*Autism Spectrum Disorder - DSM

Autism Spectrum Disorder (ASD) - DSM Criteria

A. Persistent Deficits in Social Communication and Social Interaction

  • Presentation: Pertains to multiple contexts, can be current or historical.

  • Components:
      - Deficits in Social-Emotional Reciprocity:
        - Ranges from abnormal social approach and failure of typical back-and-forth conversation.
        - Examples include reduced sharing of interests, emotions, or affect.
        - Includes failures to initiate or respond appropriately to social interactions.
      - Deficits in Nonverbal Communicative Behaviors for Social Interaction:
        - Ranges from poorly integrated verbal and nonverbal communication.
        - Includes abnormalities in eye contact and body language, deficits in understanding and using gestures.
        - May lead to a total lack of facial expressions or nonverbal communication.
      - Deficits in Developing, Maintaining, and Understanding Relationships:
        - Involves difficulties adjusting behavior according to various social contexts.
        - Includes challenges in sharing imaginative play or making friends.
        - Often characterized by a lack of interest in peers.

B. Restrictive and Repetitive Patterns of Behavior, Interests, or Activities

  • Manifestation: Must include at least 2 of the following:
      - Stereotyped or repetitive motor movements, use of objects, or speech.
      - Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behavior.
      - Highly restricted, fixated interests that are abnormal in intensity or focus.
      - Hyperactivity or hyporesponsiveness to sensory input, or unusual interests in sensory aspects of the environment.

Additional Criteria for Diagnosis

  • C. Symptoms Must Be Present in Early Developmental Period

  • D. Symptoms Cause Clinically Significant Impairment
      - Impairment must affect social, occupational, or other important areas of functioning.

  • E. Not Better Explained by an Intellectual Disability

Clinical Description of ASD Levels (Recognized by DSM)

  1. Level 1: Requiring Support
       - Problems with inflexibility, poor organization, planning, and switching activities impair independence.
       - Poor social skills, difficulty in initiating interactions, often making odd and unsuccessful attempts to befriend others.

  2. Level 2: Requiring Substantial Support
       - Marked difficulties in verbal and nonverbal social communication skills.
       - Noticeable difficulties with changing activities or focus. Markedly restricted repetitive behaviors.

  3. Level 3: Requiring Very Substantial Support
       - Severe difficulties in verbal and nonverbal communication.
       - Very limited speech; many individuals express basic needs only through odd, repetitive behaviors.

Key Statistics and Notes

  • Understanding of how brain networks function in individuals with ASD is crucial. Research indicates important differences in brain connectivity in children diagnosed with the disorder.

Conclusion

  • Autism Spectrum Disorder is characterized by a broad range of symptoms affecting communication, social interaction, and behavior. The level of support required varies greatly among individuals.
