Over diagnosis
Although plenty of kids have ADHD and need medication for it, a lot of the time perfectly normal kids are diagnosed. This is due to a lot of advertising and presentations given to doctors that overstate the risks of ADHD and the benefits of taking ADHD medication like Adderall and Ritalin; while downplaying the risks of taking these medications. If someone pressures you to get yourself or your kid medication for this disorder, remember that it's up to you and you don't have to get it.
