dear board members suffering from pcs,
in my readings of concussion from scientific and non-scientific literature on the internet, it seems that pcs is a complex syndrome. rarely do NFL players come down with it. many NHL players come down with it after multiple concussions. pcs is mainly associated with cumulative impacts, motor vehicle accidents and assaults. the reason for this some believe is b/c of the rotational forces involved in vehicle accidents. in football and in direct trauma, the forces are mainly translational (linear forces). rotational forces are linked to the minute diffuse axonal injuries in concussions. translational forces are believed to rarely produce concussions, and if they do they're mild.

what i'm getting at is this. can those of us who have suffered mild traumatic brain injuries post our stats on how we got our concussions? also include whether consciousness was lost and amnesia experienced. was your injury direct trauma or indirect (eg. acceleration,deceleration). please include pcs symptoms, your age and sex and whether or not you have a history of head trauma. basically include everything you can about your head injury. maybe we'll find we have either one or more variables in common that caused this hellish nightmare called pcs. something that separates us from those who don't develop pcs. something that neuroscience should investigate.
thank you
