title: [Emotional dysfunctions in attention deficit hyperactivity disorder].
abstract: Inattention, motor instability, and impulsivity, associated in varying degrees of severity depending on the clinical subtype, constitute the key symptoms of attention deficit/hyperactivity disorder (ADHD). However, emotional symptoms are frequent in patients with ADHD and may, in some cases, be responsible for a major part of the negative impact on functioning and outcome. Emotional problems have been described in ADHD even in the absence of characterized comorbid conditions such as depressive or anxiety disorders. They can manifest acutely in the form of severe tantrums and aggressive behaviour, generally in reaction to an environmental trigger, or show a more chronic course of irritable or labile mood. Symptoms of emotional undercontrol seem to occur more frequently when ADHD is associated with oppositional defiant behaviour, but they are not specific and may contribute to difficulties in making a differential diagnosis, especially with bipolar disorder and prodromal symptoms of personality disorders. The frequency and negative impact of emotional symptoms and the need to differentiate them from bipolar disorder has led some authors to the description of a novel clinical entity called "severe mood dysregulation" or "temper dysregulation with dysphoria." This article aims to review the recent literature on emotional symptoms associated with ADHD and to discuss relevant clinical and biological issues. Current research highlights the links between emotional self-regulation and executive functions and possible involvement of motivational systems. The role of environmental factors in the development of emotional regulation and self-control is another important issue, especially because environmental modification is the major focus of current preventive and therapeutic interventions.
