OBJECTIVE Cerebral concussion is common in collision sports such as football, yet the chronic neurological effects of recurrent concussion are not well understood. The purpose of our study was to investigate the association between previous head injury and the likelihood of developing mild cognitive impairment (MCI) and Alzheimer's disease in a unique group(More)
CONTEXT Approximately 300 000 sport-related concussions occur annually in the United States, and the likelihood of serious sequelae may increase with repeated head injury. OBJECTIVE To estimate the incidence of concussion and time to recovery after concussion in collegiate football players. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of(More)
PURPOSE The purpose of our study was to investigate the association between prior head injury and the likelihood of being diagnosed with clinical depression among retired professional football players with prior head injury exposure. METHODS A general health questionnaire, including information about prior injuries, the SF-36 (Short Form 36), and other(More)
CONTEXT Lack of empirical data on recovery time following sport-related concussion hampers clinical decision making about return to play after injury. OBJECTIVE To prospectively measure immediate effects and natural recovery course relating to symptoms, cognitive functioning, and postural stability following sport-related concussion. DESIGN, SETTING,(More)
UNLABELLED PURPOSE OF THE STATEMENT: ▸ To provide an evidence-based, best practises summary to assist physicians with the evaluation and management of sports concussion. ▸ To establish the level of evidence, knowledge gaps and areas requiring additional research. IMPORTANCE OF AN AMSSM STATEMENT ▸ Sports medicine physicians are frequently involved in the(More)
OBJECTIVE To update the 1997 American Academy of Neurology (AAN) practice parameter regarding sports concussion, focusing on 4 questions: 1) What factors increase/decrease concussion risk? 2) What diagnostic tools identify those with concussion and those at increased risk for severe/prolonged early impairments, neurologic catastrophe, or chronic(More)
OBJECTIVE To determine the relationship between recorded head accelerations and impact locations and acute clinical outcome of symptomatology, neuropsychological, and postural stability tests after cerebral concussion in Division I collegiate football players. METHODS A prospective field study was used in which accelerometers were embedded in the football(More)
OBJECTIVE To determine if approximate entropy (ApEn), a regularity statistic from non-linear dynamics, could detect changes in postural control during quiet standing in athletes with normal postural stability after cerebral concussion. METHODS The study was a retrospective, case series analysis of centre of pressure (COP) data collected during the Sensory(More)
