> The way I describe it to most people is very simple. If you give a ADD/ADHD child Ritalin, Adderol, etc, they will calm down. You give those drugs to a normal child and they get super hyperactive. No they don't, ~25% won't feel anything. Most will become more focused. Methylphenidate and Methamphetamine /sound/ the same, but the former is better at "stimulating" certain brain structures : ) > Inversely, you give most people a stimulant such as caffeine and their heart beat increases and they perk up. I've always been very careful about coffee in the morning or teas as it is very much a calming downer. Sometimes I will drink a coffee to really calm my (always thinking too much) brain and let me focus, but can't do it if I'm the least bit tired as I'll be more inclined to doze off mid day. Yeah, the "ADHD people react oppositely to stimulants" stuff is folklore. Go drink a quad shot latte and tell me caffeine actually makes you tired. > I'm happy to see more actual science that shows this is a real thing, not something made up by an impatient child or child who had lots of trouble paying attention in school. Brain scans are fun, but cognitive psychology is where the real work gets done: https://www.youtube.com/watch?v=NUQu-OPrzUc https://www.youtube.com/watch?v=NUQu-OPrzUc
