People often forget that...
I had terrible ADHD in childhood that was never treated, which in my adulthood changed to ADD, which I treated for a while and allowed me to get into a good school. Luckily for me, learning came easily and without too many issues due to having a rather higher IQ relative to other children. I devised my own way of learning by memorizing what was said in school and using my own reason to follow through all the implications and such at home, before I slept, just during the day. A highly inefficient way of learning, but much more effective at the actual process of learning and
understanding. Unfortunately, not everyone has the ability to reason through arguments and facts, draw the dots and see the bigger picture, and then from the bigger picture fill in the blanks. This seems to work for me in my younger years, but at college, such a method is just burdensome due to how large the picture gets.
I would say that boredom is another word that can be interchanged with ADHD/ADD. One of the primary things stimulants do is increase interest in some activity.
Anyway, here's the big problem with stimulants from a patient to the witchdoctors willing to prescribe it. The threshold where they are effective medications for people with ADHD/ADD (and even normal people, as there's a big fad nowadays with the area called 'nootropics'. Meaning enhancing performance above one's normal ability.) and where they become abusable drugs, is too slim. The temptation also is too great. Profound neurological changes occur after the administration of these drugs that persist into adulthood. Some of these changes in brain structure/wiring are thought to be positive in people with ADD/ADHD, while in normal children this can lead to an increase in hedonistic tendencies. It's really basically fucking over the future of such a child as they will be inclined to spend and not save at any opportunity. Then there's the issue of tolerance, which is actually a codeword for "I'm not feeling high anymore".
I'm an advocate for better alternatives, or at least safer and not as profound as amphetamines. Ritalin/Focalin is OK; but, again there's a lot of stuff going on behind the scenes of such children, as you pointed out. My way of resolving the issue was to simply go to one of my favorite places and learn there e.g a library and take me meds. I'm for looking into alternatives such as combining THC with CBD to cancel out the stupefying/dumbing/psychoactive effects of THC. I have found out that one can use the beneficial effects of THC on staying focused on a task and canceling out most of its psychoactive effects through combining it with CBD, a natural calming and relaxing constituent of cannabis. Given the appropriate combination, you can hit two birds with one rock. You calm the person down with the CBD constituent while increasing their level of interest/desire in some task through the increase in dopamine and norepinephrine induced by THC.
One thing has to be mentioned though. How do kids in other countries manage their ADHD/ADD without access to stmulant medications?
