Emotion dysregulation in attention deficit hyperactivity disorder.

Area of Science:

• Neuroscience
• Psychiatry
• Developmental Psychology

Background:

• Emotion dysregulation is a common comorbidity in Attention Deficit Hyperactivity Disorder (ADHD).
• The conceptualization and clinical management of co-occurring ADHD and emotion dysregulation remain challenging.
• Existing ADHD treatments may indirectly improve emotion regulation, but targeted approaches are needed.

Purpose of the Study:

• To review and synthesize current literature on the relationship between ADHD and emotion dysregulation.
• To explore potential neurobiological mechanisms underlying emotion dysregulation in ADHD.
• To examine different theoretical models explaining the ADHD-emotion dysregulation overlap and guide future research.

Main Methods:

• Systematic review of existing quantitative and qualitative research.
• Analysis of findings related to prevalence, lifespan impact, and clinical impairment.
• Examination of neurobiological correlates and proposed theoretical models.

Main Results:

• Emotion dysregulation is prevalent across the lifespan in ADHD, significantly contributing to impairment.
• Deficits in attentional processes (orienting, recognition, allocation) towards emotional stimuli are implicated.
• Dysfunction in the striato-amygdalo-medial prefrontal cortical network is associated with emotion dysregulation in ADHD.
• Current ADHD treatments show some efficacy for emotion dysregulation, but novel therapeutic strategies focusing on this comorbidity are warranted.

Conclusions:

• Emotion dysregulation is a significant and pervasive issue in ADHD, impacting functioning throughout life.
• Understanding the attentional and neurobiological underpinnings is crucial for developing effective interventions.
• Further research is needed to differentiate between ADHD with emotion dysregulation as distinct dimensions, a core feature, or a unique nosological entity.
