ADHD and DMDD Comorbidities, Similarities and Distinctions

Laura Masi and Martin Gignac

Since the mid-90s, the number of children treated for bipolar disorder has increased considerably. Although the need to avoid a confusing terminology regarding bipolar disorder was generally accepted, agreement on diagnosis for this population was difficult to conclude. In particular, the controversy concerned children with chronic irritability and high comorbidity with ADHD. The DSM-5 working group on mood disorders proposed a new diagnosis: Dysruptive Mood Dysregulation Disorder (DMDD). If the distinction with bipolar appears now clear, high comorbidity with ADHD is concerning and makes the nosological limits unclear. However, differences are present and these two diseases must be distinguished in order to recognize their particular problems. Investigation of overlaps between ADHD and DMDD should help clarify their etiology, course and outcome.
