Factors affecting the concussion knowledge of athletes, parents, coaches, and medical professionals

            The authors wanted to know the predictors of concussion knowledge in people. The researchers found people in canada to answer these questions. The people could identify 80.6% of the symptoms of a concussion. With most of the known ones being the cognitive symptoms. The researchers also found that if you were exposed to brain trauma or people who experienced brain trauma you could better identify symptoms. The researchers concluded that concussion management and prevention should be aimed at those identified in the study to be less likely to know the symptoms of a concussion.

Impact of exercise on clinical symptom report and neurocognition following concussion in children and adolescents

This study took 30 kids recruited from an emergency department. At day 2 and 10 post self-reported symptom resolution they completed a strenuous exercise program and the researchers measured their neurocognitive performance. The researchers found the expected recovery pattern for symptom resolution and neurocognition performance was dependent on the degree of cognitive demand. Furthermore, the researchers found that there was a decrease in performance on day 10 compared to day 2. The researchers concluded that premature return to normal activities may slow recovery.

Long-term Effects of Adolescent Sport Concussion Across the Age Spectrum

            The researchers wanted to see the long-term effects of concussion sustained in high school and how it impacted their life after high school. The researchers got 83 people some with and some without concussions and gave them neurocognitive testing. the researchers found that age did impact performance on these neurocognitive tests. However, the researchers didn’t find any link with concussion history.

The first week after concussion: Blood flow, brain function and white matter microstructure

The researchers scanned 52 athletes in a MRI, Half of whom had a concussion. The researchers looked at cerebral blood flow, global functional connectivity of grey matter, fractional anisotropy, and mean diffusivity of white matter. The researchers found some novel effects with all of these measures, however, they were all time dependent from the time of acute concussion to the time of scanning. These findings, the authors noted, highlight the importance of the time interval which will have significant impacts on acute MRI data and concussion outcomes.

The King–Devick (K–D) test and concussion diagnosis in semi-professional rugby union players

The researchers wanted to find out how useful the king-devick (K-D) test is. The researchers then took a big pool of 176 male players and got pre-season baselines and post-match K-D scores for those suspected of having a concussion. The researchers used 19 concussions in 18 players and 33 controls obtained during the season for analysis. The researchers found the K-D test identified 53% of concussions. The researchers concluded that the K-D test isn’t effective as a standalone tool, but when they combined it with the Pitch Side Concussion Assessment version 2 the percentage of concussions identified went up to 89%, thus making the K-D test a good complimentary tool.
