NFL Security Modifications Might Cut back Concussions, however Not the Variety of Hits
The Nationwide Soccer League has made plenty of modifications through the years to scale back concussions, together with rule modifications, penalties for sure dangerous hits, and higher protecting gear, says James Kelly, MD, a professor emeritus of neurology on the College of Colorado Anschutz in Aurora and the chief medical scientist for the Invisible Wounds Basis, who wasn’t concerned within the examine.
Modifications embody:
- Helmet Guidelines Gamers are penalized for decreasing their head to make forceful contact with their helmet, or for utilizing any a part of the helmet or face masks to hit an opponent’s head or neck.
- Guardian Caps These delicate, padded shells match over the helmet to reduce the drive of hits. Gamers in positions with essentially the most head contact should put on them throughout full-contact practices.
- A New Kickoff In 2024, the league modified how kickoffs work, lining up gamers nearer collectively and preserving most of them nonetheless till the ball is caught or hits the bottom, to scale back accidents on the play. The concussion fee on kickoffs has remained under the speed noticed below the outdated format, in keeping with the league.
- Higher Helmets Greater than 98 p.c of gamers now put on helmets that rank the very best in league lab testing for lowering the drive of blows to the top, in contrast with about 70 p.c earlier than the 2025 season started.
However concussions (head accidents that trigger signs) aren’t the perfect measure of CTE threat, says Tripodis. As a substitute, CTE is linked to the entire variety of hits over time, together with the numerous that by no means trigger a concussion, he says.
“Tools comparable to Guardian Caps might reduce the drive of some impacts, but it surely doesn’t scale back what number of hits a participant takes,” he says. Insurance policies that restrict full-contact observe in any respect ranges of play might considerably scale back the danger, he says.
The proof that Guardian Caps shield gamers is controversial, says Dr. Kelly. Even the NFL’s personal information suggests {that a} drop in concussions couldn’t be attributed to the caps alone, he says.
About 4 in 10 of the gamers within the new examine have been 80 or older after they died, so many possible performed lengthy earlier than the league’s current security modifications.
Strengths and Limitations of the Examine
The estimates held up throughout many various assumptions about who donates, the authors wrote.
Nonetheless, the researchers needed to depend on stand-in metrics to evaluate which non-donor gamers had signs, together with whether or not dementia was listed on dying certificates, as a result of it is typically left off.
The examine’s outcomes are a statistical estimate for gamers whose brains have been by no means examined, not a direct depend, says Kelly. “So it’s actually an elaborate methodology of estimation,” he says. He additionally notes that the examine didn’t report different mind illnesses discovered at post-mortem that may trigger dementia, comparable to Alzheimer’s illness.
“I’m unsure this examine contributes considerably to our understanding of the issue,” he says.
Different components that affect mind donation are more durable to measure, says Rachel Grashow, PhD, a senior analysis scientist in environmental well being on the Harvard T.H. Chan College of Public Well being in Boston, who research dwelling former NFL gamers and wasn’t concerned within the examine. For instance, gamers who died by suicide might have hidden or downplayed despair signs round their households, she says.
The outcomes can also’t be utilized to dwelling former gamers. “Those that died earlier who had CTE might have been extra prone to die as a result of CTE-related illnesses, which is probably not reflective of those that will nonetheless reside for a few years,” says Dr. Grashow.
Researchers Need Followers, Gamers, and Mother and father to Perceive the Dangers
“We share these findings in order that present and future gamers perceive the dangers and may work collectively to make the sport safer,” says Tripodis.
As a result of the danger rises with years of play, delaying the beginning of deal with soccer till an older age reduces the entire variety of hits a toddler takes, which might decrease their threat of CTE, he says.
Tripodis additionally desires former gamers to know there are causes for hope. Most of the gamers with CTE at dying possible had early-stage illness, and never all had signs, he says. “We’re making important progress in diagnosing the illness in dwelling folks,” he says.
Grashow and her crew are presently learning about 5,000 dwelling former NFL gamers via Harvard’s Soccer Gamers Well being Examine. They’ve discovered that head accidents increase the danger of a number of treatable situations, together with sleep apnea, low testosterone, hypertension, despair, anxiousness, and ringing within the ears. Left untreated, these situations can hurt the guts and mind, worsen reminiscence and considering issues, and lift the danger of dementia, she says.
As a result of these situations themselves may also trigger cognitive points, former gamers with signs ought to verify with a healthcare supplier about something treatable earlier than assuming they’ve CTE, says Grashow.
Her analysis has additionally discovered that former gamers are particularly weak to despair and suicide, so framing mind illness as inevitable can do actual hurt, she says.
