Summary

In order to estimate the impact of concussive brain injuries on global health and well-being, one needs to know both the frequency with which they occur and the frequency with which they are associated with impairment, of what degree, for what time period. Moreover, accurate appraisals of variations in occurrence, severity, and duration of impact between demographically or biologically different cohorts (e.g., the special vulnerability of teenaged girls) is necessary both to discover risk factors and, eventually, to inform the innovation of targeted preventions and interventions. None of those numbers is known. Occurrence is unknown because only a subset of concussive brain injuries ever presents for medical attention. However, based on evidence regarding non-reporting and non-recording, it seems likely that frequently cited published estimates of occurrence are underestimates. More important: dated methods such as conventional neuropsychological testing were once cited as evidence that the effects of sports-related concussions are transient and benign. As illustrated by the cover of this textbook, modern science dispels that mythology.
