Brentwood students publish concussion study

A neuroscience study led by high school students at Brentwood College School has been published in Scientific Reports a well-recognized and peer-reviewed journal. The research explores the effects of subconcussive impacts in high school sports on brain function.

Brentwood students from the BRAIN (Brentwood Research Action & Innovation in Neuroscience) club worked with leading brain health researchers from Canada and the U.S.

The study — co-authored in collaboration with scientists and clinicians from institutions including Simon Fraser University, HealthTech Connex, Sanford Clinic, Mayo Clinic, Columbia University, and the Atria Academy of Science and Medicine — used portable brain-scanning technology to measure cognitive brain function in 89 high school athletes across 231 scans. Results showed that athletes in high-contact sports had delayed cognitive and auditory responses compared to peers in low-contact sports.

Female athletes had significantly larger disruptions in attention and cognitive processing, raising questions about sports safety and gender-specific health outcomes.

“This is not your typical high school science project,” said Brentwood alumnus Dr. Ryan D’Arcy, the study’s senior author, now a professor at Simon Fraser University. “These students worked on a world-class research project with internationally renowned clinicians and scientists—and proved just how much young minds can accomplish.”

The project began in September 2021 under retired Brentwood science teacher David McCarthy’s mentorship. Today, the BRAIN club continues under science technician Lily Stewart and has completed nearly 500 brain scans involving more than 180 students.

“They were involved in every aspect — from inception to final reporting,” said McCarthy. “This shows what’s possible when young scientists are given the tools and mentorship to thrive.”

Student participants gained valuable experience.

“I’m a really big STEM girl and I want to pursue a career in medicine," said Grade 11 student Nana Li. "This gave me a chance to explore neuroscience and collaborate with like-minded peers.”

“Not many high school students get to do research that actually helps people. It’s hands-on training for university and beyond,” added Jayden Ng, a Grade 12 student.
