Traumatic brain injury is pervasive in both civilian and military populations. In fact, TBI in the civilian population is eight times as frequent as breast cancer, AIDS, spinal-cord injury, and multiple sclerosis combined. According to the Center for Deployment Psychology, an estimated 10–20% of all service members who served in operations Iraqi Freedom and Enduring Freedom sustained a TBI, with most being concussions, or mild TBIs — mild TBIs are also sometimes called concussions. As such, TBI is a “hot topic” in the military community. However, TBI and its causes, symptoms, and treatment are often misunderstood, and this misunderstanding can lead to a mistreatment of the individuals with TBI and a mishandling of the issues surrounding TBI. Several myths about TBI appear to contribute to this misunderstanding. Below, several such myths are addressed.
