Autism Spectrum Disorder Overview

Autism Spectrum Disorder

Description of Autism Spectrum Disorder

  • Autism Spectrum Disorder (ASD) is a complex set of neurodevelopmental syndromes characterized by:

    • Communication impairments: Difficulties with verbal and non-verbal communication, including challenges in understanding and using language.
    • Social withdrawal: Reduced interaction with others, and challenges in engaging in social relationships.
    • Repetitive and unusual physical behaviors: Actions such as hand-flapping, rocking, or other repetitive movements.

  • These symptoms may lead to significant social impairment affecting day-to-day life.

  • ASD encompasses various conditions previously diagnosed separately, including:

    • Childhood disintegrative disorder
    • Pervasive developmental disorder
    • Asperger's disorder

  • Associated conditions may include:

    • Epilepsy
    • Genetic disorders like Rett syndrome
    • Intellectual disabilities

  • Epidemiology:

    • More common in males compared to females
    • Increased prevalence among those born before 26 weeks of gestation
    • Higher risk for those with a family history of autism

  • Onset and progression:

    • Diagnosed typically in early childhood; signs may manifest as early as six months old
    • Symptoms are chronic and can persist into adulthood

  • Etiology:

    • Unknown causes; it is hypothesized that genetic, environmental, and perinatal factors may contribute to the development of ASD

Priority Assessments/Cues

  • Assessments should consider the individual’s placement on the autism spectrum, level of functionality, and amount of support required. Key areas to evaluate include:
    • Intellectual disability: Screen for any delays in cognitive development appropriate for age (accelerated, delayed, or normal development).
    • Social and relational difficulties: Notable challenges include:
    • Decreased interest in interpersonal relationships
    • Difficulty in imitating or engaging with others
    • Challenges in showing and receiving affection
    • Attachment issues
    • Reduced imaginative play
    • Empathy deficits and processing feelings of others
    • Inability to create and sustain friendships
    • Communication difficulties: This may include:
    • Problems with eye contact
    • Challenges in using and interpreting facial expressions and gestures
    • Difficulty in engaging in reciprocal conversations
    • Possible presence of echolalia (repeating words or phrases)
    • Use of idiosyncratic utterances and monotone speech
    • Physical activities and interests: Watch for:
    • Over- or under-sensitivity to sensory stimuli (especially sounds)
    • Irritability and compulsivity
    • Fascination with specific objects
    • Strong need for familiar routines and consistent environments
    • Restricted food preferences
    • Repetitive verbalizations and body movements (e.g., clapping, banging, rocking)
    • Self-injurious behaviors
    • Family dynamics: Altered dynamics may put a strain on relationships within the family and with caregivers and siblings.

Priority Laboratory Tests/Diagnostic Cues

  • Developmental testing indicating delays in language and social skills should be performed.
  • Assess sensory systems through hearing and vision tests to detect any potential deficits.
  • Conduct diagnostic tests to assess for potential comorbidities, including epilepsy.

Priority Interventions/Collaborative Actions

  • Ensure the client’s safety given potential high levels of physical activity coupled with cognitive challenges.
  • Create a safe and consistent environment conducive to learning and play.
  • Provide familiar objects and routines; include preferred foods where applicable.
  • Support positive interactions by:
    • Setting achievable social goals
    • Delivering clear, concrete instructions
    • Forming trusting relationships to convey acceptance
    • Reinforcing positive behaviors such as eye contact and socially acceptable actions
    • Being sensitive to touch, only engaging when the client indicates receptivity
  • Facilitate exposure to group learning and play based on individual tolerance.
  • Ensure a consistent caregiver presence, limited in number, to build trust and familiarity.
  • Encourage self-care habits and adapt activities to leverage each client’s individual strengths.

Priority Actual & Potential Complications/Cues

  • Be aware of the potential for misdiagnosis and incorrect treatment plans.
  • Avoid assumptions of low cognitive function solely based on communication impairments.

Priority Hypotheses for Nursing Care

  • Early diagnosis likely increases the effectiveness of interventions through timely support.
  • Provide assistance with symptoms of:
    • Self-injury
    • Aggression
    • Hyperactivity
    • Impulsivity
  • Recognize and support savant traits, where individuals may excel in music, art, puzzles, pattern recognition, design, or memory.
  • Acknowledge that children and adults with autism may require healthcare for other physical needs; nursing staff should be equipped and sensitive to these patients across their lifespan.

Priority Medications

  1. Risperidone

    • Oral antipsychotic with controversial use for managing irritability in children aged 5-15 years.
    • Important to monitor for:
      • Neuroleptic malignant syndrome
      • Tardive dyskinesia
      • Hyperglycemia/diabetes mellitus

  2. Aripiprazole

    • Oral antipsychotic with controversial use for managing irritability in children aged 6-17 years.
    • Possible side effects include:
      • Sedation
      • Fatigue
      • Weight gain
      • Drooling
      • Tremoring

Priority Teaching/Discharge Needs

  • Effective ongoing health management will require continuous healthcare and behavioral surveillance, involving collaboration with schools, caregivers, family members, and health providers.
  • Support should be sustained as the child grows and developmental needs change.
  • Reinforce principles of safety in various settings.
  • Refer families to community resources, specialized educational facilities, and respite services; ensure understanding of legal rights available to those with disabilities.

Nursing Note Example

  • Patient: Elam, admitted for adenoidectomy on 5/7.
  • Observation: Parent present at bedside; Elam exhibits behaviors typical of autism, such as not making eye contact, rocking, flapping hands, and clinging to the parent.
  • Parenting Approach: Parent remains calm, speaking softly, maintaining close physical contact, and gently prompting with questions.
    • Elam responded positively, indicating a preference for chicken pieces and french fries for dinner after initial agitation.
  • Assessment: Vital signs taken, clinical assessment completed.

Next Gen Clinical Judgment Exercise

  • Scenario: A 4-year-old boy is preparing for an adenoidectomy. Preoperative acclimatization is the goal.
  • Priority Cues:
    1. What cues are priority when assessing this client in the preoperative phase?
    2. What cues would indicate agitation or fear?
    3. What nursing actions should be taken if these cues emerge during care?

Signs of Autism

  • Issues with communication:
    • Child doesn’t respond to name
    • Prefers solitary activities
    • Difficulty in interpreting others’ feelings
  • May exhibit repetitive movements or speech patterns.
  • Avoids or limits eye contact
  • Shows sensitivity to loud noises
  • Displays an eccentric way of moving.

Nursing Strategies

  • Consider the assessment cues associated with autism spectrum disorder.
  • Identify nursing actions that assist in addressing these cues effectively.
  • Explore methods for building a positive learning environment for children with autism spectrum disorder.
