NR 547 Week 7 Questions with Verified Answers (Correct Update)
Question 1: Specific ADHD symptoms may arise from abnormalities within circuits in the ,
which affect .
Answer: prefrontal cortex, executive functioning
Question 2: Both selective and sustained attention are modulated by the , the same loop that is
associated with
Answer: corticostriatal-thalamocortical (CSTC) loop, anxiety
Question 3: Which NTMs are associated with inefficient information processing in the prefrontal
circuits
Answer: Norepinephrine (NE) and Dopamine (DA)
Question 4: How do non-stimulant medications work to control by selective ADHD symptoms
Answer: inhibition of presynaptic norepinephrine reuptake in the prefrontal cortex and enhancement of
norepinephrine neurotransmissioncan help lower distractibility and improve attention, working memory,
and impulsivity.
Question 5: How do stimulant medications work to control ADHD symptoms
Answer: stimulate the release of NE and DA or boost the firing of associated neurons in the prefrontal
cortex may help improve information processing
Question 6: Methylphenidate
Answer: Low risk of adverse ettects Available formulations: Ritalin: available in immediate-release (IR)
and extended-release (XR)available in beads that may be sprinkled on food for children who cannot
swallow pills Concerta: biphasic - combined immediate and delayed release in one medication Daytran:
a patch applied in the morning and removed after 9 hours
Question 7: dexmethylphenidate (Focalin)
Answer: Available in immediate release and extended release More potent than Ritalin High risk of
adverse ettects
Question 8: amphetamine (Adzenys)
Answer: It is available in an orally-disintegrating extended-release formula for children who cannot
