The American Medical Society for Sports Medicine (AMSSM) hosts its 27th Annual Meeting in Lake Buena Vista, Florida next month. As you will be aware, the AMSSM is one of our major Affiliate Societies, and we are pleased to bring you a wealth of research from Society Members and their colleagues in the form of the Abstracts of the Oral Research Poster Presentations, Rising with Research Presentations, Research Podium Presentations and Case Podium Presentations.
I always enjoy reading the AMSSM Abstracts as there is such a diverse and interesting range of research to be found within these and there is always a great opportunity to learn some pearls and to build on clinical experience by reading the Case Presentations.
Later on in our next issue, it will be the turn of our Founder Society, the Canadian Academy of Sport and Exercise Medicine (CASEM) to showcase the work of their Members with the publication of the CASEM Abstracts, and we look forward to reading these as well.
The research body of evidence related to the issue of Chronic Traumatic Encephalopathy and neuropathic changes associated with participation in contact sports continues to grow, and this month we present the findings of a study conducted by Professor Caleb Adler and colleagues from the University of Cincinnati College of Medicine in Ohio on a small cohort of former college football players, where MRI evidence of neuropathic changes were found several years after the end of their active careers in comparison to a control group of track and field athletes.
The former football players showed lower cortical thickness across the prefrontal and temporal brain regions on average compared with the control group, and there was evidence of a correlation between the number of reported concussions and the extent of the changes seen in these areas of the brain. This study, although small and not without its limitations, suggests that there may be adverse neurological consequences from playing high-level collegiate football which may persist into later life, and the authors call for larger, longer-term studies to better understand the neurological risks for college football players and the potential longer-term consequences for these young players.
Complimentary to this Original Research article, Vos and colleagues present a Systematic Review of the literature concerning the issue of the Consequences of Traumatic Brain Injury in Professional American Football Players. Amongst 21 included studies meeting inclusion criteria, the Authors found strong evidence for an association between a history of concussive episodes in American Football and depression in later life, and moderate evidence for an association between traumatic brain injury and mild cognitive impairment.
On the our main topic of concussion and traumatic brain injury in sport this Issue, we also bring you six other Original Research articles on related subjects including the influence of helmet faceguards on head impact location and severity, effects of ADHD and academic difficulties on baseline ImPACT testing, an Investigation of the Rosenbaum Concussion Knowledge and Attitudes Survey in Collegiate Athletes, the influence of genetics on baseline neurocognitive performance and concussion history amongst collegiate athletes, seasonal changes in cognitive functioning amongst high school football players, and the relationship of vision and vestibular dysfunction with prolonged concussion recovery amongst children, together with two Brief Reports on related topics.
CJSM will be present at the AMSSM Conference, and you can keep up to date with events on our social media channels on Twitter @CJSMonline , FaceBook https://www.facebook.com/pg/cjsportmed/about/ , and on our blog at https://cjsmblog.com
Enjoy the Issue, and have a great time at the AMSSM Conference if you're attending - I'm sure you will.
