Summary
Optimizing stimulant monotherapy effectively reduces aggression in children with ADHD and conduct disorders. This approach often avoids the need for additional medications, particularly for boys with severe symptoms.
Area of Science:
- Child and Adolescent Psychiatry
- Neurodevelopmental Disorders
- Behavioral Therapy
Background:
- Attention-deficit/hyperactivity disorder (ADHD) in children is often comorbid with oppositional defiant disorder or conduct disorder.
- Aggressive behavior in these children can be challenging to manage, even with stimulant monotherapy.
- Identifying factors predicting response to stimulant optimization is crucial for effective treatment.
Purpose of the Study:
- To investigate factors associated with aggression that responds versus is refractory to individualized stimulant monotherapy optimization in children with ADHD.
- To compare treatment, demographic, and psychopathology differences between children with stimulant-responsive and stimulant-refractory aggression.
Main Methods:
- Children (6-13 years) with ADHD, conduct or oppositional defiant disorder, and significant aggression underwent open stimulant monotherapy optimization.
- Stimulant titration was guided by weekly assessments of behavior and tolerability, alongside behavioral therapy for families.
- The Retrospective-Modified Overt Aggression Scale (R-MOAS) was used to classify aggression as stimulant-responsive or refractory.
Main Results:
- Aggression was sufficiently reduced in 49.3% of children (32/65) with stimulant monotherapy and behavioral therapy, avoiding adjunctive medication.
- Stimulant responders were more likely to benefit from a specific methylphenidate preparation and required fewer behavioral therapy sessions.
- Boys, particularly those with higher baseline aggression and depressive/manic symptoms, were more prone to stimulant-refractory aggression.
Conclusions:
- Systematic, monitored stimulant monotherapy titration can significantly reduce aggression in children with ADHD and comorbid disorders.
- This optimized monotherapy approach often obviates the need for additional medications.
- Careful titration is effective even in children with a history of insufficient response to prior stimulant treatments.

01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

01:28Conduct Disorder
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
01:30Oppositional Defiant Disorder
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

01:30Adrenergic Agonists: Therapeutic Uses
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

01:25Adrenergic Agonists: Indirect-Acting Agents
Indirect-acting adrenergic agonists potentiate the effects of endogenous catecholamines through different mechanisms without directly binding to adrenoceptors.
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...

01:24Operant Conditioning Intervention
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
