As far as I understand it, Asperger's is the result of a significant difference in brain structure compared with those of NTs.
If by 'cure' we mean a treatment that will change the brain structure of an aspie to that of an NT in a non-destructive way, I don't think there will be such a cure.
To the extent that AS is the result of a genetic propensity that might be activated by environmental conditions, one could perhaps hope to examine a recently fertilized egg for genetic markers, apply genetic engineering to the small collection of cells, and aim at avoiding environmental triggers. This is the only direction that I could see a 'cure' taking - something that would have to be applied shortly after conception, that only has a chance of working, and that could not be applied much later.
There will be no magic pill.
I am very much in favor of seeking treatments to allieve or reduce the problems that AS can cause many people, but I would not want to reduce its benefits.
For me, AS is very much a mixed bag - some good, some bad. If I had understood when I was young what was going on, why I was different, how I could cope, and that I wasn't alone, so much would have been different, better.
I would not want a 'cure' for myself - so much of my creativity arises from AS, if I am not mistaken.
So - yes on research for treatment, no on research for a cure, yes on education and acceptance, no on the 'pursue a cure or you are a traitor' nuts.
