The terms have been defined differently, you can use them interchangeably if it's easier but currently the medical science doesn't even have a verdict what differentiates or joins low functioning autism to high functioning to Aspergers, the symptoms are just etched out a little differently every year. And in fact most cases of autism are diverse enough that these categories are pretty arbitrary. If you have autism, you have autism. Assigning a 'level' or subcategory isn't going to change the physical nature of the condition until they can define it properly in scientific terms. (It'd be like doctors not knowing how to distinguish lung cancer from brain cancer)
But if we're sticking to these Labels, it's doubtful Chris has assbergers/High Functioning. People with it have normal to higher intelligence with some social impairments. Chris is way too far beyond that.
