I am in my early 50s. The autism/Asperger's spectrum was not recognized as such when I was a child, although it definitely existed. I knew of a few other people with similar problems to my own. People on the spectrum were diagnosed as having emotional or behavioral problems, and it was felt that with the right treatment over time, that we could be cured. Pardon me a moment, while I die laughing--through my tears. I had this condition then, and still have it now. Over the years I have developed coping mechanisms for some of my problems, but I am not cured. I don't believe there is a cure. There are treatments that may help for when we are too depressed or have too much anxiety, or get too obsessive/compulsive, but there is no cure.
As for whether we are treated better now than way back when. My answer is that it is mixed. It is good that we are no longer thought of as having a curable emotional/behavior problem, as our real problems are now given some recognition, and are sometimes taken into consideration in school or at work.
Unfortunately, the general public doesn't have a very clear idea of what spectrum problems entail, and tend to think of all of us as being similar to or having the potential of, the few spectrum people who have committed horrible crimes.
In any population of people there are always going to be a few bad apples. That does not make the whole barrel rotten. Unfortunately, the general public tends to think in terms of events they have heard about, or read, or watched in the media, so we all get painted with the same brush as the spectrum people who have committed horrible crimes.
So, my answer is that society's reactions to us now are better in some ways, but not in others.
Unfortunately, not all doctors are up to date on Autism/Asperger's, so it is important to find one who is, when looking for help with it.
