UTSW scientist hopes delta waves can help doctors, coaches make critical return-to-play decision for athletes.
Elizabeth Davenport hopes delta waves can help doctors, coaches make critical return-to-play decision for athletes.
Elizabeth Davenport and her team identified a brain wave that increased in concussed youth football players compared to non-concussed players.More research is needed to find out whether doctors could someday use this brain wave to measure concussion recovery, according to Benjamin Dunkley, an assistant professor at the University of Toronto and scientist at the Hospital for Sick Children. But it’s a promising start.
“The NFL was just the tip of the iceberg, where there’s 2000, 3000 players,” said Davenport, now an assistant professor of radiology at UT Southwestern. “But then at the youth level, there’s millions of players.”Assistant Professor of Radiology at UT Southwestern, Elizabeth Davenport points to an image of a brain impacted by a concussion at UT Southwestern Clements Imaging Building, Wednesday, Feb. 15, 2023, in Dallas.
. They must also complete a return to play protocol established by the school district’s Concussion Oversight Team.Davenport looked into previous concussion research and found a specific brain wave that spiked during unusual circumstances: delta waves.As we grow older, Davenport said delta waves become less common, except in deep sleep. It’s unusual to see them in the brains of awake adults.that found concussed combat veterans had higher levels of delta waves.
The study adds to existing evidence that delta waves increase following a concussion, and it’s one of only a few that looks at concussions in adolescents and children, said Dunkley at the University of Toronto. He said completing studies with a larger athlete population will be necessary to see how delta waves look in different brains.
