Two Clinical Vignettes on Disruptive Mood Dysregulation Disorder: Diagnostic Ambiguity and Unclear Course

Disruptive mood dysregulation disorder (DMDD) is a DSM-5 diagnosis for children and adolescents characterized by persistent irritability and severe temper outbursts.Due to overlapping symptoms with other disorders, DMDD is frequently misdiagnosed.This study presents two clinical cases.The first case involves a 14-year-old male patient with chronic irritability, temper outbursts, and impulsive aggression, resulting in significant academic and social impairment.The second case involves a 14-year-old female patient who initially presented with pathological gambling and emotional instability.These cases illustrate the diagnostic complexity of DMDD and its potential progression to mood disorders, such as bipolar disorder.Careful clinical observation and comprehensive assessment of irritability and mood dysregulation are essential for an accurate diagnosis.This study underscores the importance of continuous follow-up in DMDD patients to monitor disease progression and optimize treatment strategies.Understanding the developmental trajectory, comorbidities, and treatment responses in DMDD can help improve clinical outcomes and prevent long-term psychiatric complications.
