For examples, youths with DMDD may selectively attend to negative social cues (e.g., others scowling, teasing) and minimize all other information about the social events. They may also misinterpret the emotional displays of others, believing others benign actions to be hostile or threatening. Consequently, they may be more likely than their peers to act in impulsive and angry ways.Children with DMDD may also have difficulty regulating negative emotions once they are elicited. To study these problems with emotion regulation, researchers asked children with DMDD to play computer games that are rigged so that children will lose. While playing these games, children with DMDD report more agitation and negative emotional arousal than their typically developing peers. Furthermore, youths with DMDD showed markedly greater activity in the medial frontal gyrus and anterior cingulate cortex compared to other youths. These brain regions are important because they are involved in evaluating and processing negative emotions, monitoring ones own emotional state, and selecting an effective response when upset, angry, or frustrated. Altogether, these findings suggest that youths with DMDD are more strongly influenced by negative events than other youths. They may become more upset and select less effective and socially acceptable ways to deal with negative emotions when they arise. Treatment
Medication
Evidence for treatment is weak, and treatment is determined based on the physicians response to the symptoms that people with DMDD present.
Consequently, the developers of DSM-5 created a new diagnostic label, DMDD, to describe children with persistent irritability and angry outbursts. In 2013, the American Psychiatric Association (APA) added DMDD to the DSM-5 and classified it as a depressive disorder. == References ==
