Disruptive Mood Dysregulation Disorder: A New Diagnosis for Children with Severe Irritability

Disruptive mood dysregulation disorder (DMDD) is a mental health condition that affects children and adolescents.

It is characterized by frequent and severe temper outbursts that are out of proportion to the situation and inconsistent with the child’s developmental level. Children with DMDD also have a persistent irritable or angry mood that lasts most of the day, nearly every day.

Disruptive Mood Dysregulation Disorder can cause significant distress and impairment in the child’s family, school, and social life. It can also increase the risk of developing other mental disorders, such as depression, anxiety, and bipolar disorder, in adulthood. Therefore, it is important to recognize the signs and symptoms of DMDD and seek professional help as soon as possible.

For more information about DMDD, you can visit the National Institute of Mental Health website, where you can find a fact sheet, a brochure, and the latest research updates on this condition.

What Causes Disruptive Mood Dysregulation Disorder?

The exact causes of DMDD are not fully understood, but researchers believe that it is a complex interaction of biological, psychological, and environmental factors. Some of the possible factors that may contribute to Disruptive Mood Dysregulation Disorder include:

• Genetics: Children who have a family history of mood disorders, such as depression or bipolar disorder, may have a higher chance of developing DMDD.
• Brain structure and function: Children with DMDD may have abnormalities in the brain regions that regulate emotions, impulses, and stress responses, such as the amygdala, prefrontal cortex, and hippocampus.
• Neurotransmitters: Children with DMDD may have imbalances in the brain chemicals that transmit signals between nerve cells, such as serotonin, dopamine, and norepinephrine.
• Temperament: Children who have a difficult temperament, such as being highly sensitive, reactive, or inflexible, may be more prone to DMDD.
• Stress and trauma: Children who experience chronic stress, abuse, neglect, or other traumatic events may develop DMDD as a way of coping with their negative emotions.
• Parenting style: Children who have inconsistent, harsh, or permissive parents may develop DMDD due to a lack of clear boundaries, expectations, and emotional support.

How is DMDD Diagnosed?

DMDD is diagnosed by a mental health professional, such as a psychiatrist, psychologist, or pediatrician, based on the criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). To be diagnosed with Disruptive Mood Dysregulation Disorder, a child must meet the following criteria:

• The child has severe recurrent temper outbursts that are verbal or physical, such as yelling, hitting, kicking, or throwing things, at least three times a week, on average, for more than a year.
• The temper outbursts are out of proportion to the situation and the child’s age and developmental level.
• The child has a persistent irritable or angry mood that is noticeable by others, such as parents, teachers, or peers, most of the day, nearly every day, for more than a year.
• The symptoms occur in at least two settings, such as home, school, or with friends, and cause significant problems in the child’s functioning.
• The child is between 6 and 18 years old, and the symptoms start before the age of 10.
• The symptoms are not caused by another mental disorder, such as bipolar disorder, oppositional defiant disorder, or autism spectrum disorder, or by a medical condition, such as a brain injury, thyroid disorder, or substance abuse.

To diagnose DMDD, the mental health professional will conduct a comprehensive evaluation that may include:

• A detailed interview with the child and the parents or caregivers, to gather information about the child’s medical history, family history, developmental history, behavioral patterns, emotional state, and social functioning.
• A physical examination and laboratory tests, to rule out any medical causes of the symptoms, such as infections, hormonal imbalances, or nutritional deficiencies.
• A psychological assessment, to measure the child’s cognitive abilities, personality traits, mood, anxiety, and coping skills, using standardized tests, questionnaires, or rating scales.
• An observation of the child’s behavior and interactions, in different settings and situations, such as at home, at school, or with peers, to evaluate the frequency, intensity, and duration of the temper outbursts and the irritable mood.
• A consultation with other professionals, such as teachers, counselors, or social workers, who may have relevant information about the child’s functioning and challenges.

How is DMDD Treated?

Disruptive Mood Dysregulation Disorder is a chronic and complex condition that requires a multimodal and individualized treatment plan that addresses the child’s biological, psychological, and environmental needs.

The main goals of treatment are to reduce the severity and frequency of the temper outbursts, improve the child’s mood and behavior, enhance the child’s social and academic skills, and prevent the development of other mental disorders. The treatment options for DMDD may include:

Medication

There is no specific medication that is approved for Disruptive Mood Dysregulation Disorder, but some medications that are used for other mood disorders, such as antidepressants, mood stabilizers, or antipsychotics, may help reduce the symptoms of DMDD.

However, medication should be used with caution, as it may have side effects, such as weight gain, sedation, or increased suici**dal thoughts, and it may not be effective for all children. Therefore, medication should be prescribed and monitored by a qualified psychiatrist, who can adjust the dosage and type of medication according to the child’s response and tolerance.

Psychotherapy

Psychotherapy, also known as talk therapy, is a process of exploring and changing the child’s thoughts, feelings, and behaviors that are related to Disruptive Mood Dysregulation Disorder.

Psychotherapy can help the child understand the causes and consequences of their condition, develop coping skills to manage their emotions and impulses, improve their self-esteem and confidence, and enhance their relationships with others.

Psychotherapy can be delivered individually, in a group, or with the family, depending on the child’s needs and preferences. Some of the common types of psychotherapy for DMDD are:

Cognitive-behavioral therapy (CBT

CBT is a type of psychotherapy that focuses on identifying and challenging the negative and distorted thoughts and beliefs that trigger and maintain the temper outbursts and the irritable mood.

CBT also teaches the child how to replace these thoughts with more realistic and positive ones, and how to use behavioral strategies, such as relaxation techniques, problem-solving skills, or reward systems, to cope with stressful situations and achieve their goals.

Dialectical behavior therapy (DBT)

DBT is a type of psychotherapy that combines the principles of CBT with the concepts of mindfulness, acceptance, and emotion regulation.

DBT helps the child learn how to accept their emotions without judging or suppressing them, and how to use skills, such as mindfulness, distress tolerance, interpersonal effectiveness, and emotion regulation, to manage their emotions and impulses, and to communicate and interact with others in a respectful and assertive way.

Interpersonal therapy (IPT)

IPT is a type of psychotherapy that focuses on improving the child’s relationships with others, such as parents, siblings, friends, or teachers.

IPT helps the child identify and resolve the interpersonal conflicts and difficulties that may contribute to their condition, such as separation, loss, rejection, or bullying. IPT also helps the child develop social skills, such as empathy, cooperation, or negotiation, to build and maintain healthy and supportive relationships.

Parent training

Parent training is a type of intervention that aims to educate and support the parents or caregivers of children with Disruptive Mood Dysregulation Disorder.

Parent training can help the parents understand the nature and causes of DMDD, recognize the signs and symptoms of the condition, and learn how to respond to the child’s temper outbursts and irritable mood in a consistent, calm, and positive way.

Parent training can also help the parents establish clear rules and expectations, provide appropriate rewards and consequences, and create a structured and predictable environment for the child. Parent training can also help the parents cope with their own stress and emotions, and seek help when needed.

School-based interventions

School-based interventions are programs or services that are provided by the school staff, such as teachers, counselors, or psychologists, to help children with Disruptive Mood Dysregulation Disorder succeed in their academic and social activities.

School-based interventions can help the child follow the school rules and routines, complete their assignments and homework, participate in class discussions and group projects, and interact with their classmates and teachers in a respectful and cooperative way.

School-based interventions can also help the child cope with the academic and social challenges and pressures, such as exams, grades, peer pressure, or bullying, that may trigger or worsen their condition.

School-based interventions can also involve collaborating with the parents and the mental health professionals to ensure the consistency and continuity of the child’s treatment plan.
