true
syms of ahdh persist into adulthood in about what percent of cases
50%
Hypothesis: children with adhd are neurologically immature, dvp slower explains what finding?
syms decrease with age
dopamine and norepinephrine (catecholamine neurotransmitters) appear to function __ in ppl with ahdh
abnormally
siblings of children with adhd are # to # times more likely to dvp it than siblings without it
3 to 4 times
twin studies and adoption studies suggest genetic factors play a role in vulnerability to adhd
true
many children with adhd have a history of __ and __ complications (low birth weight, premature delivery, oxygen depreivation)
prenatal and birth complications
kids with adhd are more likely to belong to fams with parents prone to aggressive, hostile behaviour and substance abuse
true
what interaction pattern influences the course and severity of adhd, including the dvp of conduct problems
family
most children with adhd are treated with ___, they work by increasing levels of dopamine in the synapses, enhancing release and inhibiting reuptake of dopamine
stimulant drugs
adhd stimulant drugs show a __ in growth rate
decrease
drugs that are not stimulants but also treat adhd by affecting norepinephrine levels
atomoxetine, clonidine, guanfacine
___ therapies for ADHD focus on reinforcing attentive, goal-oriented, and prosocial behaviours and extinguish impulsive and hyperactive behaviours
behavioural
What disorder does the following DSM-5 criteria belong to:
- persistent deficits in social communication and social interaction across multiple contexts
- restricted, repetitive patterns of behaviour, interests, or activities
- syms must be present in early dvp period
- syms cause clinically significant impairment in social, occupational, or other important areas of current functioning
- disturbances not better explained by intellectual disability or global dvp delay
autism spectrum disorder
deficits in social interactions and communications of autism may first show up in infants and toddlers interactions with __ by reciprocal adoration
their parents
True or false: approx. 50% of children with ASD do not dvp useful speech
true
echolalia
rather than generating own words, echo words of others
rather than being interested in symbolic play, kids with ASD __
are preoccupied with one feature of a toy or object
self-stimulatory behaviour
behaviours by ASD for self stimulation
children with autism often do ___ on measures of intellectual ability
poorly
family and twin studies strongly suggest that genetics plays a role in the dvp of ASD, the siblings of children with ASD are __ times more likely to have the disorder
50 times
twin studies show concordance rates for ASD to be % for monozygotic twins and 0-% for dizygotic, about 90% of MZ twins have significant cognitive impairment, about 10% for DZ
60%, 30%
Approx. __% of ASD children dvp seizure disorders by adolescence and have greater head and brain size in general
30%
ASD has structural abnormalities in the following structures
cerebellum, cerebrum, amygdala, hippocampus
children with autism have __ than average rates of prenatal and birth complications
higher
ASD: selective serotonin reuptake inhibitors appear to reduce __ behaviour and __, improving social interactions in some
repetitive, aggression
atypical antipsychotic medications have shown __ reliable effectiveness
more
stimulants are used in ASD to improve __
attention
operant conditioning strategies are used to reduce excessive behaviours and to alleviate deficits
true
Intellectual disability (ID)
significant deficits ion intellectual abilities and life functioning
ID onsets during
the dvp period
What disorder does the following DSM-5 criteria belong to:
- deficits in intellectual functions confirmed by clinical and standardized testing
- deficits in adaptive functioning that results in failure to meet dvp and sociocultural standards for personal indp and social responsibility
- onset of intellectual and adaptive deficits during dvp period
ID
What disorder is classified into four levels of severity: mild, moderate, severe, and profound
ID
what level of severity of ID does this describe:
some limitations in ability to acquire typical academic or job-related skills, may seem immature in social interactions, overly concrete in their communications with others, show limited social judgment and understanding of risk, may be able to care for themselves reasonably well outside of complex situations
mild level
what level of severity of ID does this describe:
significant delays in language development, physically clumsy, typically do not achieve beyond 2nd grade level in academic skills but in special education can acquire simple vocational skills, may hold jobs requiring only elementary school level skills, will need assistance, can care for their needs with extensive training, may show poor social judgment
moderate level
what level of severity of ID does this describe:
very limited vocabulary, may speak in two/three word sentences, as children have sig deficits in motor dvp, play with toys inappropriately, can feed themselves with spoon as adults and dress themselves with easy clothing, cannot travel, cook, shop alone, many unable to learn unskilled labour, lack awareness of risk
severe level
what level of severity of ID does this describe:
often do not dvp conceptual skills beyond simple matching of concrete physical features of objects, co-occurring sensory and motor impairments prevent functional use of objects and limit participation in everyday activities to watching, may only be able to understand simple concrete instructions and gestures in social domains, fully dep on others
profound level
Individuals with ID usually have __ SD below the mean in IQ
2
nearly __ genes affecting brain dvp and functioning have been implicated in ID syms
300
what are the two metabolic disorders that are genetically transmitted and cause ID
PKU (phenylketonuria) and Tay-Sachs disease
how does PKU cause ID (recessive gene)
indvs with PKU are unable to metabolize phenylalanine (amino acid) which builds up and causes brain damage, can be avoided with a diet free of phenylalanine
how does Tay-Sachs cause ID (recessive gene) and what population is it prominent in
prominent in Jewish peeps
around 3-6 months old a progressive degeneration of nervous system begins, leading to mental and physical deterioration, usually die before age 6, no treatment

ID
Many indvs with down syndrome have congenital heart defects and gastrointestinal difficulties, as adults they age more __ than normal, shortening their life span
rapidly
Fragile X syndrome is another common cause of __
ID
what causes fragile x syndrome
when the tip of the x chromosome breaks off, affects primarily males
