NASCAR Legend Fred Lorenzen Becomes First Known Driver Diagnosed with CTE

NASCAR icon Fred Lorenzen has made headlines posthumously as the first documented case of Chronic Traumatic Encephalopathy (CTE) in a NASCAR driver. The news follows Lorenzen’s passing at the age of 89 on 18 December 2024, after a long battle with dementia that lasted two decades.

Researchers at the Boston University CTE Center confirmed the diagnosis of stage 3 CTE after analyzing Lorenzen’s brain tissue. The diagnosis was made possible by his family, who shared the findings of the post-mortem analysis with the Concussion & CTE Foundation. Their decision to participate in the research underlines a growing awareness of the long-term effects of head injuries in athletes.

Lorenzen’s contributions to NASCAR were monumental, and his legacy continues to resonate within the motorsport community. He achieved the remarkable feat of being the first driver in the history of NASCAR to earn $100,000 in a single season, a milestone he reached in 1965. That same year, he drove his No. 28 Holman-Moody Ford to victory in the prestigious Daytona 500.

In addition to his racing achievements, Lorenzen was a beloved figure, earning the title of NASCAR’s Most Popular Driver in 1963 and again in 1965. His time in the sport culminated with his induction into the NASCAR Hall of Fame in 2015, recognising his significant impact on the sport and its fans.

Inspired by their father’s struggles and the insights gained from his diagnosis, Lorenzen’s children, Chris and Amanda, have taken steps to improve the quality of care for current and future drivers who may suffer from concussion-related issues. They have launched the Fred Lorenzen Memorial HelpLine as part of the Concussion & CTE Foundation, accompanied by a generous donation of $1 million. This initiative aims to provide assistance to drivers and their families seeking medical support and resources related to head injuries.

CTE is a progressive brain disease caused by repetitive head trauma, primarily affecting athletes in contact sports, including football and various motor racing disciplines. The condition can only be definitively diagnosed post-mortem, which complicates the understanding of its prevalence among living athletes. The Boston University CTE Center reports that the disease has been found in a significant number of examined former NFL players and other high-contact sports participants.

The recent diagnosis of Lorenzen adds to a growing list of athletes whose legacies have been tainted by CTE. In the NFL, a number of high-profile players have also been diagnosed after their deaths. For instance, Steve McMichael and Billy Ray Smith Jr. are among the recent NFL legends confirmed to have CTE. Their cases highlight the urgent need for increased awareness and research into the impacts of concussions in all sports.

Following the tragic 2025 death by suicide of Dallas Cowboys player Marshawn Kneeland, a diagnosis of stage 1 CTE was also made public, further amplifying discussions around brain health among athletes. These incidents underscore the importance of robust preventative measures and treatment protocols to protect athletes’ long-term well-being.

Fred Lorenzen’s story serves not only as a reminder of the risks associated with professional sports but also highlights the vital work being done to address these issues. With initiatives like the Fred Lorenzen Memorial HelpLine, there is hope for increased awareness and support for those affected by similar challenges in the future. As more athletes are diagnosed with CTE, the drive for comprehensive solutions will only grow, encouraging further dialogue and research on the subject.
