Summary Emotion processing abnormalities and sleep pathology are central to the phenomenology of paediatric posttraumatic stress disorder, disturbance has been linked development, maintenance severity disorder. Given emerging evidence indicating a role for in emotional brain function, it proposed that dysfunctional experiences during may play significant affective disorders, including Here we sought examine relationship between emotion typically developing youth, youth with diagnosis disorder . We use high‐density electroencephalogram compare baseline following performance on task designed assess both memory reactivity negative neutral imagery 10 youths age‐ sex‐matched non‐traumatized youths. Subjective ratings arousal (ΔArousal = post‐sleep minus pre‐sleep ratings) remain unchanged (mean increase 0.15, CI −0.28 +0.58), but decreased TD decrease −1.0, 95% −1.44 −0.58). ΔArousal, or habituation, was negatively correlated global change slow‐wave activity power ( ρ −0.58, p .008). When considered topographically, correlation Δslow‐wave habituation most frontal cluster 27 electrodes (Spearman, −0.51, .021). Our results highlight importance adaptive have implications symptom persistence Impairments represent modifiable risk factor
