Sports-related concussion has become an increasingly prevalent clinical problem over the past few years. It has finally been recognized as a legitimate and serious medical condition that requires appropriate and full medical attention. The injury of a number of recent high profile professional athletes whom have suffered concussions has heightened awareness among both health care professionals and the public alike and has made it one of the most important clinical issues in sports medicine. Although increasingly common, concussions, by nature, are elusive and difficult to detect. Unfortunately, there is no current single litmus test that accurately and reliably detects the presence of a concussion. More often than not, concussed patients can have normal neurological examinations and negative neuroimaging results, yet may have the lingering aftereffects of the injury.
