Question

which of the following are the effects of central nervous system stimulants, such as ritalin, on children with attention - deficit/hyperactivity disorder (adhd)? correct answer(s) they work by reducing activity in the brain’s frontal lobes. they make children happier and more socially adept. they dramatically improve academic performance. they cause a small decrease in positive behaviors and a small increase in negative behaviors. they decrease distractibility and overactivity. they increase attention and ability to concentrate. incorrect answer(s)

Explanation:

To determine the correct effects of CNS stimulants (like Ritalin) on ADHD children:

• Correct effects: Stimulants increase dopamine/norepinephrine, enhancing focus (increase attention/concentration) and reducing hyperactivity/distractibility. They don’t “dramatically” improve academics (modest gains), nor do they reduce frontal lobe activity (they enhance it) or cause negative behavior increases. Social adeptness/happiness isn’t a direct effect.
• Thus, the correct options are:
• They decrease distractibility and overactivity.
• They increase attention and ability to concentrate.

Answer:

• They decrease distractibility and overactivity.
• They increase attention and ability to concentrate.
