Chronic pain in youth is common, with prevalence rates in some reports exceeding 50%. Given the plasticity of brain systems in youth and their general level of activity, the underlying processes relating to the evolution of chronic pain may be different from that observed in adults. One aspect that affects brain development is childhood stress. Preliminary research indicates that maladaptive responses to stressful events that induce biological and psychological inability to adapt may be related to pain chronicity in youth. This relationship is particularly notable given the high rates of exposure to stressful events in pediatric pain populations. A review of the literature was performed in the areas of biological, cognitive, psychological and social processes associated with chronic pain and psychological stress and trauma in youth and adult populations. The current review presents a theoretical framework, adapted from McEwen’s model (1998) on stress and allostatic load, which aims to outline the potential connection between exposure to stressful events and pediatric chronic pain. Avenues for future investigation are also identified.
