study are profound. Understanding the connection between CTE and Parkinson’s Disease emphasizes the critical need for preventive measures in contact sports. The rising number of reported cases indicates an urgent requirement for awareness surrounding the long-term impacts of repeated head injuries.
Here are some vital health insights:
- Early Symptoms of CTE: Confusion, memory loss, aggression, and depression can manifest years before CTE is clinically diagnosed.
- Parkinson’s Symptoms: Tremors, stiffness, slowness of movement, altered gait, and balance issues often surface as CTE progresses.
- Risk Management: Implementing strict safety protocols in contact sports can significantly reduce the risk of traumatic brain injuries.
Preventive Measures and Recommendations
To mitigate the risks associated with CTE and Parkinson’s Disease, adhering to the following preventive measures is recommended:
- Educational Programs: Introduce initiatives to educate athletes about the risks of head injuries.
- Rules and Regulations: Ensure that sports organizations enforce rules aimed at reducing head impacts and injuries.
- Regular Health Check-ups: Encourage athletes to undergo regular neurological assessments to catch symptoms early.
- Safe Practice Techniques: Implement training techniques that emphasize safety and injury prevention.
Case Studies: Real-Life Impact
Numerous case studies of athletes with CTE illustrate the poignant impacts of this disorder:
- Case of an Ex-NFL Player: After long years in professional football, a former NFL player suffered severe memory loss and exhibited classic Parkinsonian symptoms, ultimately diagnosed with both CTE and Parkinson’s.
- Boxing Champion’s Struggle: A former boxing champion’s battle with cognitive decline and mobility issues served as a powerful reminder of the toll of repeated head trauma.
These case studies exemplify the importance of awareness and preventive strategies, emphasizing the emotional and psychological repercussions associated with these neurodegenerative diseases.
First-Hand Experiences: Voices from the Affected
Listening to the stories of those affected can provide invaluable insights into the personal toll of these disorders:
- A Family’s Journey: A spouse of a former athlete shared their experience navigating the challenges of CTE and its progression to Parkinson’s, shedding light on the emotional and financial strains.
- Player’s Perspective: A retired hockey player recounts his initial symptoms and lack of understanding of their significance, reinforcing the call for better education and awareness within sports.
Such narratives not only illustrate the impact of CTE and Parkinson’s but also foster greater empathy and understanding within communities.
The intersection of Chronic Traumatic Encephalopathy and Parkinson’s Disease underscores an urgent need for increased awareness. The latest findings from the Boston University School of Medicine challenge existing understandings of both conditions and point towards significant implications for how we approach the safety and health of athletes participating in contact sports.
