Extensive Hockey Careers May Increase CTE Risk: Study

Chronic traumatic encephalopathy, or CTE, has often been associated with American football. However, a new analysis highlights the dangers faced by ice hockey players.

Despite the focus on football, other contact sports, like ice hockey, haven't received as much investigation regarding brain health risks.

Study Highlights

Boston University researchers have released a substantial study linking the duration of a hockey career to the likelihood of developing CTE.

Published findings showed that over half of the examined hockey players had CTE, and the probability increased with career length.

Research Methods and Findings

The players' brain autopsies, which alone can confirm CTE, were studied. Out of the 77 deceased players, 27 of 28 who had NHL careers manifested CTE symptoms.

Among those who only played through high school or youth leagues, only 10% showed signs of CTE.

Expert Insights

Dr. Jesse Mez of Boston University highlighted that the prominent source of existing knowledge about CTE comes from football, given its extensive sample size.

A selection bias may exist, as individuals who displayed symptoms often opted to donate their brains to science, which complicates general population estimates.

The study doesn't provide precise risks for general players but points out that longer playtime correlates with increased risk.

Current Safety Measures and Opinions

In the last decade and a half, knowledge about head trauma risks has prompted new safety regulations across all hockey levels.

However, NHL commissioner Gary Bettman expressed skepticism about hockey's link to CTE, referring to a lack of conclusive documentation.

He argued that hockey and football are distinct due to differing levels of head contact.

A Deeper Look into Hockey-Specific Risks

Research shows that repeated head impacts in sports cause CTE. Beyond American football and ice hockey, other contact sports including rugby and soccer have also been implicated.

Former hockey player Kerry Goulet noted that certain inherent features, like the hard ice surface and rink borders, make some head impacts unavoidable.

He discussed how the fast-paced nature leads to frequent high-impact collisions, resulting in injuries experienced during active play, which later manifested symptoms linked to brain damage.

Advancements in Safety Practices

Players now training year-round have become larger and stronger, although junior players benefit from increased safety measures.

Significant rule changes, such as penalties for head hits, aim to protect against dangerous play and limit exposure to injury.

The introduction of penalties for head-centric hits has noticeably diminished concussion rates.

Future Actions for Player Security

Dr. Michael Stuart of USA Hockey emphasizes continuing vigilance against aggressive and dangerous play through strict penalties.

Advocating for further safety enhancements, he supports eliminating fights from NHL games to lower risk further.
