Approximately half of severely head-injured patients will need surgery to remove or repair hematomas (ruptured blood vessels) or contusions (bruised brain tissue). Disabilities resulting from a TBI depend upon the severity of the injury, the location of the injury, and the age and general health of the individual. Some common disabilities include problems with cognition […]

The severity of a TBI may range from “mild,” i.e., a brief change in mental status or consciousness, to “severe,” i.e., an extended period of unconsciousness or amnesia after the injury. TBI can cause a wide range of functional short- or long-term changes affecting thinking, sensation, language, or emotions. 1. Thinking (i.e., memory and reasoning); […]
