Those medicines made them feel worse--they were not abusing their drugs. Ritalin is another drug that causes these problems.
Depends on the person. I eventually found this time around that Ritalin did depress me after awhile, I later learned why - it was stimulating my Peripheral Nervous System (as opposed to my Central Nervous System) which over time depletes your endocrine system if you are one that already has an overactive limbic system. However, other people with ADHD respond very well to it. When I switched to Dexedrine, I found the same results some get from Ritalin but not Dexedrine. Everyone is unique. Dexedrine is only a CNS, not PNS stimulant.
Why are such drugs necessary in the first place? Because the school boards wish to dumb down the people. In doing so, they need to stifle children's drive to learn. To do that, they diagnose a disease that, in essence, is the normal drive for them to learn and integrate. Then they prescribe a drug to treat that disease. That drug also sets up these children to become more violent than they otherwise would have been. In some cases, the parents were forced by the state to give these children these drugs.
No, it's not to dumb people down. It is to make sure that they have an equal chance to succeed in the public school system without there needing to be sent to special learning environments...which could be better for them perhaps but where is the capital? My mother wasn't "forced" per se to put me on Ritalin, but I would have had to be home schooled (which may have been better).
I suggest doing away with that "ADD" and "ADHD". Children need to be active. The ones that are actually more active than normal, in a proper school environment, can and will actually do better than those who are naturally more docile. With their drive to learn satisfied (and, with the most active children, this can be much more than most classes are set up to handle), they are not as likely to get into trouble, and will not need those drugs. No drugs, no violence. And that will solve something like 90% of these incidents.
Your ignorance shines through here, and you must not have had a close relationship with anyone that truly has the symptomology. Children with ADHD are not just simply hyperactive kids, because obviously then I would agree with you. The development of impulse control and the lack of ability to concentrate on what you want your mind to rather than it going where it wants to every few seconds tends to impeed progress in classically structured learning environments. Many with ADHD also have Auditory Processing Disorders (I among them) whereby they don't catch all the words in a sentence when being spoken to, and have to fill in the gaps and process the information, if your mind is wondering (not of your own choice) this is made even harder. To tell if someone was misdaignosed (or grew out of it, which 40% sometimes do), you will see the hyperactivity disappear. What you will see if the diagnoses is correct is the hyperactivity in adolescence transforms into an inner restlessness, a compulsion for stimulation (which may include stimming if autism is present), and constant fidgetting or inability to wait in line. These are the people that appear driven by a motor, and feel more comfortable if their body is in motion somehow. (Of course ADHD Predominately Inattentive (formerly ADD, term not in use anymore) lack the hyperactivity/impulsivity factor of the symptomology.)
People are only ever taught about the three main "bad" aspects of this label, but fail to realise the difference in brain structure and chemistry (not chemical imbalance, chemical dysfunction, big difference) lead to a complex interconnected realm of "symptoms" but many are very positive.
The idea that ADHD is a lack of discipline is pretty funny. If you were to hold a gun to someone's head with ADHD and told them if they moved their head at all or become distracted you will blow their head off, you'll probably be doing it within 20 seconds. They will forget that instruction within a few seconds and their mind will start racing with other thoughts. You'd probably have to remind them every 10 seconds or so about that instruction or they'd be dead. Telling someone with an inability to focus their thoughts for a long period of time (effort is but one factor in concentration, learn some neuroscience...) to "try harder" is like telling someone who is nearsighted to "squint harder", it is a disability in the truest sense of the word, and is recognised as such by governments.
When I took Dexedrine for the first time, it was like that nearsighted person putting on those glasses. It does not make me dumb, this is ridiculous. In fact, the only reason I had the patience to type this entire response to your post was because I'm medicated right now. I don't know, does it sound like I'm dumb?
