Typical consult question “Please consult on this young male with history of persistent mood and behavior problems, since head injury 1 year ago.” Background Introduction Traumatic brain injury (TBI) is damage to the brain stemming from trauma to the head from a source outside of the brain. Even though the terms head injury and traumatic brain injury are often used interchangeably, it is important to remember that trauma to the head injury does not always result in brain injury. The severity of traumatic brain injury may range from mild to severe. TBI is a significant cause of disability and functional impairment worldwide. In this chapter, we will discuss features of depression from mild to severe, in the context of post-TBI depression. Epidemiology In the United States, there is an estimated incidence of more than 1.5 million cases of head injury annually, resulting in over a quarter of a million hospitalizations and more than 50,000 fatalities. More than 80,000 patients will experience chronic disability. The risk of fatal head injury is four times greater in men than in women. The incidence of head injury has a bimodal pattern, peaking from ages 15 to 25, with a second peak in advanced age. It is estimated that the healthcare cost for a patient with minor TBI over a one-year period is greater than $8,100 and in excess of $105,350 for those with severe head or spinal cord injuries.
