🎙️ Episode 17: “When Tantrums Go Too Far: Understanding Disruptive Mood Dysregulation Disorder (DMDD)”
Host: Matt Butterman
Guest: Dr. Gretchen Hoyle, MD, Pediatrician
Duration: ~35 minutes

Episode Summary:
Chronic irritability, frequent temper outbursts, and emotional volatility—these behaviors may go far beyond typical childhood tantrums. In this episode, host Matt Butterman is joined by pediatrician Dr. Gretchen Hoyle to unpack Disruptive Mood Dysregulation Disorder (DMDD), a relatively new but critical diagnosis that helps explain persistent mood and behavior challenges in some children and adolescents.

Dr. Hoyle explains what sets DMDD apart from ordinary moodiness and how it's different from disorders like bipolar disorder. She explores potential causes, including genetics, trauma, and neurodevelopmental factors, and discusses evidence-based treatment approaches ranging from cognitive behavioral therapy (CBT) and parent management training to medications such as atypical antipsychotics in severe cases. The episode also emphasizes the importance of early diagnosis, school accommodations (like 504 plans), and the effectiveness of collaborative care models in managing this complex disorder.

Key Topics Covered:

• What defines DMDD and how it differs from bipolar disorder

  
  

• Risk factors, including trauma, stress, and neurological dysregulation

  
  

• Why emotional regulation is at the core of DMDD

  
  

• Treatment strategies: CBT, parent training, medication, and trauma-informed care

  
  

• How schools and families can collaborate through 504 plans and support systems

  
  

• The role of pediatricians and behavioral health teams in identifying and managing DMDD

Three Takeaway Facts:

1. DMDD affects approximately 2–5% of children and adolescents, with symptoms typically appearing before age 10.

   
   

2. Unlike bipolar disorder, DMDD is chronic and non-episodic, characterized by persistent irritability and frequent behavioral outbursts.

   
   

3. With early intervention and a multi-pronged approach, many children with DMDD experience significant improvements over time.
