History
The first reported evidence of stimulant medication used to treat children with concentration and hyperactivity problems came in 1937. Dr. Charles Bradley in Providence, Rhode Island reported that a group of children with behavioral problems improved after being treated with the stimulant Benzedrine. In 1957, the stimulant methylphenidate (Ritalin, which was first produced in 1950) became available; it remains one of the most widely prescribed medications for ADHD. Initially the drug was used to treat narcolepsy, chronic fatigue, depression, and to counter the sedating effects of other medications. The drug began to be used for ADHD in the 1960s and steadily rose in use.
In 1975, pemoline (Cylert) was approved by the U.S. FDA for use in the treatment of ADHD. While an effective agent for managing the symptoms, the development of liver failure in 14 cases over the next 27 years would result in the manufacturer withdrawing this medication from the market. New delivery systems for medications were invented in 1999 that eliminated the need for multiple doses across the day or taking medication at school. These new systems include pellets of medication coated with various time-release substances to permit medications to dissolve hourly across an 8–12 hour period (Metadate CD, Adderall XR, Focalin XR) and an osmotic pump that extrudes a liquid methylphenidate sludge across an 8–12 hour period after ingestion (Concerta).
In 2003, atomoxetine (Strattera) received the first FDA approval for a nonstimulant drug to be used specifically for ADHD. In 2007, lisdexamfetamine (Vyvanse) becomes the first prodrug to receive FDA approval for ADHD.
In 1999 the largest study of treatment for ADHD was published in the American Journal of Psychiatry. Known as the Multimodal Treatment Study of ADHD (MTA Study), it involved more than 570 children with ADHD at 6 sites in the United States and Canada randomly assigned to 4 treatment groups. All 4 treatment groups showed marked improvement from the time of baseline measurements to completion of the study 14 months later. Behavioral treatment was as effective as medication alone on 16 of 19 outcome measures. This was especially good for the behavior modification group, since the behavioral protocols were faded 3 months prior to the last evaluation and the stimulant group continued to receive medication right up to the last evaluation point.

Famous quotes containing the word history:
“When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.”
—Adrienne Rich (b. 1929)
“As History stands, it is a sort of Chinese Play, without end and without lesson.”
—Henry Brooks Adams (1838–1918)
“The true theater of history is therefore the temperate zone.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
