Autism Spectrum Disorder is a developmental disability that can cause ———–, ————-, and ——– challenges.
social, communication, behavioral
3.21.24-Neuropsychiatric Disorders
In order to be diagnosed with Autism Spectrum Disorder, a person must:
- have ————– deficits in social communication and social interaction that present ————–.
- have ———— and ———— patterns of behavior, interests, or activities
persistent; multiple contexts
restrictive; repetitive
According to the DSM-V, a person with ASD has:
- challenges in social-emotional ————
- deficits in —————— behaviors used for social interaction
- deficits in ————-, ————–, and ————- relationships.
- reciprocity
- nonverbal communicative
- developing; maintaining; understanding
A person with ASD has restrictive, repetitive patterns of behavior, interests, or activities manifested by at least 2 of 4 things:
- stereotyped or repetitive motor movements, use of objects or speech
- insistence on sameness, inflexible adherence to routines, or ritualized patterns of behavior (verbal or nonverbal)
- highly restricted, fixed interests taht are abnormal in intensity or focus
- hyper or hyporeactivity to sensory input or unusual interest in sensory aspects of the environment
In Autism Spectrum Disorder, symptoms must be present in ————————- (but may not ————).
early developmental period; become fully manifested until later
T/F
People with ASD must have an intellectual impairment in order to be diagnosed.
False; ASD can be with or without accompanying intellectual impariment
T/F
A language impairment is not a requirement in order to be diagnosed with ASD.
True
According to the DSM, how many/what are the severity levels of ASD?
3 levels
Level 1: requiring support (speaks but lacks reciprocity; difficulty switching activities)
Level 2: requiring substantial support (simple/limited sentences, distress when changing focus)
Level 3: requiring very substantial support (non-verbal; great distress when changing focus.
To be diagnosed with ASD, the individual’s disturbances are not better explained by ————— or —————–.
- intellectual disability
- global developmental delay
For people with ASD, symptoms cause —————– in social, occupational, or other important areas of current functioning.
significant impairment
add some flashcards that make you figure out which disorder
According to the CDC ——- of 1000 (or 1 in ——) 8-year-olds has ASD.
18.5; 54
Boys are how many times more likely to be diagnosed than girls with ASD.
4x
Boys = 1/34
Girls = 1/45
Why are girls (potentially) underdiagnosed with ASD?
2 reasons
- different symptom presentation (less restrictive/repetitive behaviors)
- better as masking social aspects
Which group of children is least likely to be diagnosed with ASD?
- black
- Asian/Pacific Islander
- white
- Hispanic
Hispanic (1/60)
ASD is strongly ———- and there is evidence supporting it as a ———- disorder.
heritable; biological
Explain how brain growth in children with ASD seems to differ from children without the disorder.
Children with ASD seem to have overgrowth of the brain between ages 2-4.
Overgrowth ends around 5-6 then stops (no significant enlargement after this point)
Later in adolescence/childhood, there seems to be a decline in gray matter volume.
————– is not observed in all people with ASD. What are some reasons this might be?
Brain overgrowth
- not a common pathological mechanism?
- neurobiological subtype with larger brain?
- pattern of general physical overgrowth?
People with ASD seem to have ————- overgrowth, including the ———— of typical growth patterns.
unequal; reverse (brain grows front to back instead of back to front)
Unequal overgrowth in children with ASD leads to ————- of prematurely developing regions from the rest of the cortex, which causes ———————–.
uncoupling; differences in connectivity
During which developmental processes does overgrowth in people with ASD occur? What other effect does this have?
3 processes for question 1
synaptogenesis, myelination, pruning
effects white matter: high white matter integrity early on, but then lower integrity later
In adults with ASD, we see abnormalities in which brain structures?
7 regions
- fronto-temporal
- fronto-parietal
- amygdala-hippocampal complex
- cerebellum
- basal ganglia
- anterior and posterior cingulate regions
T/F
Symptoms of ASD must be persistent and found in multiple domains to warrant a diagnosis.
True
T/F
ASD is characterized by an overgrowth of the brain in early years.
True
