What Is Traumatic Brain Injury?
Traumatic Brain Injury (TBI) refers to insult to the brain that causes impairment. Common causes of TBI are the result of a blow to the head, stroke, brain tumor, infection, lack of oxygen (hypoxia), and/or toxic chemicals. TBI is a major cause of death and disability in the US and a significant public health concern as 1.7 million people sustain a TBI in a given year. Depending on the severity of the injury, symptoms may remit after a short period of time or may cause life-long disability. Injury to the brain impacts personality, cognition and behavior. Although the majority of TBIs are classified as concussions or mild TBIs, as many as 10% of those who have TBI experience complex symptoms that last from months to years.
