Concussion Symptoms Can Differ for Boys and Girls
TUESDAY, Dec. 7 (HealthDay News) — Among high school athletes,
girls who suffer concussions may have different symptoms than boys, a new
study finds.
The findings suggest that boys are more likely to report amnesia and
confusion/disorientation, whereas girls tend to report drowsiness and
greater sensitivity to noise more often.
“The take-home message is that coaches, parents, athletic trainers, and
physicians must be observant for all signs and symptoms of concussion, and
should recognize that young male and female athletes may present with
different symptoms,” said R. Dawn Comstock, an author of the study and an
associate professor of pediatrics at the Ohio State University College of
Medicine in Columbus.
The findings are slated to be presented Tuesday at the National
Athletic Trainers’ Association’s (NATA) second Youth Sports Safety Summit
in Washington, D.C.
More than 60,000 brain injuries occur among high school athletes every
year, according to the U.S. Centers for Disease Control and Prevention.
Although more males than females participate in sports, female athletes
are more likely to suffer sports-related concussions, the researchers
note. For instance, girls who play high school soccer suffer almost 40
percent more concussions than their male counterparts, according to
NATA.
The findings suggest that girls who suffer concussions might sometimes
go undiagnosed since symptoms such as drowsiness or sensitivity to noise
“may be overlooked on sideline assessments or they may be attributed to
other conditions,” Comstock said.
For the study, Comstock and her co-authors at the University of
Virginia, Charlottesville, and the University of California, Santa
Barbara, examined data from an Internet-based surveillance system for high
school sports-related injuries. The researchers looked at concussions
involved in interscholastic sports practice or competition in nine sports
(boys’ football, soccer, basketball, wrestling and baseball and girls’
soccer, volleyball, basketball and softball) during the 2005-2006 and
2006-2007 school years at a representative sample of 100 high schools.
During that time, 812 concussions (610 in boys and 202 in girls) were
reported.
In addition to noting the prevalence of each reported symptom among
males and females, the researchers compared the total number of symptoms,
the time it took for symptoms to resolve, and how soon the athletes were
allowed to return to play. Based on previous studies, the researchers
thought that girls would report more concussion symptoms, would have to
wait longer for symptoms to resolve, and would take longer to return to
play. However, there was no gender difference in those three areas.
During the first year of the study, the surveillance system included
only the primary concussion symptom for each athlete. In the second year,
high school athletic trainers were able to record all the symptoms
reported by the concussed athlete.
In both years, headache was the most commonly reported symptom and no
difference was noted between the sexes. However, in year one, 13 percent
of the males reported confusion/disorientation as their primary symptom
versus 6 percent of the girls. Also in the first year, amnesia was the
primary symptom of 9 percent of the males but only 3 percent of the
females.
In the second year, amnesia and confusion/disorientation continued to
be more common among males than females. In addition, 31 percent of the
concussed females complained of drowsiness versus 20 percent of the males,
and 14 percent of the females said they were sensitive to noise, compared
with just 5 percent of the males.
Concussion researcher Gerard A. Gioia, chief of pediatric
neuropsychology at Children’s National Medical Center in Washington, D.C.,
called the findings “relatively subtle” and “at best
hypothesis-generating, meaning they are suggestive but in no way
conclusive.”
Gioia said one of the study’s limitations is that the reporting system
didn’t explain about how the injuries occurred. “The presence of
increased amnesia and confusion, two early injury characteristics, in the
males suggests that the injuries between the males and females may have
been different,” he said.
Future studies will likely address this theory, said Comstock, now that
the surveillance system has been expanded to include much more detailed
information. Preliminary data suggest, for instance, that football players
tend to get hit on the front of the head, while girls who play soccer or
basketball often suffer a blow to the side of the head, she said.
The findings will also be published in the January issue of the
Journal of Athletic Training.
