Brain -- Concussion -- Complications, Brain damage




Concussions, or mild traumatic brain injuries, do not have a universally accepted definition but there are key features that the experts agree upon; most notably that they are caused by a direct blow, they cause functional disturbances, and that they cannot be explained by another injury or impairment. Most concussions are resolved within a few days but 10-20% have lingering effects that can last for years. In this study, frequency of lingering injury to each brain region was determined from data from thirteen studies and compared to Scheid et. al's frequency of short term injury by brain region using ANOVA testing. No significance was found in the difference in frequency of injury by region between long term and short term concussions (p-value=0.717, n=10, ⍺=0.05). This suggests that regions either heal at the same rate or can all be compensated for. Further research is needed to determine the pathophysiological root of the long-term effects of concussions.
