Q

What was the shifting paradigm for Neurodiversity?

A

Neurodiversity: Natural variation in human neurocognitive function

Leads to

Neurodiversity Paradigm: No one type of brain function is “right” or “best.” Ideal neurocognitive function is socially constructed. Neurodiversity is subject to power inequities, but also a source of creativity and empowerment.

Leads to Neurodiversity Movement: Social movement that seeks civil rights, equality and inclusion for everyone, regardless of neurocogntive function.

Q

Autism Criteria A

A

Persistent deficits in social communication and social interaction across multiple contexts: Must have all

1) Deficits in socio-emotional reciprocity ranging from abnormal social approach and failure of normal back-and-forth conversation.

2) Deficits in nonverbal communicative behaviors used for social interaction, such as poorly integrated verbal and nonverbal communication; to abnormalities in eye contact and body language or deficits in understanding and use of gestures; total lack of facial expressions.

  1. Deficits in developing, maintaining, and understanding relationships, ranging from difficulties adjusting behavior to suit various social contexts.

Q

Autism Severity Level 3

A

Requiring very substantial support:

Social Communication: Severe deficits in verbal and nonverbal social communication skills cause severe impairments in functioning. Minimal response to social overtures.

RRBs: Inflexibility of behavior, extreme difficulty coping with change, other RRBs interfere with functioning

Q

Autism Severity Level 2

A

Requiring substantial support

Social Communication: Severe deficits in verbal and nonverbal social communication skills, which cause severe impairments in functioning, very limited initiation of social interactions, and minimal response.

RRBs: Inflexibility of behavior, difficulty coping with change, or other RRBs appear frequent enough to be obvious to the casual observer and interfere with functioning in a variety of contexts.

Q

Autism Severity Level 1

A

Requiring Support

Social Communication: W/O supports are in place, but deficits in social communication cause noticeable impairments. Difficulty initiating social interactions.Unsuccessful response to social overtures of others. May appear to have decreased interests in social interactions.

RRBs: Inflexibility of behavior causes significant interference with functioning in one or more contexts.

Q

Executive Functioning (ASD)

A

Hyper focus, demand avoidance, hygiene, process complexity, Difficulty changing tasks

18
Q

Autism Spectrum: SPINS

A

SPecial INterests, intense research, information hunger collections

19
Q

Autism Spectrum: Stims

A

Energy regulation, sensory seeking, repetitive movements

20
Q

Autism Spectrum: Exteroception

A

Sensing the outside world, hypersensitive or hypnosensitive

21
Q

Matt Lowry (2023) Strengths-Based Diagnosis: A-Different social communication evidenced by

A

1: Difference in communication, tendency to go off on tangents, tendency to talk about special interests.

2: Differences in nonverbal communication. This includes stimming while talking, looking at more interesting things while talking, being bored in conversation and would rather be doing something else.

3: Autistic people tend to be shunned due to differences in communication from neurotypical people. This makes autistic people conditioned to believe that they’re somehow less social (think opposite when at comic con).

22
Q

Matt Lowry (2023) Strengths-Based Diagnosis: B- RRBs evidenced by at least two of the following

A

1: Stimming or engaging in echolalia

2: Security in routines: Autistic people do not have a sensory filter, so the world is perceived in a state of chaos

3: SPecial INterests (SPINS) Due to hyperconnected brains, autistic people feel more passionately about what they love.

4: Hyper-Hyporeactivity to stimuli- feeling things more intensely. Monotropism: feeling things less intensely because we tune them out in favor of other stimuli (example: we might go outside without a coat, because we are so focused on the mission at hand)

23
Q

Matt Lowry (2023) Strengths-Based Diagnosis: C

A

We’re born with these traits, but we learn how to mask them. Can show up when we’re stressed out

24
Q

Matt Lowry (2023) Strengths-Based Diagnosis: D

A

These traits cause other people distress (DSM only considers this when it affects aspects of living, NOT when it’s a daily issue).

25
Matt Lowry (2023) Strengths-Based Diagnosis: E
Not due to an intellectual disability. Autistic people might do poorly on an IQ test; however, factors like performance or test anxiety, along with lack of experience dealing with autism from the examiner, might indicate lower IQ than actual.
26
Core Challenges in ASD
-Social Communication -Social Imitation -Face perception -Joint attention -Communication abilities -Social attention -RRBs
27
Social Emotional Competence
Awareness of own emotional state Awareness of other's emotional state Emotional use of words Ability to cope with emotional distress
28
What happens when a child with ASD looks into another's eyes (Ramachandran)
- The altered connection between the cortex and amygdale distorts the childs response -The amygdale triggers the autonomous nervous system, raising their heart rate -Child looks away to reduce stress
29
Theory of Mind (ASD)
Capacity to imagine or form opinions about the cognitive states of other people
30
What brings parents into seeking treatment (ASD)
Language and communication -50% remain mute throughout lifespan -85% have echolalia
31
What are two underlying factors of ASD
Instance on sameness (IS) Repetitive sensory, and motor behaviors (RSMB)
32
What are comorbid challenges with ASD
Anxiety Sleep disturbances Eating disturbances -Health Conditions -Fears and response to sensory stimuli -31% have an intellectual disability
33
Differential Diagnosis for ASD
-Language disorders -Childhood-onset schizophrenia - PTSD -Other neurodevelopment disorders
34
Three different patterns of autism
1: Congenital group- atypical behaviors are present from birth. 2: Failure to develop skills: early milestones followed, but development plateaus 3: Period of norma; development, followed by regression and loss of previous skills
35
Model for Etiological Indicators (ASD)
1) Genetic markers 2) Neuroanatomical abnormalities 3) Information processing impairments 4) Manifestation of behavioral symptoms
36
Etiology: Genetic Factors (ASD)
-Twin studies -The broader autism Phenotype -ASD susceptibility genes
37
Etiology: Environmental Risk Factors (ASD)
-Prenatal and Perinatal risk factors -Season of birth -Maternal and paternal age -Environmental toxins -Gene-environment interactions
38
Genetics and Heritability for ASD
ASD and twins = 38% Heritability coefficients between 64% and 91% Shared environmental effects = 7% to 35% Sibling recurrence 19% Subthreshold symptoms = 4-20%
39
Neuroanatomical findings for ASD
-Atypical brain growth and volume -Limbic system-reduced neuronal cell size -Corpus Callosum (reduced size) -Cerebellum decreased -Prefrontal cortex- decreased functioning -Brain connectivity problems
40
Biochemical Markers for ASD
25-50% have very high levels of serotonin -Unusual patterns of dopamine, norepinephrine and endogenous opioids
41
Controversy with ASD
Immunizations Gastro/leaky gut Heavy Metals
42
Prenatal Factors (ASD)
- Mothers older than 35-50 years -Fathers older than 50-55 -Uterine bleeding -Low birth weight
