High incidence of concussion, but low knowledge levels among young adults

Cerebral concussion is a brain injury, that involves a complex pathophysiological process that affects the brain as a result of biomechanical forces. With the increasing prevalence, it is important that the public is knowledgeable about concussion and its symptoms, so that they can bring attention to individuals with concussion symptoms soon after onset, for appropriate care. The aim of this study was to determine the knowledgeability of young adults. Secondary aims were to compare the knowledgeability of young adults of different age, of different countries of residence, of different sex, and of different perceived knowledge about concussions. An online survey was circulated to young adults in Canada, the US and the UK. The survey consisted of three components - a consent form, respondent demographics and eight questions to assess each respondent's knowledgeability of concussions. The knowledgeability of each respondent was determined by the summation of the number of correct responses to the knowledge questions. A total of 307 respondents consented and completed the survey in its entirety. The mean knowledge score was 4.25 out of 8. None of the cohort analyses based on demographics - 19 years old and under vs. 20 years and older; North Americans vs. non-North Americans; females vs. males - suggested that one group was more knowledgeable than the other group. These results suggest that educational programs can be developed to increase awareness of concussions. As each cohort seems to have similar starting knowledge levels, it seems appropriate to develop a uniform program to first try to increase knowledgeability, and then produce specialised programs to raise knowledge of certain cohorts. However, prior to the establishment of programs, further studies should be conducted to verify the results disclosed herein.
