The Boston University study reveals a direct correlation between the length of an ice hockey career and the likelihood of developing CTE, with over half of the players examined showing signs of the disease.
The study demonstrated that all but one of the 28 ex-professional players and 18 of 19 NHL players exhibited CTE, significantly more than those who played at lower levels.
Dr. Jesse Mez highlighted that the understanding of CTE in hockey is still developing, with most previous knowledge stemming from research on football players.
The research faced potential selection bias, as families choosing to donate brains may have had prior knowledge of symptoms associated with CTE, indicating a need for broader studies.
