Based on a systematic review by Soler-Gutiérrez, Pérez-González, and Mayas (2023), emerging research has revealed the crucial role of emotion dysregulation in adults with ADHD. This groundbreaking review illuminates emotion dysregulation as a transdiagnostic factor that fundamentally shapes our understanding, diagnosis, and treatment of ADHD.
Emotion Dysregulation in ADHD: A Transdiagnostic Factor
Emotion dysregulation refers to persistent difficulties in managing emotional responses, resulting in heightened reactivity, prolonged distress, and reliance on maladaptive strategies such as suppression or rumination.
Adults with ADHD are significantly more likely to experience:
• Lower scores on emotional regulation measures, often with medium-to-large effect sizes compared to non-ADHD controls.
• Impairments in daily life, including strained relationships, workplace challenges, and higher rates of substance use and criminal convictions.
As a transdiagnostic factor, emotion dysregulation is observed across multiple mental health disorders, including borderline personality disorder and depression. However, in ADHD, emotion dysregulation is uniquely tied to impulsivity and executive dysfunction, distinguishing it as a core symptom rather than a comorbid feature.
Recognizing Emotion Dysregulation in Clinical Practice
Clinicians can identify emotion dysregulation in adults with ADHD by assessing for:
• Emotional lability (frequent and intense mood changes).
• Persistent emotional distress and difficulty recovering from negative emotions.
• Over-reliance on maladaptive strategies like emotional suppression or self-blame.
Neurological Foundations of Emotion Dysregulation in ADHD
The neurological basis of emotion dysregulation in ADHD reveals impaired "top-down" regulation, where higher brain regions fail to modulate emotional reactivity effectively.
Dysfunction in the prefrontal cortex (executive control), anterior cingulate cortex (integration of emotion and cognition), and amygdala (emotional salience) disrupts emotion regulation.
The anterior cingulate cortex biases attention toward emotionally charged stimuli, reducing cognitive flexibility.
Deficient orbitofrontal cortex functioning limits the ability to integrate emotional information with personal goals.
Event-related potential (ERP) studies demonstrate heightened late positive potential (LPP) amplitudes in adults with ADHD, suggesting greater cognitive effort required to manage emotions.
Behavioral evidence shows that individuals with ADHD struggle to return to emotional baseline following negative experiences.
These findings suggest that emotion dysregulation stems from disrupted executive-emotional processing interactions, resulting in heightened emotional reactivity and ineffective regulation strategies.
Emotion Dysregulation as a Unique Target for ADHD Treatment
Addressing emotion dysregulation directly offers a unique avenue for improving outcomes in adults with ADHD. Treatments with empirical support include behavioral interventions, pharmacological approaches, and combined interventions,
Behavioral Interventions
Mindfulness-based therapies help individuals build emotional awareness and attentional control, which reduces the intensity and duration of emotional distress. Training in cognitive reappraisal strategies, such as reframing distressing situations, has shown promise for reducing emotional distress and improving self-regulation.
Pharmacological Approaches
Medications like methylphenidate and atomoxetine improve both core ADHD symptoms and emotion dysregulation, likely by enhancing prefrontal cortex functioning.
Combined Interventions
Integrating medication with behavioral strategies provides synergistic effects, addressing both emotional reactivity and executive deficits. Clinicians should include emotion-focused interventions in ADHD treatment plans, as these can improve emotional stability, attention, and overall quality of life.
Broader Research and Clinical Implications
This review underscores the need for:
• Standardized assessment tools: Tools like the Emotion Regulation Questionnaire or Difficulties in Emotion Regulation Scale should be used to evaluate emotion dysregulation in adults with ADHD.
• Focus on individual differences: Future research should explore how emotion dysregulation interacts with factors like gender, comorbidities, and medication use.
• Expanding interventions: Developing and testing targeted interventions, such as cognitive-behavioral or mindfulness-based therapies, will help refine treatment approaches for adults with ADHD.
Conclusion
Emotion dysregulation is increasingly recognized as a core symptom of ADHD in adults, with profound implications for diagnosis, treatment, and overall functioning. As a transdiagnostic factor, it links ADHD with other mental health disorders, but its unique manifestations—particularly its ties to impulsivity, executive dysfunction, and attentional biases—underscore its critical role in the ADHD symptomatology. Emotion dysregulation not only exacerbates functional impairments in relationships, work, and daily life but also provides a promising and underutilized target for intervention. This systematic review reveals important implications for improving ADHD treatment by highlighting emotion dysregulation as a core component rather than a secondary symptom. The findings support an integrated treatment approach that combines medication with behavioral interventions, as medications like methylphenidate and atomoxetine show effectiveness for both traditional ADHD symptoms and emotion regulation.
The research indicates that patients benefit most from developing adaptive emotion regulation strategies, particularly cognitive reappraisal and mindfulness techniques, while moving away from emotional suppression which delays recovery. Treatment should incorporate standardized assessment tools to monitor both ADHD symptoms and emotional functioning, with particular attention to gender differences, as women with ADHD often demonstrate greater emotion dysregulation.
The review emphasizes the importance of addressing comorbid conditions and executive function deficits, which are closely tied to emotion regulation challenges. Early intervention appears crucial, as emotional dysregulation manifests early in ADHD development. Parent training can be especially valuable given the intergenerational impact of ADHD symptoms on emotional development. By recognizing emotion dysregulation as a fundamental aspect of ADHD, clinicians can develop more comprehensive treatment approaches that address both traditional symptoms and emotional regulation skills, leading to better outcomes for individuals with ADHD.

Glossary
amygdala: a small almond-shaped region in the brain that plays a key role in processing emotions, particularly fear and pleasure, and is involved in emotional learning and memory formation.
anterior cingulate cortex: a region of the brain that wraps around the corpus callosum and is involved in integrating emotional and cognitive information, error detection, conflict monitoring, and decision-making.
cognitive reappraisal: a strategy for managing emotions by reframing a distressing situation to reduce its emotional impact. effect size: a statistical measure that quantifies the strength or magnitude of a relationship between variables or the size of a difference between groups. It helps us understand not just whether there is a difference, but how meaningful or substantial that difference is. event-related potentials (ERPs): brain responses measured through electroencephalography (EEG) that provide insights into emotional and cognitive processing. late positive potential (LPP): a neural marker of sustained attention to emotionally salient stimuli. motion dysregulation: difficulty managing emotional responses in a way that aligns with social or personal goals. Includes heightened reactivity, prolonged distress, and maladaptive strategies like suppression or rumination.
orbitofrontal cortex: the area of the prefrontal cortex located just above the eyes that is responsible for processing rewards, making decisions based on emotional information, and regulating social behavior.
prefrontal cortex: the front-most portion of the brain's frontal lobe that handles complex cognitive functions including planning, decision-making, impulse control, working memory, and emotional regulation.
transdiagnostic factor: a symptom or process that occurs across multiple mental health disorders, rather than being specific to one diagnosis.
