New research suggests that girls who suffer a concussion may have more severe symptoms that last longer compared to boys.
No one seems to know why there is a difference, but other studies have come to the same conclusion.
"There have been several studies suggesting there are differences between boys and girls as far as [concussion] symptom reporting and the duration of symptoms," said Dr. Shayne Fehr, a pediatric sports medicine specialist at Children's Hospital of Wisconsin.
In his new study, Fehr also found those differences. He tracked 549 patients, including 235 girls, who sought treatment at a pediatric concussion clinic.
Compared to the boys, the girls reported more severe symptoms and took nearly 22 more days to recover, said Fehr, also an assistant professor of pediatric orthopedics at the Medical College of Wisconsin.
In the new study, Fehr tracked patients from 10 to 18 years old. All were treated between early 2010 and mid-2012. Each patient reported on their symptoms, how severe they were and how long it took from the time of the injury until they were symptom-free.
Girls reported more severe symptoms and took an average of 56 days to be symptom-free. In comparison, the boys took 34 days. Overall, the time to recovery was 44 days when boys and girls were pooled.
The length of time it took for patients to fully recover from concussion is quite a bit longer than people usually think.
"Commonly you hear that seven to 10 days [for recovery] is average," Fehr said.
The patient's who were part of this study went to concussion clinics, so their injuries may have been more acute.
Fehr did not find age to be linked with severity of symptoms. Most of the injuries -- 76 percent -- were sports-related, with football accounting for 22 percent of the concussions.
The top five reported symptoms were headache, trouble concentrating, sensitivity to light, sensitivity to sound and dizziness. Boys and girls, in general, reported the same types of symptoms, Fehr said, but the girls reported more severity and for a longer time period.
Fehr will present the findings at the American Medical Society for Sports Medicine this week. Studies presented at medical meetings are typically viewed as preliminary until published in a peer-reviewed journal.
Whether it's a boy or a girl that suffers a concussion, it's important to be seen by a doctor and not return to play prematurely, which can be dangerous or even fatal, according to the American Academy of Pediatrics.
Anyone with a history of concussion is also at higher risk for another injury.
