Childhood Disorders: ADHD & Conduct Disorder

Important Terms Related to Childhood Disorders

  • Delinquent: Refers to criminal acts specifically committed by minors.

  • Juvenile Offenders: Delinquents who have been formally charged with a crime.

  • Juvenile Detention Center: A correctional facility designed for delinquents, often referred to as a prison for minors.

  • Neurodivergent: An umbrella term that recognizes neurological differences, such as ADHD, as natural variations in the human brain. This perspective emphasizes that these differences contribute to the diversity of human experience, bringing both unique strengths and limitations.

  • DSM (Diagnostic and Statistical Manual of Mental Disorders): A comprehensive classification system utilized by mental health professionals to diagnose and categorize various mental health conditions. Further details on the DSM will be covered later in the term.

Attention Deficit Hyperactivity Disorder (ADHD)

Categorized within the DSM as a neurodevelopmental disorder.

Prevalence and Characteristics

  • Global Prevalence: Affects approximately 5-7\% of children worldwide.

  • Comorbidity: About 50\% of individuals with an ADHD diagnosis also have at least one other co-occurring diagnosis.

  • Neurotype: ADHD is considered a neurotype, meaning it is fundamentally caused by differences in brain structure and function, primarily:

    • Lower levels of key neurotransmitters like dopamine and norepinephrine.

    • Structural differences in the brain, particularly in the pre-frontal cortex (PFC), which is crucial for executive functions.

  • Etiology: Caused by:

    • Genetic factors (it often runs in families).

    • Prenatal or neonatal environmental factors.

  • Misconceptions: ADHD is not caused by poor parenting, inadequate nutrition, or excessive screen time.

Main Symptoms

ADHD is characterized by a persistent pattern of symptoms across three core categories:

  1. Inattention

  2. Hyperactivity

  3. Impulsivity

Types of ADHD

There are three distinct presentations or types of ADHD:

  • Inattentive Type: Formerly known as ADD (Attention Deficit Disorder), primarily characterized by inattentive symptoms.

  • Hyper-Impulsive Type: Predominantly features symptoms of hyperactivity and impulsivity.

  • Combined Type: Individuals exhibit a significant number of symptoms from both the inattention and hyper-impulsivity categories.

Diagnostic Criteria

For a diagnosis of ADHD, two main criteria must be met:

  • Impairment Across Settings: Symptoms must cause significant impairment in at least 2+ settings (e.g., at home, at school, or with friends).

  • Early Onset: Symptoms must have been present prior to age 12.

Deeper Look into Symptom Categories

  • Inattention (NOT correlated with delinquency):

    • Easily distracted and problems with sustained focus.

    • Difficulty following instructions and challenges with organization.

    • Frequent forgetfulness in daily activities.

  • Hyperactivity (Examples):

    • Restlessness and fidgeting in situations where it's inappropriate to do so.

    • Excessive talking.

    • Climbing or running where it's not allowed or unsafe.

    • Inability to engage in quiet play or leisure activities.

    • In older teens and adults, hyperactivity may manifest as internal or mental restlessness rather than overt physical activity.

  • Impulsivity (Examples):

    • Blurting out answers before questions are completed.

    • Trouble waiting for turns.

    • Interrupting or intruding on others' conversations or activities.

    • Taking things without permission.

    • Engaging in dangerous activities due to a lack of forethought about potential risks.

ADHD and its Correlation with Criminal Behavior (Untreated)

When ADHD is left untreated, there is a notable correlation with increased involvement in criminal activities:

  • Juvenile Delinquency: Juveniles with untreated ADHD are 3x-10x more likely to be involved in criminal behavior compared to their neurotypical peers.

  • Adult Criminality: Approximately 20\% of adult criminals in prisons meet the diagnostic criteria for ADHD, irrespective of gender.

  • Gender-Specific Rates in Juvenile Justice: Up to 45\% of juvenile males and up to 19\% of juvenile females in correctional facilities have ADHD, significantly higher than the 5\% prevalence rate in the general population.

Conduct Disorder (CD)

CD is categorized under disruptive disorders in the DSM.

Definition and Characteristics

  • Core Definition: A repetitive and persistent pattern of behavior in which the basic rights of others, or major age-appropriate societal norms or rules, are violated.

  • Social Impact: Children and adolescents with CD are highly likely to be rejected by peers due to their behaviors, resulting in a significant lack of social skills development.

  • Prevalence: Approximately 5\% of children and adolescents can be diagnosed with CD.

DSM-5 CD Diagnostic Criteria

Diagnosis requires meeting specific criteria:

  • (A) Persistent Antisocial Behavior: The individual must exhibit at least 3+ of the following behaviors in the past 12 months, with at least one criterion present in the past 6 months, across four main categories:

    • Aggression to People and Animals: Bullying, threatening, fighting, using a weapon, physical cruelty to people or animals, forced sexual activity.

    • Destruction of Property: Deliberate fire-setting with intent to cause serious damage, deliberate destruction of others' property.

    • Deceitfulness or Theft: Breaking into property, lying to obtain goods/favors or to avoid obligations, shoplifting.

    • Serious Violations of Rules: Truancy (starting before age 13), running away from home overnight (at least twice or once if prolonged), staying out late at night (starting before age 13).

  • (B) Onset Age: The disturbance in behavior must cause clinically significant impairment in social, academic, or occupational functioning. Symptoms must be present before or at age 15.

DSM-5 CD Type: Callous-Unemotional (CU) Specifier

A specifier can be added to the CD diagnosis if the individual consistently displays at least 2+ of the following callous-unemotional traits over at least 12 months and in multiple settings, and these traits reflect the individual's typical interpersonal and emotional functioning:

  • Lack of Remorse or Guilt: Does not feel bad or guilty when doing something wrong, beyond feeling external consequences.

  • Lack of Empathy: Disregards and is unconcerned about the feelings of others.

  • Unconcerned About Performance: Shows no concern about poor performance at school, work, or in other important activities, despite evidence of poor performance (e.g., failing grades).

  • Shallow or Deficient Affect: Does not express feelings or show emotions to others, except in ways that seem shallow, dishonest, or superficial (e.g., using emotions to manipulate).

Differentiation: CD vs. CD with CU

Understanding the distinction between CD without CU traits and CD with CU traits is crucial for treatment and prognosis:

  • CD without Callous-Unemotional (CU) Traits:

    • Typically very emotional.

    • Tend to exhibit reactive aggression, meaning their aggressive outbursts are often responses to perceived threats or frustrations.

    • They must read emotional information from others to regulate their behavior and understand social cues.

  • CD with Callous-Unemotional (CU) Traits:

    • Characterized by being not emotional; they often lack genuine emotional responses.

    • They are typically not responsive to punishment, meaning punitive measures are often ineffective in altering their behavior.

    • Rewards motivate them more effectively than punishments, suggesting a different pathway for intervention.

Life Course Persistent Offenders - Moffitt's Theory

  • Moffitt's Theory on Life-Course Persistent Offenders: Developed by Terrie Moffitt, this theory posits that early-onset behavioral issues, particularly those stemming from untreated ADHD and/or Conduct Disorder, are key predictors of a criminal trajectory that persists across an individual's entire life course.

  • Progression of Antisocial Behavior (Illustrative Timeline):

    • Age 3: Early indicators may include unprovoked biting or hitting.

    • Age 10: Escalates to behaviors like truancy (skipping school).

    • Age 16: Further progression might involve drug dealing and/or car theft.

    • Age 22: More serious offenses like robbery and/or sexual assault may occur.

    • Age 30: By this age, the pattern could include white-collar crimes such as fraud and/or child abuse, demonstrating a consistent and escalating involvement in criminal activity across the lifespan.
