One of several supposed disorders a doctor may diagnose one of having. I was diagnosed with ADD, so I'm not BSing here. I was given Ritalin, which caused side effects such as appetite suppression and strange throat pain. After quitting the drug, I felt much better. I regained the weight and did not have any mental problems. Okay, so maybe I was a little hyper as a kid, but I blame it on the sugar.
I must say it is totally
wrong and apalling to pass off someone diagnosed with ADD or ADHD as a retard or idiot, they probably are smarter than you ;), and are just a victim of modern "medicine".
Doctor: He has ADHD, I prescribe Ritalin. That'll be $150.
