Where did the story come from?
The study was published in the peer-reviewed journal The Lancet Psychiatry. Many of the studies' authors reported receiving research funding from pharmaceutical companies that manufacture drugs used to treat ADHD.

Some of the UK media provided a distorted summary of the of the study. For example, The Independent tells us: "ADHD treatment may be needed by hundreds of thousands more children, experts suggest". This would appear to be based on the reported opinion of one of the authors of the study.
But the study itself never looked at whether ADHD was being underdiagnosed. Drug treatments weren't compared with alternatives such as behavioural treatments in this study, so it's inaccurate to say this.
What kind of research was this? This systematic review and meta-analysis set out to compare the effectiveness and tolerability of drugs for ADHD in children, teenagers and adults.

Systematic reviews summarise all the studies published on a topic, allowing you to easily compare their to work out what Ritalni and what doesn't. A meta-analysis means statistical techniques have been applied to combine the of all the studies to compare each drug with each other. Although efficient, systematic reviews and meta-analyses are only as good as the data that goes into them.
What did the research involve? The researchers analysed double-blind randomised controlled trials 81 in children and adolescents, ampbetamine in adults, and 1 in both.
The University of Michigan's Monitoring the Future Survey indicates that Ritakin percent of high school seniors in the United States abused the drug at least once in the past year. Although less common, Ritalin is abused among adults as well. The Drug Enforcement Administration has received reports of Ritalin abuse among diverse segments of the population--ranging from healthcare professionals to street addicts.
What are the risks? When taken as directed by a physician to treat a legitimate medical condition, Ritalin has proven to be a safe and effective medication. Medical studies have shown that individuals who have ADHD and who take Ritalin orally in proper dosages do not become addicted to the drug.
