Non-concussion Head Impacts In Contact Sports Could Result In Lower Test Scores

Non-concussion head impacts in sports that involve physical contact as normal play can lead to brain changes and result in lower test scores, a new study suggests.

Based on a recent study, repeated blows to the head during a season of contact sports such as football, hockey or boxing, may cause changes in the brain's white matter - tissue that contain nerve fibers -  and affect cognitive abilities even if none of the impacts resulted in a concussion.

 Researchers at the Indiana University School of Medicine and the Geisel School of Medicine at Dartmouth College found significant differences in the brain white matter of varsity football and hockey players compared with a group of non-contact sport athletes following one season of competition.

"The contact sports and non-contact sports groups differed, and the number of times the contact sports participants were hit, and the magnitude of the hits they sustained, were correlated with changes in the white matter measures," Thomas W. McAllister, M.D., chair of Indiana University's Department of Psychiatry, said in a statement.

Researchers also found that head impact in contact sports may also affect an athlete's performance.

"In addition, there was a group of contact sports athletes who didn't do as well as predicted on tests of learning and memory at the end of the season, and we found that the amount of change in the white matter measures was greater in this group," McAllister said

Children May Need Gradual Transition Back to Academics After Concussion

The American Academy of Pediatrics claims that once a child has a concussion, he or she may need a gradual transition back to school and academic classes.

A concussion should not only take a student athlete off the playing field -- it may also require a break from the classroom, according to a new clinical report from the American Academy of Pediatrics (AAP).

In the clinical report, "Returning to Learning Following a Concussion," released Sunday, Oct. 27 at the AAP National Conference & Exhibition in Orlando, the AAP offers guidance to pediatricians caring for children and adolescents after suffering a concussion.

"Students appear physically normal after a concussion, so it may be difficult for teachers and administrators to understand the extent of the child's injuries and recognize the potential need for academic adjustments," said Mark Halstead, MD, FAAP, a lead author of the clinical report. "But we know that children who've had a concussion may have trouble learning new material and remembering what they've learned, and returning to academics may worsen concussion symptoms."

Research has shown that a school-aged student usually recovers from a concussion within three weeks. If symptoms are severe, some students may need to stay home from school after a concussion. If symptoms or mild or tolerable, the parent may consider returning him or her to school, perhaps with some adjustments. Students with severe or prolonged symptoms lasting more than 3 weeks may require more formalized academic accommodations.

The AAP recommends a collaborative team approach to help a student recovering from a concussion. This team should consist of the child or adolescent's pediatrician, family members and individuals at the child's school responsible for both the student's academic schedule and physical activity. Detailed guidance on returning to sports and physical activities is contained in the 2010 AAP clinical report, "Sport-Related Concussion in Children and Adolescents."

A symptom checklist can help evaluate what symptoms the student is experiencing, and how severe they are.

"Every concussion is unique and symptoms will vary from student to student, so managing a student's return to the classroom will require an individualized approach," said Dr. Halstead. "The goal is to minimize disruptions to the student's life and return the student to school as soon as possible, and as symptoms improve, to increase the student's social, mental and physical activities."

Because relatively little research has been conducted on how concussion affects students' learning, the AAP based its report primarily on expert opinion and adapted it from a concussion management program developed at the Rocky Mountain Hospital for Children, Center for Concussion in Denver, Colo. The AAP calls for further research on the effects and role of cognitive rest after concussion to improve understanding of the best ways to help a student recovering from a concussion.
