Disruptive Mood Dysregulation Disorder ( DMDD) is a disorder in the depressive disorder domain of the DSM 5. DMDD was originally conceived of as Severed Mood Dysregulation (SMD) and then criteria of hyper arousal was removed at the last minute. This diagnosis was introduced due to over diagnosis of Bipolar Disorder in youth but in many cases has created more confusion. The diagnosis is controversial because it lacks valid empirical studies and has an absence of guidelines for medical treatment.Some have gone so far as to express alarm that children may be falsely diagnosed with a mental health condition when they don’t have one. This is concerning especially if these children are prescribed medication. In response to mounting evidence, the ICD 11 will have DMDD as a diagnostic specifier of Oppostional Defiant Disorder. It will no longer be a separate diagnosis or a disorder under the depressive disorder domain.
DMDD co occurs with ADHD, autism spectrum disorder, and anxiety. Your child cannot carry a diagnosis of intermittent explosive disorder, oppositional defiant disorder, or bipolar disorder if they have DMDD. If your child has major depressive disorder, the symptoms they are displaying of DMDD must be present before the major depressive disorder, and after the major depressive disorder.
It’s important to note that your child who has DMDD may not be diagnosed correctly. If they are not, these facts are not relevant.
Much has been speculate about the relationship between DMDD and Bipolar disorder. Its important to note that the chronic irritability that is required for the diagnosis of DMDD has not been found to be a predictor of bipolar disorder. The chronic irritability seen in DMDD is related to behavioral problems in early adolescence and later generalized anxiety. As a child becomes an adult it seems to be related to unipolar depression.
Episodic irritability has been linked to later bipolar disorder.
What else we know about the difference between Bipolar disorder and DMDD?
We know that the neural circuits responsible for attention deficits seem different between (DMDD) and Bipolar disorder.
In DMDD the circuits seem show a deficiency in bottom up attention processing. In bipolar disorder the deficiency is primarily one that is in executive functioning and is top down. Also, studies show different neural pathways to negative affect in DMDD versus bipolar disorder.
Inability to read emotional cues
In children who have DMDD they demonstrate hyperarousal when they find stimuli frustrating. Both children who have bipolar disorder and DMDD show a dysfunction in emotional processing that is related to reading aggression in neutral responses. It appears that fear is triggered because facial expressions can’t help them identify emotions in others. This difficulty has been identified to be worse in those with DMDD. They show abnormal amygdala activation when performing facial recognition tasks. Bipolar disordered patients seem to primarily have difficulty only when shown fearful facial patterns.
What are some of the characteristics that youth with DMDD have in common?
These youth are more likely to:
Social risk factors for DMDD
These youth are more likely to:
Risk factors for DMDD
In the past, the fear was that antidepressants and stimulants would cause mania, but the belief is now that psychostimulants, antidepressants, SSRIs and SNRIs are good for treating chronic irritability.
Other drugs with a good outcome on irritability and depression are atypical antipsychotics and if ADHD is present methylphenidate. In some cases, clonidine, guanfacine, lithium, and anticonvulsants are used.
Behavioral Therapy, Parent Training, and DBT- C are currently recommended treatments.
Behavioral therapies teach children different methods of responding to situations more positively and this would involve parents. Parent training would teach parents ways to examine and explore their behaviors to facilitate more positive responses.
Therapy that is effective with emotional regulation and oppositional defiant disorder would likely also be effective with children categorized as ODD.
What is DBT C? It is a special form of DBT for children It consists of:
One randomized control trial found DBT C for the treatment of DMDD is a successful treatment. This makes sense because emotional dysregulation is a feature of DMDD and DBT targets this deficit. 43 children 7-12 were randomly assigned to DBT-C or Treatment as usual (TAU. All were stable on meds for 6 weeks and could be treated, outpatient. They were assessed by blinded raters and after 8, 16, 2 and 3 months follow up. The Clinical Global Impression Improvement scale was used focusing on improvement in behavior outbursts and angry irritable mood.
The results of this study showed treatment satisfaction was significantly higher in the DBT-C group with 90.4 participants satisfied compared to 36 in the other group.
