Prompt action over concussion leads to faster return to play, study shows

Delaying concussion treatment and failing to take it easy can risk further brain injury and longer recovery times, research suggests.

The University of Florida study found that college athletes who delayed concussion reporting were more likely to be sidelined for longer than those who promptly reported the problem.

The study team found those who delayed treatment or removal from play missed an average of five more days of play than athletes who immediately reported symptoms.

The findings, reported in the May issue of the Journal of Athletic Training, suggest that athletes who don’t receive immediate treatment for concussion risk further insult to the brain and may take longer to recover, said Breton Asken, the study’s lead author.

Asken, a doctoral student in the university’s College of Public Health and Health Professions, said previous research indicated that, during the period after a concussion, intense physical activity, not just direct hits to the head, can be detrimental.

“We believe exertion or increasing blood flow to the brain when it’s not quite ready to handle that, even in the absence of more impacts to the brain, could also interfere with recovery in this window,” said Asken, who is also a clinical and research coordinator for the Sports Concussion Center at the university’s Student Health Care Center.

For the study, researchers examined data from the University of Florida Concussion Databank, which contains concussion-related medical history and injury details for athletes in its varsity sports programs.

The study included 97 male and female athletes participating in basketball, football, gymnastics, lacrosse, soccer, swimming and diving, track and field, and volleyball who were diagnosed with a sport-related concussion between 2008 and 2015.

Of those, 50 did not immediately report concussion symptoms.

When controlling for other factors shown to prolong recovery time, such as a history of concussion or previous diagnosis of a learning disability, attention deficit hyperactivity disorder or depression, the researchers found that athletes who delayed reporting a concussion still took an average of five more days to receive medical clearance to return to play.

“I think many athletes naively believe that concussion symptoms will go away, or if they report a concussion it will keep them out of play for a lot longer,” said senior author Russell Bauer, who is Asken’s mentor and a professor in the department of clinical and health psychology.

He said the data showed that those who delayed reporting a concussion may actually have a longer road back to the playing field.

Future research should examine larger groups of athletes and different ages, including high school players, the researchers said.

Because it was a retrospective study of medical records and notes by team physicians and athletic trainers, the research team was not able to quantify the specific amount of time athletes kept playing before reporting a concussion, whether that was immediately after finishing the game or days later, to determine how the length of a reporting delay contributed to recovery time.

The researchers hope the information will become part of the pre-season education of athletes by trainers and team physicians.

Asken continued: “The acute effects of concussion and what it does to the brain are becoming better understood at this point, but in some cases it is still not enough to convince athletes that it is important to report an injury or remove themselves immediately from play.

“What this study might add is context the athlete can relate to, and that is how much time they may miss from their sport. Immediate reporting of concussion symptoms allows for proper management at the point of injury and gives athletes the best opportunity to return to their sport more quickly.”
