This presentation explores the complex and often overlooked relationship between ADHD and Post-Traumatic Stress Disorder (PTSD). ADHD is substantially overrepresented in PTSD populations compared to the general adult population, with many studies showing approximately 20% of those with PTSD meet criteria for ADHD. People with ADHD have 2-3 times higher rates of PTSD than those without ADHD. ADHD and PTSD share overlapping features such as inattention, impulsivity, and emotional dysregulation—complicating assessment and treatment. The session will review current data on prevalence and co-occurrence, and highlight key distinctions to support accurate diagnosis. It will also examine ADHD-specific risk factors that may increase vulnerability to trauma exposure and the development of PTSD, including impulsivity, executive functioning challenges, and social difficulties. A central focus of the talk is clinical application: how ADHD impacts engagement in trauma-focused therapies, and how evidence-based PTSD treatments can be adapted to better meet the needs of individuals with ADHD. A specific focus will be on how individuals can rewrite a self-blame narrative when their trauma intersects with undiagnosed or poorly understood ADHD symptoms. This presentation provides a neurodevelopmentally informed framework for understanding trauma, with the goal of improving treatment outcomes and reducing misdiagnosis in this population.
