In this article we define the sequelea of acquired and traumatic brain injury in terms of impact on relationships, including family and social roles. The rehabilitation of children has implications for their role within the family and as pupil; and for adults, in their roles of parent and work colleague. We describe the ways in which relationships organise around the brain injury, via a system of
mutual influence and feedback loops, and how the relational network may buffer the stress and strain caused by injury and illness. Further discussion of the issues as applied to couple and family therapy, group therapy, vocational rehabilitation and wider support systems are presented. While there is no one overarching theoretical framework for conceptualising the issues, social-cognitive, systems and narrative perspectives make useful contributions.
