BACKGROUND Little is known about the short-term and long-term sequelae of concussion, and about when athletes who have sustained such injuries can safely return to play. PURPOSE To examine whether sports-related concussion increases the risk of subsequent injury in elite male football players. STUDY DESIGN Prospective cohort study. METHODS Injuries were registered for 46 male elite footba...

Sports-related concussion has emerged as a public health crisis due to increased diagnosis of the condition and increased participation in organized and recreational athletics worldwide. Under-recognition of concussions can lead to premature clearance for athletic participation, leaving athletes vulnerable to repeat injury and subsequent short- and long-term complications. There is overwhelming...

We review the current topic in sports-related head injuries including acute subdural hematoma (ASDH), concussion, and chronic traumatic encephalopathy (CTE). Sports-related ASDH is a leading cause of death and severe morbidity in popular contact sports like American football in the USA and judo in Japan. It is thought that rotational acceleration is most likely to produce not only cerebral conc...

Sport-related mild traumatic brain injury (mTBI) or concussion is a significant health concern to athletes with potential long-term consequences. The diagnosis of sport concussion and return to sport decision making is one of the greatest challenges facing health care clinicians working in sports. Blood biomarkers have recently demonstrated their potential in assisting the detection of brain in...

OBJECTIVE To determine the risk of concussion among youth football players (ages 8-12 years). STUDY DESIGN Participants included 468 male youth football players in western Pennsylvania during the 2011 youth football season. Incidence rates (IRs) and incidence density ratios (IDRs) of concussion were calculated for games and practices and for age groups. RESULTS There was a total of 11,338 (...

The King-Devick test (K-D) was introduced in 2011 as a quick, easy and cost-effective way to screen for a concussion. Relying on differences in visual scanning between a baseline and post-injury examination to discern a concussion, the test has been found to be sensitive to concussions immediately (within minutes) following injury. The aim of this paper was to determine whether the K-D is sensi...

BACKGROUND Ice hockey and football players suffering concussions might have an increased risk for injuries afterwards. We aimed to investigate if concussions predisposed athletes for subsequent sport injuries. METHODS Patient data were obtained from a data base established at the University Hospital in Umea, Sweden. Athletes who had suffered a concussion were included if they had been aged be...

This article reviews the essential components of a practical, evidenced-based approach to the management of sport-related concussion in an ambulatory care setting. The model presented is based on the core philosophy that concussion assessment and management be approached from the biopsychosocial perspective, which recognizes the medical/physiological, psychological, and sociological factors tha...

Concussion is a form of traumatic brain injury (TBI) that presents with a wide spectrum of subjective symptoms and few objective clinical findings. Emerging research suggests that one of the processes that may contribute to concussion pathophysiology is dysregulation of cerebral blood flow (CBF) leading to a mismatch between CBF delivery and the metabolic needs of the injured brain. Cerebrovasc...

CONTEXT Increasing attention is being paid to the deleterious effects of sport-related concussion on cognitive and brain health. OBJECTIVE To evaluate the influence of concussion incurred during early life on the cognitive control and neuroelectric function of young adults. DESIGN Cross-sectional study. SETTING Research laboratory. PATIENTS OR OTHER PARTICIPANTS Forty young adults were ...
