Please tell me what's the difference between autism and aspergers?

Autism spectrum: Autistic disorders, like many, if not most, other diseases and disorders, exist on a spectrum from milder to more severe. Asperger's disorder is a way of describing someone in the "higher functioning" or "milder" range of the spectrum. Although if you are someone or a loved one with the disorder, there is probably nothing that seems " mild" about it. Best wishes.

Difference: Asperger syndrome is part of the autism spectrum. In the usa it is no longer a proper diagnosis, although it does describe a particular pattern within the spectrum. Generally, they have more social interest, they have at least average (often high) intelligence, and they have narrow areas of interest (weather, dinosaurs, pokemon, etc) about which they learn every fact.

Because the same : core deficits - diminished or absent joint attention, facial recognition & Theory Of Mind - exist in all types of Autistic Spectrum Disorder, the diagnoses of Asperger Syndrome & PDD-NOS were subsumed into ASD in the DSM-V. The level of ASD is defined by the type & degree of supports needed for a person with ASD to function optimally, 1 being the lowest level of need & 3 being the highest.
