General Discussion

Sometimes therapy, sometimes drugs, sometimes both, sometimes neither and they figure it out themselves after learning from hard knocks or growing up?

Is the kid just a spoiled brat or has stubborn habits that will grow out of it with maybe therapy or removal from a bad environment?
Are they autistic/ADHD mix (it's an actual syndrome), are they just autistic, are they just ADHD? A schizophrenic?
Are they an actual Narcissist, budding Sociopath? Are they on a Psychotic spectrum where reality filtering is screwed up - a Narcissist, a Sociopath or a Psychopath.
Thing to remember, difference between Sociopath and Psychopath - some of the best surgeons are psychopaths; not because they want to inflict pain, but because they've come to terms with the inability to feel emotion and use that to get what they "need" - psychopaths can be encouraged/taught to be beneficial in their own way if started early.
Once they become an adult, all bets are off. Any bad habits of reaction have already become ingrained, and it's really hard to re-direct where they're heading.

I'm not a specialist in dealing with the neuro-divergent.
I've just had a lot of interaction with many over the years, some great, some tragic. Each case is different, requires different attention and reaction, and has different outcomes.
