The neurocognitive sequelae of a sport-related concussion and its management are poorly defined. Detecting deficits are vital in making a decision about the treatment plan as it can persist one year or more following a brain injury. The reliability of traditional cognitive assessment tools is debatable, and thus attention has turned to assessments based on electroencephalogram (EEG) to evaluate subtle post-concussive alterations. In this study, we calculated neurocognitive deficits combining EEG analysis with three standard post-concussive assessment tools...

Concussion is defined as a complex pathophysiological process affecting the brain that is induced by the application or transmission of traumatic biomechanical forces to the head. The result of the impact is the onset of transient symptoms that may be experienced for approximately 2weeks in most individuals. However, in some individuals, symptoms may not resolve and persist for a protracted period and a chronic injury ensues. Concussion symptoms are generally characterized by their emergence through changes in affect, cognition, or multi-sensory processes including the visual and vestibular systems...

The perception that children and adolescents have of injuries may be influenced by their depiction in sport-related films. The objective of this study was to determine the depiction of injuries in a select number of sport-related films. Forty-four films were analyzed. Injury category, on-the-field management, and long-term management were determined for each injury. Major injuries were defined as injuries requiring prompt intervention and immediate discontinuation of sport participation. A total of 49 injuries were depicted, categorized as fracture (n = 11), contusion (n = 10), brain concussion (n = 8), muscle cramps (n = 5), laceration/abrasion (n = 4), ligamentous knee injury (n = 4), shoulder dislocation (n = 2), rotator cuff injury (n = 2), ankle sprain (n = 2), and unspecified injury (n = 1)...

Most EEG studies used event-related potentials to assess long-term and cumulative effects of sport-related concussions on brain activity. Time-frequency methods provide another approach that allows the detection of subtle shifts in types and patterns of brain oscillations. We sought to discover whether event-related alpha activity would be significantly affected in asymptomatic multi-concussed athletes. We measured the amplitude of alpha activity (8-12Hz) from the EEG recorded during a visual-spatial attention task to compare event-related alpha perturbations in 13 multi-concussed athletes and 14 age-equivalent, non-concussed teammates...

In the United States alone, 1.6 to 3.8 million people have sports-related concussions yearly. The patho-mechanisms of concussions may not be directly measured by conventional neuroimaging; advanced models may be needed to address the shortcomings of the current clinical protocols. Multimodal advanced imaging may provide more accurate diagnosis and predict the clinical course of concussion, assessing the efficacy of existing and emerging multifaceted therapies. In this article, the authors present an overview and pictorial display of conventional and advanced multimodal MR imaging methods that have been applied to identify the brain structures affected in traumatic brain injuries...
