This report begins by providing two case examples of closed head injuries in families. Closed head injuries or traumatic brain injuries are briefly defined and it is noted that brain injury can cause socialization problems, personality changes, and confusion. It is suggested that families that have an individual member with a closed head injury can become stuck in the developmental life cycle. The need for family education, support, and therapy is explained and strategies for helping families are discussed. It is recommended that family therapists working with these families: (1) understand the family history; (2) provide education, support, and therapy; and (3) encourage a supportive, nurturing environment. The need for a complete assessment is emphasized and the usefulness of an interdisciplinary team approach to assessment is discussed. Developmental issues are considered for children, adolescents, and adults who experience a closed head injury. (NB)
