In the past, Asperger’s Syndrome and autism were thought to be two entirely different things. People with autism were not able to live in society because of their mental disabilities and physical problems; while people with Asperger’s may have a difficult time relating to society and the people in it, they were still able to function and have relatively “normal” lives. This has recently changed. Now Asperger’s is classified as high-functioning autism. So, as of a few years ago there is no difference between the two. Some people who are considered high functioning autistics do not have all the features of autism though.
