Animal models are often presumably the first step in determining mechanisms underlying disease, and the approach and effectiveness of therapeutic interventions. Perinatal brain damage, however, evolves over months of gestation, during the rapid maturation of the fetal and newborn brain. Despite marked advances in our understanding of these processes and technologic advances providing an improved window on the timing and duration of injury, neonatal brain injury remains a moving target regarding our ability to mimic its processes in an animal model. Moreover, interfering with normal processes of development as part of a therapeutic intervention may do more harm than good. Hence, controversy continues over which animal model can reflect human disease states. Numerous models have provided information regarding the pathophysiology of brain damage in term and preterm infants. Our challenges consist of identifying infants at greatest risk for permanent injury, identifying the timing of injury, and adapting therapies that provide more benefit than harm. A combination of appropriately suitable animal models to conduct these studies will bring us closer to understanding human perinatal damage and the means to treat it. (C) 2009 by Elsevier Inc.
