Neurodevelopmental Disorders

  • Diagnosis Challenges

    • Psychiatric Disorders

    • Difficulty in diagnosing children compared to adults.

    • Children lack abstract cognitive abilities and verbal skills, complicating the assessment.

    • Disorders are continuously evolving during childhood.

    • Similar issues as in adults include mood disorders, anxiety disorders, and eating disorders.

  • Neurodevelopmental Disorders Overview

    • Typically diagnosed in infancy or childhood; occasionally identified in adolescence.

Intellectual Developmental Disorder (IDD)

  • Onset

    • Occurs prior to age 18.

    • Characterized by impairments in intellectual performance and adaptive skills across various domains.

  • Characteristics of IDD

    • Challenges in communication skills.

    • Difficulties in self-care, social or interpersonal skills, and home living.

    • Struggles with using community resources and self-direction.

    • Issues in academic skills, leisure, health, and safety.

  • Evaluation Measures

    • General intellectual functioning assessed via clinical assessment and IQ tests.

    • Adaptive functioning indicates ability to adapt to daily living and societal expectations based on age and cultural background.

  • Causes of IDD

    • Various factors contribute to IDD:

    • Hereditary Conditions: Example - Tay-Sach’s disease.

    • Alterations in Embryonic Development: Examples - trisomy 21 (Down syndrome) or maternal alcohol intake.

    • Pregnancy/Perinatal Issues: Fetal malnutrition, hypoxia, infections, trauma.

    • Infancy Medical Conditions: Like infections and lead poisoning.

    • Environmental Factors: Lack of nurturing or stimulation.

    • In some cases, causation remains unknown.

  • Variations in Behavior

    • Individuals display a spectrum of mood and behavior, ranging from passive and dependent to aggressive and impulsive.

  • Nursing Assessment

    • It is critical for nurses to assess both strengths and limitations to promote client independence.

    • Family involvement in care planning is essential.

Autism Spectrum Disorder (ASD)

  • Defining Characteristics

    • Severe impairments in social interaction and communication, as well as restricted and stereotypical behavioral patterns.

    • Historically, pervasive developmental disorders (PDDs) are now seen on a continuum termed the autism spectrum, showing a range from mild to severe behaviors.

  • Onset

    • Typically evident by early childhood, between 18 months and 3 years.

    • Higher prevalence in boys.

  • Behavioral Indicators

    • Minimal eye contact.

    • Limited facial expressions and gestures for communication.

    • Difficulty relating to peers or parents; lack of spontaneous enjoyment.

    • Expressing no emotional affect.

    • Inability to engage in play scenarios or imaginative activities.

    • Often exhibit stereotyped motor behaviors (refer to Box 22.1).

  • Related Factors

    • Previously considered rare; now understood to have a genetic component.

    • Public health controversies concerning the measles, mumps, rubella (MMR) vaccine have been debunked, indicating no causal relationship with ASD.

    • Treatment typically focuses on enhancing communication skills and behavior management.

    • Goals include reducing behavioral symptoms and promoting learning and development, often utilizing special education, language therapy, cognitive-behavioral therapy, and targeting medications.

  • Co-Occurring Disorders

    • Commonly associated disorders include tic disorders, learning disorders, and various communication disorders.

Tic Disorders

  • Description

    • Sudden, rapid, recurrent, non-rhythmic motor movements or vocalizations.

    • Tourette Disorder: Characterized by multiple motor and one or more vocal tics.

    • Chronic Motor or Tic Disorder: Involves either motor or vocal tics, but not both.

  • Treatment

    • Managed with atypical antipsychotics such as risperidone or aripiprazole.

Learning Disorders

  • Definition

    • Achievements in reading, mathematics, or written expression fall below what’s expected based on the child’s age, formal education level, and overall intelligence.

  • Impact

    • Affect academic achievement and life activities, as well as self-esteem and social skills.

    • Early identification and intervention are crucial; absence of coexisting problems correlates with better outcomes.

Motor Skills Disorders

  • Developmental Coordination Disorder

    • Impacts coordination severely enough to interfere with academic performance and activities of daily living (ADLs).

    • Frequently coexists with communication disorders.

    • Interventions may include adaptive physical education and sensory integration therapies.

  • Stereotypic Movement Disorder

    • Characterized by rhythmic or repetitive behaviors, often resulting in self-inflicted injuries; pain does not deter these behaviors.

Communication Disorders

  • Characteristics

    • Language, speech, or communication deficits that significantly interfere with developmental milestones, academic success, or ADLs (including socialization).

    • Severity can vary.

  • Types

    • Language Disorder.

    • Speech Sound Disorder.

    • Stuttering.

    • Social Communication Disorder.

Elimination Disorders

  • Encopresis

    • Involuntary or intentional passage of feces into inappropriate places (child must be at least age 4).

  • Enuresis

    • Involuntary urination during day or night in clothing or bed (child must be at least age 5).

    • Intentional enuresis may be linked to disruptive behavior disorders.

    • Higher prevalence in boys than girls.

Attention-Deficit/Hyperactivity Disorder (ADHD)

  • Definition

    • Characterized by inattentiveness, hyperactivity, and impulsiveness.

    • Often diagnosed when the child begins school and exhibits symptoms such as fidgeting, disruptive behavior, and difficulty in task completion.

    • Potential for peer ostracism due to symptoms.

  • Etiology

    • Causes remain unclear.

    • Possible theories involve cortical-arousal, information-processing, or maturational abnormalities in the brain.

    • Environmental toxins, prenatal influences, hereditary factors, and actual brain damage may play roles.

    • Parental exposure to drugs and lead, and decreased metabolism in the frontal lobes are noted factors.

  • Treatment

    • No single treatment method has been conclusively effective.

    • Goals focus on managing symptoms, reducing hyperactivity and impulsivity, and enhancing attention.

    • Typically involves a combination of medication and behavioral, psychosocial, and educational interventions.

  • Medications

    • Stimulants: Examples include methylphenidate (Ritalin), amphetamine compound (Adderall), dextroamphetamine (Dexedrine), and pemoline (Cylert).

    • Antidepressants may serve as a secondary option.

  • Home and School Strategies

    • Implement consistent rewards and consequences for behavior.

    • Use different therapeutic play types to engage the child: dramatic play, creative play.

ADHD and Nursing Process

  • Assessment Components

    • History: Notable fussy behavior as an infant; perception of being “out of control”; difficulties across major life areas.

    • General Appearance and Motor Behavior: Inability to sit still; conversation challenges; abrupt topic changes.

    • Mood and Affect: Possible emotional lability; presence of anxiety, frustration, and agitation.

    • Thought Process: Disorganized or illogical thinking.

  • Further Assessment Considerations

    • Sensorium and Intellectual Processes: Impaired attention and concentration.

    • Judgment and Insight: Typically poor and impulsive.

    • Self-Concept: May struggle with low self-esteem, feeling inadequate due to behavioral responses.

    • Roles and Relationships: School and social difficulties.

    • Physiological and Self-Care: Issues with weight management; challenges with settling down or sleeping.

  • Data Analysis and Priorities

    • Potential Issues: Includes risk of injury, role fulfillment inadequacies, disruptive social interaction, and ineffective family coping.

    • Outcome Identification: Focus on client injury safety, boundary violations, social skills development, and successful task completion.

  • Nursing Actions

    • Focus on safety measures and improvements in role performance.

    • Simplify instructions and promote a structured daily routine.

    • Provide education and support to both the client and their family.

    • Regular evaluations to assess progress.

Mental Health Promotion

  • Early Detection and Intervention

    • Essential for success in managing various disorders.

    • Utilization of assessment tools such as the SNAP-IV Teacher and Parent Rating Scale for disorders including ADHD, Oppositional Defiant Disorder (ODD), conduct disorders, and depression.

    • The Connor Scale for ADHD Assessment, with versions for parents and teachers, aids in evaluation.

  • Misrepresentation of Scientific Knowledge

    • Reference to Dr. Andrew Wakefield and the discredited medical hoax regarding vaccinations and their supposed connection to autism.

Oppositional Defiant Disorder (ODD)

  • Definition

    • Defines an enduring pattern of uncooperative, defiant, disobedient, and hostile behaviors toward authority with no major violation of antisocial norms.

    • Common behaviors seen in children and adolescents (refer to Table 23.1).

  • Prevalence

    • Found in approximately 2% to 15% of adolescents, with an average of around 3% within the U.S.

    • Observed more frequently in males.

    • A combination of genetic, temperamental, and adverse social factors is believed to contribute to the development of ODD.

  • Prognosis

    • Varies significantly and is dependent on factors such as the age of onset, symptom severity, and presence of comorbid psychiatric conditions.

  • Nursing Role in Health Promotion

    • Early interventions may involve collaboration with various specialists including psychologists, pediatricians, physiotherapists, teachers, neurologists, families, speech therapists, and occupational therapists.
