Public health campaigns and efforts to raise awareness about the dangers of concussions and other related head injuries may have contributed to the 30 percent increase in emergency room (ER) visits for traumatic brain injury over a four-year period, according to a study published in the Journal of the American Medical Association. Researchers looked at emergency room visit data from the Nationwide Emergency Department Sample database. Between 2006 and 2010, 1.7 percent of the 138 million emergency department visits resulted in a diagnosis of traumatic brain injury. ER visits increased at a rate eight times higher than the total visits to emergency departments in that time period. "This study speaks to the increased recognition of traumatic brain injuries and concussion, increased education and awareness, and an increased number of people participating in sports," Dennis Cardone, M.D., co-director of the Concussion Center at NYU Langone Medical Center, told CBS News.
