Well, I do agree with him actually, to a point. I feel like Aspergers is a diagnosis like chronic pain syndrome, fibromyalgia, etc. Yes, there's stuff going on, but generally for each case, there's a different cause of where symptoms come from. That is my personal opinion about Aspergers. Like I have NVLD, for all intensive purposes, it "acts" like Aspergers, and people have said I have it, but the cause is my verbal/PIQ gap, and that's likely due to right brain disturbance. So it's not a magical mystery thing, and in my case, it's not like something I can feel super proud of, as now I know it's a flaw in my neurology that causes it, and I wonder how I'd have gotten through life without that flaw. So knowing my "Aspergers" is sorta caused by my NVLD, I wonder how other people's are caused.
And psychs can just diagnose anything. They can throw the DSM out the window and say whatever they want. IE, I wasn't supposed to be diagnosed schizoid or schizoaffective at 17 years old, but was diagnosed it anyway. The people they referred me to for treatment said that they couldn't take me for that reason, that's why I totally disregarded my diagnosis from them entirely, it took my own independent research and multiple people to convince me of the truth behind my NVLD diagnosis. Psychology is basically in the eye of the beholder, one psych will say one thing, another will say something else 180 degrees away from the other. It's a pointless "science" really. Part of the reason he's saying what he could be about Aspergers, though, is there's no medication for Aspergers, or really much treatment. So it could just be him just avoiding something he can't make money off.
And yes, I've gotten told by a psych that I have Aspergers when I argued that NVLD wasn't Aspergers.
