A PROSPECTIVE STUDY OF SEVERE IRRITABILITY IN YOUTHS: 2- AND 4-YEAR FOLLOW-UP

Abstract

By the 4-year follow-up, only 40% of youths meet strict SMD criteria; however, most continue to display clinically impairing symptoms and significant impairment warranting psychiatric treatment. These findings provide evidence for the course of irritability, with implications for DMDD. Future research with populations meeting DMDD criteria and followed through the ages of high risk for psychiatric diagnoses is necessary.
