Asperger syndrome

Asperger syndrome is one of several autism spectrum disorders (ASD) characterized by difficulties in social interaction and by restricted, stereotyped interests and activities.
There is no single treatment for Asperger syndrome, and the effectiveness of particular interventions is supported by only limited data. Intervention is aimed at improving symptoms and function. The mainstay of treatment is behavioral therapy, focusing on specific deficits to address poor communication skills, obsessive or repetitive routines, and clumsiness. Most individuals with AS can learn to cope with their differences, but may continue to need moral support and encouragement to maintain an independent life. Researchers and people with AS have contributed to a shift in attitudes away from the notion that AS is a deviation from the norm that must be treated or cured, and towards the view that AS is a difference rather than a disability.

I heard that most of autism spectrum disoerders has no cures. However, some cases like Temple Grandin, who worte "Animals in Translations", can be unleashed from there. If her level of autism was low as much as can be cure, I'm just wondering what the level of boundary is.
