Abstract: Background:Traumatic brain injury results in some distinctive patterns of cognitive, behavioural and physical impairment which impact significantly on independent living skills and participation in work or study, social and leisure activities and interpersonal relationships. There is, however, still considerable variability in outcome across individuals in each of the reported domains. This has led to a significant body of research examining factors associated with outcome. A range of injury-related, personal and social factors have been shown to influence survival, as well as cognitive, functional and employment outcome. Methods:This paper reviews the factors associated with each of these aspects of outcome specifically injury-related factors, including neuroimaging findings, GCS and PTA, other injuries, and cognitive and behavioural impairments; demographic factors, including age, gender, genetic status, education, pre-injury IQ and employment status; and social factors including family and other social support, cultural factors, pre-injury psychiatric history and coping style. Conclusion:The paper identifies contributions and complex interrelationships of all of these factors to outcome following TBI. It concludes with a brief discussion of the implications of these factors for the rehabilitation process.
