The National Institutes of Health formally acknowledges that CTE is caused in part by repeated TBI
The National Institutes of Health (NIH) recently acknowledged that there is a causal link between repeated blows to the head and chronic traumatic encephalopathy (CTE).
Concussion expert Dr. Paul McCrory’s pattern of publication misconduct
The British Journal of Sports Medicine (BJSM) recently retracted nine more articles published by renowned concussion expert Dr. Paul McCrory. The nine retractions include five cases of plagiarism, three cases of redundant publication, and one case of misquotation.
Researchers find vestibular dysfunction stems from injury to the peripheral vestibular system
In a study published in the Journal of Neurotrauma, researchers aimed to “establish whether vestibular dysfunction … is of central, peripheral, or combined origin.” They found that vestibular dysfunction is associated with peripheral vestibular system injury.
Duration of continued athletic participation after sport-related concussion impacts recovery outcomes
A study evaluated the duration of continued participation after a suspected sport-related concussion (SRC) and its impact on recovery outcomes in collegiate athletes. The researchers found that continued participation (within a range of 0-90 minutes) after SRC was associated with worse outcomes.
Baseline evaluations for diagnosing concussion do not improve diagnostic accuracy
A study by Dr. Lyndsey M. Ferris et al., published in the American Journal of Sports Medicine, analyzed the utility of baseline evaluations for identifying acute concussions in college athletes. The researchers found that using baseline evaluations does not significantly improve diagnostic accuracy.
Predicting prolonged concussion recovery with a decision tree model
A study by Dr. Michael Robinson et al., published in American Journal of Physical Medicine & Rehabilitation, used a decision tree to identify patients at higher risk of developing prolonged concussion symptoms. The researchers found that feelings of fogginess and sadness at initial assessment were predictive of prolonged symptoms “lasting 28 days or more postconcussion.”
Concussion education program for high school athletes is achieving success
A web-based concussion education initiative sponsored by the Barrow Neurological Institute, Barrow Brainbook, has reached over one million high school athletes in Arizona since its establishment in 2011. The initiative teaches students how to prevent concussions, recognize the signs and symptoms of concussions, and respond to concussions.
Accurate score conversions for two different concussion assessments
A study found that the Sport Concussion Assessment Tool (SCAT) symptom scores can be converted to Rivermead Post-concussion Symptoms Questionnaire (RPQ) scores. “Being able to convert between the two scores would facilitate comparison of results in the concussion literature.”
