xvi, 68 p. : ill. / Approximately 1.5 million concussions occur annually in the United States, many affecting individuals between the ages of 15 and 18. Little is known about this age group's response to a concussion as they have been thought to respond differently than adults due to immature brain development. Additionally, relying on symptoms alone to determine level of brain function may lead to early return back to sport participation. Through the use of 3 computerized tests, neuropsychological and attentional deficit recovery post concussion was assessed between 12 subjects with concussions and 12 controls up to 2 months after injury. Memory tasks and symptoms resolved within a week after injury. Executive function tests showed small group differences up to two months post injury, suggesting these types of tests may be a useful tool in the evaluation of concussion recovery and provide an objective measure in evaluation. / Committee in charge: Dr. Li-Shan Chou, Chair; Dr. Lou Osternig, Member; Dr. Sierra Dawson, Member; Dr. Grace Golden, Member
