Stimulants increase activity in the central nervous system. I am assuming that this is in regards to stimulants such as amphetamines, methylphenidates, cocaine, or other types of stimulants.

Stimulants are usually used to treat attention deficit hyperactivity disorder or ADHD. In one way or another they typically affect dopamine and to lesser extent norepinephrine. They also sometimes act on serotonin depending on the stimulant. Stimulants have been the first line of treatment against ADHD there are many controversies over stimulant medications but when taken as prescribed they can be extremely beneficial to individuals that suffer from the disorder. Stimulants used to treat ADHD generally include Adderall, Adderall XR, Dexedrine, Dexedrine Spansules, and forms of methylphenidate or Ritalin as we commonly call it.

Stimulants such as cocaine are not used to treat ADHD. Amphetamines, cocaine and methylphenidate sometimes are abused in order to get high. In one way or another this class of drugs effect dopamine the most, which is a natural reward chemical found in the CNS, norepinephrine is also another neurotransmitter and serotonin. Serotonin is typically linked to depression.

Stimulants are also used performance enhancing drugs at high schools, for the SAT/ACT and, even colleges for undergraduate, graduate, and even doctoral students. They are named "study drugs". As study drug, on what individuals to study for exams over long periods of time. It increases wakefulness and motivation thereby allowing the user to study more and also posses a more motivated mindset on the exams for confidence of their abilities.
