Acquired brain injury is a term that encompasses traumatic brain injury, anoxic brain injury, and cerebrovascular brain injuries such as aneurysm or subarachnoid hemorrhage. The different types of acquired brain injury, however, vary greatly in terms of prognosis.
Recent research has found that, of the different types of acquired brain injury, people with severe traumatic brain injuries are more likely to have faster recovery, gain more independence, and improve cognitive skills. People with severe traumatic brain injuries were also more likely to return home.
There are other distinctions between types of acquired brain injuries that could explain these differences in outcome. For instance, severe cerebrovascular brain injuries are more likely to occur in older adults. Severe anoxic brain injuries are more likely to have very low Glasgow Coma Scale scores upon admission. And, severe traumatic brain injuries tend to occur in younger males. These factors should all be considered when planning for discharge and recovery.
