Emotion dysregulation in adult ADHD: Introducing the Comprehensive Emotion Regulation Inventory (CERI)

Inflammation and emotion regulation: a narrative review of evidence and mechanisms in emotion dysregulation disorders

Emotion dysregulation (ED) describes a difficulty with the modulation of which emotions are felt, as well as when and how these emotions are experienced or expressed. It is a focal overarching symptom in many severe and prevalent neuropsychiatric diseases, including bipolar disorders (BD), attention deficit/hyperactivity disorder (ADHD), and borderline personality disorder (BPD). In all these disorders, ED can manifest through symptoms of depression, anxiety, or affective lability. Considering the many symptomatic similarities between BD, ADHD, and BPD, a transdiagnostic approach is a promising lens of investigation. Mounting evidence supports the role of peripheral inflammatory markers and stress in the multifactorial aetiology and physiopathology of BD, ADHD, and BPD. Of note, neural circuits that regulate emotions appear particularly vulnerable to inflammatory insults and peripheral inflammation, which can impact the neuroimmune milieu of the central nervous system. Thus far, few studies have examined the link between ED and inflammation in BD, ADHD, and BPD. To our knowledge, no specific work has provided a critical comparison of the results from these disorders. To fill this gap in the literature, we review the known associations and mechanisms linking ED and inflammation in general, and clinically, in BD, ADHD, and BD. Our narrative review begins with an examination of the routes linking ED and inflammation, followed by a discussion of disorder-specific results accounting for methodological limitations and relevant confounding factors. Finally, we critically discuss both correspondences and discrepancies in the results and comment on potential vulnerability markers and promising therapeutic interventions.

A Scoping Review of Factors Associated With Emotional Dysregulation in Adults With ADHD

OBJECTIVE

Emotion dysregulation is frequently seen in adults with ADHD and is associated with many adverse outcomes. We conducted a scoping review of factors associated with emotion dysregulation in adults with ADHD.

METHOD

PubMed and PsycInfo (EBSCO) were searched. Articles were included if they measured ADHD, emotional dysregulation or some aspect of emotional dysregulation, and at least one other construct. Studies examining physiological underpinnings as well as clinical trials examining the effect of ADHD medications on emotional dysregulation were excluded because recent reviews have already examined these topics.

RESULTS

Thirty-five studies were included in the review. Factors such as biological sex, comorbidities, attachment style, using certain emotional regulation strategies, and ADHD subtype tend to be related to emotion dysregulation.

CONCLUSION

Clinicians working with adults with ADHD can collect information on these factors to better understand risk for emotion dysregulation, and emotion regulation skills may be one area for intervention.

Evidence of emotion dysregulation as a core symptom of adult ADHD: A systematic review

Attention Deficit Hyperactivity Disorder (ADHD) is a developmental disorder, with an onset in childhood, that accompanies the person throughout their life, with prevalence between 3 and 5% in adults. Recent studies point towards a fourth core symptom of the disorder related to the emotional information processing that would explain the repercussions that ADHD has on the social, academic, and professional life of the people affected. This review aims to describe emotion dysregulation features as well as the brain activity associated in adults with ADHD. A search of the scientific literature was launched in specialized databases: PsycInfo, Medline, Eric, PsycArticle, Psicodoc and Scopus, following PRISMA guidelines. Twenty-two articles met the inclusion criteria: (a) an ADHD clinical diagnosis, (b) participants over 18 years old, (c) emotion regulation measurement, (d) empirical studies, and (c) in English. Due to the heterogeneity of the studies included, they were classified into three sections: measures and features of emotion regulation (ER) in people with ADHD, neurological and psychophysiological activity related to ER, and treatments. The studies found that meet the selection criteria are scarce and very heterogeneous both in aims and in sample features. Adults with ADHD show a more frequent use of non-adaptive emotion regulation strategies compared to people without ADHD symptoms. Moreover, emotion dysregulation was associated with symptom severity, executive functioning, psychiatric comorbidities, and even with criminal conviction. Different patterns of brain activity were observed when people with and without ADHD were compared. These results may suggest that psychopharmacological treatments as well as behavioral therapies could be useful tools for improving emotional difficulties in adult ADHD.

Group-based emotion regulation skills training for adults with ADHD: A feasibility study in an outpatient psychiatric setting

The aim of this open non-controlled clinical trial was to investigate the feasibility and preliminary treatment effects of a new group-based skills training program for adult ADHD: Group Therapy for Improving Emotional Acceptance and Regulatory Skills in Adults with ADHD (GEARS). Out of the 226 allocated patients, 213 initiated the treatment and 170 (80%) were considered treatment completers (i.e., attending at least 9 out of 14 sessions). A total of 158 of the completers also completed pre- and post-treatment assessments, and 126 provided assessments at the 3-month follow-up. Treatment credibility received high ratings, as did treatment satisfaction. Preliminary treatment effects showed significant improvements in emotion regulation with large effect sizes. Significant effects were also found for all secondary outcome variables: ADHD symptom levels, depression, anxiety, and quality of life. All significant effects remained at the 3-month follow-up. In conclusion, GEARS should be considered a feasible treatment in an outpatient psychiatric setting. The results also indicate that GEARS could be an effective treatment for adults with ADHD who are also experiencing problems with emotion regulation. However, a randomized controlled trial is needed to further evaluate the effectiveness of this new treatment.
