Self-awareness deficits are common after acquired and (traumatic) brain injury (ABI), particularly in social behaviour, yet the underlying cognitive and neuroanatomical structures supporting social self-awareness are not fully understood. This paper reviews the current literature on prevalence, type and severity of self-awareness deficits in ABI. Neuropsychological and neuroanatomical models are reviewed and theoretical frameworks are examined. We summarise results of a case-control comparison of 20 ABI patients with and 20 ABI patients without behavioural disturbance. Our research found that lack of social self-awareness predicts behavioural disturbance in acquired and traumatic brain injury independent of cognitive and executive function. Theory of mind ability was related to self-awareness and a possible role for metacognition and affective processes in self-awareness is discussed to account for social self-awareness deficits.
