Editorial: A Transdiagnostic Symptom Requires a Transdiagnostic Approach: Neural Mechanisms of Pediatric Irritability

Abstract

Irritability, a hallmark feature of the new DSM-5 category of disruptive mood dysregulation disorder (DMDD), is present in many pediatric disorders, including attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), depressive and anxiety disorders, and autism spectrum disorders. Indeed, irritability is among the most common presenting complaints in child psychiatry1 and predicts long-term impairments, including high suicidality and decreased education and income attainment.2
