The study, WebMD reports, suggests that children who have difficulties in school post-concussion are likely suffering from visual impairments.
276 children with persisting concussion symptoms were examined in the study, each between 5 and 18 years old. 46% of the children participating in the study reported vision difficulties, 26% reported academic difficulties.
The study suggests that the majority of children recover from concussions within around a week/week and a half; however, some children have symptoms persisting longer than the normal recovery time. Children with continued symptoms often suffer academically as a result.
The improvement of protocols involving concussions in children is becoming increasingly important due the increasing rate of head injuries in minors. The U.S. Centers for Disease Control and Prevention estimates that the rate of traumatic brain injuries in minors has doubled from 2001 to 2009.
Dr. Mark Swanson, associate professor and the University of Alabama at Birmingham School of Optometry, states that physicians treating concussed children often overlook vision, and warns that parents and physicians be more vigilant.
