Influence of National Traumatic Events on Inattention and Hyperactivity/Impulsivity Symptoms in Young Adults With and Without ADHD

These results suggest that national traumatic events can temporarily increase inattention and hyperactivity/impulsivity symptoms among young adults without an ADHD diagnosis, even if they were not directly exposed to the events. This increase tends to return to baseline over time. Conversely, individuals diagnosed with ADHD did not experience a worsening of symptoms and instead showed a slight reduction in severity, particularly in inattention, following the traumatic event. Future research should further explore the functional capabilities of individuals with ADHD under acute stress to deepen the understanding of this relationship.
