Final answer:
Stimulant medications are commonly used to treat ADHD, aiding in improving focus and reducing impulsivity despite their name suggesting increased activity.
Step-by-step explanation:
The question pertains to the type of medication used to treat patients with ADHD. The correct answer is c) Stimulant medications. Stimulant drugs, such as amphetamines, have a paradoxical calming effect on individuals with ADHD, and increase neurotransmitter activity in brain regions linked to impulse control, such as the prefrontal cortex and basal ganglia. While it may seem counterintuitive, stimulants help manage ADHD by enhancing concentration and reducing hyperactive and impulsive behavior.
