What is the difference between HFA and Asperger's?

I'm going to be honest, I'm not sure how this plays out with the newest DSM books taking Asperger's away as a diagnosis. It used to be that you had an autism spectrum which went from Asperger's to high functioning autism to classic autism. The HFA kiddos sometimes had their diagnosis changed to Asperger's after lots of therapy and basic maturity. The main thing that was looked at was socialization and verbalization which doesn't seem to be such a golden standard anymore. All children on the spectrum at this point are said to simply said to have ASD (autism spectrum disorder). I choose to still identify Bub as an aspie because that's the most accurate descriptor for his specific situation.

    I'm not even sure what DSM or HFA means. I've heard of Asperger's, autism and there's another one too with a boy's name but I cannot remember. So I am a bit clueless on this topic.
