Chapter 21: Impulse Control Disorders

Major disorders discussed include Oppositional Defiant Disorder (ODD), Conduct Disorder (CD), and Intermittent Explosive Disorder (IED), with additional attention given to pyromania and kleptomania. ODD is defined by angry, irritable moods and defiant behavior, while CD is a more severe pattern involving chronic violation of the rights of others, destruction of property, and aggression toward people or animals, sometimes presenting with dangerous callous and unemotional traits. Conduct disorder features distinct subtypes based on onset age, and the childhood-onset type is often predictive of Antisocial Personality Disorder in adulthood. IED manifests as recurrent, unwarranted, explosive outbursts that are followed by feelings of remorse, and it is linked to general emotional dysregulation. The development of these disorders is attributed to a complex interplay of risk factors, including genetic predisposition, specific neurobiological deficits such as reduced gray matter density in the prefrontal cortex and abnormal functioning of the amygdala, and significant environmental stressors, particularly Adverse Childhood Experiences (ACEs) and inconsistent parenting. Nursing intervention priorities center on establishing a climate of safety, building rapport, and setting firm, consistent limits, all within a trauma-informed care framework. Due to high rates of impulsivity and aggression, continual assessment for suicide and violence risk is crucial. Caregivers and staff are taught to utilize low expressed emotion to avoid confrontation and reduce patient reactivity. Treatment generally combines pharmacotherapy, often using off-label medications like mood stabilizers or second-generation antipsychotics to manage target symptoms like aggression, with specialized psychosocial interventions, including Cognitive Behavioral Therapy (CBT), Dialectical Behavioral Therapy (DBT), Parent Management Training (PMT), and the intensive, community-based approach of Multisystemic Therapy (MST).
