Can you please tell me how high functioning autism and asbergers differ?

Language and IQ: Asperger's disorder includes people with normal iq's and who had no delay in language development. High functioning autism is a person with autism who has a normal iq and may or may not have had language delays.

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.
