Neurodiversity and Neurodevelopmental Disorders

Neurodiversity

  • Neurodiversity acknowledges and appreciates that all brains function differently.
  • Emphasizes that differences don't necessarily equate to deficits or disorders.
  • Neurocognergent: Brains functioning differently from neurotypical.
  • Neurotypical: How most people's brains function.
  • Labeling is controversial due to societal response to differences rather than inherent flaws.
  • The focus should be on adjusting the environment and supporting individuals' strengths instead of forcing conformity.
  • Different perspectives are valuable for innovation and societal growth.

Affirming Principles of Neurodiversity

  • Intersectionality: Considering various identity characteristics.
  • Respecting Autonomy: Acknowledging that neurodivergent individuals can make their own decisions and take care of themselves.
  • Reframing Expectations: Adjusting societal expectations to be more inclusive.
  • Promoting Self-Advocacy: Encouraging individuals to speak up for their needs.
  • Rejecting Neurogreativity: Avoiding the notion that one brain type is superior.
  • Prioritizing Lived Experience: Valuing the experiences of neurodivergent individuals.
  • Nurturing Positive Self-Identity: Counteracting negative societal messaging.
  • Adapting Systems and Environments: Making accommodations to support different ways of functioning.
  • Honoring All Forms of Communication: Valuing diverse modes of expression.

The Importance of Perspective

  • Appreciating the differences and acknowledging how common is to be neurodivergent rather than pathologizing.

Neurodevelopmental Disorders (DSM)

  • Characterized by developmental deficits or differences in brain processes.
  • Impairments occur in various areas of functioning.
  • Focus is on brain development.

Attention-Deficit/Hyperactivity Disorder (ADHD)

Inattentive Type

  • Losing items necessary for tasks.
  • Being easily distracted by stimuli.
  • Forgetfulness in daily activities.
  • Requires at least six inattentive symptoms for diagnosis.

Hyperactive/Impulsive Type

  • Fidgeting.
  • Leaving seat when expected to stay.
  • Running or climbing inappropriately.
  • Symptoms must be present before age 12 (implying access to resources and awareness).

Combined Presentation

  • A mix of inattentive and hyperactive/impulsive symptoms.

Types of ADHD

  • Combined type.
  • Predominantly inattentive.
  • Predominantly hyperactive.
  • Diagnosis depends on the symptoms presented.

Manifestations Beyond Diagnostic Criteria

  • Impulsive behavior.
  • Difficulty concentrating.
  • Hyperactivity.
  • Fidgeting.
  • Moody and bored.
  • Emotion dysregulation.
  • Low frustration tolerance and irritability.
  • Mood swings.
  • Poor time management (potential time blindness).
  • Relationship struggles.
  • Trouble remembering.
  • Developmental delays.
  • Comorbidity: 80% comorbidity with anxiety, depression, and other mood disorders.
  • Poor sleep leading to difficulty regulating emotions.

Strengths Associated with ADHD

  • High energy and enthusiasm.
  • Humor and charisma.
  • Creativity and out-of-the-box thinking.
  • Strong verbal skills.
  • Hyperfocus on passions.
  • Problem-solving skills.
  • Empathy.
  • Brainstorming abilities.
  • Tolerance for chaos and unpredictability.
  • Loyalty and authenticity.
  • Visionary thinking.
  • Driven by passion.

Biological Considerations and Treatment for ADHD

  • Strong biological basis.
  • Medication (e.g., PET).
  • Operant conditioning.
  • Psychoeducation (for kids, parents, and adults).
  • Cognitive behavioral therapy (CBT) model.

Sociocultural Influences on ADHD

  • Disorganization in the home.
  • Parental dysfunction.
  • Low socioeconomic status.
  • Exposure to toxins.
  • Inappropriate diagnosis due to a lack of cultural competence.

Societal Mismatches

  • Expectations to focus for long periods.
  • Workplace demands.
  • Challenges with remote work pushback.
  • Girls are often underdiagnosed because diagnostic tools usually reflect boys' most common behaviors.

Autism Spectrum Disorder (ASD)

Diagnostic Criteria

  • Deficits in social communication and interaction:
    • Social interchange.
    • Nonverbal communication.
    • Relationships.
  • Restricted, repetitive behaviors or interests (at least two):
    • Stereotyped or repetitive movements (e.g., flapping, rocking).
    • Echolalia (mimicking sounds).
    • Insistence on sameness and inflexible adherence to routines.
    • Highly restricted, fixated interests.
    • Hyper- or undersensitivity to sensory input.

Social Communication Deficits

  • Abnormal social approach.
  • Difficulty with back-and-forth conversations.
  • Limited eye contact.
  • Difficulty reading facial expressions or tone.
  • Difficulties forming or maintaining relationships.
  • Difficulties showing interest in others or recognizing social norms.

Levels of Severity

  • Based on the amount of support needed.
  • Level 1: Least severe, requires less support.
  • Level 3: Most severe, requires the most support.

Alternative Model for Assessing Support Needs

  • Focuses on specific domains where support is needed rather than a general spectrum.
  • Acknowledges that individuals may need support in certain areas even if they appear to function well in others.

Strengths Associated with ASD

  • Strong attention to detail.
  • Exceptional memory.
  • Analytical thinking.
  • Strong logic and objectivity.
  • Rule-based thinking.
  • Focus and reliability.
  • Strong sense of justice.
  • Honesty and authenticity.
  • Innovative thinking.
  • Unique approaches to problems.
  • Intense passion for special interests.
  • Creative problem-solving.
  • Sense of humor.
  • Deep empathy.
  • Loyalty in relationships.
  • Nonconformity.
  • Appreciation for sensory experiences.
  • Heightened perception of nuances.

Etiology of ASD

Biological Factors

  • Strong genetic component (siblings are 15 times more likely to have it).
  • No single gene implicated.
  • Structural differences in the brain.
  • Prenatal exposure to toxins.

Debunked Theories

  • Vaccines causing autism (based on a retracted paper).

Cognitive and Behavioral Models

  • Theory of Mind: Difficulties understanding that others have different thoughts and experiences.
  • Cognitive behavioral therapy (CBT).
  • Applied behavior analysis (ABA) therapy (controversial due to past harmful practices).

Sociocultural Influences on ASD

  • Bullying.
  • Social isolation.
  • Inappropriate levels of support.

Controversial Topics and Organizations

  • Autism Speaks (criticized for fear-mongering).

Importance of Accurate Assessment and Support

  • Accurately assessing and altering conceptualizations.
  • Providing appropriate support.
  • Adapting to allow individuals to thrive.
