Overview
This lecture by Dr. Russell Barkley examines the central role of emotion in ADHD, providing evidence for its inclusion as a core symptom and discussing implications for diagnosis, comorbidity, and treatment.
Nature of Emotion and Emotional Self-Regulation
- Emotion is a short-term, situationally-provoked change in intention, behavior, arousal, and motivation.
- Moods are longer-lasting and less situation-specific than emotions.
- Emotional self-regulation has two stages: automatic emotional response and top-down executive control to moderate that emotion.
- Gross’s process model describes four stages of emotion: situation, attention, appraisal, and response.
ADHD Core Symptoms and Where Emotion Fits
- ADHD is defined by impairments in attention (persistence, working memory) and inhibition (impulsiveness, hyperactivity).
- Emotional impulsiveness and deficient self-regulation are overlooked but crucial features.
- Individuals with ADHD show impulsive, intense, and poorly regulated emotions, especially negative ones (frustration, anger, impatience).
Evidence for Emotion as a Central Feature in ADHD
- Historical accounts (since 1798) consistently included emotion dysregulation in ADHD descriptions.
- Neuroanatomical studies show underdevelopment in brain regions (right orbital prefrontal cortex, basal ganglia, cerebellum, anterior cingulate, corpus callosum) critical for emotional control.
- Theoretical models and rating scales confirm that emotional regulation is impaired in ADHD, alongside inattention and inhibition.
Emotional Dysregulation, Comorbidity, and Life Impairments
- Emotional dysregulation in ADHD contributes to Oppositional Defiant Disorder (ODD), with OD reflecting both biological (emotion) and learned (social conflict) components.
- Emotional symptoms in ADHD predict social rejection, interpersonal hostility, job loss, relationship conflict, financial mismanagement, aggressive driving, and transmission to offspring.
- Emotional dysregulation impairs major life activities beyond what is predicted by traditional ADHD symptoms.
Diagnostic and Treatment Implications
- Emotional symptoms in ADHD are rational, situation-specific, and should not be mistaken for mood disorders, which are excessive, irrational, and pervasive.
- ADHD medications (e.g., stimulants, atomoxetine, guanfacine) improve emotional regulation via different neural pathways.
- Non-medication interventions: teach emotion management strategies, replenish self-regulation resources (breaks, positive self-talk, exercise, glucose intake).
- ADHD treatments improve emotional symptoms and related life impairments but may require additional interventions for comorbid disorders and family/social factors.
Key Terms & Definitions
- Emotion — A short-term, situation-specific change in behavior, arousal, and motivation.
- Emotional Self-Regulation — Executive control processes to moderate or adapt emotional responses.
- Emotional Impulsiveness (EI) — Rapid, unfiltered display of emotion.
- Deficient Emotional Self-Regulation (DESR) — Difficulty managing or moderating emotions.
- Gross’s Process Model — A four-stage framework for emotional processing.
- Oppositional Defiant Disorder (ODD) — Childhood disorder with emotional dysregulation and social conflict dimensions.
Action Items / Next Steps
- Review Gross’s process model of emotion.
- Practice and implement CBT strategies for emotional regulation.
- For clinicians: evaluate for emotional symptoms in ADHD assessments and consider family/parental ADHD.
