However, I have heard people claim that Ritalin is overprescribed because "ADHD doesn't exist." These people are flat out wrong. Most mental illnesses and neurological disorders aren't specific things that you can point to, but rather, they're a collection of symptoms that we group together. If someone is diagnosed with ADHD, it's because they exhibit a cluster of behaviors that are classified under a common label.
Now, the issue with judging if something is overprescribed is how to decide if it actually provides a benefit. Everyone who has even a moderate form of any of the symptoms of ADHD would benefit from pharmaceuticals, but would those advantages outweighs
