Symptomatic Associations between Attention- Deficit/Hyperactivity Disorder, Trauma, and Posttraumatic Stress Disorder in Children
Sammanfattning: This study aimed to assess the symptomatic associations betweenattention-deficit/hyperactivity disorder (ADHD) symptomatology, traumaexposure, and posttraumatic stress disorder (PTSD) symptomatology. Thesample consisted of 16,340 children from a population-based Swedish twinstudy. Trauma exposure, PTSD, and ADHD symptomatology was parentratedin a structured telephone interview. Trauma exposure and subsequentPTSD was positively associated with ADHD prevalence. ADHD in traumaexposedindividuals was more severe than in non-trauma-exposedindividuals. Individuals with PTSD and ADHD displayed an elevatedADHD symptomatology compared to trauma-exposed individuals withoutPTSD. In comorbid ADHD and PTSD, the order of trauma and onset ofADHD did not impact ADHD severity. The study confirms the associationbetween ADHD, trauma exposure, and PTSD and suggests that traumaexposedchildren are at risk for more severe ADHD.
