Exam 2 Flashcards
how many symptoms in the categories of inattention and/or hyperactivity/impulsivity are needed to be diagnosed with ADHD
six
what are the 3 characteristics necessary for one to be considered in inattention and hyperactivity
- greater than 6 months
- inappropriate for developmental level
- maladaptive
what are the changes to ADHD from the DSM-4 to the DSM-5
onset age went from 7 to 12
ppl 17+ people only need 5 symptoms
moved from subtypes to specifiers
what are the three ADHD specifiers
can they all be unreliable over time?
combined
predominantly hyperactive-impulsive
predominantly inattentive
yes
Which specifier is described:
more common in younger children
behavior problems
likely to be diagnosed with combined later
predominantly hyperactive-impulsive
Which specifier is described: common learning disabilities lower academic achievement diagnosed in school age sluggish cognitive tempo
predominantly inattentive
Which specifier could be seen as a separate diagnosis than ADHD
predominantly inattentive
what is the importance of specifiers over subtypes
represent how the child is in the present and can be unreliable and change over time
the combined specifier and predominantly hyperactive-impulsive specifier may not be distinct meaning it could be the same kid but at a different age
TRUE
is ADHD stable?
yes
why do 25-30% of kids not meet criteria for ADHD during adolescence
they learn to manage symptoms
what are the three associated features of ADHD
- ODD and CD
- less compliant kids and hostile parents
- disliked by peers
considered to be pleasure pathway
involved in the behavioral activation & behavioral inhibition system
mesolimbic neural circuit
- responds to signals of reward & nonpunishment
- more active in ADHD
behavioral activation system
- responds to signals of nonreward & punishment
- produce anxiety at fear stimuli
- less active in ADHD
behavioral inhibition system
what two structures are implicated in the frontal-striatal neural circuit & are linked to ADHD and why
prefrontal cortex; reduced volume and thickness
striatum; delayed growth in caudate w/ less synaptic pruning, rich in dopamine
why is the frontal-striatal neural circuit important
- regulates behavior based on feedback
- executive functioning
based on Barkley’s neurodevelopmental model, what issues are at the heart of ADHD
behavioral inhibition
what three categories do people with ADHD struggle with
- internalized speech
- emotion regulation
- creative problem solving
What is this a problem in:
(ADHD) more dependent on environment & others to regulate
won’t talk to themselves to regulate behavior
internalized speech
What is this a problem in:
(ADHD) focused on immediate rewards; less willing to suffer through frustrations
emotional regulation
What is this a problem in:
(ADHD) difficulties in organizing, planning, & generating strategies
creative problem solving
work by increasing dopamine activity in frontal striatal circuit
improve attention & reduce impulsivity
psychostimulants
does not impact dopamine
effective but lower reduction rates
ex: selective norepinephrine reuptake inhibitor
do not show improvement in inattention or impulsivity
non-stimulant medications
