Concussion is a worldwide issue in sports medicine at present, and in recent years has evolved into a major consideration for sports in the United Kingdom (UK). Governing bodies, sports clinicians, and indeed athletes themselves are dealing with the implications that this injury brings. In parallel with this, innovative means of managing this condition are emerging. The creation of specialized concussion clinics (which mirror those present in the United States and Canada) is one means of enhancing concussion care in the UK...

Motor and cognitive dysfunction is intractable sequela in the acute stage of concussion. While typical concussion recovery occurs in two weeks, empirical evidence suggests that some sequela persist beyond this period, though there is inconsistency surrounding the duration the sequela persist. In part, confusion around the issue is limited by the volume of literature evaluating those with a concussion history, permitting vast interpretations of significance. The purpose of this paper is to review the concussion history literature, summarizing the long-term effects of concussion history on motor and cognitive performance...

Importance: Scientific and lay interest in negative outcomes associated with exposure to repetitive brain trauma (RBT) continues to strengthen. Concerns about the association between RBT and dementia began more than a century ago, but have resurfaced in the last decade with the more recently described chronic traumatic encephalopathy (CTE). Chronic traumatic encephalopathy is a tauopathy associated with RBT that has become inextricably linked to conversations about sport-related concussion and mild traumatic brain injury...

Arterial spin labeling (ASL) has emerged as a technique for assessing mild traumatic brain injury (mTBI), as it can non-invasively evaluate cerebrovascular physiology. To date, there is substantial variability in methodology and findings of ASL studies of mTBI. While both increased and decreased perfusion are reported after mTBI, more consistency is emerging when perfusion is examined with regard to symptomology. We evaluated 15 teenage athletes 2 and 6 weeks after sports-related concussion (SRC group) using pseudo-continuous ASL...

The recent passage of state youth sports concussion laws across the country introduces clinical implications for health care professionals caring for student-athletes. Although the laws were established to provide protections for student-athletes and prevent adverse outcomes, efforts aimed at implementation have uncovered various challenges in concussion diagnosis and management. Some of the most salient issues include medical evaluation, return to play, and return to learn. For this reason, health care professionals play a pivotal role in determining the critical next steps after a student is removed from play with a suspected concussion...
