Cognitive and psychosocial outcome following moderate or severe traumatic brain injury.

The outcome of 96 consecutive adult patients with moderate to severe head injury was sequentially measured at 6, 12 and 24 months post-injury. In addition to global outcome using the Glasgow Outcome Scale (GOS) and a battery of neuropsychological tests of cognitive function, the Head Injury Symptom Checklist (HISC) and Relative's Questionnaire (RQ) were used. Although poorer GOS scores and severe cognitive impairments were typically associated with greater severity of initial injury, relatives reported similar functional problems irrespective of injury severity. This illustrates the legacy of moderate head injury in influencing many aspects of everyday life, supporting the argument that the needs of this group should not be overlooked.
