Acquired brain injury (ABI) severely affects both the injured patient and her/his family. This fact alone calls for a therapeutic approach addressing not only the individual victim of ABI but also her/his family. Additionally, the optimal outcome of posttraumatic cognitive rehabilitation may be best obtained by supplementing the institution-based cognitive training with home-based training. Moving cognitive training and other therapeutic interventions into the home environment does, however, constitute an additional challenge to the family structure and psychological wellbeing of all family members. We presently argue in favour of an increased utilization of family-based intervention programs for the families of brain injured patients – in general and especially in case of utilization of home-based rehabilitative training.
