Many people think of rowdy kids who can’t sit still when they think of ADHD. But many adults continue to struggle with symptoms of ADHD. Lots of adults with ADHD don’t realize that many of the problems they face, including staying organized or being on time, are symptoms of adult ADHD.
These drugs improve ADHD symptoms in about 70% of adults and 70% to 80% of children. They tend to reduce interruptive behavior, fidgeting, and other hyperactive symptoms, as well as help a person finish tasks and improve his or her relationships.
Improvements in behavior and attention span usually continue as long as the medication is taken, although benefits in social adjustment and school performance have not yet been shown to endure over the long term.
Stimulants are not considered to be habit-forming in the doses used to treat ADHD in children and adolescents, and there is no evidence that their use leads to drug abuse. Nonetheless, there is a potential for abuse and addiction with any stimulant medication, especially if a person has a history of substance abuse and addiction.

There are many stimulants available to treat ADHD: short acting (immediate-release), intermediate-acting, and long-acting forms. Common stimulants include:
The short-acting forms of the drug are usually taken two or three times a day and the long-acting ones just once a day.
Newer forms of some stimulant drugs may reduce side effects and relieve symptoms for a longer period of time. They include Concerta (10-12 hour duration), Daytrana patch (7- 10 hours, depending on how long it is worn), Ritalin LA (6-8 hours), Metadate CD (6-8 hours), and Adderall XR (10-12 hours).
