What are stimulants commonly prescribed for?

Stimulants are commonly prescribed for conditions that involve difficulties in attention, wakefulness, or impulse control. One of the primary uses of stimulants is in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD), where they help improve focus, attention, and self-control in individuals. Additionally, stimulants can be prescribed for narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks. They can also be used as part of a treatment strategy for weight loss, as they may decrease appetite and increase metabolism.

This understanding aligns well with the nature of the disorders treated by stimulants and their mechanism of action in the central nervous system. The other options mention conditions for which stimulants are typically not first-line treatments, hence fitting the rationale of why the answer centered on ADHD, narcolepsy, and weight loss is correct.
