“…Post-traumatic pain correlates with presence of PPCS (Sheedy et al, 2006); and pain has its own set of correlates, by itself, potentially affecting cognitive performance and emotional status (Alfano, 2006;Karp et al, 2006). None of this even addresses the complexity of WAD, as already mentioned, and WAD pain-related problems (Holm et al, 2006;Johansson, 2006;Zumsteg et al, 2006), nor post-traumatic headaches (Lew et al, 2006;Weiss et al, 1991) which are commonplace in concussion, especially those caused by MVAs. Not only is the brain concussed, but also other organs such as the eye, inner ear, and soft internal organs (Frater & Haindl, 2003;Keane & Baloh, 1992;Nolle et al, 2004); and injury to these organs can be a source of symptoms.…”
