Brain injury : [BI]
-
Survivors of traumatic brain injury (TBI) are at increased risk for development of severe, long-term psychiatric disorders. However, the aetiology of these disorders remains unclear. This article systematically reviews the most current prevalence rates and evidence for causality, in terms of established criteria. ⋯ Non-organic factors, including pre-morbid personality traits and post-injury psychological reactions to disability and trauma, are implicated in the generation and maintenance of post-TBI psychiatric disorder. There remains insufficient evidence to conclude what role the neuropathological consequences of TBI play in the development of post-TBI psychiatric disorder.
