Sports-related concussions have unique features that distinguish them from those mild traumatic brain injuries (MTBI's) caused by other mechanisms. Sports-related MTBI's may result from relatively lower-velocity impacts as compared with high-speed motor vehicle collisions, and are thought to cause different neurophysiologic injury. A survey of youth coaches revealed 42% believed a concussion on...
Pediatric mild traumatic brain injuries, most of which are concussions, are an increasingly common reason for presentation to emergency departments. The diagnosis of concussion has increased dramatically over the past decade, necessitating the acute care provider to have up-to-date knowledge of the definition, pathophysiology, signs and symptoms, physical examination findings, and acute managem...
BACKGROUND AND PURPOSE Although concussion is common among athletes, evidence-based methods for clinical evaluation, treatment, and recovery are lacking. We used a prospective, functional neuroimaging approach to assess sports-related concussion in which imaging was performed before injury so that brain changes resulting from concussion could be better understood. METHODS Neurophysiologic cor...
Management of acute concussions is guided by consensus statement, and the return-to-play process begins when an athlete's symptoms and examination return to baseline. This process may be relatively clear if symptoms resolve within the normal time frame following a first or second concussion. This decision-making process is more complicated in an athlete with prolonged unresolved symptoms, multi...
OBJECT The aim of this study was to examine the brain's white matter microstructure by using MR diffusion tensor imaging (DTI) in ice hockey players with a history of clinically symptomatic concussion compared with players without a history of concussion. METHODS Sixteen players with a history of concussion (concussed group; mean age 21.7 ± 1.5 years; 6 female) and 18 players without a histor...
BRAIN CONNECTIVITY AFTER CONCUSSIONby
Mild traumatic brain injury (mTBI), or concussion, is the most common type of traumatic brain injury. With mTBI comes symptoms that include headaches, fatigue, depression, anxiety and irritability, as well as impaired cognitive function. Symptom resolution is thought to occur within 3 months post-injury, with the exception of a small percentage of individuals who are said to experience persiste...
UNLABELLED Dynamic postural control deficits and disrupted cortical pathways have been reported to persist beyond an athlete's return to activity after concussion, potentially increasing the risk of acute lower extremity musculoskeletal injury. PURPOSE This study aimed to investigate acute lower extremity musculoskeletal injury rates before and after concussion in athletes with concussion and...
Sports concussion is a major problem that affects thousands of people every year. Concussion-related neurometabolic changes are thought to underlie neurophysiological alterations and post-concussion symptoms, such as headaches sensitivity light noise, disabilities concentration tiredness. The injury triggers complex cascade involving multiple mechanisms. There pharmaceutical treatments target o...
Concussions carry devastating potential for cognitive, neurologic, and socio-emotional disease, but no objective test reliably identifies a concussion and its severity. A variety of neurological insults compromise sound processing, particularly in complex listening environments that place high demands on brain processing. The frequency-following response captures the high computational demands ...
