Like a chemical prison. Is this not the case? - No, there is no such thing at all.
[assuming appropriate diagnosis and medication by appropriate professional]
I'd be worried that it would suppress his personality and emotions, make him feel detached from reality, that kind of thing
??? But methylphenidate does nothing of this sort ! This is not at all how it works. Really, believe me and read the notice, read reputable sources on internet. This is very surprising for me. Both DC started on meds 1O years ago and at the time there was no such nonsense information floating about. If your doctor said this, he must have little experience be a charlatan or talks about a wrong medication, which is charlatanism all the same. I never heard that before.
(If they want to prescribe an antipsychotic, I don't know anything about that and I would refuse that for my DC. ADHD is not a psychosis. Methylphenidate and Strattera are meds for ADHD)
Methylphenidate makes neurotransmitters in ADHD brain to work properly, like they should in normal brain. In ADHD brain it does not has effect of a stimulant that it would have on a person without ADHD. So it is not 'drugging', nothing of this sort. And it does not modify the personality and emotions. It cannot chemically, biologically it is not what it does. It has the purpose and effect, trust me with real experience of more than 10 years, of being more able to attend to the reality, to better respond to it, to have fewer incidents which do upset and create adverse consequences. There was a thread recently in Secondary education where in the middle/end of the thread someone was telling some DC with ADHD were not officially diagnosed/medicated to prevent stigma but grew up being totally erratic, rude, failing at school, developed antisocial attitudes and did become failures in many ways. For me it was an example of parental discriminatory prejudices ruining DC' future by denying the diagnosis and appropriate medication. The real risks and consequences are in not giving medication. ADHD does create problems. Medication mitigates them.
However, my DS also has ASD in addition to ADHD. When we started on meds, DS's atypical reaction to people, interactions and the whole autistic symptoms became apparent, which was news to teachers and to us. Some of them felt he was looking a little aloof, 'zomby' like compared to his hyperactive self. But that was his autism showing up, becoming apparent without being hidden by hyperactivity. It was not him 'having suppressed emotions and being detached from reality'. It was his autism idiosyncrasies, symptoms. The doctors told us this would happen, this is how it enabled to officially diagnose ASD, because without meds the picture was muddled.
Again, with long term and extensive experience of ADHD and methylphenidate, I assure you, it mitigates symptoms, enables to do what DC are capable of, enables to function closer to their potential, but takes nothing away it terms of personality and control. Trust me.
