John Mackey, Hunter Hillenmeyer, Mike Haynes, Zach Thomas, Kyle Turley to Donate
The Center for the Study of Traumatic Encephalopathy (CSTE) at Boston University School of Medicine (BUSM) announced today that one active and 18 retired National Football League (NFL) players have pledged to join the rapidly growing CSTE Brain Donation Registry. The newest donors are current Chicago Bears linebacker Hunter Hillenmeyer, Hall of Famer Mike Haynes, Pro Bowlers Zach Thomas, Kyle Turley, and Conrad Dobler, NFL Players Association (NFLPA) Senior Regional Director Jason Belser, Super Bowl Champion Don Hasselbeck, Keith Krepfle, and Jack Thompson. In addition, Sylvia Mackey, wife of John Mackey, the Hall of Fame Baltimore Colts tight end suffering from dementia, has pledged to donate Mr. Mackey’s brain upon death.
These NFL players have decided to donate their brain and spinal cord tissue to the CSTE upon death so that researchers can better understand the effects of repeated head trauma on the nervous system and develop strategies for prevention, treatment, and ultimately, a cure. They join a growing list of active players, players such as Matt Birk of the Baltimore Ravens, Lofa Tatupu of the Seattle Seahawks; and Sean Morey of the Arizona Cardinals, and NFL retirees, including Ted Johnson, Joe DeLamielleure, Bruce Laird, Ben Lynch, Brent Boyd, and Bernie Parrish. These players are among the more than 250 current and former athletes, including 60 retired NFL players, in the CSTE Brain Donation Registry.
“The only way we will truly understand the long-term effects of repetitive head trauma in football is to study a large group of athletes throughout their lives and then examine their brains following death. These athletes who are participating in this research are to be commended for their commitment and courage,” stated Dr. Robert Stern, co-director of the CSTE.
Brain trauma in sports is increasingly seen as a public health crisis due to the discovery of a neurodegenerative disease called Chronic Traumatic Encephalopathy (CTE) in a number of recently deceased athletes. CSTE co-director and degenerative brain disease expert Dr. Ann McKee identified CTE in all twelve of former college and NFL players’ brains she studied, including Hall of Famer Lou Creekmur, Wally Hillgenberg, Tom McHale, and John Grimsley. McKee also identified CTE in the only former NHL player examined, Mr. Reggie Fleming.
CTE, originally referred to as “dementia pugilistica” because it was believed to only affect boxers, is a progressive brain disease caused by repetitive trauma to the brain, including concussions and subconcussive blows to the head. It is characterized by the build-up of a toxic protein called tau in the form of neurofibrillary tangles (NFTs) and neuropil threads (NTs) throughout the brain. The abnormal protein initially impairs the normal functioning of the brain and eventually kills brain cells. Early on, CTE sufferers may display clinical symptoms such as memory impairment, emotional instability, erratic behavior, depression and problems with impulse control. However, CTE eventually progresses to full-blown dementia. Although similar to Alzheimer’s disease, CTE is an entirely distinct disease, and it is the only fully preventable cause of dementia. McKee and her colleagues published their research findings on CTE in athletes in the July issue of the Journal of Neuropathology and Experimental Neurology.
The CSTE’s groundbreaking research created a dramatic change in the understanding of and response to brain trauma and concussions in all sports, but especially football. The research contributed to the House Judiciary Committee holding two hearings on head injuries in the NFL in recent months, and CSTE Co-Directors McKee, Dr. Robert Cantu, and Chris Nowinski were invited to testify. Mr. Nowinski recruited many of the donors through the non-profit Sports Legacy Institute, a sports concussion educational and advocacy organization and partner in the BU CSTE. Since then, the NFL has made multiple changes to the way concussions are managed, including requiring an independent neurological specialist to determine when a concussed athlete can return to play, mandating that any player who has symptoms of a concussion not return to play the same day, accepting the resignations of the co-chairs of the NFL Mild Traumatic Brain Injury (TBI) Committee, running public service announcements during NFL games about the danger of concussions, and pledging to support the ongoing research at the BU CSTE.
The NFLPA has pledged to support the CSTE’s research and encourages players to participate. On January 26, the NFLPA held the first meeting of the Mackey/White TBI Committee, which includes CSTE co-directors Cantu, McKee, and Nowinski, and is chaired by CSTE registry member Sean Morey.
The NFLPA Mackey/White Committee was named in honor of John Mackey, a former president of the NFLPA, and Reggie White. It was Sylvia Mackey’s advocacy on her husband’s behalf that led to the NFL’s creation of the “88 Plan”, which has provided over $7 million dollars for care of former NFL players with dementia, and is named after John Mackey’s number 88. Over 100 NFL families have benefitted from this program. Mrs. Mackey said, “It is probably too late for this research to help John, as his dementia has advanced to the point that he cannot speak. However, I hope the CSTE scientists can learn from John so that fewer football families are exposed to this terrible disease.”
Dr. Cantu, a leading sports concussion expert and clinical professor of neurosurgery at BUSM, said, “We are thankful to Mrs. Mackey for her support of our research and for her years of advocacy for the countless retired athletes who suffer from brain diseases like her husband. Because of her support of our research, and because of the growing number of athletes participating in our brain donation registry, we will be able to determine the specific risk factors for CTE and potentially develop effective treatments. The research will foster education and allow meaningful guidelines to be implemented at all levels of athletic participation.”
Chicago Bears linebacker Hillenmeyer said of his decision to donate his brain following death, “I owe it to my fellow active players, the players who came before us, and the millions of college, high school, and youth athletes. It is critical to support this research so we can make sure we truly understand the potential long term risks associated with brain injuries in the NFL and football at all levels.”
Former Miami Dolphins stalwart middle linebacker Zach Thomas stated, “I would like to make sure the game of football survives. The scientific findings to date are clear that repetitive trauma to the head results in CTE in many athletes. I want to do my part to help the researchers understand this disease and to discover treatments and an eventual cure. This is not just about professional athletes who may know there are risks to the game. This is about making sure that the game is safe for all of those children playing the game today and in the future.”
The CSTE was created in 2008 as a collaborative venture between Boston University School of Medicine (BUSM) and Sports Legacy Institute (SLI). The mission of the CSTE is to conduct state-of-the-art research of Chronic Traumatic Encephalopathy, including its neuropathology and pathogenesis, the clinical presentation and course, the genetics and other risk factors for CTE, and ways of preventing and treating this cause of dementia.
Sports Legacy Institute is a 501(c)(3) nonprofit corporation founded in 2007 to solve the sports concussion crisis. SLI is dedicated to education, prevention, treatment, and research on the effects of concussions and other brain injuries in athletes and the military. SLI partnered with Boston University School of Medicine to form the Center for the Study of Traumatic Encephalopathy in 2008.
