Recent developments in neuroscience provide important information for therapists working with maltreated children. Severe maltreatment and lack of significant attachment figures in the crucial early years lead to adverse brain development (De Bellis, 2001). It appears evident that traumatic memories are stored in the right hemisphere, making verbal declarative memory of the trauma more difficult (Schiffer, Teicher, & Papanicolaou, 1995). This research lays the groundwork for understanding why nonverbal, expressive therapies can be more effective than verbal therapies in work with severely maltreated children exhibiting attachment difficulties. This article explores current research in neuroscience and provides a rationale for expressive therapy as a treatment intervention for this population.
