Prevalence and comorbidities of disruptive mood dysregulation disorder

IntroductionFollowing the release of DSM-5 in 2013, a newly introduced diagnostic category emerged in psychiatric classification—the disruptive mood dysregulation disorder (DMDD). DMDD is a depressive disorder that begins in childhood and is marked by a consistently irritable or angry mood, frequently accompanied by temper outbursts that are notably severe.ObjectivesIt is to study the prevalence and comorbidities of DMDD in Morocco, specifically at Arrazi University Psychiatric HospitalMethodsData were collected from youths aged 6 to 18 years who underwent a systematic assessment of symptoms. This assessment was extended to all patients consulting at Arrazi Hospital in Salé within the pediatric department over a period of four months (sample accrued from July 2023 to October 2023). The diagnosis of DMDD was established utilizing the diagnostic criteria outlined in DSM-5ResultsAbout 31% of the young participants met the operational criteria for DMDD. Those with DMDD exhibited increased comorbidity rates with attention-deficit/hyperactivity disorder (ADHD), another Depressive disorder and conduct disorder compared to those without DMDD. Additionally, they displayed elevated symptoms of aggressive behavior, rule-breaking, social issues, anxiety/depression, attention problems, and thought problems in comparison to all other participants without DMDD. It’s noteworthy that youth with DMDD presented with at least one psychiatric comorbidity.ConclusionsGiven that DMDD is accompanied by other comorbid psychiatric disorders, particularly depression and anxiety, and appears to impact familial and occupational status in adulthood, the early detection and subsequent effective treatment of DMDD symptoms are of utmost importance.Disclosure of InterestNone Declared

A Delphi consensus among experts on assessment and treatment of disruptive mood dysregulation disorder.

The aim of this study was to explore consensus among clinicians and researchers on how to assess and treat Disruptive Mood Dysregulation Disorder (DMDD). The Delphi method was used to organize data collected from an initial sample of 23 child psychiatrists and psychologists. Three rounds of closed/open questions were needed to achieve the objective. Fifteen experts in the field completed the whole study. Finally, 122 proposals were validated and 5 were rejected. Globally, consensus was more easily reached on items regarding assessment than on those regarding treatment. Specifically, experts agreed that intensity, frequency, and impact of DMDD symptoms needed to be measured across settings, including with parents, siblings, peers, and teachers. While a low level of consensus emerged regarding optimal pharmacological treatment, the use of psychoeducation, behavior-focused therapies (e.g., dialectical behavior therapy, chain analysis, exposure, relaxation), and systemic approaches (parent management training, family therapy, parent-child interaction therapy) met with a high degree of consensus. This study presents recommendations that reached a certain degree of consensus among researchers and clinicians regarding the assessment and treatment of youths with DMDD. These findings may be useful to clinicians working with this population and to researchers since they also highlight non-consensual areas that need to be further investigated.

Disruptive Mood Dysregulation Disorder and its Ayurvedic Management - A Case Report

Disruptive Mood Dysregulation Disorder (DMDD) is a condition in which children or adolescents experience ongoing irritability, anger, and frequent, intense temper outbursts. The symptoms of DMDD go beyond a “bad mood.” DMDD symptoms are severe. Youth who have DMDD experience significant problems at home, school, and often with peers. They also tend to have high rates of health care service use, hospitalization, and school suspension, and are more likely to develop other mood disorders. The present case of a 13 year old girl has worsening of mood characterized by irritability, anger, harming parent, crying spells, poor self care, social withdrawal for 12 months. The symptoms were increasing progressively and which badly affected her daily routine activities and school life. Here had never been a distinct period lasting more than one day during which the full symptom criteria, for a manic, hypomanic or a depressive episode had been met. In Ayurveda, the condition was diagnosed as Vathaja Unmada with Pithanubandha based on the symptoms of irritability anger etc. The treatment protocol including Snehapana, Virechana, Vasthi and Nasya was administered. During the treatment period family therapy methods also administered. After the intervention the symptoms were improved.

Household Food Insecurity Is Associated with Symptoms of Emotional Dysregulation in Children with Attention Deficit Hyperactivity Disorder: The MADDY Study.

The association of household food insecurity with symptoms of attention deficit hyperactivity disorder (ADHD) and emotional dysregulation in children was examined in this study. We utilized baseline data from 134 children aged 6–12 years who were enrolled in a clinical trial investigating multinutrient supplementation as a treatment for ADHD and emotional dysregulation. Household food security status was assessed using the 18-item US Household Food Security Survey Module. The symptoms of ADHD and emotional dysregulation disorders (oppositional defiant disorder (ODD) and disruptive mood dysregulation disorder (DMDD)) were assessed using the Child and Adolescent Symptom Inventory-5 and other comorbid emotional dysregulation symptoms were assessed using the Strengths and Difficulties Questionnaire (SDQ). Multiple linear regression determined associations between household food security status and symptoms of ADHD, ODD and DMDD, emotional symptoms and conduct problems. Household food insecurity was associated with more severe emotional symptoms (β = 2.30; 95% CI = 0.87–3.73; p = 0.002), conduct problems (β = 1.15; 95% CI = 0.01–2.30; p = 0.049) and total difficulties scores (β = 4.59; 95% CI = 1.82–7.37; p = 0.001) after adjusting for covariates (child’s sex, parent marital status, household income, parental anxiety and other parental psychopathology). In unadjusted analyses, household food insecurity was also associated with increased ODD (β = 0.58; 95% CI = 0.21–0.95; p = 0.003) and DMDD symptoms (β = 0.69; 95% CI = 0.20–1.19; p = 0.006), but these associations attenuated to non-significance after adjusting for all covariates. Household food insecurity was associated with more severe emotional dysregulation symptoms. Discussing and addressing food insecurity may be appropriate initial steps for youths with ADHD and emotional dysregulation.

Diet Quality As It Relates to ADHD and Emotional Dysregulation Symptoms in a Pediatric Population

Abstract Objectives Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder with a US pediatric prevalence of 10%. It presents with inattention and hyperactivity/impulsivity as well as emotional dysregulation (ED) symptoms such as irritability and defiant behavior, typical of Oppositional Defiance Disorder (ODD) and Disruptive Mood Dysregulation Disorder (DMDD). The etiology of ADHD is multi-factorial with suggested effects related to diet. Building on prior studies, this study examines the association of diet quality with ADHD and ED symptoms among a pediatric population. Methods This cross-sectional study utilized baseline data for 134 children aged 6–12 years with symptoms of ADHD and ED enrolled in an RCT of multinutrient supplementation. Diet quality was based on Healthy Eating Index-2015 (HEI) determined from the Vioscreen FFQ. ADHD, ODD, and DMDD symptoms were assessed using the Child and Adolescent Symptom Inventory-5. Other ED symptoms were assessed using the Strengths and Difficulties Questionnaire. Analysis for association was conducted using linear regression models, adjusting for covariates when necessary. Results Family income level was significantly associated with severity of inattention (P = 0.04), emotional problems (P = 0.01), conduct problems (P = 0.002), along with ODD (P = 0.004) and DMDD (P = 0.005) symptoms. Mean HEI score was 63.4 (SD = 8.8) and it was not significantly associated with any of the outcome symptoms. However, scores of HEI components vegetables (β = −0.118, P = 0.016) and refined grains (β = 0.052, P = 0.017) were both associated with inattention even after adjusting for covariates. Similarly, total fruit (β = −0.423, P = 0.037) was associated with conduct problems after adjusting for covariates. Conclusions While better vegetable and total fruit scores were associated with better symptoms in aspects of ADHD and emotional dysregulation, overall diet quality was not associated with inattention, hyperactivity/impulsivity, and ED symptoms severity among this cohort of children. Our findings could be explained by the fact that our study sample had a good diet quality and were only mildly impaired in their ADHD and ED symptoms.

The Use of Standard Parenting Management Training in Addressing Disruptive Mood Dysregulation Disorder: A Pilot Study

Parent management training has demonstrated effectiveness in the treatment of child behavioural issues and associated conduct difficulties. Anger, aggression, and irritability are common symptoms amongst children presenting with disruptive mood dysregulation disorder. Currently, there are no well-established evidence-based interventions for children presenting with symptoms of disruptive mood dysregulation disorder. This pilot study aims to assess if a standard, well-established, parent management training program (group Triple P) may be effective in addressing disruptive mood dysregulation disorder symptoms. Thirteen parents of children who presented with disruptive mood dysregulation disorder or subthreshold symptoms completed the Triple P behavioural management program (Level 4). Post-treatment, parents reported no significant change on childhood irritability. However, parents noted significant improvement on child overt aggression, behavioural difficulties and an increase in child pro-social behaviours. Despite the many limitations inherent in this pilot study, results suggest that standard parent management training may be useful in addressing overt aggression but not irritability.

Heritability, stability, and prevalence of tonic and phasic irritability as indicators of disruptive mood dysregulation disorder.

Little is known about genetic and environmental influences on the components of disruptive mood dysregulation disorder (DMDD), tonic irritability (i.e., irritable mood) and phasic irritability (i.e., temper outbursts). This study examined prevalence, stability, and heritability of tonic irritability, phasic irritability, and a DMDD proxy (pDMDD) based on DSM-5 criteria. pDMDD was derived using data from clinical interviews of parents and their twins (N=1,431 twin pairs), ages 8-17, participating in Waves 1 and 2 of the Virginia Twin Study of Adolescent Behavioral Development. Biometrical modeling was used to compare a common pathway model (CPM) and an independent pathway model (IPM), and heritability estimates were obtained for pDMDD using the symptoms of irritable mood (tonic irritability; DMDD Criterion D), intense temper outbursts (phasic irritability; DMDD Criterion A), and frequent temper outbursts (phasic irritability; DMDD Criterion C). Lifetime prevalence of pDMDD was 7.46%. The stability of DMDD symptoms and the pDMDD phenotype across approximately one year were moderate (.30-.69). A CPM was a better fit to the data than an IPM. Phasic irritability loaded strongly onto the pDMDD latent factor (.89-.96) whereas tonic irritability did not (.28). Genetic influences accounted for approximately 59% of the variance in the latent pDMDD phenotype, with the remaining 41% of the variance due to unique environmental effects. The heritability of tonic irritability (54%) was slightly lower than that of frequent and intense temper (components of phasic irritability; 61% and 63%, respectively). Compared to tonic irritability, phasic irritability appears to be slightly more stable and heritable, as well as a stronger indicator of the latent factor. Furthermore, environmental experiences appear to play a substantial role in the development of irritability and DMDD, and researchers should seek to elucidate these mechanisms in future work.

Disruptive Mood Dysregulation Disorder in Juvenile Justice.

Disruptive mood dysregulation disorder (DMDD) is a new diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). We compared juvenile justice involved youths with DMDD to those with disruptive behavior disorders (DBDs) and other mood disorders, to clarify the differences and to investigate differential correlates to DMDD relative to DBDs or mood disorders. Diagnostic and demographic data were available for 9,819 youths served by 57 juvenile justice sites. A subsample of 2,498 youths had data relevant to our study. The youths self-assessed mental health status on the Voice Diagnostic Interview Schedule for Children (V-DISC), and we retrofitted the V-DISC data to derive an approximate DMDD diagnosis. The retrofitted criteria for DMDD were met by 3.3 percent of justice-involved youths. Results from multinomial regression showed that, after adjustment for covariates, those with DMDD had fewer differences compared with those with other mood disorders than did those meeting criteria for DBDs. Consistent with the DSM-5 classification of DMDD as a depressive disorder, those with DMDD shared more characteristics with youths with mood disorders than with those reporting DBDs. Externalizing behaviors leading to justice involvement may overshadow internalizing symptoms of DMDD, but mood-related conditions should be identified and treated in this population.

Prevalence Rate and Course of Symptoms of Disruptive Mood Dysregulation Disorder (DMDD).

According to DSM-5, Disruptive Mood Dysregulation Disorder (DMDD) is characterized by chronic temper outbursts and irritable moods. So far, little is known about its prevalence rate, course and influence on individual well-being. We assessed the prevalence rates of DMDD symptoms during adulthood and primary school age - the latter retrospectively - and studied their relationship with psychiatric disorders and socioeconomic variables. A total of 2,413 subjects, aged 18-94 years, participated in this population-based, representative study based on self-reports. 12 (0.50 %) subjects reported elevated DMDD symptoms during adulthood, and 19 (0.79 %) reported elevated DMDD symptoms during primary school age. DMDD symptoms were associated with higher rates of depression and anxiety symptoms. Those reporting elevated DMDD symptoms during adulthood were more often single or divorced, and those reporting elevated DMDD symptoms during primary school age were more often childless and unemployed during adulthood compared to subjects without DMDD symptoms. DMDD symptoms seem to show a chronic course and go hand in hand with elevated psychiatric symptoms and impaired socioeconomic and demographic status.

Disruptive Mood Dysregulation Disorder Symptoms by Age in Autism, ADHD, and General Population Samples

ABSTRACTDisruptive mood dysregulation disorder (DMDD) is a controversial DSM-5 diagnosis. It is not known how DMDD symptoms vary by age and if differences are similar for autism, ADHD, and general population samples. Our study analyzed the two DMDD symptoms (irritable-angry mood and temper outbursts) in 1,827 children with autism or ADHD (with or without oppositional defiant disorder/ODD) and 657 general-population children 2–16 years of age. DMDD symptoms were rated by mothers on the Pediatric Behavior Scale. For all age groups, mean DMDD scores were less than sometimes a problem in the general population and ADHD-Inattentive (ADHD-I) samples, greater than sometimes but less than often a problem in autism and ADHD-Combined (ADHD-C), and greater than often a problem in children with autism or ADHD who also had ODD. DMDD symptoms were unrelated to age in children six and older. Preschool children with ADHD-C, ADHD-I, and ODD had more DMDD symptoms than school-age children, but DMDD symptoms did not differ by age in autism. DMDD symptoms were found in 45% of children with autism and were common at all ages. Evidence-based interventions are discussed.

The association between Disruptive Mood Dysregulation Disorder symptoms and sleep problems in children with and without ADHD

BackgroundMany youth experience persistent irritability and recurrent temper outbursts, conceptualized by DSM-5 as Disruptive Mood Dysregulation Disorder (DMDD). Sleep deprivation impairs emotion regulation which could increase rates of DMDD symptoms, especially in those with preexisting regulatory impairments, as seen with ADHD. However, there has been little examination of the relationship between chronic sleep problems and DMDD symptoms. MethodsAssociations between DMDD symptoms and sleep parameters in children were assessed using parent-report and objective measures of sleep in a general population sample (N = 665) and an ADHD sample (N = 784). Irritability, temper outbursts, sleep problems and other psychological problems were assessed with the Pediatric Behavior Scale. The general population study also completed overnight polysomnography (PSG). ResultsDMDD symptoms were reported in 9.2% of the community sample and 31.4% of the ADHD sample. In both samples, children with DMDD symptoms had significantly higher parent-reported sleep problems than children without DMDD symptoms. Children with sleep problems had significantly higher DMDD scores than children without sleep problems. However, DMDD symptoms were most strongly associated with oppositional behavior. Sleep problems were not a significant contributor. Hyperactivity-impulsivity was most strongly associated with sleep problems, and DMDD was not a significant contributor. Children with and without DMDD symptoms did not differ significantly on any PSG parameter. ConclusionsAssociations between parent-reported sleep problems and DMDD symptoms were due to their shared relationship with other behavioral problems. Therefore, chronic sleep problems do not appear to be a primary source of DMDD symptoms in children with or without ADHD.

8.2 The Impact of Disruptive Mood Dysregulation Disordersymptoms On the Treatment Course of Pediatric Attention-Deficit/Hyperactivity Disorder

Evidence-based treatments for youths with severely dysregulated mood: a qualitative systematic review of trials for SMD and DMDD.

The aim of this literature review was to examine the evidence for psychotherapeutic and pharmacological treatments in subjects with severely dysregulated mood and to identify potential areas for improvements in research designs. A literature search was conducted using several databases for published (PubMed, PsycINFO) and ongoing (clinical trial registries) studies conducted in youths who met NIMH's criteria for Severe Mood Dysregulation (SMD) or the DSM-5 diagnosis of Disruptive Mood Dysregulation Disorder (DMDD). Eight completed studies were identified: three randomized trials, four open pilot studies and one case report. Seven ongoing studies were found in trial registries. The available evidence suggests potential efficacy of psychotherapies which have previously been developed for internalizing and externalizing disorders. The two main pharmacological strategies tested are, first, a monotherapy of psychostimulant or atypical antipsychotic such as risperidone, already used in the treatment of severe irritability in youths with developmental disorders; and second, the use of a serotonergic antidepressant as an add-on therapy in youths treated with psychostimulant. Ongoing studies will further clarify the effectiveness of psychotherapeutic interventions for DMDD individuals and whether they should be given alone or in conjunction with other treatments. The short duration of the trials for a chronic disorder, the low number of studies, the lack of placebo or active comparator arm, and restrictive inclusion criteria in most of the controlled trials dramatically limit the interpretation of the results. Finally, future research should be conducted across multiple sites, with standardized procedures to measure DMDD symptoms reduction, and include a run-in period to limit placebo effect.

Demographic Differences in Disruptive Mood Dysregulation Disorder Symptoms in ADHD, Autism, and General Population Samples

Objective: Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) disruptive mood dysregulation disorder (DMDD) is a controversial new diagnosis. No studies have investigated DMDD symptoms (irritable-angry mood and temper outbursts) and demographics in general population and psychiatric samples. Method: Maternal ratings of DMDD symptoms and diagnoses, age, gender, IQ, race, and parent occupation were analyzed in general population (n = 665, 6-12 years) and psychiatric samples (n = 2,256, 2-16 years). Results: Percentage of school-age children with DMDD symptoms were 9% general population, 12% ADHD-I, 39% ADHD-C, and 43% autism. Male, nonprofessional parent, and autism with IQ > 80 were associated with increasing DMDD symptoms, but demographics together explained only 2% to 3% of the DMDD score variance. Conclusion: Demographics contributed little to the presence of DMDD symptoms in all groups, whereas oppositional defiant disorder (ODD) explained most of the variance. Almost all children with DMDD symptoms had ODD suggesting that DMDD may not be distinct from ODD.

Temper Loss and Persistent Irritability in Preschoolers: Implications for Diagnosing Disruptive Mood Dysregulation Disorder in Early Childhood.

Disruptive Mood Dysregulation Disorder (DMDD) is a new and controversial child psychiatric disorder characterized by persistent irritability and frequent temper loss. Among the controversies surrounding DMDD is whether the age of onset criterion-that DMDD may not be diagnosed before age 6years-is justified. This study examined DMDD symptoms and associated patterns of psychiatric comorbidity, behavioral, and family functioning in a sample of 139 preschoolers (ages 4-0 to 5-11years) admitted to an early childhood psychiatric day treatment program. DMDD symptoms were common in this acute clinical sample, with 63 children (45.3%) presenting with frequent temper outbursts and chronic irritability. As compared to children who did not present with DMDD symptoms, these children demonstrated more aggression and emotional reactivity and lower receptive language skills, with high rates of comorbidity with the disruptive behavior disorders. Findings contribute to an emerging literature on preschool DMDD, with implications for early childhood psychiatric assessment and clinical interventions.

Longitudinal Associations Between Preschool Disruptive Mood Dysregulation Disorder Symptoms and Neural Reactivity to Monetary Reward During Preadolescence.

Reward-processing abnormalities are thought to be a key feature of various psychiatric disorders and may also play a role in disruptive mood dysregulation disorder (DMDD), a new diagnosis in DSM-5. In the current study, we used event-related potentials (ERP) sensitive to monetary gains (i.e., the reward positivity [RewP]) and losses (i.e., the N200) to examine associations between symptoms of DMDD during early childhood and later reward processing during preadolescence. To assess early emerging DMDD symptoms in a large longitudinal community sample (n=373) of 3-year old children, we administered a diagnostic interview, Preschool Age Psychiatric Assessment (PAPA) with parents. At a later assessment, ∼6 years later, children completed a monetary reward task while an electroencephalogram (EEG) was recorded. Children's lifetime history of psychopathology was also assessed at that time using Kiddie-Schedule of Affective Disorders and Schizophrenia (K-SADS) with the child and parent. Multiple regression analyses revealed that age 3 DMDD symptoms predicted an enhanced RewP to monetary rewards in preadolescence. This association is independent of demographics and lifetime history of symptoms of depression, any anxiety disorder, attention-deficit disorder, oppositional defiant disorder, or conduct disorder Conclusions: Early manifestations of DMDD in children as young as 3 years old predicted enhanced reward processing later in development. These findings add to the growing corpus of literature on the pathophysiology of DMDD, and underscore the predictive validity of preschool DMDD on a neural level.
