I have ADD myself, and I actually was, at one point, diagnosed with ADHD.
I find the idea of ADHD (and the whole phenomenon of the mass distribution and prescription of designer drugs to be given to young children) to be rather sketchy, mainly because of the type of evidence that ADHD is based upon, and the seemingly dangerous amount of power that popular stimulants like Adderall and Ritalin possess and enact upon very young children, who all are being given this medication in droves, simply, in some cases, upon a parent just walking into a doctor's office and saying that their child possesses some difficulty paying attention in class. I often find myself agreeing with the notions that is often claimed by many psychologists that ADHD is not only being over-diagnosed to a mass extent, but also that the concept of ADHD and evidence behind ADHD actually being a real disorder is questionable at best, and that this could very well be a case of pharmaceutical companies exploiting the system as to make a large sum of monetary assets as a result of the overt amount of diagnoses for ADHD, and the relation that has to the ability of the said companies being able to sell their drugs.
